BOQ format
How to quote plumbing and sanitary work
How plumbing and sanitary work is split on an interior BOQ, and why who supplies the CP fittings changes who is responsible when one leaks.
The unit
Point (nos) for the rough-in, each fixture priced separately
Concealed work is counted as points — inlet, outlet, drainage. The visible sanitaryware and CP fittings are separate lines because they are usually chosen by the client after the walls are closed.
What the BOQ breaks into
| Line | Unit | Why it is its own line |
|---|---|---|
| Inlet points | nos | Hot and cold counted separately where both run. |
| Drainage points | nos | — |
| Concealed piping | rft | Where priced by length rather than by point. |
| Sanitaryware | nos | WC, basin, tub. Supply or install-only — say which. |
| CP fittings | nos | Taps, showers, health faucets. Most often client-supplied. |
| Water heater provision | nos | — |
| Chasing and making good | rft | Cutting the wall and closing it is civil work inside a plumbing line. |
The specs that decide the rate
- Pipe material and class
- CPVC, PPR or composite, and the pressure class. Concealed for the life of the building.
- Who supplies what
- Client-supplied fittings are normal and fine, but the BOQ must say so on the line — it decides who replaces a failed cartridge in year two.
- Concealed valve brand
- The part nobody sees and everybody regrets. A diverter body is not a place to save.
Client-supplied fittings with no line saying so
Most Indian interior jobs have the client buying CP fittings themselves. If the BOQ does not record that, the studio is assumed to have supplied them — and is asked to replace one at its own cost when it drips eighteen months later. A supply/install column on every fixture line settles it before it happens.
