DesignFlow Build
AI ERP for MEP Contractors
AI blueprint takeoff, estimating, scheduling, job costing, and field service in one platform — built for mechanical, electrical, and plumbing contractors, not retrofitted from generic construction software.
MEP contractors win or lose on the accuracy of the takeoff and the tightness of the schedule — yet most run estimating in spreadsheets, scheduling in a separate tool, and accounting somewhere else. DesignFlow Build reads your mechanical, electrical, and plumbing plan sets, builds the takeoff and bill of quantities automatically, and carries that scope straight into estimating, CPM scheduling, job costing, and field service — one connected system tuned for how MEP work actually runs.
AI takeoff that speaks MEP
Upload a plan set and, in one run, the AI reads project legends (M0.0, E0.0, P0.0), detects symbols, counts fixtures, traces pipe and duct runs, and reads and counts the equipment schedules printed on the plans — all using a 200+ term MEP vocabulary mapped to CSI codes — then aggregates it into a bill of quantities and a priced estimate, with a verifiable 3D model to check the counts.
200+ term MEP vocabulary across mechanical, electrical, and plumbing
Symbol detection, fixture counts, and pipe/duct run length takeoff
Equipment schedules read and counted on the plans, tag by tag
Estimating built for MEP scopes
Turn the takeoff into a priced estimate without re-keying. Build assemblies, apply per-configuration equipment pricing, and track change orders against the original scope.
Takeoff flows directly into the estimate — no double entry
Assemblies and per-config equipment (CFM, size, mount, model)
Change-order tracking against the awarded scope
Scheduling and field service in one place
Generate a CPM schedule from the scope, then run the field side — service dispatch, time tracking, and a mobile app with voice data entry — against the same project record.
AI-generated CPM schedule with critical path and what-if scenarios
Service dispatch and time tracking for service-and-projects shops
Mobile field app with voice data entry from the jobsite
Real job costing and accounting
Track committed costs, change orders, and cash against every job with a true general ledger underneath — so margin erosion shows up while you can still act on it.
Job costing tied to live project and field data
AR/AP and general ledger with double-entry posting
Progress billing and retainage tracking
Frequently asked questions
Yes. DesignFlow Build covers all three MEP disciplines plus HVAC and sheet metal, including trade-specific takeoff, equipment schedules, and assemblies. Firms that run both construction projects and a service division can manage projects and service dispatch in the same system.
Upload a PDF plan set and the AI identifies the legend pages, detects symbols, counts fixtures, and traces pipe and duct runs, producing a bill of quantities and a 3D spatial model you can review and adjust before it flows into your estimate.
Implementation is typically 2-4 weeks with guided onboarding and data migration. For a representative $10M contractor, eliminating roughly 1.4 full-time positions of manual takeoff, data entry, scheduling, and reporting work yields an approximately 2-month payback on the subscription — counting hard labor savings only.
