Under the CPWD Delhi Analysis of Rates 2023 (Civil), item 19.3.3 — Providing and laying cement concrete 1:5:10 (1 cement : 5 coarse sand : 10 graded stone aggregate 40 mm nominal size) up to haunches of S.W. pipes including bed concrete as per standard design : 200 mm diameter S.W. pipe — is derived from 1 priced inputs for 10 metre and works out to ₹873.50 per metre after water charges, GST, CPOH and cess. The full build-up is below.
- Area = WxD1 + 2x½xR Cot QxR [R²/2(3.14/2-Q)] - (3.14/2)R²
- = WD1 + R²(Cot Q) - R²(3.14/2 - Q) (3.14/2)R2
- = WD1 + R²(Cot Q - 3.14 + Q)
- Where Sin Q = [R/(W/2)] = 2R/W
- W = D + X ; X = 300 mm, D = 200+ 17 +
- 17 = 234 mm
- W = 234 + 300 = 534 mm
- D1 = Depth = 150 + (½ x 234) = 267 mm
- R = 117 mm
- Sin Q = (2x117)/534 = 0.4382 therefor
- Q= 26°0’
- Hence Tan Q = 0.4877
- Area = 534 x 267 + (117)² (Cot Q - 3.14
- + Q)
- = [142578 + 13689 (1/0.4877 - 180°+
- 26°0’)] sqmm
- = [142578 + 13689 (2.05 - 154°0’ x
- 3.14/180)] sqmm
- = [142578 + 13689 x (2.05-2.69)] sqmm
- = [142578 + 13689 x (-0.64)] sqmm
- = (142578 - 8760.96) sqmm
- = 133817.04 sqmm
- For 10 m length qty. of concrete reqd. =
- 0.134x10 = 1.34 cum
- Say 133817 sqmm or 0.134 sqm

Use this rate in a live estimate
This is the CPWD base analysis. A real estimate adjusts it for the project's inputs and the current cost index, then maps it to the tender's BOQ. Arched reads the tender, maps it to the applicable schedule, and flags where the numbers are exposed before submission.
