In case of levelling operations and earth work, measurements are required to be recorded in level books in addition to Measurement Books. The level books should be numbered, accounted for and handled like Measurement Books. Before starting the earth work (S/S levels), original ground level should be recorded in the level book in the presence of contractor or his authorised representative and should be signed by him
and the Departmental Officer who records the levels. All the local mounds and depressions should be indicated clearly in the drawing and field level book and should be checked by site Engineer before levelling is started. Measurements of the levelling work shall be recorded by an official not less than E1. Levels may also be taken by a Jr. Engineer but these shall be verified/checked by an officer not less then E1 in presence of the contractor. Contour map shall be prepared before commencement of the work & after completion of the job. Also "L"section & cross section as per the spot levels shall be prepared & duly signed by the rep. of Powergrid & contractor. The"L" section,contour plan & the level book shall be sent to DHQ & Approval of Divisional Head shall be obtained.

of
Back to contents page The method of measurement for different types of piles is given in IS:1200 part (XXIII) latest edition. However, the following method should be adopted in the case of bored cast in situ, driven cast in situ and driven pre- cast piles. Bored Cast-in-situ piles: The steel cage to be lowered in the pile bore hole shall be measured accurately by a steel tape on the ground. After the cage is lowered and rested in the hole, the length of the cage above the cut-off level shall be measured separately with the help of levels. The difference between the total length of the steel cage and the latter length shall be the length of the pile below cut-off level and shall be (x-Y) units (Fig.-I, Sketch-I). Driven Cast - in - situ piles: The height of the shoe shall be measured in advance of its placement in position. The length of the casing pipe to be driven for a particular pile shall be measured with the help of steel tape accurately on the
ground. If more than a single piece of casing pipe is required to be driven into the hole, the same shall also be measured. After the casing has been driven to refusal as per specification, the length of the casing above the cut-off level shall be measured with the help of levels. The length of the pile below cut off level shall be calculated by deducting the later length from the total length of the casing pipe(s) plus the shoe height (Fig.-I, Sketch-II) and shall be (x+z-y) units. However in case the reinforcement cage is made by joining two or more no. of cages then the overlapping distances at the joints should not be considered. Driven pre-cast The length of the pre-cast pile shall be measured upto toe with the help of steel tape accurately on the ground. The length above cut off level shall be measured with the help of levels. The length of the pile below cut off level/shall be (x-y) units(Fig.-I, Sketch-III). (D)
Measurement of Steel Bars: Back to contents page Bar or any other type of reinforcement used, like hard drawn steel wire fabric etc. for reinforced concrete shall be measured by weight in Tonnes. The weight shall be arrived at by multiplying the actual or theoretical length measured along standard hooks, cranks, bends, authorised laps etc. whichever is less, by the sectional weights. Claims for payment for this item shall be submitted with supporting document giving the schedule of Bars with sketches. The sectional weight to be adopted shall be IS Sectional weight. Standard hooks, cranks, bends, authorised laps etc. shall be measured. Separator pieces between two or more layers of steel shall not be measured. No payment shall be made for lap welding or butt welding if permitted, supports, chairs, hangers, etc. of height 300 mm and less, required for keeping the steel in position unless otherwise specified in the contract. For supporting horizontal reinforcement at heights larger than 300 mm, support drawings shall be prepared by the Contractor and payment shall be made for the supports as approved by the Engineer-inCharge, or as actually placed, whichever is less, at the same rate as for reinforcement.
No extra payment shall be paid for modification of already embedded reinforcement, if required due to faulty fabrication or placement. Dowels neither shown in the drawings nor instructed by the Engineer-inCharge, but required for construction facilities and/or sequences, shall not be measured.

Section-Two Guidelines
----------------------------------------------------------------SECTION
TWO ----------------------------------------------------------------GUIDELINES Back to contents page
2.1
Guidelines for maintenance of MB/AB Back to contents page
2.1.1
The Measurement Book/Abstract Book must be looked upon as the most important record since it is the basis of all accounts of quantities, work done by daily labour, by the piece worker or contractor or of materials received, which have to be counted or measured. The description of the works must be such as to admit the easy identification and check. Before the book is brought into use, the pages should be examined and any serious defects such as tearing off or the substitution of pages brought to notice at once.
2.1.2
All entries in Measurement Book/Abstract Book should be made in ink/dot pen.
2.1.3
As all payments of works or supplies must be based on the quantities recorded in the Measurement Book, it is incumbent upon the person taking the measurement to record the quantities clearly and accurately. If the measurements are taken in connection with a running contract on which work has been previously measured. He is further responsible (1) that a reference to the last set of measurement is recorded (2) that if entries for job or contract have been completed the fact is recorded prominently just above his initials.
2.1.4
Entries should be recorded continuously in the Measurement Books/Abstract Book. No blank page may be left and no page torn out. Any page left blank inadvertently must be canceled by diagonal lines, the cancellation being attested. No, entry should be crossed, or effected so as to be legible. If a mistake is made, it should be corrected by crossing out the incorrect words or figures and rewriting in the words or figures and the correction thus made should be initialed and dated by the officer making it. When any measurements are cancelled, the cancellation must be supported by the dated initials of the officer ordering the cancellation or by a reference to his orders by the officer who made the measurements. In either case, the reason for cancellation should be recorded. A reliable record is the object to be aimed at as it may have to be produced as an evidence in court of law.
2.1.5
No lines may be left blank. The lines not required should be carefully crossed out in ink in order to prevent additional entries being made afterwards. The total carried forward from the previous page of a measurement book should be entered above the top line, similarly the total at the foot of each page should be entered below the bottom line.
2.1.6
Each Measurement Book should be provided with an index which should be posted upto date as measurements are recorded in the book.
2.1.7
The signature of the contractor or his agent should be obtained in measurement book after such set of measurements with the addition, I accept all measurements. In the case of illiterate men their thumb impression may be taken.
2.1.8
Construction Engineers are responsible for the correctness of the entries in Measurement Book.
2.1.9
Check-measurements should be noted in Measurement Books, the items actually check measured being distinguished by the initials of checking officer.
2.2.

Annexure- XV Back to contents page CALCULATION OF EARTH VOLUME FROM SPOT LEVELS
In this method, the field work consists in dividing the area into a number of squares, rectangles or triangles and measuring the levels of their corners before and after the construction. Thus, the depth of excavation or height of filling at every corner is known. Let us assume that the four corners of any one square of rectangle are at different elevations but lie in the same inclined plane. Assume that it is desired to grade down to a level surface a certain distance below the lowest corner. The earth to be moved shall be a right truncated prism, with vertical edges at a, b, c and d [Fig. a]. If ha, hb, hc and hd represent the depth of excavation of the four corners, the volume of the right truncated prism shall be given by V = {(ha +hb +hc +hd)/4} X A = average height x horizontal area of the rectangle. Similarly, let us consider 'the triangle abc of Fig. (b). If ha, hb and hc, are the depths of excavation of the three corners, the volume of the truncated triangular prism is given by

Fig. (b)
V={(ha+hb+hc)/3} X A =(average depth) x horizontal area of the triangle. Volume of a group of rectangles or squares having the same area.[Fig. (a)]
Let us now consider a group of rectangles 'of the same area arranged as shown in [Fig.(b)]. It shall be seen by inspection that some of
the heights are used once only, some heights are common to two rectangles (such as at b), some heights are common to three rectangles (such as at e), and some heights are common to four rectangles (such as at f). Thus, in Fig. each corner height shall be used as many times as there are rectangles joining at the corner (indicated on the figure by numbers) Let ?h1= the sum of the heights used once. ?h2 = the sum of the heights used twice. ?h3 = the sum of the heights used thrice. ?h4 = the sum of the heights used four times. A = horizontal area of the cross-section of one prism. Then, the total volume is given by V = A(1Sh1+2Sh2+3Sh3+4Sh4)/4 Volume of a group of triangles having equal area [Fig. (b)] If the ground is very much undulating, the area may be divided into a number of triangles having equal area. In this case, some corner heights shall be used once such as point 'a' of Fig.(b) , some twice (such as at d), six times (such as at f) , and seven times (such as at j). The maximum number of times a corner height can be used is eight. Thus, in Fig. (b), each corner height shall be used as many times as there are triangles joining at the corner (indicated in the figure by numbers) . Let ?h1 =the sum of the heights used once. ?h2 =the sum of the heights used twice. ?h3 =the sum of the heights used thrice. ......................................... ......................................... ?h8 = the sum of height used eight times. A = area of each triangle. The total volume of the group is given by V=A/3(l?h1+2?h2+3?h3+4?h4+5?h5+6?h6+7?h7+8?h8)
