Pricing: Not public (seed-stage, launched July 2026)
Glazing: Medium
MVP: Sign up for early access. Feed in PGC's capabilities (curtain wall, storefront, glass & aluminum) and see what projects surface in your region over a 2-week trial.
What it does: Deploys AI agents that perform quality control on technical documents and drawings for construction design engineering. Agents learn your firm's standards, apply the right building codes, and review drawing sets across both PDF drawings and native Revit models. YC S26.
Legacy alt: Manual QA/QC by senior engineers, peer review checklists, third-party plan review services
Differentiator: AI agents that learn YOUR standards and apply building codes automatically. Works across PDF and native Revit. Already used by 8 leading AEC firms.

What it does: The Open Design Alliance (ODA) is exposing its CAD-format SDKs to AI agents through self-hosted MCP servers. AI agents can read, write, and manipulate native DWG, DGN, and IFC files directly — opening up CAD/BIM data to the AI agent ecosystem at scale.
Legacy alt: Manual CAD data extraction, custom scripting with ODA SDKs, proprietary API integrations
Differentiator: First time ODA's industry-standard CAD/BIM SDKs are exposed via MCP for AI agents. Self-hosted (data stays private). Enables AI agents to work directly with native CAD files.
Pricing: Free for ODA members (membership required for SDK access; MCP servers are self-hosted)
Glazing: Medium
MVP: If PGC has ODA membership, spin up the MCP server and connect an AI agent to read a curtain wall DWG. Test: can the agent extract glass panel counts, frame lengths, and anchor points?
What it does: Open-source 2D & 3D structural analysis running entirely in the browser using the Direct Stiffness Method. No installation, no license server, no Windows requirement. Real-time solving with a visual interface. MIT licensed.

Differentiator: Browser-native, free, open-source. No installation at all — open stabileo.com and start. Direct Stiffness Method with real-time solving.
Pricing: Free (MIT open-source)
Glazing: Low
MVP: Model a simple curtain wall mullion span. Apply wind load and check deflection. Compare results against your current structural analysis tool.
What it does: AI takeoff platform that works across multiple trades — structural, architectural, MEP, and façades. Automatically identifies and measures quantities from construction drawings. Integrates with Procore and ConWize. Exports directly to estimation software or spreadsheets.
Legacy alt: On-Screen Takeoff, PlanSwift, Bluebeam — all require manual measurement per trade
Differentiator: Cross-trade capability — one platform handles structural, architectural, MEP, and façade takeoffs. Procore integration. Direct export to estimation software.
Pricing: Not public (likely $150-300/user/month based on comparable tools)
Glazing: High
MVP: Upload a curtain wall elevation PDF with surrounding structural and architectural context. Let AI measure glass area, frame lengths, and anchor points. Compare against manual takeoff.
What it does: Analyzes PDF construction plans across architectural, structural, and MEP disciplines. Detects clashes and inconsistencies, then auto-generates draft RFIs. Now production-ready with Procore and Autodesk integration. YC S26.
Legacy alt: Manual clash detection in Navisworks + manual RFI drafting
Differentiator: Auto-generates draft RFIs from detected clashes — not just flagging issues but creating the documentation to resolve them. Now production-ready.
Pricing: Not public (YC S26, seed-stage, now production)
Glazing: High
MVP: Upload a set of architectural + structural + MEP drawings for a current glazing project. Compare detected clashes against what your team found manually.
What it does: Free, open-source construction ERP now at v8.6 with vector DWG/DXF takeoff. 71 modules covering BOQ, PDF/CAD/BIM takeoff, AI cost matching, tendering, change orders, risk register, and document management. 42 regional catalogues, 21 languages. AGPL-3.0.
Legacy alt: Sage 100 Contractor ($3K+/yr), Viewpoint ($10K+/yr), Jonas ($5K+/yr)
Differentiator: Completely free and self-hosted. Vector DWG/DXF takeoff in v8.6. No per-user licensing. Active community development.
Pricing: Free (AGPL-3.0, self-hosted)
Glazing: High
MVP: pip install openconstructionerp on a test server. Import a past PGC project (BOQ, drawings, supplier list). Run through the estimating → procurement → change order workflow.
What it does: AI-driven plan analysis that automatically identifies and measures project areas from construction drawings. Reduces manual takeoff time by 70-90%. Independently validated accuracy. Instant report generation.
Legacy alt: On-Screen Takeoff, PlanSwift, Bluebeam — all require manual measurement
Differentiator: One-click auto-measure. Computer vision trained on construction drawings. $299/user/mo — cheaper than a junior estimator's weekly salary.
Pricing: $299/user/month
Glazing: High
MVP: Upload a curtain wall elevation PDF. Let AI auto-measure glass area, frame lengths, and opening counts. Compare against a manual takeoff for accuracy and time.
What it does: All-in-one contractor platform covering the full job lifecycle — from first estimate to final invoice. Upload plans, photos, or project descriptions and receive structured takeoffs, scoped estimates, and professional proposals in minutes. YC S26.
