What Is the Difference Between a Quantity Surveyor and a Cost Estimator?
A cost estimator focuses primarily on producing a price for a project at the bidding stage. A quantity surveyor covers the full financial lifecycle of a construction project, from initial BOQ preparation and tender documentation through to value engineering, procurement support, and ongoing cost monitoring during construction.
Keystone Estimators provides both services under one roof. You get the depth of quantity surveying and the speed of professional estimating without having to work with two different firms.
