About

LightTable is an AI-driven peer review platform for construction and real estate development documents that automates the identification of errors, omissions, coordination issues, and compliance gaps before construction begins. The system ingests architectural drawings, engineering specifications, and related PDFs, and within 10–45 minutes delivers a prioritized list of redlines and flagged issues across multiple disciplines, including constructability, MEP, accessibility, and fire & life safety. Its AI layers domain knowledge on top of computer vision and language models to interpret relationships between drawings and specifications, detect conflicts and gaps, and drive expert-in-the-loop validation workflows. LightTable claims to surface up to four times more issues than traditional peer reviews and reduce coordination mistakes by up to 70%.

About

PreConstruct AI is a web-based construction takeoff and estimating application for subcontractors bidding interior finishes, concrete, and wood framing work from PDF drawing sets. It reads drawing scales and uses plan notes, schedules, and partition legends to help identify and measure walls, ceilings, and concrete quantities. AI-assisted wall suggestions are in beta and are reviewed, approved, or adjusted by the estimator. Approved quantities become material lists for items such as studs, board, insulation, tape, compound, paint, concrete, and rebar, with calculations and drawing-sheet references. Estimators can apply their own material prices, create proposal PDFs, and export data to Excel or CSV. Projects can use imperial units, metric units, or both. The application supports estimating workflows; estimators review measurements and quantities before submitting a bid.
