Rate analysis: one metric ton reinforcement
Short answer
Rate per metric ton of reinforcement is NPR 169,050, including 1,030 kg steel (3% wastage), 8 kg binding wire, 12 skilled and 12 unskilled man-days, plus 15% overhead and 10% profit.
Prepare the analysis of rates for one metric ton of reinforcement. Labor norms per MT: skilled 12 no/m³/day, unskilled 12 no/m³/day. Assume suitable rates.
The rate covers supplying, cutting, bending, placing and tying the steel bars as per drawing and bar-bending schedule, per metric tonne (MT). Rates are assumed: steel (Fe 500D) NPR 100/kg, binding wire NPR 130/kg, skilled labour NPR 1,500/day, unskilled NPR 1,100/day, overhead 15%, profit 10%. The labour norms are read as 12 skilled and 12 unskilled man-days per MT, as given.
Quantities per MT
- Steel kg plus 3% for cutting waste and laps kg
- Binding wire kg per MT (DUDBC-type norm)
- Skilled labour days; unskilled labour days
Analysis
| Item | Qty | Unit | Rate (NPR) | Amount (NPR) |
|---|---|---|---|---|
| Reinforcement steel (1,000 kg + 3% cutting and lap wastage) | 1,030 | kg | 100.00 | 103,000.00 |
| Binding wire (annealed 16 gauge) | 8 | kg | 130.00 | 1,040.00 |
| Skilled labour (bar bender) | 12 | day | 1,500.00 | 18,000.00 |
| Unskilled labour | 12 | day | 1,100.00 | 13,200.00 |
| Direct cost | 135,240.00 | |||
| Contractor's overhead @ 15% | 20,286.00 | |||
| Contractor's profit @ 10% | 13,524.00 | |||
| Total (rate per MT) | 169,050.00 |
Rate = NPR 169,050.00 per MT (about NPR 169.05 per kg).
If the contract pays only for the steel in the drawing (as per bar-bending schedule), the wastage allowance is not paid separately but is included in the rate as above.
