9. Rate Analysis for Brick Bat Waterproofing

The rate analysis of brick work is mainly depends on brick work rate. The Rate Analysis for brick bat waterproofing is mainly depend on the material used and the labour charges.

Item Details: Brick bat waterproofing treatment 100mm thick in CM 1:3 with smooth surface finish

Quantity Assumed: 100sq-m

Rate assumed,

Cement: 280Rs Per Bag

Sand: 990 Rs Per Cu-M

Brick: 7 Rs Per Unit

Labour Rate: 280 Rs Per sq-m

Material calculation factor for brick bat waterproofing:

a) Brick
Brick size225mm x 110mm x 65mm
Sample 1m x 1ma) Bricks in one direction with 15mm mortor joint = 1m/0.24 = 4.17nos
 b) Bricks in another direction with 15mm mortor joint = 1m/0.125 = 8 nos
Bricks per 1 Sq.m 4.17 no x 8 no = 35 no per Sq.m
Qty. of wet mortorQty. of whole mass – Qty. of bricks = Qty. of mortor = 0.10 cum – (35 no x 0.225 x 0.11 x 0.065) = 0.044cum
Dry vol of mortorWet volume + 20% Bulkage factor = 0.044 cum + 0.009 cum = 0.053 cum per Sq.m
