AI Drawing Analysis for HVAC Engineers

HVAC take-offs are brutal — thousands of metres of duct, dozens of terminal units, and a plant schedule the size of a phone book. PlanScanAI does the reading for you so you can focus on design intent and installation quality.

How PlanScanAI helps

Mechanical drawings punish manual review. Ductwork runs span multiple sheets. Plant schedules hide in fine-print legends. Terminal units blend into architectural background. A missed FCU or mis-sized damper cascades into commissioning pain and profit loss.

PlanScanAI reads M&E drawings with trade-tuned logic. Hand it a ventilation plan, pick ‘Mechanical / HVAC’, and ask for exactly what you need — VAV boxes, FCU types, duct diameters, grille sizes, plant items with capacities. The output is structured, sorted and ready to drop into your take-off sheet.

What PlanScanAI extracts from HVAC drawings

Tuned for CIBSE conventions and UK plant-schedule formats.

  • Air handling units, make-up air units and roof-top units with capacities
  • Fan coil units — ceiling, floor, cassette, with model references
  • Variable air volume (VAV) and constant air volume (CAV) boxes
  • Ductwork runs — supply, return, extract, kitchen extract with diameters
  • Grilles, diffusers and louvres with sizes and types
  • Volume control, fire, smoke and motorised dampers
  • Chillers, boilers, calorifiers, buffer vessels and pump sets
  • Heat recovery units, MVHR systems and thermal wheels
  • Plant schedules with duties, flow rates and electrical loads
  • BMS points, sensors, thermostats and actuators
  • Refrigerant pipe runs with sizes and insulation
  • Access panels, anti-vibration mounts and duct supports
