Under the CPWD Delhi Analysis of Rates 2023 (Civil), item 26.6A — Providing, erecting, laying and fixing in position in 3.5 to 4 mm thick bamboo mat corrugated sheet (BMCS) as per IS: 15476-2004 in roofing with self drilling screws along with EPDM washers complete or with galvanized iron J or L hooks 8mm dia G.I. plain and bitumen washers etc, all complete as per direction of Engineer-in-Charge — is derived from 10 priced inputs for 181.30sqm area and works out to ₹6,012.10 per sqm area after water charges, GST, CPOH and cess. The full build-up is below.
- Consider a sheet of 18mx9m (external dimension of plinth). Area of roof = 18.5x9.8m
- = 181.30 sqm.
- MATERIAL:
- Sheets used = 2x 19 nos (2.44m x 1.05m)
- & 4x19 nos (1.83mx 1.05m). Total area
- = (2x19x2.44x1.05)+(4x19x1.83x1.05) =
- 243.39sqm, Add wastage @ 3% = 7.30
- sqm, Total area = 250.69 sqm.
- Weight of sheets, For 2.44mx1.05m sheet
- size, 12kg/Nos x 38 nos = 456 kgs, For
- 1.83m x 1.05m sheet size, 9kgs/Nos x 76
- Nos = 684 kgs. Total weight of sheet =
- 456+684 = 1140 kgs = 1.14 tonne
