2023AI-powered construction drawing review platform that prevents city comments, RFIs, and change orders.
Buildcheck is an AI drawing-review platform for pre-construction. Users upload architectural, structural, civil and MEP drawings plus specifications; proprietary computer-vision models run hundreds of automated checks for errors, omissions and cross-discipline coordination conflicts, returning severity-ranked findings annotated back onto the sheets.
The platform has grown from a check engine into a collaboration suite: unlimited-user review workspaces plus four Series-A-funded extensions — Custom Checks (a firm's own QA/QC playbook parsed into review agents), Diffs (revision-to-revision change detection), and Code Reviews and Value Engineering modules, the latter two in beta in the U.S. and Canada.
The wedge is the roughly $200 billion in annual waste from design errors inside a $13 trillion construction industry, with about 20 percent of that spend in pre-construction 'soft costs' — reviews, coordination, estimating — that the company says AI can take over. Two-thirds of reviewed projects still carry life-safety drawing comments, per the founder's own dataset.
Adoption signals are strengthening: Buildcheck passed 110 paying customers and grew 4x in a year, DPR's corporate venture arm co-invested in its Series A, and EllisDon selected it in its 2025 ConTech Accelerator — evidence that major builders are institutionalizing automated design QA rather than treating it as an experiment.
Reported outcomes anchor the pitch: 10-35x claimed ROI, 50-percent-plus more meaningful comments than manual review, 150,000-plus drawings and $3B-plus project value processed, and 110-plus paying customers including DPR, EllisDon, Power Construction, IMC and AvalonBay within roughly three years of founding.
Technically, the company says its models are custom-built with multiple patents and Stanford-trained researchers, paired with human industry experts who validate outputs; it holds an EllisDon 2025 ConTech Accelerator win and a Cemex 2025 competition placement that double as enterprise-channel credibility.
Access is sales-gated: a competitor comparison characterizes Buildcheck as a quote-led enterprise motion while rivals push self-serve plan-checking, which lengthens the trial path for smaller teams. The two newest modules — Code Reviews and Value Engineering — remain in beta and limited to the U.S. and Canada, so the full platform is not yet generally available.
As a roughly 35-person company founded at Stanford in 2023, it competes against entrenched preconstruction software incumbents with far larger distribution, and its human-in-the-loop validation model adds operational cost per reviewed project that pure-software rivals do not carry.
Pricing is not published; the site routes every visitor through 'schedule a call' / demo funnels and case-study gates, consistent with per-project, seat-unlimited enterprise contracts sold to owners, GCs and design firms. Value selling is explicit: the homepage leads with 10-35x ROI and dollar-and-days saved ($221K/2 days Fitzrovia, $541K/27 days Primex), implying pricing anchored to prevented change-order spend rather than software seats.
Intake options — upload to the web app or simply send drawings — plus custom-agent extensions on its own QA/QC playbooks point toward tiered platform subscriptions with professional-services attach for playbook configuration.
