LightTable
LightTable is a web-based drawing review service that applies machine-learning checks plus optional architect and engineer sign-off to construction plans, specs, and shop drawings so teams catch coordination and constructability problems before work hits the field.
LightTable asks project teams to upload PDF or raster-based drawing sets, specifications, and checklists, then returns prioritized findings tuned to common multi-trade coordination failures. Marketing copy targets developers and contractors who carry schedule and cost risk during preconstruction and want faster feedback than a purely manual peer-review cycle.
The vendor states that its models are trained on real-world building logic and continue to learn as more documents pass through the system, but it does not publish head-to-head accuracy tables on the homepage, so treat performance claims as directional until you run a controlled pilot on your own archives (LightTable marketing site, 2026).
An optional Expert Double Checks layer adds human architects and engineers who review outputs when teams need a licensed second opinion beyond automated flags. Unlimited users, commenting, and issue tracking are advertised to keep field, office, and consultant groups aligned around the same issue log.
Pricing is not listed publicly; the primary call to action is booking a demo, which suggests enterprise-style packaging common among venture-backed construction AI startups. Validate licensing, data residency, and file retention policies during procurement because drawing uploads may contain confidential project information.

Pros and cons
Pros
- Focuses on costly coordination mistakes rather than generic doc management
- Combines automation with optional human experts for higher-risk projects
- Positions unlimited users, which helps large project teams share one log
Cons
- No public price or trial terms on the homepage; expect sales-led onboarding
- Effectiveness depends on drawing quality and standards; garbage uploads still confuse any ML stack
- Competes with established peer-review marketplaces; you must compare SLAs and turnaround times

Frequently asked questions
What file types does LightTable accept?
Marketing describes uploading drawings and specs, which usually implies PDF-heavy workflows common in GC shops. Confirm native Revit or DWG connectors, if any, with the vendor before assuming live-model checking.
Is LightTable a replacement for BIM clash detection?
LightTable focuses on document-level coordination intelligence and human-readable issues. True 3D clash detection in Navisworks or ACC remains complementary; ask how LightTable fits before or after model coordination meetings.
Who is LightTable built for?
The homepage calls out developers and contractors, which typically means risk holders who need early certainty on design packages. Designers can use it, but the value story centers on downstream cost and schedule protection.
Does LightTable work on active jobsites?
The product is web-based, so teams can access it anywhere with credentials. Field use still depends on connectivity, security policies, and whether your owner allows drawing data in a third-party cloud.
How much does LightTable cost?
There is no public rate card. Budget for enterprise SaaS pricing tied to project count, document volume, or company-wide seats after you complete a demo and scope statement.
How does LightTable compare to traditional peer review?
Traditional peer review relies on manual reading; LightTable automates first-pass triage and adds optional experts. You still need QC plans that define who acts on each issue class and how findings tie into your submittal log.
