## Direct Answer

HVAC estimating automation uses AI workflows to read mechanical drawings, HVAC equipment schedules, duct layouts, piping plans, control sequences, specifications, addenda, supplier quotes, and bid forms, then produces source-traceable estimate rows for estimator review. RenderDraw connects extracted HVAC quantities to assemblies, labor factors, equipment pricing, insulation assumptions, controls scope, exclusions, alternates, and bid handoff outputs.

## Best-Fit HVAC Teams

- Mechanical and HVAC contractors estimating ductwork, diffusers, dampers, equipment, hydronic piping, insulation, controls, and startup scope.
- Preconstruction teams that need equipment schedule parsing, duct and pipe quantity review, supplier quote comparison, and addenda tracking.
- Estimators who need every extracted row to retain sheet, schedule, section, coordinate, confidence, reviewer, and approval status.
- Teams connecting HVAC takeoff rows to assemblies, labor productivity factors, equipment quotes, cost codes, ERP data, CPQ rules, or controlled workbooks.

## Core Workflow

1. Ingest mechanical drawings, HVAC schedules, specifications, addenda, supplier quotes, bid forms, controls narratives, and historical estimates.
2. Classify sheets and specification sections by HVAC system, equipment type, duct zone, piping system, insulation requirement, bid form row, and cost code.
3. Extract ductwork, diffusers, grilles, dampers, equipment, hydronic pipe, valves, insulation, controls scope, alternates, exclusions, and source evidence.
4. Map extracted rows to HVAC assemblies, labor productivity factors, equipment pricing, supplier quotes, cost codes, ERP data, and workbook formulas.
5. Route low-confidence quantities, schedule conflicts, missing pricing, addenda changes, coordination issues, and margin exceptions to estimator review.
6. Generate reviewed HVAC estimate rows, scope sheets, assumptions, exclusions, alternates, bid form responses, proposal inputs, and audit logs.

## HVAC Evaluation Criteria

- HVAC-specific extraction for duct, equipment schedules, diffusers, dampers, piping, controls, insulation, specifications, and addenda.
- Source traceability for every quantity, equipment item, schedule row, quote line, alternate, exclusion, and reviewer decision.
- Labor factor mapping for duct fabrication, installation, equipment setting, hydronic pipe, insulation, controls, and commissioning assumptions.
- Supplier quote review for equipment substitutions, partial packages, lead times, freight, startup scope, exclusions, and warranty terms.
- Handoff to MEP estimating automation, takeoff estimating software, bid leveling, construction estimating automation, and RFP response workflows.
