When comparing labour-only and materials-and-labour structural-shell quotes, do not start by dividing price by area. First align the included work and identify what you will pay outside each quote.
1. Record responsibility for each item
List reinforcement, concrete, formwork, blocks, equipment, pumps, transport, storage, tests and waste removal. For each, state responsibility and measurement. “Labour only” may describe different scopes; a written breakdown is essential.
2. Use the same area measurement method
Ask how stairs, tanks, walls, annexes, voids and special elements are measured. One quote may use total floor area while another uses itemised quantities. Request the calculation method instead of assuming both square-metre rates measure the same thing.
3. Compare specifications and assumptions
Link prices to identified drawing and specification revisions. If the soil report or design is incomplete, record it as an assumption affecting the estimate. A preliminary price should not promise to cover changes absent from the pricing documents.
4. Look beyond the total
Record payments and milestones, price validity, initial programme and delay responsibilities. Define change-request pricing before execution, material and work acceptance, records of observations and whether taxes and fees are clearly included.
A comparison example without assumed prices
One quote may include equipment and waste removal while another excludes them. A lower total does not necessarily mean a lower final cost. Add excluded items using actual quotes for the same project, then compare cost, scope and obligations together.
What should you send for a clearer quote?
Send the Tabuk project location, current drawings, floor count, available ground information and contract type. Add the questions and exclusions to resolve. This is more useful than requesting a square-metre rate without project specifications.
