Revit MEP Automation for HVAC, Electrical and Plumbing Workflows

MEP engineers juggle calculations, standards and constant coordination changes. Discipline-specific Revit automation keeps models, calculations and drawings in step.

HVAC automation

  • Size ducts from airflow using equal friction or velocity methods.
  • Assign air terminals to spaces from load calculations.
  • Check system connectivity and unconnected ends.
  • Generate equipment schedules with data from manufacturer catalogues.

Electrical automation

  • Create circuits by room or area according to rules.
  • Balance loads across phases and update panel schedules.
  • Place lighting fixtures on grids from lux targets.
  • Generate single-line diagrams from the model.
  • Cable length and cable tray fill calculations.

Plumbing automation

  • Pipe sizing from fixture units or flow rates.
  • Slope checks on sanitary pipes.
  • Riser diagrams and plumbing schedules.

Across all MEP disciplines

AutomationBenefit
Sleeves and openings at structural clashesFaster coordination with structure
Hanger and support placementConsistent, countable supports
Spool and fabrication drawingsDirect hand-over to prefabrication
Parameter and naming checksClean data for handover
Tagging and annotationComplete, consistent drawings

Example: automatic sleeve placement

for each pipe/duct crossing a structural wall or floor:
    compute intersection point and element size
    choose sleeve family by size + insulation + clearance
    place sleeve hosted in wall / floor
    write reference IDs for tracking
report: 312 sleeves placed, 4 conflicts need review
MEP automation turns calculations and standards into model changes automatically.
