Under the CPWD Delhi Analysis of Rates 2023 (Civil), item 19.3.4 (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 : 250 mm diameter S.W. pipe) is derived from 1 priced inputs for 10 metre and works out to ₹1,016.90 per metre after water charges, GST, CPOH and cess. The full build-up is below.

NOTES
  • 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 = 250 + 20 +
  • 20 = 290 mm
  • W = 290 + 300 = 590 mm
  • D1 = Depth = 150 + (½ x 290) = 295 mm
  • R = 145 mm
  • Sin Q = (2x145)/590 = 0.49154
  • therefor Q = 29°26’
  • Hence Tan Q = 0.5635
  • Area = 590 x 295 + (145)² (Cot Q - 3.14 + Q)
  • = [174050 + 21025 (1/0.5635 - 180°+
  • 29°26’)] sqmm
  • = [174050 + 21025 (1.77 - 150°34’ x
  • 3.14/180)] sqmm
  • = [174050 + 21025 x (1.77-2.63)] sqmm
  • = [174050 + 21025 x (-0.86)] sqmm
  • = (174050 - 18081.5) sqmm
  • = 155968.5 sqmm
  • For 10 m length qty. of concrete reqd. =
  • 0.156x10 = 1.56 cum
  • Say 155968 sqmm or 0.156 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. We can do this for you: send the tender and we return a priced BOQ on the applicable schedule, with rate build-ups and an engineer's sign-off.
