Category: Quantities & pricing
Prepared by Eng. Ahmed Fathy, Projects Manager ·
Definition
The engineer's estimate is the expected project cost prepared by the consultant or owner before tender, on the same items as the BOQ.
Why it matters on a project
It is used to assess bids: one far below the estimate may be unsustainable, one far above needs negotiation.
Common mistake
Building the estimate from an old project's rates without updating current material prices.
Frequently asked questions
Is the engineer's estimate shared with bidders?
Usually not; the owner uses it internally to evaluate bids.
How far can a bid be from the estimate?
There is no fixed figure, but a large gap either way calls for a check of the rate build-up.
