LightTable

What LightTable does

LightTable is an AI-powered quality control platform built for developers and contractors to catch costly issues early in pre-construction work. It reviews construction documents for errors, omissions, and coordination issues before ground is broken, aiming to eliminate rework and inefficiency in construction. The platform combines intelligent software with expert oversight to provide a powerful coordination engine and a foundation for a full-stack preconstruction platform.

Products

• QA/QC reviewCatches coordination issues early across architectural, structural, MEP, and civil disciplines. Prioritizes issues by cost impact and allows side-by-side drawing comparison.
• Checklist reviewEnables checking every project against custom lessons learned.
• Ball in courtProvides clear issue ownership to prevent anything from falling through the cracks.
• Expert double checkOffers expert human validation on top of AI detection.
• Value engineeringIdentifies substitutions and design optimizations to reduce project costs without compromising quality or schedule. Provides specific recommendations with pros, cons, and downstream system impacts.
• Risk analysisAnalyzes GMP documents alongside drawings to identify financial or schedule exposure. Finds gaps between GMP and contract documents and connects contract risks to open QA/QC issues.
• Track changesCompares two versions of a drawing set page-by-page to identify every change, catching scope changes and helping keep bids current.
• VersioningTracks how issues evolve across project phases, calibrates findings as expectations change, tracks issue resolution, and shows trends over time.

AI approach

LightTable uses AI to review construction documents (drawings, specs, checklists) for errors, omissions, coordination issues, and constructability issues during pre-construction. The AI is trained on real-world building logic and prioritizes issues by cost impact. The platform also includes expert human validation on top of AI detection.
