BOQ Guides
BOQ Checklist for Residential Building Projects in Lagos
What a Bill of Quantities should cover for plumbing, sanitary ware, kitchens, doors and finishes on a Lagos residential project — and how to get it priced fast.
Quick answer
A residential BOQ should list every plumbing, sanitary, fitting, hot-water, kitchen, door and stone item with its size, type, finish and quantity, grouped by section or by room. Send it to us as a PDF, Excel or Word file, or a clear photo: we review the quantities, clarify specifications, prepare pricing, confirm availability and arrange delivery.
Key things to know
- Group items by section (plumbing, sanitary ware, doors…) or by room.
- Always state size, type and finish for every line.
- A clear photo of a handwritten list is fine.
- We deliver to sites across Lagos and arrange delivery to other states.
A BOQ (Bill of Quantities) is the list of materials and quantities for a building project. A good BOQ protects your budget: it lets suppliers price exactly what you need, helps you compare quotes fairly, and stops expensive surprises halfway through the build. This checklist covers the services and finishes sections that we see on residential projects across Lagos.
How to lay out your BOQ
For each line, include: item description, size or specification, finish or colour, unit (piece, length, set, square metre) and quantity. The clearer the description, the more accurate the price.
| Item | Specification | Finish | Unit | Qty |
|---|---|---|---|---|
| One-piece WC | S-trap, soft-close seat | White | Set | 6 |
| Basin mixer | Single lever, hot & cold | Matte black | Piece | 6 |
| PPR pipe | Size and pressure rating | — | Length | … |
1. Plumbing
- Supply pipes (PPR, PVC) by size, with fittings
- Waste and soil pipes by size, with fittings
- Valves: gate, ball, angle, stopcocks, float valves, non-return valves
- Pumping machine(s), borehole pump, tank connections
- Floor drains, traps, gutters, sewer flap valves
- Consumables: tangit gum, thread tape, clips
2. Sanitary ware
- WCs by type (one-piece, two-piece, wall-hung with hidden tank) and trap
- Wash hand basins by type; cabinets where specified
- Bath tubs, shower trays or shower cabins
- Urinals and hand dryers for commercial spaces
3. Bathroom fittings
- Basin mixers or taps, basin wastes
- Shower sets (exposed or hidden), hand showers
- Shattaf with valves
- Mirrors and accessories per bathroom
4. Hot water
- Water heaters by size and location
- Safety valves and hot water pipes
- Water filters and spare cartridges
5. Kitchen
- Kitchen sinks (type, bowls, drainer) and wastes
- Kitchen mixers and pot fillers
- Cooker hoods and built-in gas cookers
- Cabinet fittings
6. Doors
- Entrance doors (security / bulletproof, mother-and-son, with canopy) by opening size
- Room doors by opening size and finish
- Glass doors
7. Stone and surfaces
- Kitchen worktops and islands (area)
- Vanity tops
- Stair treads and risers
- Floors and feature walls
For estates and blocks of flats, standardise: the same WC, mixer, shower and door across all units. It simplifies the BOQ, the supply and the installation — and it keeps the finish consistent.
Who prepares a BOQ?
On larger projects, a quantity surveyor prepares the BOQ from the architect’s and engineer’s drawings. On smaller projects, the contractor or the plumber often prepares the services and finishes list. Either way, the owner should review the finishes — the WC types, tap finishes, door styles and stone — because those decide both the budget and the final look.
Example: one bathroom on a BOQ
- 1 no. one-piece WC, S-trap, with seat and flush fittings
- 1 no. standing wash hand basin with basin waste
- 1 no. single-lever basin mixer, hot and cold
- 1 no. rain shower set with hand shower
- 1 no. shattaf with two-way angle valve
- 1 no. floor drain with trap
- 1 no. 30-litre water heater with safety valve
- 1 no. mirror and 1 set of accessories
Copy this block for each bathroom and adjust — it makes pricing fast and accurate.
Common BOQ mistakes to avoid
- Leaving out valves, wastes and connectors — small items that stop work when missing.
- Not stating the WC trap type (S or P).
- Door sizes without the actual opening measurements.
- No allowance for cutting waste on marble and granite.
- Mixing finishes across bathrooms by accident.
