What a construction estimator does
Construction estimators prepare the cost estimates and bids that decide which projects you win and whether they make money. They review drawings and specifications, perform quantity takeoffs, request and compare subcontractor and supplier pricing, and assemble bids under deadline. A careful estimator spots scope gaps before they become losses. A rushed or inexperienced one can win work you later regret taking on.
The role sits between the office and the field, so the best estimators understand construction methods as well as spreadsheets. Finch screens candidates for the project types and trades they have estimated, their software skills and how they check their own numbers. Whether you are a general contractor or a trade contractor, we look for someone who fits the way your company bids and builds.
