Rate of Sampling of Concrete. The rate of the sampling depends on the quantity of the concrete to be poured in a particular concrete. For smaller concrete, the sampling rate is higher compared with large volume concrete. The following table extracted from BS 5328: Part 1 indicates the rates to be considered in the sampling of concrete.

Rate analysis for 1m2 of brickwork masonry. For calculation rate per sq m of brickwork, We have brickwork volume = 1m3 and width of brick with mortar = 0.1m, then area of brickwork = 1/0.1 = 10m2. 10m2 brickwork cost = INR 7384, so rate and cost per sq meter of brickwork = 7384/10= 738.4 = INR 740. Rate per square metre for brickwork is INR 740.
