The lump sum contract associated with construction particularly in the Middle East has created untold misery to contract administrators and quantity surveyors working in every sector of the construction industry. The problem is
ABOUT HARIS DEEN, PH.D., MBA, B.SC., FRICS, ACI ARB. (RETD.)
caused by a misunderstanding of the concept of lump sum contracts and the application of the principles associated with such forms of procurement. A lump sum contract is an agreement pursuant to which one party consents to pay another party a set amount of money for completing the work or providing the goods described in the agreement. Typically, lump sum contracts do not require contractors to provide a detailed breakdown of costs. Rather, the payment of the total contract price is linked to the contractor completing all of the work specified in the contract. For example, a software installation company may enter into a lump sum contract for installing multiple data processing systems in a building. Instead of receiving an individual fee for each system installed, the company will receive one fixed amount after it finishes installing all of the systems. Lump sum contracts are regularly used for a variety of transactions, including construction work, consulting projects, and architectural assignments. A lump sum contract is easy to manage since payment is made only once. Generally, the lump sum contractor is paid a flat amount of amount of money after the party receiving the services or goods is given the output. For instance, under a lump sum arrangement, an architect firm is usually paid its total fee once it has supplied all the deliverables acceptable to the Employer.

The construction industry often engages in lump sum contracting. In most cases, the building owner signs a lump sum agreement with a general contractor. The general contractor then enters into separate agreements with

subcontractors. The explanation so far seems simple. Then what seems to be the problem?

Contingencies Despite described as a lump sum contract all the above items are subject to adjustments and additions to and deletions from the bill of quantities is possible if the contract provides for variations, but no remeasurement of quantities stated in the bill of quantities will be allowed. As a rule, construction contractors are not entitled to receive more money than the contract specifies. Items required to complete the works must generally be provided even if they have been omitted from the bill of quantities – (Williams v Fitzmaurice (1858) 3 H&N 844). Michael O’Reilly points out that if there is no mechanism in the contract for receiving payment for these extra items, the contractor will have to pay for them. This means that the contractor will have to provide what is indispensably required to fulfil its obligations under the contract. If it is presumed that quantities do not form a term in lump sum contracts unless the contract states otherwise, the contractor will not be paid any additional payment if the quantities required to be executed are greater than stated in the bill of quantity, (Portman and Fotheringham v Pildritch (1904), Priestly v Stone (1888), Re Ford and Bemrose (1902) CA, Sharpe v San Paulo Railway Co (1873) LR 8 Ch App 597). It could therefore implied that the reverse is also true – being that if the quantities stated in such a bill of quantity are greater than what is required to be executed (as long as the item description is not changed) the contractor will be entitled to receive the full payment against that item. Can the Employer or Engineer therefore, change the description of an item in the bill of quantities where the quantity has been over measured and attempt to remeasure and obtain the lesser quantity? Unless the contract provides to do so, definitely not! Any attempts to do so would mean introducing an element of remeasuring where the contract does not provide and this would be in breach. In the same context, what about an item contained in the bill of quantities which is not required to be executed? Contractors always argue that being a lump sum contract they are entitled to be paid for every item in the bill of quantities regardless of requirement in the same manner that the Employer is entitled to insist upon the contractor to provide items required but missed out in the bill of quantities and that each balances with the other.

I agree with you that the burden of proof lies with the Contractor but in this particular situation he does not need to analyse whole contract bill to prove his case. In a lump sum contract, the specifications and drawings are used to describe and identify the scope of works. BQ (or Schedule of Rates) does not use for this purpose and it is used to value variations and often times used for interim payment valuations.

You don’t seem to disagree with me that the burden of proof of the contractor’s entitlement for payment of a non executed item in a BOQ rests with him.

The Lump Sum Construction Contract – What seems to be the problem? « Dr. Haris Deen should do so. The main point is that anyone should not be entitled to be unjustly enriched by claiming money for work he has not executed. If he can prove that this is money that he richly deserves, then certainly he should be paid. Reply Troy Dias on January 19, 2011 at 8:40 pm. Thanks for your quick response. My point is in a lump sum contracts, BQ does not use to describe or identify the scope of Works. The BQ is a tool we use in a lump sum contracts to calculate the Tender / Contract Price. The scope of Works is defined in the Specifications and Drawings. The Contractor’s obligation is to complete the Works in accordance with the Specifications and Drawings. The BQ may contain items which are not required to accomplish the Contractor’s obligations under the Contract. However, the Contractor should execute any works defined in the Specifications (in most cases Specification takes precedence over the Drawings) even though such works are excluded from the BQ (and/or not shown on the Drawings). I consider that, after the award, the BQ is used only for the purposes of valuation variations and interim payments, unless BQ contains provisional items which are subjected to remeasure. Further, in lump sum (without quantities) contracts, BQ is replaced by Schedule of Rates. In conclusion, I consider that, in a lump sum contract, you can’t simply negate payment for any item in the BQ which are not defined in the Specifications and/or shown Drawings, as the BQ does not identify or describe the Scope of Works. Reply Haris Deen on January 21, 2011 at 11:21 am. You are quoting out of context Troy. My article is based on a BOQ being a contract document. You are right where the BOQ is not a part of the contract. In the ME all contracts I have come across (If I am wrong someone will correct me,) the BOQ is a contract document listed in the documents forming part of the contract and the heirarchy for reference in the event of a dispute. It is always stated that despite the heirarchy, all documents are complementary with each other. That means that the BOQ in this instance is part of the scope and the Contractor will be required to execute all the items in described in the BOQ if it wants to get paid. IT ALL COMES DOWN TO WHAT THE CONTRACT STATES AND THAT IS HOW JUDGES AND ARBITRATORS DECIDE A CLAIM. I have not found any case where a judge or arbitrator (in the frist instance or on appeal)has allowed a claim that a contractor is not entitled for and refused any claim that contractors are entitled to9 compensation. Under the doctrine of restitution no one is entitled to receive any payment for what he is not entitled for under a contract and the converse is also true that the employer cannot escape from paying a contractor his rightful dues under a contract. Reply Martin on June 5, 2011 at 12:00 am.

I noted your comment about the spec takes precidence over the drawings. Reply Haris Deen on June 12, 2011 at 11:44 am. Dear Martin, Your question is not very clear. However, I will try to answer. In the first place addressing the responsibility of the QS – The QS has a duty to provide accurate Bills of Quantities. He cannot expect to shield himself under the ‘Lump Sum’ pretence for his mistakes. As far as the Contractor is concerned he must provide everything that is indispensably required for completion of the Works whether it is shown on the drawings, specified in the specifications or measured in the BOQ. Please read my article very carefully as it deals with different aspects of a Lump Sum contract which will enlighten you more on this subject.
Boon on June 25, 2015 at 5:52 am. Agreed with Troy… Reply Dr. Haris Deen on July 29, 2015 at 10:16 pm. I suggest the topic “Avoiding pitfalls in tendering for Lump Sum Contracts”. In your introduction, you might refer to decided cases – Williams v Fitzmaurice and the San Paolo case, which are landmark cases and build your theseis around them. Good Luck.
Abdulrahim Ostol on July 5, 2013 at 1:26 pm. Dear Sir, I am with the client side our contract with the main contractor is a lump sum although in our General Conditions of contract Clause Variation Order, we have addition and deletion. We deleted items in the BQ which is not required hence the Contractor insisted it is a LUMP SUM price and he is entitle to claim the same value signed in the letter of award and noticed to proceed. Kindly advised as a Client or Owner, do we have the right to claim the negative Variation order, hence contractor also claim that there are some concealed and unforeseen items during tender. It is clear in our General Conditions of Contract that the Contractor before tendering he has the right to verify the site conditions, its drawings, specifications, bill of quantities and to satisfy himself and he has no right in the future to claim any additional cost, what ever missed to price under this contract. However, the client has the right to increase or delete items during construction period not exceeding 20% of the lump sum price. Kindly Advised,

The Lump Sum Construction Contract – What seems to be the problem? « Dr. Haris Deen Regards Abdulrahim Reply Dr. Haris Deen on July 8, 2013 at 1:05 pm. Dear Abdul Rahim, If the Contractor has priced an item that was not required to be executed in any case, at the time of tender, then he was taking a risk. If the item is not required and the Contractor insists on payment for that item, he cannot be paid for what he is not executing. Tell him that payment will be made only for items he has executed and the final account will take into account those items that he has not executed. You do not have to do anything at the moment. Payment should be made only for items identified in the BOQ (if BOQ is part of the Contract) on interim certificates. I cannot give a further clarification without knowing the full facts. Reply Abdulrahim Ostol on December 20, 2014 at 8:11 pm. Dear Sir, The missing amount from the items bill of quantities is required to be executed hence, the contractor missed to fulfill their obligation to checked properly the total amount of the project before awarding, signing the BOQ and signing the contract. After signing of all the documents then the contractor only started to claim the missing value which cost 1.7 Million SR. However, in this case we insist to not to consider this claim by the Contractor since it is their mistake and risk to finalized his BOQ to his satisfaction as per contract documents and Contract is a lump sum, kindly advised if we are right to keep the same contract amount signed. Regard less of any approved V.O’s. Regards Reply Dr. Haris Deen on May 2, 2015 at 5:20 pm. Dear Abdul Rahim, You do not state the FORM or CONDITIONS OF CONTRACT. However, assuming the conditions to be FIDIC or the American Corp of Engineers Form. If it is a Lump Sum Contract whatever the Form of Contract the contractor must execute all works indispennsably required for proper functioning of the works whether included in the BOQ or not

Kasun on February 17, 2011 at 12:29 pm. Thank you for enlightening us. Based on my understanding and experience I am strictly following the below points in all Lump sum contracts that I administrate 1 ) Drawings and specifications are key for defining the scope – YES I agree . However following scenarios are very interesting case 1 : What if BOQ contains a item that is physically possible to do at the tender stage ( irrespective of whether it is related to works of drawings and specifications) but not shown in the drawings and specifications ? My opinion – the contractor is required to do that item and it is possible to instruct omissions on that item case 2 : What if BOQ contains a item that is physically not present on site ( or not required to do even at the tender stage ) and it is not shown in the drawings and specifications ? My opinion – the contractor is not required to do that item and it is not possible to instruct omissions on that item. So no deduction on the contract price is possible for this item. 2 ) Look for the BOQ general items . Check if there is an item that allows the contractor to add items If he believes that due to any reason those items are missing or quantities are not sufficient. IF there is such a provision usually it will be like this “The Contractor shall describe and price below the items necessary for the completion of the work as described in the specification or shown on the drawings and for which special provision is required and which are not covered by the rates in the Bill of Quanties” If so the below No 03 mechanism is applicable 3 ) I follow the following omission and addition concept to price variations If there is provision in the BOQ for the Contractor to insert his items for missing items ( refer Item 2 above ) for example Boq quantity = 10 m ; rate = say 5 $ per m agreed contract price = 10 * 5 + other items = 50 $ + 150 $ ( say for other items ) = 200 $ case 1 : drawing quantity = 12 m if no variation issued then contractor will do 12 m of work and the contract price = 200 $ – this is clear omission ( what the Contractor supposed to do ) = 12 * 5 = 60 addition = 12 * 5 = 60 the contract price change = (60)+ 60 = (0) ; new price = 200

Reply Haris Deen on February 20, 2011 at 11:41 am. Dear Kasun, thank you for your inquiry. From the facts contained in your question, I am led to believe that you are a QS. If I am wrong I offer my apologies. You have not indicated the conditions of contract that you are basing your analysis on. Whatever, the procurement type, Lump Sum, Remeasured, Cost Plus etc., what is agreed between the parties and contained in the document will override any other consideration. A Lump Sum contract is simply what it says it is. The Employer promises to pay the Contractor a Lump Sum Price for what the Contractor has agreed and promised to execute. What constitutes the scope which the Contractor has to do to be entitled to receive the lump sum will be contained in the documents or reasonably implied there from. If you read my article carefully you will find cases I have cited supporting the settled law that in a lump sum contract the Contractor has to execute whatever is indispensably essential for the proper completion of the job as intended by the parties irrespective of whether the work required is shown on the drawings, specified in the documents or measured in the BOQ. The argument usually is the place of the BOQ in the contract. Contractors insist that in a lump sum contract if an item is measured in the BOQ it does not matter whether the item is required or not they need to be paid the full contract sum, as the basis of a lump sum contract. This is only correct if the BOQ is not part of the contract. Even where the BOQ is a contract document and complementary with other documents Contractors put forward the same argument. This argument is founded on the basis that the Contractor will have to execute work not measured in the BOQ or shown elsewhere but

The Lump Sum Construction Contract – What seems to be the problem? « Dr. Haris Deen required without any additional payment as part of the lump sum contract. Where the BOQ is a contract document it is meant to describe the scope for which a price has been submitted and this is settled law. The Contractor cannot be unjustly enriched for work that he has not executed. The item not fully executed can be deleted by the Engineer from the BOQ and the contract sum adjusted accordingly. Of course if the Contractor can prove that he priced the item in question to compensate for any missing items he would be entitled to be paid this item as a variation. If such proof is available, then the Contractor will also have equitable legal remedies. REMEMBER THAT IF THERE ARE NO SUPERFLUOUS ITEMS IN A BOQ AND THE CONTRACTOR HAS TO EXECUTE ALL THE ITEMS IRRESPECTIVE OF ANY DISCREPENCIES IN QUANTITIES THE CONTRACTOR IS ENTITLED TO RECEIVE THE FULL LUMP SUM CONTRACT PRICE. On an issue such as the above, my advice to Contractors and their estimators is not to depend on the BOQ against the work to be executed in a lump sum contract. Be particularly aware of items described and not required to be executed and for items that might have been missed out. Qualifications in a tender submission might not be acceptable, but a subtle tender query indicating a superfluous item in a BOQ and suggesting that the Contractor will price the item in compensation for any particular item missed out. It will stand in good stead if some item can be “concocted” if it is difficult to find one during the time available for tendering. Now, coming to the different measurement areas that you have stated in your query, please understand that you cannot introduce remeasurement to a lump sum contract. If an item in the BOQ is under measured it is the Contractors’ risk and he has to bear it. Similarly, if there is an item over measured it is the Employer’s risk. Any attempts by the Engineer to make any adjustments to such over measured quantities must be resisted. The question sometimes arises where an item described in the BOQ has been changed to another description. For example, if the BOQ indicates 10,000 m² of asphalt road paving and the Engineer wants to change it to interlocking tiles, the variation order will describe an omission of 10,000 m² of asphalt paving and if the quantity that has to actually executed is 10, 100 m² of interlocking tiles, the Contractor is entitled to get paid for 10, 100 m² but calculated for 10,000 m² (The quantity added must be equal to the quantity deleted – the compensation for the additional 100 m² is based on price adjustment). In conclusion, I must stress that you cannot introduce re measurement to a lump sum contract, unless the contract contains provisional items or quantities. I hope that this clarifies the position and if you are still unsatisfied, please fell free to comment. Reply Gishan Nadeera on September 11, 2012 at 8:51 am.

The Lump Sum Construction Contract – What seems to be the problem? « Dr. Haris Deen specification or B.O.Q is not part of the contract documents as they not stamped and signed by the both parties. This Building is 21 floor residential tower in Pearl Qatar and contractor knew initialy the designed no of units was subject to change later. Contractor executed the work. 1.Now contractor is claiming that for the work which is required by UDC which was not shown initially in the drawings, specs or B.O.Q. 2. And also he is claiming some mechanical items which is increased due to the changes of no of units. As per your comment if the B.O.Q is not part of the contract, contractor has to do all the work which is essential to complete the project and I belive the above factors can catogorise the essential work. Therefore contractor not entitle for any variations. Please correct me if I’m wrong. My next question is initial stage installation of the marble and granite was contractors scope and later client gave that scope to a different contractor. In this situation does client have the right to omit the lump sum amount? Thanks Reply Dr. Haris Deen on September 25, 2012 at 10:17 pm. Dear Gishan, Sorry for the delay in responding. In any lump sum contract, irrespective of the documents forming part of the contract, the contract is awarded on the basis of executing a known scope of works. He can price any risks for unknowns within that scope. According to your question, the contractor ‘knew that the initially designed number of units were subject to change later’. You do not however say to what extent did the contractor ‘know what will be changed’. It is unreasonable to expect the contractor to execute work that he did not know what to expect at the time of submitting his tender. Without investigating all the documents forming part of the contract it is not possible to give any authoritative response. However do not expect the contractor to accede to do everything that the employer asks for except such work is within the scope that the contractor offered to do within the contract sum. Reply
Troy Dias on March 20, 2011 at 11:53 am. Whist I still maintain my opinion that BQ should not use to identify the Scope of Works, in the same context I further disagree with you that BQ quantity should be used for the purpose of valuing variations. Generally, in relation to the valuation of variations, standard forms include two important provisions; (a) variations should be measured and (b) valued using rates and prices contained in the Contract (if applicable). Thus, in both omissions and additions, quantities should be measured using the Contract Drawings and the

The Lump Sum Construction Contract – What seems to be the problem? « Dr. Haris Deen revised Drawings. On the same token and in extreme cases, you could deduct more than the Contract Price in case of a variation. For example in a curtain walling contract (lump sum price of 5 million) with BQ includes only one item for curtain walling (1,000 m2 and 5,000 per m2) and CA instructed to change the curtain walling to cladding (rate = 5,050 per m2). In this case, if the measured quantity is only 1,050 m2, then actually the Contract Price will be increased by 52,500 as the omitted value exceeds the Contract Price.

If the contract makes the BOQ a contract document, then it will be part of the scope. Nevertheless, if the contract is a Lump Sum contract, the remeasurable elements are only those mentioned in the BOQ as being remeasurable and that includes provisional sums, provisional items, prime cost sums, and contingencies.
Reply Troy Dias on March 27, 2011 at 2:35 pm. Thanks Dr. Deen for your response. My point is about valuation of variations (i.e. we should measure both omissions and additions, and BQ quanitities should not be used for this purpose). Reply Kelvin Ho on April 3, 2015 at 4:17 am. What is the scenarios if the following situation happened: The Owner and Contractor has signed a Mechanical and Electrical supply and install contract for an service apartment. The building works has completed and the Owner decided to convert the nature of the building to commercial usage such as office building. This will result in less works for the contractor.

Since FIDIC forms are not meant for lump sum contracts, I consider JCT forms (in particular with and without quantities forms) are more appropriate to use for the clarification of the issues. In JCT with quantities, quantities forms part of the Contract, thus, any error in the quantities and/or description becomes a variation. However, when it comes to value variations assuming there isn’t any error in the Bill Quantity, you can use the BQ quantity for both omissions and additions. In this form, in the event an item included in the BQ but such work is not required for the Works (i.e. not in the Drawings or Specification) can be omitted as it is considered as an error in the BQ. On the other form, quantities do not form part of the Contract and the Contracts Bills are merely considered as “Schedule of Rates” (sometimes we include the Contract Bills as a Contract Document, however, it is still considered as “Schedule of Rates”). In this form, variations are valued using the Drawings. However, even if the Contract Bill is listed as a Contract Document, in this situation we don’t use BQ quantities for omissions or additions. In the event provisional quantities are included in the Contract, we shall omit the BQ quantity and measure the quantity from the Drawings for additions. Further, you can’t omit an item included in the Contract Bills (or Schedule of Rates) which is not included in the Drawings or Specification. Please note that I don’t have copies of both forms with me to quote relevant clauses but I appreciate your advice on the above issues if possible please email me the relevant clauses of those documents. I think the main problem the problem is (especially in Middle Eastern countries), we attempt to convert FIDIC forms (which are for remeasurement contracts) in to lump sum contracts (with or without quantities) without amending the essential clauses. I personnel don’t like to use this approach but I think it is time for ME to use JCT forms for lump sum contracts.

Foong on March 31, 2011 at 8:05 pm. Dear Dr. Deen, i’m a bit confused as for a lump sum contract based on drawing and specifications but with the BoQ to be part of the contract document and that the quantities do not form part of the contract, (i) whether the description of items provided in the BoQ also considered part of the specification that we have to provide, i.e material specs stated in the BoQ.

Reply Haris Deen on April 5, 2011 at 2:15 pm. Dear Foong, Thank you for your query, I apologise for the delay in responding because your message was lodged in my hotmail folder which I rarely open. I respond to your queries in the same order that you have indicated as follows: (i) If the Contract (you have not mentioned the Form of Contract) states that the BOQ is a part of the Contract but not the Quantities contained therein, then the contract is flawed. The BOQ is what it is “a Bill of Quantities”. Therefore, in my view to exclude the quantities contained in a document while making the document itself part of the contract, in my opinion is flawed. The principle associated with the BOQ was established in the case of London Steam Saw Mills Ltd v Lorden (1900) where it was held that the quantities in the BOQ in a LS contract are not measurable except in the case of variations. (This was based on GC Works 1 Form of Contract). As far as descriptions and specifications contained in the BOQ are concerned it was established in the following cases that what is stated in the Conditions will over ride what is stated elsewhere. (Gleesons Contractors Ltd v Hillingdon Borough Council (1970) – JCT 1963 Form and Gold v Fotheringham Ltd (1958) – GC Wks. 1 Form). (ii) In a LS Contract the Contractor will be required to do what is “indispensably essential” to complete the works – Williams v Fitzmaurice – However, the phrase “indispensably essential” is subjective and can be misused. Therefore it is established that what is indispensably essential for a palace will be different for a factory building, office building or warehouse. Taking the case cited above it concerns flooring. Therefore the flooring which was not included in the BOQ which was a contract document can be of the minimum requirement for the type of building. On the other point: No the Contractor cannot claim something he has assumed in pricing such an item if he has not indicated what he has assumed when submitting his tender. Reply
Bruce Parry on May 10, 2011 at 11:32 am. I am interested in the continued applicability of Williams v Fitzmaurice (1858) under English Law I assume that the doctrine of indipensability has not been amended by statute or superior decision. I have a situation where the supplier of power plant equipment excluded civil works BUT only the supplier can provide the civil works design for foundations etc. for the supplied power plant equipment i.e. the designs are indispensable. As the supply subcontract is lump sum and under English law it would appear that the indispensable rule applies and that the subcontractor cannot refuse to provide the necessary designs.

The Lump Sum Construction Contract – What seems to be the problem? « Dr. Haris Deen Haris Deen on May 11, 2011 at 9:38 am. Dear Bruce, Without looking at the Conditions upon which the contract was awarded I cannot commit to any authoritative answer. However: 1. The facts supplied by you indicate that the contract was for supply only, the civil works being excluded. If this is the case, then the supplier is obligated only to supply the goods in good order, free of defects under the lump sum. 2. If on the other hand the contract states that the supply includes installation, then it would have been upto the supplier to inquire where and how the equipment should be installed in order to ascertain his responsibilities, in which case he would been told the extent of his involvement in the installation process. In this situation if the supplier went ahead without inquiring as to the nature and method of installation it can be fairly reasonably assumed that he knew of the requirement and Williams v Fitzmaurice will apply. 3. It is normal practice to provide information as to civil works where supply contracts for mechanical and electrical installations, Also normally civil works or builders works are provided separately. Going by the norms of the industry it is unreasonable to insist upon the supplier to provide the foundations when it is not his responsibility. Having said all the above, I must once again reiterate that it will all depend on what the contract states. You need to check the contract, and see where your case will fit in. Good Luck Reply
A Fallon on June 7, 2011 at 11:59 am. In Saudi Arabia they have a tendency to execute lump sum contracts while attaching supporting successful contractor’s as bid quantities and unit prices for payment purposes or to evaluate changes by use of the unit prices. Being a lump sum contract I do not understand why incorporating the supporting BOQ and or bid data. I had a case where the contractor had an EPC project. The engineering portion was to be completed by contractor based on conceptual plans FEED. During the detail design client did minor modification affecting quantities. For instance Building locations were modified which could not be construed as a change because the client had considered the buildings in the original FEED concept and the length of utility between buildings would be paid under the As Bid unit prices by increasing or decreasing the affected quantities after procurement and construction and payment. Contractor went along with client and completed design without formal request for a deviation as they felt they would be compensated later under the actual quantity and unit prices. Contractor orders parts and materials and months later when the construction work is due to start for some portions of the work, Client decides to delete some major equipments and associated improvements from the scope of work and requested a credit for the deleted work.

The Lump Sum Construction Contract – What seems to be the problem? « Dr. Haris Deen Client now wants to delete and be credited for the quantities associated with the approved design engineering completed by contractor. When the client changed the building locations it had actually increased the distance between buildings considerably but now refused to accept credit for the AsBID BOQ quantities. Contractor is now being requested to give a credit that exceeded their bid. Client says contractor should have requested a change deviation months before when the design deviation occurred in order for their concern to be valid. Another issue the client raised is that the contract is a lump sum and that even though the AsBid BOQ was inserted in the contract it meant nothing to the contract. However, Client used the BOQ as the basis to develop and approve monthly payment invoices throughout 70% of the work but when the contractor attempted to give a credit for the deleted work items based on this AsBid BOQ and Payment cash flow schedule that reflected the actual work items, client refused to accept the contractor credit based on this basis. Attaching BOQs to Lump Sum price contracts without validation of quantities and prices and proper Summary of Negotiations before enterlng into a Contract is a mistake. It is better to sign a contract with just one number.
Reply Haris Deen on June 12, 2011 at 12:51 pm. Dear Fallon, As I understand from your explanation, the contract is a design and build (D&B) contract based on a concept provided by the Client and the bid documents included amongst other things the contractor’s BOQ. You do not mention the type of contract used. I assume that it would be FIDIC. Your explanation also suggests that the Client made changes during the detail design stage which “affected the quantities”. Before dealing with the rest of the explanation, later on you also state that the contract was based on “Lump Sum” (LS), suggesting that the LS was fixed prior to the detaile design stage. If this is the case this is an important issue in deciding any claim. Now going back to the second paragraph of your query, you state that the building locations were modified “which could not be considered as a change” but continue to assert that the minor modifications to the quantities occured. If that is the case, the scope has not changed and the contractor cannot expect to get anything more than the LS price (if he has executed the Works to the complete satisfaction of the Client) and the Client also cannot deduct anything from the LS. Assuming that the case is as stated above, the contractor is within his rights to order the parts and materials as stated by you in the third paragraph. If the Client decides at this stage that he needs to vary the scope, of course under FIDIC he is within his rights to do so. In such an event the contractor must be compensated for the materials that he has ordered and brought on site at the time of the Client’s decision to vary the scope. At the same time the Client will be entitled to obtain credit for the deleted works and, since the contractor has submitted a priced BOQ with his bid documents which are now part of the contract, this can be used to determine the extent of the deletion. What you state iin your fourth paragraph is confusing. You are saying that the distances between the buildings has increased due to the change and the Client “is refusing to give credit”!! Why

The Lump Sum Construction Contract – What seems to be the problem? « Dr. Haris Deen should the Clinet give any credit? If at all the Client should pay the contractor for any extra work involved by change in scope. Furthermore, the contractor should have protected his rights by requesting a change order when the Client instructed the change. However, this should not prevent the contractor from claiming his rights, because by conduct the Clinet has accepted the scope change, irrespective of whether the contractor requested the change order or not. A priced BOQ attached to bid documents does not constitute or indicate scope of what is required to be done. The BOQ is only a document that is indicative and used for controlling payments and variations. Please read my article carefully. Reply Cagdas Evren Bayrak on June 16, 2011 at 12:19 pm. Dear Mr. Deen, With all due respect, I am also of the opinion that, submission of BOQ’s during tender phase gives Tenderers the impression that (even clearly its purpose is stated) the BOQ is contractual, and it is hard to explain people that, they are supposed to do everything written in their contract as “lump sum” but get paid on BOQ items basis. It has, and it will, mislead people to think that their responsibilities are bound with what is stated in the BOQ. I think that, in lump sum contracts the payments / remuneration shall ne through a “Schedule of Prices”. If still a BOQ is desired for valuations, etc., it might be requested after the Tender is awarded, i.e. from the Contractor, not the Tenderers. I seriously hesitate on using “Lump Sum Contract with Bill of Quantities” even though it’s widely used, especially in the Gulf region. Reply Dr. Haris Deen on June 20, 2011 at 12:23 pm. Dear Cagdas, Thank you for the comments. However, please remember, the problem is not with using the “Lump Sum” contract form but with the conditions attached to it. Also how the contract itself is interpreted and administered. There is no way that one can genaralise what is contained in a contract. We can though state what needs to be included in a contract to define the scope. To this extent the BOQ should not be used to define the scope. However, once again I stress that what is stated in the contract will override any other considerations, and if the contract states that the BOQ is to be considered a contract document, then that will be the case.

The Lump Sum Construction Contract – What seems to be the problem? « Dr. Haris Deen Some Civil works items are indicated as Lumpsum items, for e.g. excavation, demolition and cartaway, Duct banks, Building water supply system etc. In the tender phase, the building was to be constructed at certain surface level and post award it was decided that in order to meet with local authoritys requirement, the substation level had to be increased by almost 1.5 meters (up wards). Due to this change, Contractor incurred additional expense to bring in extra fill from outside. When a claim was submitted stating that as per tender phase estimation, no (less) fill material was considered and due to change during detailed design the new cost is not foreseen and therefore must be compensated. Client argues that in such event to consider this claim, then Contractor shall calculate the reduction of excavation quantity (please note that both back fill as well excavation was Lumpsum item as per BoQ). Also, tender drawings indicated duct banks on 4 locations, but during detailed design phase it was commonly agreed to make the duct banks in 3 locations. Now, Client wants Contractor to calculate the reduction in length and consider as varied quantity. Kindly advise what should be Contractor’s action now?

Renard Baudrillard on December 13, 2011 at 1:22 pm. Dr. Deen, I would appreciate your clarifying the following in your response to Kasun on 20 February 2011: You state that “The Contractor cannot be unjustly enriched for work that he has not executed. The item not fully executed can be deleted by the Engineer from the BOQ and the contract sum adjusted accordingly.” I am assuming that by “fully executed” you mean executed at all and not partially executed given your subsequent comments. For if the item is to be deemed superfluous, it must mean that it is not executable – a qualitative question – and not partially executable – a quantitative question. But this is where I think most of the disagreement arises in LS contract administration in the Middle East. At what point does a reduction in scope (amenable to omission by the Engineer) end and remeasurement begin? If there is an item in the BOQ (that is stipulated to be a contract doc) for laying 20,000 sq. m of interlock tile and the Contractor ends up executing 10,000 sq. m because site conditions end up differing from drawings based upon which the tender was prepared, is this a reduction in scope?

The Lump Sum Construction Contract – What seems to be the problem? « Dr. Haris Deen 19,000 sq. m for the same reason? As I see it, the issue is an equitable one – is the Contractor unjustly enriched? For there is no hard and fast rule. In the first scenario, where the quantity was halved, I believe the general sense is that paying the contractor for the full quantity would be a windfall and the contractor must raise a defense to unjust enrichment in the form you prescribed – arguing that the value was shifted from an unquantified item. In the second scenario, where the actual quantity was 5% less than the BOQ quantity, any omission would be tantamount to remeasurement, which generally speaking is not contractually permitted under typical LS contracts. If I am incorrect, that is if in adjudicating these types of disagreements some “common” law has emerged – what is the test? If I am correct, that is if determining whether we’re confronted with a valid reduction in scope versus a remeasurement turns on the issue of unjust enrichment, then I believe a more thorough examination of this legal concept must be more broadly disseminated to the Middle Eastern CA community.

Like plaster to block work for receiving water proof behind retaining wall. I did not price it during tender, but I was asked to say it is included as it is a rule that no item can be excluded, so I did so. Now the site requirement is plaster is not required and water proof can be done without it. Now does the engineer have the right to deduct the price of plaster taking the rate of normal plaster from the BOQ. The drawing shows that plaster should be done to receive water proof. The Engineer says since it has been shown in drawing but not done at site since it was not required it shall be deducted. I would agree if I had priced it but it has not been priced and I stated its included in my price. What is your opinion. Thanks

On your questions, please also keep track of the Q&A section because there are authoritative answers therein. Now coming to your specific question regarding the statement that the “BOQ is guaranteed and forms part of the Subcontract” is very interesting. I believe that this a document produced by the Main Contractor for the subcontractors to price. The idea of providing such a qualification is to ensure that tendering subcontractors all price at the same level and the same document and therefore comparison is easy. However, by doing so what the Main Contractor is in fact saying is that he is warranting the quantities contained in the BOQ as accurate, any inaccuracy therefore will amount to misrepresentation (Wood, R.D; Claims under GC Works 1). The position of the BOQ in a Lump Sum Contract is the same insofar as the scope is concerned. The quantities are not to be remeasured and the Subcontractor (in your case) will have to be paid for all the works described therein as long as he has executed them (of course subject to adjustment of provisional sums, provisional items, prime cost sums and contingencies) If the quantities warranted are grossly incorrect then the Subcontractor will have a claim for misrepresentation under the common law of Australia. It is therefore clear that, irrespective of what the qualifications are, no remeasurement is warranted in a lump sum contract where there is no change in the scope. Having stated the above, I would hasten to add that what is stated in the Contract read as a whole will override any other considerations. Reply

After accepting the conditions and signing the contract freely, he cannot now complain that he is incurring losses. That is teh name of the game.

Steven on March 30, 2012 at 6:46 am. Dr Deen I have two questions: 1) Is there any practical or substantive difference between a contract expressed as a “lump sum measure and value” contract to a “schedule of rates contract” where both contracts contain what is often the case called a “Schedule of Rates – Bill of Quantities”. Does it depend on whether the quantities have been provided by the client or the takeoffs are the contractor’s own? 2) I am reviewing a civil contract which provdes that the principal does not give any representation or warranty concerning the completenes of the schedule of rates or the accuracy of the estimated quantities shown in the schedule of rates. However a limit of accuracy does apply to the contract rates. It is a lump sum and SoR contract, but the only lump sum component will be fixed preliminaries and all other costs will be provided as rates in a BoQ. The Principal has supplied the quantities. Do I need to make it clear that this is a SoR contract as opposed ot a lump sum? Or as per above, can I call it a lump sum measure and value? If a lump sum m&v – does this mean that the contractor takes risks on items notwithstanding that a limit of accruacy will apply on all rates? Do I need to make it clear that the quanities are Principal supplied and the BoQ forms part of the contract? I hope this isn’t too confusing. Thank you Steven (Australia)
Reply Dr. Haris Deen on April 4, 2012 at 10:15 am. Thank you Steven for contacting all the way from ‘Down Under’. 1. My understanding of a “Lump Sum” contract of whatever nature is that for the “Lump Sum” stated in the contract the contractor is required to complete the works providing whatever is indispensably required for its construction (Ref: Williams v Fitzmaurice). However a “Lump Sum” measure and value can only mean measuring the executed works for interim payments. Any interpretation otherwise would mean introducing a ‘remeasure element’ to a “Lump Sum’ contract. A schedule of rates is a very useful instrument in the evaluation of variations and if included should be used only for that purpose. Of course having said this I must clarify that what is stated in the conditions or particular conditions of the contract will override any other considerations.

This is perfectly in order, but must be clearly defined in the contract conditions as to how this should be administered.

Naveen on April 4, 2012 at 11:15 am. Dr Deen I am working in the Middle East Public Sector as a Q.S. The contract I am referring to is a JCT Lum sum contract without quantities .The Tenderer was given the Schedule of Item for the contract or u can say a blank Bill of Quantities and the specifications.The Tenderer is supposed to calculate quantities from the drawings and insert his rate as per the specifications. During Tender evaluation,it is found that the lowest Tenderer has calculated quantities on the lower side as compared to other Tenderers & also as compared to the quantities calculated by us for Budget estimate. The Tenderer was offered a opportunity to explain the deviation in quantities but has failed to justfy the same. Should he disqualified which I firmly believe or should his bid be accepted since the contract is as per the Lump sum contract & is based on Drawings and specifications?
Reply Dr. Haris Deen on September 26, 2012 at 9:32 am. Dear Naveen, Thank you for your query. The procedure stated in the JCT for correction of arithmetical errors in a tender is the universally accepted principle. In every tender, whether under the JCT, FIDIC or any other Condition of Contract, the basic principle is that what is stated in the Form of Tender (FOT) is the tender sum, however computed or calculated. If this sum is different when any arithmetic check is made on the BOQ or other computation, and errors noted, whether such errors make a difference in the bottom line total, that is carried to the FOT or not, the error must be intimated to the tenderer and he must be asked whether he is prepared to stand by his tender or withdraw same. FIDIC does not indicate any methodology for dealing with arithmetic errors in this manner, because FIDIC is intended for international use and the principles involved will depended on the culture and policies of the country or client opting to use FIDIC. For example, in most countries of the Middle East, where the arithmetic check reveals a lesser amount in the bottom line total than that stated in the FOT, then the tenderer is asked to reduce his bid to that amount. On the other hand if the bottom line figure is higher that what is stated in the FOT, the tenderer is asked to accept the FOT sum with corrections to the BOQ.

Dear Dr. Deen: I work for a General Contractor and recently I submitted a value Engineering proposal to replace concrete retaining walls (stone cladded finish) with Earth retaining system (geogrid walls where stone cladding is not required). Our contract FIDIC 87, states that savings are split 50/50 between Employer and contractor. When the numbers were worked out for the proposal, stone caldding was not included.

Gary Jones on April 11, 2012 at 10:03 am. Dear Sir, one a lump sum contract is in place, how would you expect the relationship to be between both parties i.e. owner and contractor. For example should the owner actively try and work with the contractor to ensure that the contact price is doable, since we often see the owner trying to control the contractor such that it almost ends up like a reimbursable condition with a lump sum contract. Basically what I am trying to say is how much should we allow the owner to get involved with the actual works during EPC?
Reply Dr. Haris Deen on April 21, 2012 at 11:12 am. Dear Gary, Whatever the nature of the procurement strategy is, whether lump sum or remeasured or something else, project managers always like to work as a team with everybody involving in project execution towards a common goal. However from your question am I to understand that the Employer is interfering to the detriment of the project? In any event, there is no way that the Contractor can prevent the Employer’s involvement to oversee or ensure that his requirements are met. If such involvement causes variationa or causes the Contractor to incur costs that were not foreseen then the Employer must pay the Contractor these costs. When the Contractor submits his tender, it is his responsibility to ensure that the Contract Price is “doable”. Similarly, if the Contract Price was so low that would cause problems for the Contractor and knowing this full well, the Employer has awarded the Contract, then the Employer must suffer the consequences as much as the Contractor. There is no such responsibility on the Employer to

Dear Sir, 1.If the contract is Lump Sum all the variations can be re measured?, which are apart from the provsional sum and optional items. 2.In the same lump sum project Consultant used to revised the contract sum when issuing the variation order, hence still is it valid to remeasure? Kindly help me on this. Thanks Dinesh
Reply Dr. Haris Deen on April 23, 2012 at 12:09 pm. Dear Dinesh, Yes, variations irrespective of the nature of the contract – lump sum or remeasured, usually are treated as remeasured unless the Engineer and the Contractor agree a lump sum price prior to execution of the variation. If you are referring to the Qatar General Conditions, then Clause 51 gives the right to the Engineer to issue instructions that will vary the Contract Price without vitiating or invalidating the Contract. Therefore, the practice of indicating a change in the contract price in a VO is usually acceptable and good practice. Reply Dr. Haris Deen on June 19, 2012 at 1:06 pm.

The Lump Sum Construction Contract – What seems to be the problem? « Dr. Haris Deen bids during Tender Evaluation are dealt with differently in Lumpsum JCT & FIDIC Building contracts. The contract I am referring to is the contract without quantities wherein the drawings and specifications form the basis of the contract and the Tenderer is given a Blank Bill of Quantity with schedule of items and rates and quantity to be filled in . In FIDIC the SOR are arithmetically checked and if any errors in SOR the Form of Tender sum is corrected and the Tenderer has to abide by the new Form of Tender sum. If the Tenderer does not agree to correct the errors the bid is disqualified. But in JCT as per Series 2 ,Practice Note 6, the bid submitted by the lowest Tenderer shall be opened and checked arithmetically.There are two alternatives to deal with arithmetical errors. First option is that the arithmetical errors should be pointed out to the lowest Tenderer and he has option to stand by the original Form of Tender sum or else withdraw.That is no correction in price is permitted.If the Tenderer elects to stand by his tender then the total amount of error is expressed as percentage of the correct total of the BOQ. In the 2nd option, correction of Tender price is permitted.In both cases opportunity is given to the lowest Tenderer to stand by his original Form of Tender sum but this is not the case in FIDIC wherein no opportunity is given to the lowest Tenderer to stand by his original Tender bid price i.e Form of Tender sum. How is it that there are two so divergent ways of dealing with arithmetical errors in building contracts? Which do u feel is the correct way to go about dealing with arithmetical errors in Tender bids for Lump sum building contracts based on drawings and specifications? Is it correct to alter the Form of Tender sum for arithmetical errors in Lump sum Building JCT contracts without quantities?

Dear Dr. Deen: I work for a General Contractor and recently I submitted a value Engineering proposal to replace concrete retaining walls (stone cladded finish) with Earth retaining system (geogrid walls where stone cladding is not required). Our contract FIDIC 87, states that savings are split 50/50 between Employer and contractor. When the numbers were worked out for the proposal, stone caldding was not included. After the approval was granted from the Employer through a variation order, we tried to claim the saving on the stone cladding. The Engineer (who also missed the stone cladding while reviewing our proposal) is refusing stating that stone cladding is not included in the value engineering structural system and thus unwilling to share the saving with us.

The Lump Sum Construction Contract – What seems to be the problem? « Dr. Haris Deen Thank you for your query. I believe that I have already responded to this query. However, any VE proposal under FIDIC should take into account all that is removed or deleted in replacement of the alternative work. In your case the stone cladding was part of the works priced for. Therefore, irrespective of whether you and the consultant, inadvertently failed to take into account the stone cladding during the VE assessment, does not matter. In calculating the final analysis everything that constitutes the deleted work should be taken into account and similarly everything that constitutes the replacement works must also be taken into account. You should ask the consultant, if the intention was the deletion only of the said works, then would he have not taken the stone cladding into account to make the saving? Reply
Muhammad on April 24, 2012 at 1:54 pm. Dear Dr. Deen, Nice and interesting to read your article. I am new into project management. I have a query which is little bit different and awkward. In one of my projects (which is Lumpsum Contract), I have changed the original structural steel to Pre engineered Building with the consent of the Client. At the end of the day, the quantity of steel as per the revised design was 40% lower than what was in the original design. The client demands for a negative variaton to be deducted from the other positive vairations. Is the client right? Or I am eligible for the quantities as per original design.
Reply Dr. Haris Deen on April 26, 2012 at 9:29 am. Dear Muhammad, I am flattered that Project Managers also visit my blog. Keep doing so, because very soon I will be writing on Project Management as well. Coming to your question you have not stated the Form of Contract upon which your contract was awarded. However my response is as follows: 1. Irrespective of the form of contract, what you have suggested is a change in the scope and in a lump sum contract a change in scope will be treated as a variation. The net result (addition or deletion) can be decided on remeasure basis (as this is a scope change) or as a lump sum adjustment. Since the proposal to change the scope came from you as contractor, then the Employer has the right to ask for a reduction as in your case, or if the change itself results in an increase, the Employer can refuse to pay the increase, depending on what you as contractor agree with the Employer. On the other hand if the scope change was instructed by the Engineer and results in an addition or reduction beyond the permitted 20% in aggregate – under Qatari Law 26, then you as contractor will be entitled for new rates on the work which exceeds beyond 20%. That means, if the aggregate value of the varied works, say works out to 50% of the contract sum, then upto 20% of this value the Engineer will apply the contract rates. The next 30% will have to be agreed with the contractor. 2. If the Form of Contract used is the FIDIC Red Book, it could have

Dear Dr Haris Deen, I hope you remember me as one of your students in “Claims Seminar in Qatar” last April, I will appreciate if you advise me about the following case: I am a contractor with LS contract, BOQ is not mentioned as a contract document , but there is a BOQ signed and stamped by the two parties (again it is not mentioned anywhere that it is a contract document) – I am new to the company now the client is asking to change some items like Aluminium works to uPVC, they want to buy materials themselves and let me fix, in addition he delayed decision in many submittals (delay documented). Can you help me in dealing with this?
Reply Dr. Haris Deen on September 26, 2012 at 9:31 am. Dear Musa A Alnatoor The BQ if included, whether stated as part of the contract or not, should nevertheless be accepted as a contract document for reference as both parties have stamped and accepted the BQ as such by signing and stamping the document. However, the BQ should not be used to decide the scope of work to be executed because, as you say that it is not mentioned as forming part of the contract. It is usual (and accepted practice) in the construction industry to use the BQ (if provided) for pricing variations. It is perfectly in order for the client to vary the materials for different or in your case cheaper materials to effect savings. However, by procuring the uPVC materials himself the client has denied the contractor (yourselves) from any trade discount or profits that you might have made from the procurement of the materials. Therefore, in my opinion, you are entitles to receive profits on the cost of the materials. I am afraid that I cannot help you any further on this matter without knowing all the facts by investigating all the documents within the contract. Reply

The Lump Sum Construction Contract – What seems to be the problem? « Dr. Haris Deen conclude on an agreement and sign it; however, courts may not consider some of its terms and/or conditions although parties had previously accepted them. In other words, I want to say that a Contract does not make the law (nor justice). An Employer can not, from one hand, offer to his Contractor an agreement on a lump sum basis, then from the other hand he entitles himself in the same agreement to ‘review’ up/down the lump sum amount subject to the variations that he may order during the performance of the Contract. This is unquestionably an UNFAIR DEAL, and courts may decide unexpected awards at this respect. Surely, the issue is more critical (from the Contractor’s side) when it comes to variations reducing the amount of the Lump Sum; however, we must keep in mind that even for the case of variations resulting in a increase in the lump sum amount, not all Contractors are motivated to perform them (one of the reasons is related to their very busy workload plan). I would highly recommend that all parties to an agreement must give high consideration to the way they draft that agreement in such a manner to make it based on a clear FAIR offer to all of them. In conclusion, I want to sat that Employers being ‘too’ smart in the way they draft their agreements may not always work out as they would have wished. Mourad KRICHEN Contracts & Procurement Engineer
Reply Dr. Haris Deen on September 26, 2012 at 9:30 am. Dear Mourad, Thank you for your comments on my articles on the Lump Sum contract principle and documentation. You do not however support your opinion with authority. You are advised to read my articles on the laissez faire doctrine in the formation of contracts. This doctrine has been succinctly explained by the British Judge Sir George Jessel MR in the case of Printing and Numerical Registering v Simpson (1875) LR 19 Eq 462 thus: “If there is one thing which more than another public policy requires it is that men of full age and competent understanding shall have the utmost liberty of contracting, and that their contracts entered into freely and voluntarily shall be held sacred and shall be enforced by Courts of Justice” Furthermore Lord Pearson in Trolloppe & Colls Ltd v NorthWest Metropolitan Regional Hospital Board [1973] stated: “The basic principle is that the court does not make a contract for the parties. The court will not even improve the contract which the parties have made for themselves, however desirable the improvements might be.” Therefore you can see that all documents forming part of the contract will be enforced by the courts, unless the contract has been entered into under duress.

Robert H Drouin on July 7, 2012 at 8:20 pm. Dear Dr. Deen, Thank you for the very interesting and helpful blog ! As I discovered your site while searching advises and definitions, I would like your opinion on a contractual and legal matter: We have a Lump Sum construction contract were we must indicate our manpower, amongst other quantities information and itemised details, which we did, through the overall estimated manhours and histograms by trade. There is no where mention of manhours in the whole document, but only manpower. In the definition of terms, neither “manhour” nor “manpower” are shown. Although the Client said this is not necessary in his control system,he is requiring that we produce our manhours per item of the construction scope of work. As we are on a Lump Sum, we fear that the Client may come back during the project to try and compensate some change orders with hours that we have gained in productive items (in case of substancial claim and if the overall productivity was good, it happened that the justice would only compensate for the actual difference between the bidded hours and actual hours spent, which would generate a large loss for the contractor). What are the risks and negative impact that may occur if we present our detailed manhours per item? Could you please give me your opinion on the matter? Thanking you in anticipation and best regards, Robert Drouin, P. Eng, MBA
Reply Dr. Haris Deen on September 25, 2012 at 10:15 pm. Dear Robert, Sorry for the delay in responding. Firstly, I was researching for any cases to support my response, but I could not find any specific ones. However, following the rulings in San Paolo and Williams v Fitzmaurice, any lump sum contract is executed on the basis that the contractor has to execute all that indispensably required to complete a known scope of works. Extending this principle it is reasonable to suggest that how the contractor has priced the bid in a lump sum contract is a matter for the bidder and should not affect the payment terms. Having said this, I must clarify that project managers often require the breakdown of the rates in the manner you have stated. This is purely for the purpose of evaluating variations and should not be used for valuing the utilisation of resources in execution of the Works. This is the best I can do without access to all the documents forming part of the contract. Reply

In our Lump Sum Contract it is mentioned that the haulage distance for dumping the excavated material from the Construction Site to the Dump Site (tip) (to be provided by the Client) is 45km.

The quantity may be equal to, less than or more than what was deleted. It does not matter. Dr. Haris Deen Reply

Mountasser on April 16, 2013 at 11:25 am. “Such contract the contractor’s obligation is defined in wide terms. His obligation is to complete the whole of the works. The works have not been described in great detailed as would be in a bill of quantities. “The shorter and simpler the description of the work to be carried out, the more difficult it will be for the contractor to contend that work is extra” (Uff, 2009). The additional work for the foundations will not entitle the contractor to an extension of time because it is part of the widely defined scope of works and therefore included in the original time for completion. “Such necessary works are not extras, for they are impliedly included in the lump sum” (Furst and Ramsey, 2006). This is clearly demonstrated in Sharpe v San Paulo Railway Company where the contractor had agreed to build a railway between fixed termini for a lump sum. Included in the lump sum was excavation of just over two million cubic yards which was calculated by the engineer. It turned out that actual volume of excavation was in fact just over four million cubic yards. The contractors claimed they were entitled to a great deal more due to the understated engineer’s specification. However the court of appeal held that the contractors could not claim for the additional excavation. As per Sir W.M. James, L.J.: In this case the contractors undertook to make the railway, not to do certain works; but they undertook to complete the whole line, with everything that was requisite for the purpose of completion, from the beginning to the end; and they undertook to do it for a lump sum …” That is the risk that the contractor takes on a widely defined scope of work and he must judge for himself and be satisfied that he has allowed for all that would be necessary to complete the works.” This is quoted article from other essay but useful, great job thanx D.

Reply Admin on May 22, 2013 at 6:20 pm. Dear Rey, Thank you very much for your query. There are two issues connected with your question. Firstly, Law No. 26 is intended to protect Contractors, particularly in respect of lump sum contracts. Please remember that the 20% increase or decrease is from the total contract sum and not from individual items. Also it does not mean that the Engineer cannot increase or decrease the scope of contract beyond 20% either way. He can, but the Engineer must compensate the contrator for loss of profit if there was a decrease and different rates if there was an increase. In your case,I would not allow the contractor to remeasure the ducting on m2 basis when he has submitted a “Lot” price. He must be made to provide a proper breakdown of the “lot” price to obtain a rate. Keeping in mind that Law 26 applies only when the omissions or additions are in excess of 20% of the total contract

Simon Mattimoe on August 20, 2013 at 1:59 pm. Dr. Harris Dean, We are currently working on a Lump Sum Contract. We are “back to back” with our sub contractors. The client issued stage D information including a schematic. The Stage D estimation did not show any earthing cable sizes. We made an allowance of 95mm. The total allowance for the earthing installation was £40,000 including earth bars, cables and terminations This is clearly identified in the Contract pricing schedule. The client issued Stage E information. The new stage E information upon which the contract is based showed all earthing cables as 300mm on the schematic in small writing at the edge of the page. The sub contractors estimator appears to have missed the change from the 95mm cable to the 300mm cable. The client now wishes to reduce his 300mm cable to lower sizes. The client is seeking monies for this reduction. Each meter that we give back based on a 300mm cable means that we are giving back more than we had included within the bid. Within our quantified schedule of rates which forms an appendix to the contract (although containing errors) clearly states 95mm. However the schematics from the designer clearly show 300mm cable. Is there an argument to only omit the 95mm cable that was included? Is there a case for “what didn’t go in can’t come out”? Normally under a lump sum contract we would value the variations on their own merit. If we do this on this occasion we will give back more than what we have allowed as well as still having to buy the smaller earth cables, earth bars and terminations with £ Money. We wish to present a case on behalf of our sub contractor to avoid

Reply Dr. Haris Deen on September 19, 2013 at 7:05 am. Dear Simon, I am afraid that any argument that you present in support your subcontractor is likely to fail, unless you have requested clarification of cable sizes at the tender stage and 95 mm was confirmed. Or if you had stated that in the absence of cable sizes you had priced the earthing cables for 95 mm, then you can fight a case. It appears from your comment that neither of the above has happened, therefore it would appear that you might have difficulties here. However, you may use your quatified schedule as a basis and put forward an argument, using any pricing notes that your sub contractor might have, and supported by prices from recognised cable suppliers that the prices of 95mm and 300 mm cables are obviously different, then an arbitrator might support your case as a genuine mistake, depending on the nature of the argument that you are prepared to put. Good luck Reply

On contract award it was realized ‘Provisional sums’ item and amount are mentioned in BoQ, but there in no clause within bespoke contract conditions for Provisional sum. Shall this item be treated as lumpsumfixed price. What external document would lawfully substantiated for the “Provisional sum” definition to the Client/Consultant?
Reply Dr. Haris Deen on September 19, 2013 at 6:52 am. Dear Amar, No, If the sums have been stated as provisional sums in the contract BOQ and the BOQ is a contract document, then these cannot be treated as lumpsum fixed price. Please refer to FIDIC Red Book SubClause 13.5 Reply
Sancho on October 12, 2013 at 1:30 pm. Dear Harris, This is another issue I encountered recently as a Contract Administrator in one project I am handling in MENA region. I am in the Client side. The lump sum contract attached 2 documents – Scope of Works & BOQ. Many clauses in the contract always mentioned about the Scope of Works, but BOQ has never mentioned in any of the clauses. In one of the notes in the Scope of Works, it states that “In case of discrepancies, this Scope of Works takes precedence over the BOQ.”. The fact is that there are many discrepancies between the BOQ & the Scope of Works, BOQ favors the Contractor, Scope of Works favors the Client.

The Lump Sum Construction Contract – What seems to be the problem? « Dr. Haris Deen The Problem: Though all pages in the Contract were all signed by both parties, the Scope of Works (as annex to the contract) was only signed by the Client (no signature from Contractor). While in the BOQ both parties have signed. My Question: Between these 2 conflicting documents, which should governed? Please need your opinion. Thanks Sancho
Reply Dr. Haris Deen on October 12, 2013 at 3:18 pm. Dear Sancho, Based on the following decided cases: Williams v Fitzmaurice (1858) 157 ER 709 Walker v Randwick Municipal Council (1929) SR (NSW) 84 and the famous San Paolo case, no single document decides the scope. Unless I have access to all the documents submitted during the tender I cannot give a proper opinion. The BOQ does not decide the scope. The contractor will be required to do everything required for the completion of the intended projects with the minimum requirements, unless anything else is specified. Dr. Haris Deen Reply Sancho on October 12, 2013 at 3:37 pm. Dear Dr. Harris, Thanks for reply. The Contractor refuse to do some items of work mentioned in the Scope of Works as they cannot found in the BOQ. Thus, the Contractor stands firm on BOQ as it is signed by both parties, while in the Scope of Works only the Client signed it. The project is not completed as Contractor refuse to execute unless it is treated as variation order, say “Roadway Markings & Signs” is stated in the Scope of Works but is not found in the BOQ. Regards, Sancho Reply
Sancho on October 14, 2013 at 1:42 pm. Dear Dr. Harris, I have another inquiry. If any of the pages or its appendices of the contract not signed by one party (say only Client signed), can it still be binding? Or that particular page incompletely signed can be considered ineffective or still binding? Our contractor dispute the Client as one clause is pushed by the client to the contractor to comply. But Contractor rejected as that particular clause page is not signed by him, only the client signed it. Please advise. Regards, Sancho

Dear Dr. Harris, Another issue regarding lump sum contract wherein construction of temporary facility structures are included in the contract scope of works to be implemented by the Contractor. My question is who will be the owner of these temporary structures after completion of the project, is it the Client or Contractor? considering that it is stated in the scope and BOQ to be provided by the Contractor. For example, the temporary security fencing of the camp, is the Contractor have the right to take it back after completion of the project? Of course he will use this one to their next project.

Vladimir on February 14, 2014 at 11:32 am. Dear Dr. Haris, I would appreciate some help on Lump Sum contract issue. On a Lump Sum Fixed price contract where Pricing Schedule used to evaluate variations and for interim payment, significant mistake in quantities was noted. I will explain. Pricing Schedule was prepared by the Consultant, but the Trade Contractor was to remeasure all quantities and add/omit any work as required and in line with tender drawings and specification. Pricing Schedule included for 110 doors. During the tender period addendum drawings were issued and clearly showed only 40 doors required. The Trade contractor didn’t adjust qty of the doors and priced for 110 doors instead of 40. At the same time some other quantities were adjusted by the Trade Contractor. Lump Sum Fixed Price agreement was signed. Can the Consultant reduce contract sum accordingly? Or shall the Trade Contractor be paid for 110 door even so only 40 door installed? Regards Vladimir
Reply Dr. Haris Deen on February 14, 2014 at 7:31 pm. Dear Vladimir, Your case is a typical lump sum contract and you have explained your problem correctly making it easier for me to express an opinion. Let us take a hypothetical situation where your QS has indicated 40 doors in the Pricing Schedule instead of 110 doors and 110 doors are actually required, would you then agree to pay the Trade Contractor for the additional 70 doors? of course not. You will obviously adduce the argument that this is a Lump Sum Contract

You will be in breach if you try to reduce the no. of doors now. If your QS made the mistake he must bear the consequences and the risk is with the Owner. Reply Alexandra on October 19, 2014 at 5:34 pm. Good afternoon Dr. Deen, I am new to the construction industry and have been following your articles with great interest. I am slightly confused about this comment. If the contractor can claim for the 110 doors even though only 40 were installed, wouldn’t this be the same as claiming for works not executed and therefore, unjustified enrichment? Reply Dr. Haris Deen on November 13, 2014 at 4:34 pm. Dear Alexandra, I believe that I responded to your query. It depends on the state of the BOQ as to whether it is contract document. If 110 doors have been measured but only 40 doors are needed, then certainly the contractor would have noticed this at the time of tender. If the contractor can proves that the cost of 70 additional doors will compensate him for items missed out from the BOQ which he is required to provide under the LS contract, then he will be entitlled for the additional 70 doors. The contractor is certainly not entitled for payment where he has not excuted work and conversely the Employer is not entitled to get the contractor to do work without any payment Reply
Faizullah on March 16, 2014 at 6:02 pm. Dear Sir, We have a problem in one of our Contract which is based on Qatar General Conditions of Contract. It is lump sum project. The Contractor and Employer agreed on cost and time of a variation work and VO signed by both of them. Later on it was realized that Contractor has wrongly valued the works and even the Consultant did not check and hence variation order is now closed. My question is ” Is there any way to reopen this variation order”? thanks and regards,
Reply Dr. Haris Deen on March 19, 2014 at 9:05 am. Dear Faizullah, Thank you for your query. Unfortunately the General Conditions do not provide for any corrections of a VO after agreement. Also remember that the VO is issued only after both parties have signed it, The Contractor should have noticed this before signing the VO. Having said this, if you can prove a genuine mistake the Consultant and Engineer might act reasonably to correct the VO. However, they are at liberty to reject as well since it is the Contractor’s responsibility to ensure correct pricing of the VO.

Reply Dr. Haris Deen on March 19, 2014 at 12:50 pm. Dear Faizullah, Yes you might try under Articles 130 to 133 which states as follows: Article 130 1. Where a contracting party commits a mistake without which he would have not given his consent to the terms of the contract, such contracting party may demand voidance of the contract if the other contracting party commits the same mistake, or knows of its occurrence, or could easily have detected such mistake. 2. However, voidance of a contract in respect of gifts may be requested without taking into account the other contracting party’s participation in the mistake or his knowledge thereof. Article 131 The effect of the mistake shall be enforced even where it applies to the rule of law concerning any matter of the contract. Article 132 A party whose consent was the result of a mistake may not insist on such mistake in a manner contrary to the principles of good faith. The other party may, in particular, insist on or plead to the conclusion of the intended contract, provided that substantial harm is not caused. Article 133 The validity of the contract shall not be affected by mere arithmetical or writing mistakes. These errors must, however, be simply corrected by mutual agreement between the parties. However it depends on how you submit your claim. The statements are important to establish mistake from both sides or malicious intent from the Engineer. Reply Faizullah on March 19, 2014 at 1:07 pm. Dear Sir Thanks for your help. My last question is that the proof of malacious intent of engineer would be difficult but it can easily be proved that Engineer was negligent in assessing or valuing the varied works. Regards Reply

The Lump Sum Construction Contract – What seems to be the problem? « Dr. Haris Deen David C on July 27, 2014 at 10:54 am. Dr. Deen I have read your article and the numerous contributions and examples with interest. This is an ongoing basis for dispute in the ME. To my mind Employers in the region are trying to achieve the advantages of remeasurement and the advantages of a lump sum contract in the same contract, without the risk associated with either model. Where quantities and items not allowed for in the Bill are required, they refer to the lump sum basis of the price and expect the Contractor to have allowed for such in his price. Where they believe that the quantities in the Bill are overstated (normally prepared by the Employer), the refer to the Doctrine of Restitution (or unjust enrichment) claiming that the Contractor cannot be paid for work not executed. If the Doctrine can be used in the way suggested, the unjust enrichment could be the simple overstatement of quantities in the Bill prepared by the Employer and the Employer is then entitled to remeasure when it is financially advantageous to him, on the basis that the work was not executed, which happens frequently in the ME. I don’t believe that this interpretation of the doctrine is correct. My view is that if the Employer wishes to vary the scope of the Contract, the rates in the Bill should be used to evaluate the value of such a change and no further. This change, however, must be based on a change to the drawings and specifications on which the tender was based. If your contention that the Bill is a part of the scope definition (and I don’t agree with that statement), the Employer could change the scope simply by changing or defining the quantity of an item required, thereby effecting a re measurement, a practice that is not uncommon in the ME. In my view, the basis of a lump sum contract is that there can be no re measurement, constructive or otherwise. The incorrect statement of a quantity in the Bill does not unjustly enrich the Contractor given that he is required to check the quantities and establish items not included in the Bill and include for such in the lump sum Regards
Reply Dr. Haris Deen on September 24, 2014 at 9:53 am. You are absolutely right David. Employers in the ME region are getting away with “murder” and consultants are no better. I had suggested to several contractors to test this in courts and they have not dared to do so for fear of losing contracts. However, prudent contractors price this as a risk. That may be the reason why some contractors make massive profits while the less fortunate ones lose money. Hope wiser counsel will prevail and some contractor has the courage to test it in courts.

The Lump Sum Construction Contract – What seems to be the problem? « Dr. Haris Deen dispute item araise from the Lump Sum Contract Omission Item. We have consider the following: 1) Contractor did not make any adjustment in the Tender Adjustment Schedule during the tender stage. Scenario One 1) Pricing Schedule (BQ) – 5nos x QR200k = QR1mil 2) Contract Drawing (Actual) – 3nos For the omission items, do you omit 3nos x QR200k = QR600k from the Contractor? Scenario Two 1) Pricing Schedule (BQ) – 5nos x QR200k = QR1mil 2) Contract Drawing (Actual) – 8nos For the omission items, do you omit 8nos x QR200k = QR1.6mil from the Contractor? Please advise : 1) If there is a limit during the omission (capped at BQ amount)
Reply Dr. Haris Deen on September 24, 2014 at 9:42 am. Dear David, I cannot give you authoritative responses to hypothetical questions. The methodology used for adjustment of items such as what you have mentioned depends on whether the contract is a lump sum contract or a remeasured contract. If the contract is a lump sum contract containing the items that you have mentioned there is no adjustment whether the quantity increases or decreases. YOU CANNOT INTRODUCE AN ELEMENT OF REMEASURE TO A LUMP SUM CONTRACT UNLESS THE CONTRACT SAYS SO. If the contract is measure and value contract then the decrease in an item is valued as an omission at the contract rate and similarly an increase in an item is also measured and added to the contract value at the contract rates.

The Lump Sum Construction Contract – What seems to be the problem? « Dr. Haris Deen entered into the contract he knew that there were provisional sums within the contract sum and having contracted to do so he will have difficulty succeeding in a refusal. Reply David C on November 13, 2014 at 5:06 pm. Dr Deen I am not sure that I agree with your response. If it is a provisional sum, it is by definition an amount allowed in the contract document, thus it constitutes part of the work to be carried out. If it is not in the contract, then the work constitutes a normal Variation. If the work covered by the provisional sum is not properly described or the Employer wishes to use the amount for work not described in the contract (both of which happen frequently), the Contractor could refuse to undertake the work if it is not required to complete the scope of work defined in the contract. I believe that it would be difficult for a Contractor to refuse to undertake work covered by a provisional sum based on expertise or facility given that most of provisional sum work is, in any event, undertaken by specialist subcontractors. Regards Reply Dr. Haris Deen on November 19, 2014 at 4:15 pm. Dear David, I don’t believe that you read my response fully, Also the question appeared to be hypothetical. Anyway, my considered opinion having taught quantity surveying and contract administration and being familiar with most conditions of contract, I can safely say that provisional sums are provided in a BOQ for a variety of reasons. I have also found some QS’s using all kinds of euphemism to put contingencies in as provisional sums. However, all contracts provide for dealing with provisional sums, that they can be deleted entirely from the contract sum or used in part or full as instructed by the Engineer. If the provisioanl summ is for specific specialist work, then the Employer will obtain quotations for such work giving an opportunity for the contractor also to submit a price. Some contractors who have the expertise in the relevant works submit a price, some obtain prices from sub contractors and others do not submit prices. If you had read my response fully you will realise that I also qualified my answer by stating that the contractor having been given the opportunity of knowing what he was pricing for including provisional sums in the tender might have difficulty in refusing to execute such work. But remember that the proviiosal sum has been included in the tender BOQ by the Employer and as I explained earlier it is only a provision for known or unknown work at the time of tender. Therefore, any court will support a contractor refusing to undertake work that he does not have the expertise or resources to execute and that he did not know at the time of tender what type of work is to be executed against such provisional sum. That is the reason that contracts define provisional sums in a manner of flexibility.

Dr. Deen I read your response correctly, perhaps you should read my response more carefully. The question was whether a contractor can refuse to carry out work covered by a provisional sum. The methods used to implement a PS and what you may or may not have taught students are not at issue. A PS is an amount allowed in the contract for work and thus the Contractor will know of its existence, additional work post contract signing is a Variation regardless of what semantics you may choose. In the event that the work is not described or described so inadequately that the Contractor cannot be expected to understand the nature of work included, the work covered by the PS would be part of the scope of the work and thus the Contractor could not refuse to undertake such.

Rick on October 20, 2014 at 6:06 pm. Hello, I will be grateful if you can give your opinion with regards to my current contractual issues on a Lumpsum contract project. Contractor is considering filing a Change for the “unforeseen” utilities which they said is not included in tender drawings. My argument is as “experienced” contractor they should have anticipated and this is determinable especially the area affected is a residential… an “unforeseen” utility might be like if you are in a middle of the desert and you found a telephone lines etc.. The only catch what I think reason the contractor is so eager to file for a Change is that there is something in the contract which it states that…Connection of houses related to existing utilities not shown on the Contract Drawings or Documents and unforeseen utilities that are not shown on the Contract Drawings, provided that the cost of these is reasonable, in the aggregate within US$ 38,457,000. Thanks in advance.
Reply Dr. Haris Deen on November 13, 2014 at 4:46 pm. Dear Rick, The mere fact that utilities found underground have not been shown on the drawings does not make them unforeseen. If the contractor is executing work in a green field area and he finds a live electric cable underground this is certrainly unforeseen and unforeseeable in any green field site. If the contractor was working in an are which was heavily bombed during WWII then he must certainly expect unexploded bombs underground irrespective of whether they are indicated on the drawing or not. Similarly if the contractor was working in an area which had buildings previous he must foresee such obstruction whether they are shown on any drawing or not.

Wahyu Nurhayanti on November 13, 2014 at 3:03 pm. Dear Dr. Deen, To begin with, I want to thank you for this interesting article. I have a querry related to variation in a lumpsum contract. I am administering a designbuild contract which using FIDIC yellow book and based on lumpsum contract price. The case is that the Employer has an obligation to provide freeissue material in the form of linepipe with specific diameter and wall thickness stated in the Employer’s Requirements. However, it turns out that the Employer cannot provide the linepipe with the determined specification. The actual freeissue materials are linepipes with the same diameter but lesser wall thickness. Since the reduction of wall thickness of the linepipes will affect the thickness of other materials provided by the contractor,such as elbow and hot bends, can the employer request a deduction in contract price to accommodate the reduction of the thickness of the elbows and hot bends procured by the contractor? To be honest, I doubt the the employer can deduct the contract price since based on the contract, the employer shall provide the freeissue materials under his own risks and costs. Therefore, should the employer failed to provide the freeissue materials in accordance with the original specification, such risks cannot be transferred to the contractor. However, it may still debatable since if what happen is the contrary then the contractor will pursue an additional cost for the specification change. Would you kindly give an insight regarding this problem? Thank you very much.

Do you think that the Employer any amount exceeding the allocated amount in the Cost Plan ? Our Client is opted to omit item from our scope , this item in the BOQ is 75 m2 whereas the drawings is 2000m2, then in your point of view the omitted amount should be 2000* unit price Or 75 * unit price In my point of view the ; the Client is not in a position to delate more than the allocated amount in the BOQ, since having this approach from the Client end , we will end up with minus Contract Value.

Dear Dr. Haris I have a lump sum contract for a core and shell construction project in ksa wherein the BOQ is part of the contract documents besides the drawings, the specifications, work scope, and the contract agreement; the contract agreement stipulates that all documents of the contract are complementary with each other; furthermore, the BOQ has a disclaimer item stating that “in case of conflict among the contract documents, the most stringent one will be binding and applicable”. The general conditions of the contract are copied from FIDIC and translated to Arabic and there are no special conditions considered for this contract. We, as the main contractor of the project, have undergone excessive number of change requests (104) during construction that have caused delays on the time for completion of the project. Now that I have briefed you about the project, I would appreciate your earliest response to the following case which we are up against with the client and consultant being on one side: The client has requested a replacement for an item in the BOQ, which has a quantity of 1457 m2 of 40×40 cm granite flooring in ground floor against only 450 m2 shown on contract drawings, with a different size of water jet pattern of marble and granite material for the same area and location; however, insisting on deleting the total amount corresponding to the quantity of the BOQ (1457 m2) and pay only 450 m2 with a new rate as a variation.

If there was no change then the Employer will have to pay the contractor the total price in the Lmmp Sum quoted for 1457 m2 against the quantity of 145m2 as he cannot introduce an element of remeasure in a lump sum conntract. The reverse is also true if the BOQ contained a quantity of 145 m2 instead of 1457m2 the Employer can insist the Contractor to execute the whole of the 1457 m2 at the lump sum price quoted for 145 m2.

Dear Mr Sweedan, I am sorry for the delay in replying as I had other pressing business to attend to. Coming to you question the correct way is to delete the whole of the BOQ quantity of 1475 m2 . If you delete the actual quantity of 450m2 then you will be introducing an element of remeasure to a Lump Sum contract which is not the intention. If on the other hand if you delete only 450m2 what happens to the 1025m2 left in the contract which you will not be executing? Surely you do not expect to get paid for work that you will not be executing? This is a Contractor’s risk that he should have taken into account when submitting his tender. That is why it is very important to check the BOQ in a Lump Sum Contract at the time of pricing a tender. I am sorry that I cannot be of any more assistance to you Reply Ghaleb Sweedan on May 21, 2015 at 2:09 pm. thank you Dr. Haris; but what if they have not introduced such change, we would have gotten the whole total price of the 1457 m2 as in the Contract BOQ even though the actual quantity that would be carried out as shown on contract drawings is 450 M2. wouldn’t you agree? awaiting your earliest response.

The Lump Sum Construction Contract – What seems to be the problem? « Dr. Haris Deen thanks and regards Ghaleb Sweedan
Ahmed Shehadeh on May 2, 2015 at 7:02 pm. Good day, I need your input in regard to the below case, the Employer has opted to Upgrade and change the Branded Apartment and Hotel balcony Tiling from Porcelain to Reconstituted Stone. However , and after deep study to this issue , the Contractor has reached and concluded that additional Cost is associated with such upgrade of balcony Tiling as instructed by the Employer. In contrary, the Cost Consultant and based on his initial assessment to our submitted Variation in this regard has advised that a Cost Saving for the Employer’s benefits is associated, disregarding that the Contractor will incur a certain loss by implementing the Cost Consultant way of measurements , which is in our point of view is not tenable, but in fact , will cause a direct damage to Contractor, since it is very strange toupgrade the Material type and then ask the Contractor to submit a Cost Saving. The Contractor understanding to the current case in hand, that the Maximum Omission ( deduction ) to be applied due to such upgrade for the balcony’s Tilling, is the mount allocated in the Cost Plan , which in fact, the Contractor has satisfied himself with, and reflects the same amount that we allowed for during the Tender process to execute this Works, and are not entitled to receive more money than the contract specifies for the same scope of works, irrespective to any inconsistencies in the qty’s. Typically, it is presumed that the allowed amounts / sums in the BOQ do form a term in our lump sum contract, and its position has relevant insofar in complementing the other documents form the Contract , where the Contractor will not be paid any additional payment if the quantities required to be executed are greater than stated in the bill of quantity & therefore implied that the reverse is also true – being that if the quantities stated in such a Cost Plan are greater than what is required to be executed the contractor will be entitled to receive the full payment against that item. Therefore, any changes in the item description ( change of Materials Sepc) will not allow the Engineer/ Cost Consultant for remeasuring the Contractor’s scope of Works, since the contract averted so , and the Contractor codifies that the maximum amount of deletion/deduction shall be the sum allowed in the Contract for carrying out this particular task. To this end , the Contractor has used below criteria to calculate the Cost Implications for the upgrade in the Balconies Tilling. 1. Tilling qty’s in the Cost Plan (Combination of Ceramic tiles with Saudi granite band including all necessary fixings, fittings, accessories and all related work) = 2083 M2 2. Unit Price for the same in the Cost Plan = 92.27 JOD/m2. 3. Total allocated lump sum amount for the same in the Cost Plan = 192,615 JOD item B4/9/2 —— Maximum amount of deletion. 4. Total Ceramic in drawings which altered to Stone = 2,520.66 M2.

The Lump Sum Construction Contract – What seems to be the problem? « Dr. Haris Deen 5. Unit Rate for Compac Stone as per Jordan Market and submitted by the Contractor is = 99.52 JOD/m2 6. Therefore , total Cost for Copmc Stone = 250,856 JOD. 7. Total Cost Impact = 250,856 – 192,615= 58,241 JOD. Whereas in fact , and as indicated in M/s NEA’s assessment total deduction is 231,876.570 JOD , whilst the total allocated amount in the Cost Plan for the same item is 192,615 JOD , noting that and as per my viewpoint no Contractual reference and clause can allow them to deduct and omit any additional amount beyond and above the allocated amount for the same item in the Cost Plan , where our Lump sum Contract is not subject to any remeasurement.

Mohamed Rizwan on May 10, 2015 at 9:35 am. Dear Sir, I’m facing a Problem in my Project it is a Lump sum Agreed Project. I need to make clear about the variation valuation on bellow conditions. 01. we have agreed to execute a work on a lump sum contract but in our BOQ the Actual Quantity is much more than the existing qyt. now the Engineer does not need that item and he has changed the detail therefore to which qty i need to give the deletion to the real qty or the BOQ qyt? 02. Same as above case the BOQ quantity is lesser than the Actual Quantity Engineer dont want us to do that in this case to which qty i need to give the omission to the agreed lumsum BOQ qty or to the real existing qty which is higher than the BOQ? could you please provide me the solutions based on FIDIC or any other conditions of contract.
Reply Wael on June 13, 2015 at 4:11 pm. Omitting an item is not related to the actual quantities. in fact , actual quantities comes from the remeasurement which contradict the lump sum requirements Reply

The Lump Sum Construction Contract – What seems to be the problem? « Dr. Haris Deen Sameh Afify on July 29, 2015 at 3:25 pm. Dear Sir, I have query regarding the value engineering in a lump sum contract and the BOQ is part of contract documents. we have special condition which allow the contractor to make a value engineering which stats the cost saving amount shall be shared between the client and contractor 80% to 20%. I want to know how to calculate the saving. weather based on the BOQ rate or the cost which is the (BOQ rate – contractor’s Proffit). Thanks
Reply Dr. Haris Deen on July 29, 2015 at 10:12 pm. Yes, use BOQ rates where applicable. The 80%/20% split includes overheads and profits as well Reply Sameh Afify on August 3, 2015 at 8:10 am. Thanks for the reply. your answer is logic. My case is that the contractor is claiming that the contract clause mentions “…,while the cost saving amount will be shared upon the basics of 80% for the Employer and 20% for the Contractor”. since the BOQ unit rate includes the (cost + proffit), therefore the sharing to calculated based on the cost only. thanks alot.

Sameh Afify on August 3, 2015 at 8:20 am. Dear Sir, Based on a lump sum contract with BOQ. there was one item mentioned in the tender drawings and BOQ, while during the tendering process it was cancelled by the designer and all the tenderer were officially informed through official circular. unfortunately this item was removed from IFC drawings but not removed from the BOQ, moreover the contractor priced this item and his tender was accepted. now during construction, the contractor is claiming to get paid of this item since the project is lumpsum, although he will not execute it as per IFC drawings. taking into consideration that as per the contract the client can omit or add 25% of the contract amount. Best regards,
Reply Dr. Haris Deen on August 3, 2015 at 11:30 am. Dear Sameh, The Contractor in your case is trying it on. I do not know the Conditions of Contract that you are using. However, all contracts provide for dealing with variations. Variations can be additions or omissions from the contract. In your case you have good grounds for omitting the item from the contract, since it is clearly an error to retain it as it was deleted during tender. Furthermore, how can the contractor claim for something that he is not executing? Even in a Lump Sum contract there are limits.

Dear Sir, In a LS design and build , yellow fidic, contract the scope of the contract change from open space design in a office building with a fitout design and the contractor was instructed to follow the fitout plans. Because the initial design was only a concept we cannot quantify exactly the mininus and pluses of the executed works and issue a variation order. Who to establish the addition works needed based on the conceprt design layouts, part of the ER.s? The contractor insists to do the open space design first and to compare with the fit out executed Please advice Thank you.
Reply Dr. Haris Deen on September 2, 2015 at 12:38 pm. Dear Paul, The structural works are not remeasurable as they are lump sum contract works. There are no omissions. The fit outs are clearly additional works and has to be measured and valued for payment. However, when you start executing the fit outs, if you have to make changes to the structural work that was executed under the ls contract, then you will delete only such works that are affected and add back any builders work that work be required to make good the affected part.

Eureka Mzungu on September 1, 2015 at 10:25 am. Dear Dr Deen I have read your article with keen interest and it is the situation in which I am that prompted me to come to this forum and I must say I have learnt I great deal. However please bear with me because I am going ask a question similar to what my colleagues have already asked but like you have said everything situation requires a particular response according to the type of contract in use. My question Dr Deen is: I am a Project Manager for a local company in Botswana. We are involved in a project with a lump sum contract with BOQ forming part of the contract. The contract involves the construction 1nr Single storey Classroom block, 4nr water borne toilets and 5nr LA2 Houses. We are using the FIDIC Red 1999 Edition as our conditions of contract. Any clauses relating to this situation have not been revised they are as they are in the FIDIC Red Book 1999. In the BOQ only the substructure items have been put as provisional quantities and have since been treated as such. Now the situation that we have is the Employer issued a variation order to change the specification of face bricks to be used from FBS face brick to FBX Face brick. The FBX face bricks were priced only under the construction of LA2 Houses at a rate of P590.00/m2 and the FBS

The Lump Sum Construction Contract – What seems to be the problem? « Dr. Haris Deen face brick was priced under the Classroom block and 4nr toilet blocks at the rate of P300.00/m2. When we submitted our variation claim we used the rate of P590.00 for the FBX face bricks in the Classrom block and the 4nr toilet blocks our basis being rate of a similar item under the same contract. However the Employer now is refusing to pay for this as the amounts have increased significantly. He has opted to remeasure the superstructure and applied the remeasured quantities. The remeasured quantities have decreased from 1864m2 to 854m2 clearly changing by more than 10%. This has significantly reduced the variation claim and we would like to contest it. 1.0 In your own understanding is the employer right to remeasure the superstructure which we feel it is part of the firm quantities where remeasurement is not supposed to be introduced? 2.0 And what is our remedy under FIDIC Conditions of Contract 1999 Edition. 3.0 Do we apply Clause 12.3(a) (i) Evaluation of Measured Works and submit a new rate besides the P590.00 as the quantities have changed by more that 10%? 4.0 What is you interpretation of this Clause in 3.0 above? 5.0 Do we have any case law that can support this scenario? 6.0 We feel the fair way of doing this is to omit 1864 x P300.000 =P559,200.00 and add 1864 x P590.00 =P1,099,760.00 and the difference P540,560.00 is the money due to us. Or can we revise our rate based on the new qty of 854m2? Your prompt response on the matter will be highly appreciated and will go a great deal in solving our case. Thank you Eureka Mzungu
Reply Eureka Mzungu on September 1, 2015 at 10:42 am. Dr Deen Can you please respond to my case. Thank you Eureka Reply Dr. Haris Deen on September 2, 2015 at 12:33 pm. Dear Eureka, You do not state whether the contract is a lump sum contract. However, by reading the explanation you have provided, it seems to be a lump sum contract, based on the bill of quantities being a contract document. Before answering your questions specifically, I would like to clarify the following: (a) You cannot introduce the element of remeasure in a lump sum contract. The Contractor takes all the risks. The BOQ is a document supplied by the Employer as prepared by a quantity surveyor on behalf of the employer. If there are mistakes in the BOQ – it can be both ways, the higher quantity as in your case (then the risk is the employer’s), on the other hand if the quantity is lower than required to execute the risk is the contractor’s. Please ask your employer whether he is prepared to remeasure where the quantity is lower to give the benefit to the contractor. I am sure that he will say no and take refuge in the fact that it is a lump sum contract nit subject to remeasure. (b) The contractor when pricing a contract does not have the opportunity to change any quantities, to do so would mean

The Lump Sum Construction Contract – What seems to be the problem? « Dr. Haris Deen submitting an alternative tender. That will also mean changing the conditions for one tenderer from others. Therefore, the tenderer prices the tender on the basis of ‘swings and roundabouts’ by which where he will lose in one item for quantity mistakes he will gain from another. Having this as the background, the answers to your questions are as follows: 1.0. No the superstructure works are not remeasurable. Only the provisional quantity items in the substructure are remeasurable. However, if there are provisional sums and provisional items included in the superstructure element, then only these are re measurable. HOWEVER, IF THE CONTRACT IS NOT A LUMP SUM CONTRACT AND FIDIC RED BOOK CLAUSE 12.1 IS RETAINED WITHOUT AMENDMENT, THEN ALL THE WORKS EXECUTED ARE TO BE MEASURED AND VALUED. 2.0 FIDIC 1999 edition Clause 56 (1) has similar conditions requiring the Engineer TO ASCERTIAN BY ADMEASUREMENY OR OTHER MEANS THE VALUE IN ACCORDANCE WITH THE CONTRACT OF WORK DONE OR OMITTED AS PROVIDED FOR UNDER CLAUSES 51 AND 58 (1). THIS REFERS ONLY TO VALUATION OF VARIATIONS AND NOT FOR CONTRACT WORKS. 3.0 If FIDIC Red book has been used without particular conditions and without stating that the contract is a lump sum contract at the time of tender, then Clause 12.3 (a) is applicable. 4.0. Please see my answer to item 1.0 above 5.0. The case law is only in respect of lump sum contracts and these are given in my article 6.0. The contractor will have a right to request a revaluation according to Clause 12 (a) (I) to (iv) if the changes are exceeding 25%. Having said all the above, I must advice you that as a project manager, you must act in a fair and reasonable manner. In my 52 years experience as a contracts administrator, I have always acted in a fair and reasonable manner to both sides. It is not in anybody’s interest to hurt the contractor or his cash flow. Similarly, it is not fair to support the contractor where it is unreasonable and will affect the employer. Good luck with your problem and let me know how you get on. Reply Eureka Mzungu on September 2, 2015 at 3:35 pm. Dr Deen Thank you for the response and it has been of help. I have written the Employer most of the content is based on the responses you have given here and of course with reference to the contract. The Employers QS is in agreement with our arguments. We are waiting for the response as he has to consult other Employer’s Project team members. Thank you for the insight. Eureka Reply
