Preconstruction & Estimating
What is Preconstruction?
Preconstruction is everything a builder does before breaking ground: estimating, bidding, constructability review, value engineering, scheduling, and procurement planning. It is where most of a project's cost and risk gets locked in.
In practice
Precon teams live in drawings, spreadsheets, and bid packages — which is why it has become the hottest area for AI in construction: automated takeoff, drawing risk review, bid leveling, and schedule generation all target precon workflows.
