Measurement of civil engineering works occupies a very important place in planning and execution of works, right from the stage of preparation of estimate to the final completion of works and settlement of payment of the works to the contractors.
There are some differences regarding the method of measurement among the State Government departments. But the method introduced by the Indian Standard (I.S.) is legal and basic document for removing ambiguities and settling all the disputes for making payment to the contractors.
Following points shall be noted while taking measurements.
1. Each item shall be fully described.
2. The measurement shall be taken in the order of sequence of length, breadth or width and height or depth.
3. Dimensions shall be measured to the nearest to 0.01 m.
4. Area shall be worked out to the nearest to 0.01 m2.
5. Cubic contents shall be worked out to the nearest to 0.01 m3.
6. The same work done under different conditions shall be measured separately stating the conditions, the lift and lead wherever possible.
