New tools for construction, glazing & fabrication β€” curated for PGC
July 22, 2026
πŸ“Œ This week's theme: YC's 44-company construction cohort drops, Merlin ERP emerges, and AI procurement goes mainstream β€” Merlin (AI-powered construction ERP), Resolve (VR BIM review), Prolo (Β£4.2M AI procurement), Rudus (concrete AI takeoff), Helonic (AI clash detection + auto RFIs), and CentralComs (AI agents for property management) all target the industry's costliest operational bottlenecks. Plus: OpenConstructionERP v3.0 keeps maturing, Snaptrude offers free cloud BIM, and Togal.AI remains the gold standard for AI takeoff.

Merlin

ERP / Project Management

What it does: AI-powered ERP purpose-built for construction companies. Unifies project management, materials management, finance, and operations in a single platform. Tailored for modular construction, prefabrication, and manufactured homes. YC-backed.

Legacy alt: Sage 100 Contractor, Viewpoint, Jonas β€” all require heavy customization and lack AI-native features

Differentiator: First AI-native ERP for construction β€” not a generic ERP with construction modules bolted on. Built from the ground up for how contractors actually work.

Pricing: Not public (YC-backed, seed-stage)

Glazing: High

MVP: Sign up for early access. Map PGC's current workflow (estimating β†’ procurement β†’ fabrication β†’ install β†’ billing) and see which modules cover the gaps.

Resolve

CAD/BIM / AR-VR

What it does: Real-time collaborative BIM review platform combining VR/AR with traditional model viewing. Construction teams identify risks earlier, coordinate faster, and deliver higher-quality assets. YC-backed.

Legacy alt: Navisworks (clunky, desktop-only), BIM 360 (limited real-time collaboration)

Differentiator: Real-time multi-user BIM collaboration in VR β€” teams can walk through models together regardless of location. Built for mission-critical infrastructure.

Pricing: Not public (YC-backed, seed-stage)

Glazing: Medium

MVP: Upload a curtain wall or storefront model. Run a 30-min coordination session with the project team. Compare clash detection speed vs. current Navisworks workflow.

Prolo

Procurement / Supply Chain

What it does: AI-powered procurement platform for SME construction firms. Sources materials, equipment, and labour at competitive market rates. Includes embedded credit/deferred payment (up to 90 days). Just raised Β£4.2M seed from Triple Point Ventures.

Legacy alt: Manual supplier sourcing via phone/email, fragmented quotes, no payment flexibility

Differentiator: Combines AI sourcing with embedded finance β€” contractors can defer payments up to 90 days. Built specifically for SME contractors (PGC's exact size).

Pricing: Not public (seed-stage, launched July 2026)

Glazing: High

MVP: Source pricing for a standard glass order (e.g., ΒΌ" tempered, 1" IG units). Compare against current supplier quotes for price and lead time.

Rudus

Estimating / Takeoff

What it does: AI takeoff and estimation platform specifically for concrete contractors. Automatically identifies footings, walls, columns, and slabs from plans. Claims 70% reduction in estimation time and 3Γ— more projects won per year. YC S26.

Legacy alt: Manual takeoff with On-Screen Takeoff or PlanSwift, plus manual concrete volume calculations

Differentiator: Concrete-specific AI trained on structural drawings. Catches the surge in concrete demand from AI data center build-out.

Pricing: Not public (YC S26, seed-stage)

Glazing: Low

MVP: N/A for glazing directly. Worth watching as a benchmark for what AI takeoff can achieve in a single trade.

Helonic

CAD/BIM / Preconstruction

What it does: Analyzes PDF construction plans across architectural, structural, and MEP disciplines. Detects clashes and inconsistencies, then auto-generates draft RFIs. Integrates with Procore and Autodesk. YC S26.

Legacy alt: Manual clash detection in Navisworks + manual RFI drafting

Differentiator: Auto-generates draft RFIs from detected clashes β€” not just flagging issues but creating the documentation to resolve them. Saves "hundreds of thousands to millions per project."

Pricing: Not public (YC S26, seed-stage)

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.

CentralComs

Project Management / Operations

What it does: Deploys AI agents directly inside AppFolio, Buildium, and Yardi. Agents track maintenance calls, chase open tickets, and keep owners/tenants/vendors updated in real time β€” no human handoff required. YC S26.

Legacy alt: Manual call tracking, spreadsheets, email chains for maintenance coordination

Differentiator: Native integration with existing PM platforms β€” no migration required. AI agents make decisions and resolve multi-step workflows autonomously.

Pricing: Not public (YC S26, seed-stage)

Glazing: Low

MVP: N/A for PGC directly. The agent-in-platform pattern could apply to PGC's service/warranty call tracking.

OpenConstructionERP v3.0

ERP / Estimating

What it does: Free, open-source construction ERP with 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. v3.0 released June 2026.

Legacy alt: Sage 100 Contractor ($3K+/yr), Viewpoint ($10K+/yr), Jonas ($5K+/yr)

Differentiator: Completely free and self-hosted. Full CAD/BIM takeoff built in. Active development (v8.6.0 with vector DWG/DXF takeoff). No per-user licensing.

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 β†’ procurement β†’ change order workflow.

Snaptrude

CAD/BIM

What it does: Fully cloud-native BIM platform with AI-powered design tools. Free plan includes full BIM modelling, AI agent stack, and IFC export with no time limit. Parametric design, collaboration, 3D render. Browser-based β€” no install needed.

Pricing: Free (with paid plans for advanced features)

Glazing: Medium

MVP: Model a simple storefront or curtain wall elevation. Export to IFC and open in Revit to test interoperability. Use AI floor plan generation for a quick layout.

Togal.AI

Estimating / Takeoff

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 β€” all require manual measurement

Differentiator: One-click auto-measure. Computer vision trained on construction drawings. $299/user/mo β€” 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.

Foreman

Estimating / Project Management
