Lumen Bid keeps the estimator in the loop
An AI-assisted construction estimating tool that reads electrical drawings, counts devices, builds a priced bill of materials, and produces a bid for human review.
Field notes
The workflow separates counted marks from derived assemblies, then carries the result into a bill of materials containing part numbers and labor hours. The public sample is a five-sheet Harbor Street Studio job covering lighting and power, with fixtures, receptacles, switches, and specials available for review. The page also says edits survive reruns and that missing fixture quotes remain marked UNKNOWN rather than silently turning into zero-dollar prices.
