How we build an estimate

See a Cost Estimate Come Together in 3D

Measured quantities are priced at agreed rates, trade by trade, then preliminaries, overheads & profit and contingency are added — so you can see exactly where the project cost sits.

  1. Quantities come first: the concrete and the steel frame are measured from the drawings, package by package.
  2. Roofing, cladding and glazing are measured off the plans and elevations, and services are allowed for against the floor area.
  3. Each quantity is priced at its agreed rate, built up from material, labour and plant, so every package becomes a cost.
  4. Ranked largest first, the packages show what drives the price — here services and cladding carry 72% of trade cost.
  5. Trade costs are totalled, then preliminaries, overheads & profit and contingency are priced as separate items.
  6. Everything builds up to the estimate total, checked as a cost per m² of gross floor area, with the assumptions stated.

FAQ

Common Questions

More answers on our FAQ page

Rates are agreed with you before pricing. We can use your own rates, supplier quotes you provide, or market-based rates appropriate to the project location. The rate source is stated in the assumptions, and currency and units are agreed at the start.

Yes. Early estimates are prepared from the information available, with assumptions clearly stated so they can be refined as the design develops.

No estimate can guarantee final cost. We provide a transparent, well-documented estimate so you can understand the basis of every figure.
