Rate Analysis for center line Method
Rate Analysis for Brick work.
Total Volume of Brick work = 11.643 + 9.315 + 6.986 + 54.337 = 82.281m3
Deducction of mortor:
Volume of mortor = 25/100*82.281 = 20.57m3
Net Brick Work= Total Volume of Brick Work - Volume of mortor = 82.281 - 20.57 = 61.71m3
No. of Bricks = 500/1cum*61.71 = 30855 bricks
Let me include 10% of wastage of bricks:
10% wastage = 10/100*30855 = 3086 bricks
Net Number of Bricks = 30855 + 3086 = 33941 bricks
Now calculate cement and sand:
Volume of wet mortor = 20.57m3
Volume of dry mortor = 20.57*1.27 = 26.1239m3
Ratio of mortor = 1:3
Sum of ratio = 1 + 3 = 4
Volume of Cement = 1/4*26.1239 = 6.531m3
Volume of 1 bag of cement in cum = 0.036m3
No. of bags of cement = 6.531/0.036 = 181.416 say 182 bags
Volume of sand = 3/4*26.1239 = 19.592cum
Bricks = 33941 bricks
Cement = 182 bags
Sand = 19.592cum
Rate Analysis for concrete:
Concrete for PCC:
Volume of wet concrete = 10.867cum
Volume of dry concrete = 10.867*1.54 = 16.7351cum
Ratio of concrete = 1:3:6
Sum of ratio = 1 + 3 +6 = 10
Voulume of cement = 1/10*16.7351 = 1.67351cum
Volume of 1 bag of cement = 0.036cum
No. of bags of cement = 1.67351/0.036 = 46.486 say 47 bags
Voulume of sand = 3/10*16.7351 = 5.0205cum
Volume of Bajri = 6/10*16.7351 = 10.0410cum
Bags of cement = 47 bags
Volume of sand = 50205cum
Volume of Bajri = 10.0410cum
Concrete for DPC:
Wet volume of concrete = 0.7405cum
Dry volume of concrete = 0.7406*1.54 = 1.1403cum
Ratio of concrete = 1:2:4
Sum of ratio = 1 + 2 + 4 = 7
Volume of cement = 1/7*1.1403 = 0.1630cum
No of bags of cement = 0.1630/0.036 = 4.525 say 5 bags
Volume of sand = 2/7*1.1403 = 0.3258cum
Volume of Bajri = 4/7*1.1403 = 0.6516cum
Bags of cement = 5 bags
Volume of sand = 0.3258cum
Volume of Bajri = 0.6516cum
Rate Analysis for Palster:
Palster for outside walls:
Wet volume of mortor = 330.48*0.025 = 8.262cum
Dry volume of mortor = 8.262*1.27 = 10.492cum
Ratio of mortor = 1:3
Sum of ratio = 1 + 3 = 4
Volume of cement = 1/4*8.262 = 2.0655cum
No of bags of cement = 2.0655/0.036 = 57.375 say 58 bags
Volume of sand = 3/4*8.262 = 6.1965cum
Bags of cement = 58 bags
Volume of sand = 6.1965cum
Palster for inside walls:
Wet volume of mortor = 270*0.025 = 6.75cum
Dry volume of mortor = 6.75*1.27 = 8.5725cum
Ratio of mortor = 1:6
Sum of ratio = 1 + 6 = 7
Volume of cement = 1/7*8.5725 = 1.2246cum
No of bags of cement = 1.2246/0.036 = 34.572 say 35 bags
Volume of sand = 6/7*8.5725 = 7.3478cum
Bags of cement = 35 bags
Volume of sand = 7.3478cum
