| Cement, sand, rawl plugs, screws, white cement (lump) | 1 | LS | 400.00 | 400.00 |
| Plumber (skilled) | 1.0 | day | 1,500.00 | 1,500.00 |
| Mason (skilled) | 0.25 | day | 1,500.00 | 375.00 |
| Helper (unskilled) | 0.75 | day | 1,100.00 | 825.00 |
| Direct cost | 15,850.00 | |||
| Contractor's overhead @ 15% | 2,377.50 | |||
| Contractor's profit @ 10% | 1,585.00 | |||
| Total (rate per no) | 19,812.50 |
Rate = NPR 19,812.50 per number (direct cost NPR 15,850.00).
Quantities and rates change with the quality of the fittings; the labour part (plumber 1 day, mason 0.25 day, helper 0.75 day) follows normal DUDBC-type norms for sanitary fixing.
