MODES OF MEASUREMENTS

a) Supply and/or Carriage of Stone or laterite boulder 50Kg. and above size           : 1/6th (one sixth) To be deducted as voids from gross measurement of stack
b) Supply and/or Carriage of stone or Laterite boulder below 50Kg. size.                          : 1/7th (one seventh) Do Do
c) Supply and/or carriage of shingles & Brick or Jhama ballast, stone ballast & chips.        1/13th (one thirteenth) Do Do
d) Supply and/or Carriage of earth, Rubbish, Cinder, lime, surki, Moorum.     1/10th (one tenth) Do Do
e)   Supply and/or Carriage of Jhama bats or.       : brick bats 1/7th (one seventh) Do Do
f)   Sand (after necessary deduction of Bulking), steam coal or slacked coal.     1/18th (one eighteenth) Do Do

The specifications for all other items and supply of materials shall comply to printed specification of I. & W. D. and any materials not covered there shall comply with that of P.W.D. and the Indian Standard specification and any work not covered there shall be carried out as per best practice adopted in this country according to the direction and satisfaction of the Engineer-in charge.

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.
