Under the CPWD Delhi Analysis of Rates 2023 (Civil), item 19.2.4 — Providing and laying cement concrete 1:5:10 (1 cement : 5 coarse sand : 10 graded stone aggregate 40 mm nominal size) all-round S.W. pipes including bed concrete as per standard design : 250 mm diameter S.W. pipe — is derived from 1 priced inputs for 10 metre and works out to ₹1,590.55 per metre after water charges, GST, CPOH and cess. The full build-up is below.
- Area = W x W/2 + ½ x (3.14 x W² / 4)(3.14 x D² / 4)
- = W² x (0.5 + 3.14 / 8) - (3.14 x D² / 4)
- Where W = D + X
- D = 250 + 20 + 20 = 290 mm or 29.0 cm
- X = 300 mm as trench depth is less than
- 1200 mm
- W = 29 + 30 = 59
- Area= 59² x ( 0.5 + 3.14/ 8) - (3.14 x
- 29²/4)
- = 2447 sqcm = 0.2447 sqm. Say 0.244
