  P.W.(Roads) Directorate Section : 3 Schedule of Rates : 2008-2009 Consumption of Materials  167 CONSUMPTION OF MATERIALS 3.1   Consumptions for Plastering, Brickworks, Concreting etc. Consumption of different materials of construction in the corresponding contract items of works shall be computed on the basis of the quantities shown in Table: 3-1 , subject to a variation of plus / minus five percent. Where, however, the circumstances of work so require, the Engineer-in-charge shall be competent to allow (for record reason) for a greater variation.  N.B. :- This statement is based on the following assumptions: (1)   That dry sand with necessary allowance for bulking is used. (2)   That the size of bricks shall be 9 ¾˝ x 4 ¾˝ x 2 ¾˝  . (3)   Volume of 1 bag (50 Kg) cement = 0.035 m 3   TABLE 3.1 – 1: QUANTITIES OF MATERIALS REQUIRED FOR PLASTERING, BRICKWORK, CONCRETING & OTHER ITEMS Sl.

Where, however, the circumstances of work so required, the Engineer-in-charge shall have the authority to allow (with recorded reasons)  for a greater variation. 2.   For open graded mixes, having no specific job mix formula, the quantities as shown in the following tables shall be applicable. In case of any design mix, the consumption shall be guided by the specific approved job mix formula and relevant provisions of “SPECIFICATIONS FOR ROAD AND BRIDGE WORKS” published by MoRTH (4 th  Revision). However, for estimating purposes, the following quantities may be considered for all cases.
