Outsource Construction Quantity Takeoff Services for AI-Led Preconstruction Estimation

Reduce estimation time and eliminate errors with construction quantity takeoff services powered by AI-Assisted CAD/BIM for auto-counting, cost mapping, and revision management.

Chief estimators and preconstruction managers across the US and Europe rely on our construction quantity takeoff services to get accurate cost estimates that protect project margins. With 25+ years of experience, we have a team of estimators who specialize across commercial and residential scopes.

Our teams leverage AI-assisted on-screen takeoff tools, including automated count and length detection in platforms such as PlanSwift and Bluebeam Revu. This approach accelerates first-pass measurement without compromising the judgment that goes into the final number. Estimators review and validate every figure before it leaves our desk. What you receive is the same rigorous takeoff you expect, completed in less time and at a cost that makes outsourcing the obvious choice.
