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 size | 225mm x 110mm x 65mm |
Sample 1m x 1m | a) 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 |
b) | Mortor |
Qty. of wet mortor | Qty. 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 mortor | Wet volume + 20% Bulkage factor = 0.044 cum + 0.009 cum = 0.053 cum per Sq.m |
Rate Analysis for Brick Bat Waterproofing:
Item No. | Item | Explaination | Quantity | Unit | Rate/unit | Amount |
A | Material | |||||
a | Bricks | 100 Sqm x 35 no | 3500 | No | 7 | 24500 |
b | Mortar | For 1 Sqm = 0.053 cum for 100 Sqm = 5.3 cum Therefore, 5.3/(Sum of proportion) Therefore,5.30 cum/(1+3) Therefore, Value for One (1) is 1.32 | ||||
Cement | 1.32 cum x 30 | 40 | cum | 280 | 11088 | |
(1cum = 30 bags) | ||||||
Crush Sand | 1.32 cum x 3 | 3.96 | cum | 990 | 3920.4 | |
Total of A | 39508.4 | |||||
B | Labour charges | 100 | sq-m | 280 | 28000 | |
C | Wastage @ 5% | 1975.42 | ||||
D | Scaffolding & tools @ 1% | 395.084 | ||||
E | Water & electricity including curing @ 2% | 790.168 | ||||
Total | 70669.072 | |||||
F | Add for profit & Overhead @15% | 10600.36 | ||||
Total rate | For 100sq-m | 81269.43 | ||||
Total rate | For 1sq-m | 812.7 |
great put up, very informative. I wonder why the opposite experts of this sector don’t understand this. You should continue your writing. I’m sure, you have a huge readers’ base already!
