First, what does the rate actually cover?
Some quotations are for the structure only: foundations, RCC frame, slabs and brickwork. Others include plaster, flooring, plumbing, electrical and paint. A turnkey rate should also include design, approvals coordination and handover. Comparing a structure-only rate with a turnkey rate is comparing two different products.
Ask every contractor the same question: which of these items are inside the rate, and which are extra?
Key Specifications & Factors
- Design, structural drawings and approvals
- Excavation, foundations and plinth
- RCC frame, slabs and masonry
- Plaster, waterproofing and flooring
- Plumbing, sanitary fittings and electrical
- Doors, windows, kitchen, paint and finishes
- External works: compound wall, paving, drainage
A low rate that leaves out finishes or approvals usually ends up costing more than a higher rate that includes them.
What moves the number most
Finish level is usually the biggest variable. Flooring, windows, bathroom fittings, kitchen and wardrobes can change the total more than the structure does. Agreeing a finish schedule - brand and grade for each item - is what turns a vague rate into a real price.
After finishes come the building itself and the ground under it. More floors, longer spans, basements and cantilevers need more steel and concrete. Soil conditions and the water table decide the foundation design, which is why a soil test should come before a final price.
Material prices also move. Steel and cement in particular change through the year, so a quotation should say how long its prices hold.
Key Specifications & Factors
- Finish level and the specific brands chosen
- Number of floors, spans and structural complexity
- Soil and foundation type
- Site access, levelling and filling
- Timing of material purchases
How to compare two quotations fairly
Put the quotations side by side against the same list of items and the same finish schedule. Where one leaves something out, add a realistic allowance for it before comparing totals.
Then look at how changes are handled. A contractor who prices variations in writing before doing them protects your budget; one who settles them at the end does not.
Key Specifications & Factors
- Same scope list and finish schedule for every quote
- Written list of exclusions
- Payment schedule tied to completed stages, not dates
- How long material prices are held
- How changes are priced and approved
The best quotation is the one with the fewest surprises left in it, not the lowest first number.
