Question (8) On what the level of detail depend in schedule?

Answer The level of detail used on a certain project depends on several factors:1- Culture of the organization managing the project: The level of detail of the schedule you would be required to make will be that which the organization or team is used to using or comfortable to use 2- Project management maturity: The lower the maturity the more they tend to ask for more general or less detailed schedules. The higher the maturity they tend to ask or be open for more detailed sophisticated models which are more in tune with the project needs. Maturity is very closed related to the capacity of the team. Whether they have the tools, the knowledge, the expertise, in house or external. 3- Project needs: Project needs are different for the different phases of the project life. The conceptual, the bidding or budgeting, and the construction phase have all different needs. Also the size and complexity of the project determines the level of detailed of the schedules. And one more important factor is the time frame for the construction of the project. If the project needs to be executed in a very short period of time or can be executed in a very relaxed period of time, the needs will be different. 4- Team members’ requirements: At different levels of the hierarchy and at different functions of the organization, the level of detailed for the information (including the schedule) will be different. Not only because of their individual responsibilities, but also because of their individual preferences 5- Specification in the contract: When the specifications have difficult conditions, then the schedule need more detail 6- More control: To make the schedule easier in control tries to make the duration for activities less than 20 days 7- Risk level: higher risk level need more detail, lower risk level need less detail

Question (9) Why the project manager doesn’t listen to the planning engineers usually?

Answer If you ask any project manager about this issue and if he honest with you, He will tell you "I have more experience from the planner so I don't need any one to make planning for me", He is true about experience but he is totally wrong about planning because planner make long-term planning and can see the critical area in the project, the effective planner is mean reason for finished the project at time.

Question (10) What is the different between level 1, 2, 3 and 4?

 

 

Answer The different between level 1, 2, 3 and 4:Level 1 – Management (Summary) Schedule: This will be a single page (A4 or A3) bar chart schedule rolled up from the Level 2 schedule. It will show contract milestones, key milestones and summary bars based on the WBS to the agreed level of details. The schedule will reflect the critical path. Level 2 – Overall Contract Schedule: In bar chart format, will show the relationship between all the activities in major work areas. This will also cover important elements like mobilization, sub-subcontracts, LLIs, critical activities and high risk activities. At initial stage this schedule will set up the framework for detailed Level 3 schedules. During the updates this schedule will rollup the progress and the forecasts from the Level 3 schedule. Level 3 – Detailed Contract schedule: Will be a bar chart based on a Critical Path Method (CPM) network. The activities will be broken to the small level so that these can be clearly identified, measured, resourced and linked in ‘start-to-finish’ relationship. Start-to-start and finish-to-finish relations will be omitted (or kept to absolute minimum) to ensure meaningful time analysis. Level 4 – Detailed schedules and control documents: Requirement of the Level 4 schedules will be covered in the ITBs and will be finalized upon award of the contracts. These schedules identify each deliverable and show the schedule (plan, actual, forecast) for every step for completing the deliverable. The schedules provide the basis for day to day implementation of the work as well for progress calculation. Common Level 4 schedules are engineering document register, Procurement Log, Piling status, Equipment foundation status, Spool fabrication status, testing schedule etc.

Question (11) What’s recovery schedule? And who you can make it from A-Z?

Answer Recovery schedule is a revision of the Master Schedule updated on a certain data date, The Engineer requested the Contractor to submit this recovery to show how is he going to recover the incurred delays up to date There are couples of questions you have to answer your self before starting it:1- If you are on the side of the Contractor, do you think you are entitled of any EOT or you do admit that the delay is all caused by you as the Contractor, if the answer is "No" then go to Step 2, otherwise, do not submit a recovery schedule, first of all you have to get your EOT for the duration you

 

  think you’re entitled for, then you can submit a recovery schedule for the remaining delay caused by you (the Contractor I mean). Steps to make recovery schedule:1- Filter the longest current path (the path with the highest negative float), track the activities causing the delay and list the reasons and the ways it can be solved (increasing manpower, purchasing a new shutter system, air flight delivery, etc). 2- Discuss with your management the problem, and the options available to solve it, let the team decide what's the best thing to do, and apply the change to the schedule. 3- Update the schedule, and see if there is another critical path arising after you corrected the first path, and repeat the steps above. 4- If you reach at any point that the delay cannot be recovered, just report it to your management, and again let the team take the decision (extra cost or liquidate damages) it’s a nice team work so do it properly and you will get the results.

Question (14) How calculate budget man-hours?

Answer In order to calculate budget man-hour you must have the budget quantity for each activity, from that and through your standard man-hour you convert your quantity into man-hours, the total of those manhours will be your budget man-hours. This budget can be modified, depend to drawing revision you have every time to check your quantity, and before you finalize your baseline, you must check your new quantity.

Question (15) How can I change responsibility, area, step, and WBS for multiply activities in the same time?

Answer You can use 3 options: 1- Show columns of all activity codes and WBS that need to change then organize it by those group or filter it then change the first row and highlight to the last row that will require same code. Then right click and fill cell. Repeat the process on each code and each column. 2- Use Global change. 3- Use export/import function in excel.

Question (16) How can I importing actual quantity in the Primavera3 ?

 

 

Answer Exporting from Primavera (Activity ID, Activity Description, resources, Quantity at Completion, Quantity to Complete, Actual Quantity After exporting data, open the file extension will be (DBF) and put an equation in (Actual Quantity) column, the equation will be Actual Quantity = (Quantity at Completion) – (Quantity to Complete) Insert remaining quantity in (Quantity to Complete) column Importing the file to Primavera3

Question (17) How we can change calendar for 100 activities in one click?

Answer From global change put in (if statement) the specification for activities you want to change their calendars, put in (then statement) Data Item: put CAL (standard for calendar ID)/ Criteria: EQ / Data Item/Value: choose your calendar ID

Question (18) What are the different between WBS Vs Activity Code in Primavera

Answer WBS Code 1- Are needed to keep order in Portfolio of Jobs especially when activity code values are not shared. 2- Can be difficult or time consuming to reorganize. 3- Can be created from Activity Codes, this makes it easier to reorganize if this satisfies your needs. 4- Most software provide for a single WBS dictionary which makes very hard if not impossible for two users define their own based on their particular needs

Activity Code 1- Are easier to setup. 2- Meaning of each level is always constant while this is not necessarily so under other outlining methods. 3- Easier to reorganize the order of levels by simply moving the codes.
