Why a BOQ beats a lump-sum quote
Many contractors quote a single figure for grey structure or a complete house. It sounds simple, but two lump-sum quotes rarely cover the same work. One may include the boundary wall and water tanks; another may not. One may assume thinner slabs or lower-grade materials. Without a BOQ, it is hard to tell.
With a BOQ, every contractor prices the same list. Differences become visible item by item, and you can ask why one line is much higher or lower. During construction, the BOQ becomes the reference for measuring work done and checking interim bills.
- Compare contractors on the same scope
- Catch missing items before signing
- Track material deliveries against planned quantities
- Price changes clearly when you alter the design
What a house BOQ in Lahore usually includes
Grey structure items cover excavation, foundation, concrete for footings, columns, beams and slabs, sariya, brickwork, damp-proofing, plaster and roof waterproofing. Given Lahore's monsoon, waterproofing and roof treatment should be clear separate items, not buried inside other work.
Finishing items cover flooring, wall tiles, paint, doors, windows, kitchen and wardrobes, sanitary fittings, electrical fittings and false ceilings. Many owners now add backup power wiring, solar provision and roof insulation for summer heat. Listing these in the BOQ means contractors price them properly instead of treating them as extras later.
Keeping the BOQ accurate
A BOQ is only as good as the drawings behind it. If structural drawings are missing, steel and concrete quantities become estimates. If finishes are not chosen, the estimator uses assumptions. Ask the professional to list assumptions clearly, and update the BOQ if the design changes. Material prices move often, so the BOQ itself focuses on quantities; contractors or you can apply current market rates when pricing.
