How to Read a BOQ: The 10-Minute Guide That Saves Homeowners Thousands
The single biggest mistake homeowners make when hiring a contractor: accepting a one-line quote. "Renovation works — RM80,000" tells you nothing. A Bill of Quantities (BOQ) tells you everything. Here's how to read one like a quantity surveyor.
The anatomy of a BOQ row
| Description | Qty | Unit | Rate (RM) | Amount (RM) |
|---|---|---|---|---|
| Porcelain floor tiles 600×600, laid on screed | 850 | ft² | 12.50 | 10,625 |
- Description — what work, what material, what spec. Vague = danger.
- Quantity — how much, measured from the plan (or site). This is what you verify.
- Unit — ft², m², nr (number), lot (lump sum), mth (months)
- Rate — price per unit including material + labour. This is what you compare.
- Amount — qty × rate. This is what you pay.
The 5 red flags in contractor quotes
- Too many "lot" items — "Electrical works: 1 lot — RM12,000" hides everything. Points should be counted (per-point wiring rates here).
- No quantities at all — you can't compare two quotes without them.
- Missing preliminaries & making-good — they'll appear later as "extras".
- Rates far below market — the classic path to mid-project renegotiation or corner-cutting.
- No stated exclusions — a good BOQ says what's NOT included (permit fees, utilities, appliances).

Wakkiro generates a complete BOQ with quantities, current market rates and the derivation behind every line ("Basis: measured from plan area…"). Use it as your benchmark before signing anything.

- Compare rates, not totals — Contractor A's tiling at RM12.50/ft² vs B's RM18/ft² is a real conversation; RM80k vs RM95k totals is not.
- Question quantities — if your floor is 800 ft² and the BOQ says 1,100 ft², ask why (wastage allowance is normal at 5–10%, not 35%).
- Ask for the same BOQ from all bidders — give every contractor the same item list to price. Now the comparison is honest.
- Use benchmarks — an independent estimate (like Wakkiro's) gives you a market reference for every line before you negotiate.
Glossary: terms you'll meet
- Prelims (preliminaries) — site setup, insurance, supervision. Normal: 8–12%.
- P.C. sum / provisional sum — placeholder budget for undecided items (e.g. "tiles: allow RM8/ft²"). Watch these — they're where budgets drift.
- Making-good — repairing surfaces disturbed by the works.
- Contingency — buffer for the unknown. 10% is standard; 15% for old-house A&A.
- OHP — contractor's overheads and profit, often ~10%.
