01 / MEASURE BEFORE YOU MULTIPLY
Plot area is not
a construction budget.
Imagine two quotations that both say “per sq ft”. One uses the plot area; another uses the total area of the proposed floors. Even before the material choices differ, the figures may be describing different work.
- Plot area
- The area of the land. A 20 × 50 ft rectangle measures 1,000 sq ft; that is not a statement about permitted coverage or the number of floors.
- Quoted construction area
- The area the contractor says the rate applies to. Ask for a floor-by-floor measurement and how stairs, balconies, voids and other elements are treated.
- Carpet or usable area
- A different basis for discussing space. Do not swap it into a construction-rate calculation without agreeing the measurement definition.
A useful request is: “Please show the area calculation attached to this quote.” Keep the drawing revision and the estimate together so changes can be traced.
02 / A LIKE-FOR-LIKE CONVERSATION
The cheapest line
may not be the same brief.
Ask both contractors to respond to the same list. “Standard materials” or “complete work” does not tell you enough to compare specifications.
| Clarify this | Ask for this in writing |
|---|---|
| Area & drawings | Measurement basis, floor areas and the drawing revision being priced. |
| Structure & design | Professional responsibilities, relevant specifications and which drawings or design fees are included. |
| Electrical & plumbing | Point counts, fittings, service scope and connection-related exclusions. |
| Finishes & joinery | Material specification, quantities or allowances, and what happens if selections change. |
| External & separate work | Boundary walls, external paving, drainage, interiors, authority-related items and other exclusions. |
| Payments & changes | Payment stages, taxes, provisional items, quote validity and written approval of variations. |
For interiors, compare the same rooms and quantities. A kitchen image or a “2BHK package” is not a substitute for dimensions, hardware and an installation scope.
03 / USE YOUR OWN NUMBERS
A base calculation.
Not a market-rate estimate.
Enter an area and rate from the same written quotation. This simply multiplies the two. It cannot price the land, determine a buildable area or fill in missing work.
04 / MAKE THE UNKNOWNS VISIBLE
A budget needs
decisions, not just totals.
List the items not selected yet. Ask whether each is an allowance, a provisional amount or excluded altogether. Record who supplies it, when a decision is needed and how a different selection changes the price.
Discuss payment stages and what evidence of progress supports each stage. If work changes, ask for the revised scope, price and time implications before accepting the variation. Keep a copy of the agreed version.
