AI Quantity Takeoffs

Quantity takeoffs are where most estimating time goes, and where most bid errors start. These guides work trade by trade — drywall, ceilings and partitions, HVAC duct, electrical, fire protection, glazing, masonry, windows and doors, roofing, flooring, and chilled-water piping — covering how to measure counts, lengths, areas and fittings directly from PDF drawings instead of a spreadsheet and a scale ruler. You’ll also find buyer’s-guide comparisons of automated takeoff software and honest notes on what AI takeoff tools can and can’t do reliably on their own, so a machine-generated takeoff gets QA’d properly before it goes into a bid.
