Legacy alt: Manual cross-referencing of drawing sets + manual RFI drafting
Differentiator: Catches coordination errors in preconstruction (not mid-build), preventing costs that routinely reach hundreds of thousands per project.
Pricing: Not public (YC S26, seed-stage)
Glazing: High
MVP: Upload PGC glass shop drawings against structural/MEP plans to catch clashes before fabrication.
What it does: Open-source construction ERP with 71 modules including BOQ, PDF/CAD/BIM takeoff, AI cost matching. 42 regional catalogues, 21 languages. AGPL-3.0. v3.0.
Legacy alt: Sage, Viewpoint, or other commercial construction ERPs ($10k+/year)
Differentiator: Free, open-source, self-hosted. Massive module library. AI cost matching across 42 regional catalogues.
Pricing: Free (AGPL-3.0, self-hosted)
Glazing: High
MVP: pip install openconstructionerp — immediate self-hosted trial with inventory and BOQ modules.
What it does: Modernizes construction procurement with AI-powered supplier matching, quote comparison, and purchase order management. Raised £4.2M (a16z-backed).
Legacy alt: Manual phone/email supplier sourcing + paper POs
Differentiator: a16z-backed with focus on construction-specific procurement workflows. AI matches suppliers to project needs.
Pricing: Not public (likely SaaS, per-project or subscription)
Glazing: High
MVP: Test supplier matching for glass/material procurement on a current PGC project.
What it does: 360° photo capture on job sites with AI-powered visual documentation. Creates a visual timeline of construction progress. Tracks installed work against plans. "Google Street View for construction sites."
Legacy alt: Manual progress photos + daily reports
Differentiator: Automated 360° capture with AI that maps photos to BIM/plans. 1,000+ data center projects milestone.
Pricing: Per-project or subscription (established company)
Glazing: Medium
MVP: Document glass installation progress on a large project and verify against shop drawings.
What it does: AI-powered takeoff tools specifically targeting the MEP (mechanical, electrical, plumbing) estimating bottleneck. Automates quantity extraction from digital plans.
Legacy alt: Manual takeoff with Trimble's own legacy tools or Bluebeam
Differentiator: From Trimble (industry giant) — integrates with existing Trimble ecosystem. AI layer on top of proven estimating tools.
Pricing: Likely add-on to Trimble estimating products
Glazing: Medium
MVP: If PGC uses Trimble products, evaluate as a natural upgrade path.
What it does: AI-powered construction takeoff and estimating platform. Automatically measures areas, counts objects, and extracts quantities from construction plans.
Legacy alt: Manual takeoff with Bluebeam or PlanSwift
Differentiator: One-click takeoff from uploaded plans. Trained on construction-specific drawings. Fastest in class for speed.
Pricing: Subscription-based (per-user/month)
Glazing: High
MVP: Upload glass shop drawings for automated window counts, glass areas, and curtain wall measurements.
What it does: AI-powered bid matching platform that saves 8+ hours/week vs. manual portal checking. Matches contractors to relevant project opportunities.
Legacy alt: Manually checking Dodge, ConstructConnect, or other bid boards
Differentiator: AI learns which projects are relevant to your specific trade and capacity. Saves hours of manual filtering.
Pricing: Likely subscription (competitors $3k–$12k/year range)
Glazing: High
MVP: Set up PGC trade profile and see if relevant glazing bids surface.
What it does: AI construction software platform for scheduling, cost management, and project delivery. Uses predictive analytics to forecast delays and cost overruns.
