Reinforcement of R.C.C. works measured in terms of per quintal.
The weight of bar per metre length is given by-
= 2.472 kg
For 1m² single brick flat soling (conventional size), the number of brick required is 32.
The woodworks should be measured nearest up to 0.002m or 2 mm.
Plastering is measured in terms of m².If,
(a) opening area < 0.5 m² (No deduction is applied)
(b) opening area is between 0.5 m² – 3m², then (single side deduction is applied)
(c) opening area > 3 m², then (double side deduction is applied)
Volume of tank = 1m^3≈ 1000 litres.
Hence, quantity of 1m × 1m × 1m inside dimension of water tank is 1000 litres.
S. No. Type of work Cost of construction (Rs.)
1 Petty work < 20,000
2 Minor work 20,000 – 1,00,000
3 Major work > 1,00,000
The contractor is required to deposit some amount with the department as a guarantee of the tender known as earnest money. It is about 2% of total cost of construction.
In long and short wall method, the length of long wall is centre to centre distance between the walls and half breadth of wall on each side. CPWD prefers long wall and short wall method because it has less chances of error.
Schedule of rates contains detailed description of all items of work including their quantities with current rates.
