ANALYSIS
THE RATE OF FOLLOWING ITEMS OF WORKS
BRICK WORK IN CEMENT MORTER ( 1 : 6) :----YOU MAY ASSUME CEMENT – Rs 8100/MT , BRICK Rs 8500/%0NUMBERS ,SAND(coarse)-Rs 1150/M3 , SAND ((med) Rs 950/M3 ,HEAD MASON -326/DAY,ORDINARY MASIN -296/DAY , MAZDOOR-245/DAY.
Consider 10 cum volume of
brickwork.
Size of one brick with mortar =
( 200 * 100 * 100 ) mm3
No
of bricks = 10/(0.2*0.1*0.1) = 5000 nos.
Size
of one brick without mortar =(190*90*90 ) mm3
Volume
of mortar =10 – (5000*0.19*0.09*.009) =2.305m3
Due
to filling and wastage , the quantity is to be increased by 15%
Volume
of the wet mortar =(2.305*1.15) = 2.64m3
When
dry , this quantity to be increased by 33%
Hence
, volume of dry mortar =(2.64*133) =3.51 m3
Volume
of cement =3.51/7 =.50 Cum = 0.72 T
Volume
of sand = 3.51*6/7 =3.0 Cum
Considering 70 % coarse sand & 30% medium sand
Coarse
sand =2.1 Cum
Med.
Sand = 0.9 cum
