CHART FOR CONSUMPTION OF MATERIALS
Consumption of different materials of construction in the corresponding contract items of work shall be computed on the basis of the quantities shown in this table subject to a variation of plus/minus 5% (five percent). Where, however, the circumstances of work so required, the Engineer-in-Charge shall be competent to allow (for recorded reasons) for greater variation.
This will apply not to items as per BIS specification (or its equivalent) but also to those as per IRC specification. In case of any variation, requirement as per BIS or IRC specification is to be followed with due approval of the Engineer-in-Charge.
N.B. : This Table is based on the following consideration :
The dry sand with necessary allowance for bulking is used.
The size of bricks used is (250 mm × 125mm × 75mm)
Modular Bricks (190 mm × 90 mm × 90 mm) = 50000 Nos. per 100 Cum. & 4951 Nos. per 100 Sq.m.
Weight of 1 Cum. of cement = 1.44 M. Ton.
