Why MEPSub

Built specifically for MEP contractors

Procore is built for general contractors — not subs. ServiceTitan and Housecall Pro are residential dispatch tools — not commercial construction. Spreadsheets don't scale. MEPSub is the only platform built from the ground up for commercial MEP subcontractors doing real projects with GCs, submittals, specs, and contracts.

FAQ

Common questions

🔧What MEP trades does MEPSub support?
MEPSub covers Divisions 21–28 of the CSI MasterFormat: fire suppression, plumbing, HVAC, refrigeration, electrical, communications, and electronic safety. Our database includes 145 spec sections with 218+ real manufacturer names, 13,000+ material prices, and pre-built assemblies for common MEP configurations.
📊How does the estimate-to-project workflow work?
Create an estimate with sections, line items, and assemblies — pull pricing from the built-in cost book or enter your own. Generate a professional PDF and send it. Track through the visual pipeline (Draft → Bidding → Approved → Awarded). When approved, convert to a project with one click — all estimate data, client info, and scope transfers automatically. Then generate invoices, POs, transmittals, and more directly from the project.
🤖How does the AI work?
MEPSub uses advanced AI models fine-tuned for MEP construction workflows. Upload a spec book — AI extracts equipment and creates submittals. Draft an estimate — AI generates scope of work and verifies pricing. Need an RFI? Describe the issue and AI drafts it. Plus a full AI chat assistant you can ask anything — from code questions to installation troubleshooting. AI handles spec parsing (with OCR), price verification, SOW writing, RFI/CO drafting, drawing classification, product comparisons, and O&M compilation.
💲What's in the Pricing Intelligence module?
The cost book contains 13,000+ material prices across 39 CSI sections (Divisions 21-28) with full-text search. It integrates Bureau of Labor Statistics data for construction labor rates, Federal Reserve (FRED) data for material price trends, and regional cost factors for location-adjusted pricing. Browse by division, search by keyword, and import items directly into your estimates.
🔗How does the GC Review Portal work?
From any submittal, click "Send for Review," enter the reviewer's email, and set an expiry. They receive a branded email with a secure link. They open it, review materials, choose an action (Approved, Approved as Noted, Revise & Resubmit, or Rejected), add comments, and submit — all without creating an account. You're notified instantly.
📱Does it work on mobile?
Yes. MEPSub is a Progressive Web App (PWA) — install it on your phone and it works like a native app. Full touch-optimized interface with 44px touch targets, bottom navigation, iOS-style interactions, and the ability to create estimates, manage submittals, browse the cost book, and send invoices from the jobsite.
