What changes

  1. AI software does the takeoff from the plans, and a person checks it

  2. Value shifts from counting to analyzing risk and knowing the market

  3. Owners and general contractors expect estimates faster, and in several versions

AI drafts, the person decides

How the work splits here: AI prepares a draft, the person checks it and makes the call.

AI makes the draft

What AI does

  • Quantity takeoff from PDF plans in specialized software
  • A re-price of the estimate when materials or the design change
  • A side-by-side comparison of two estimates, with the differences flagged
  • An estimate narrative and a cover letter to the owner
You check itRead it, check the facts, fix it. Without this check the draft goes nowhere.
You decide and stay responsible

What stays with the person

  • Checking the quantities, and knowing what isn't on the plans
  • Current supplier prices and knowledge of the local market
  • Responsibility for the bottom-line number
  • Defending the estimate to the owner and in bid reviews
