How do I read the equipment schedule to know which VAV goes in which room?

2nd YearBlueprint ReadingYELLOW · Check First

Locate the specific equipment tag number (e.g., VAV-1-04) marked on the floor plan. Go to the Equipment Schedule Sheets (usually found at the start or end of the 'M' blueprints pack). * Find that matching tag row to read its required CFM airflow rating, inlet size, electrical voltage supply needs, and minimum control clearance requirements.

Field checklist

Ask Foreman

Hey boss, I’m checking blueprint reading: How do I read the equipment schedule to know which VAV goes in which room? I found the likely issue and want to verify the next step before I lock it in. Do you want me to adjust it now or check the drawing/detail first?

Verify before acting

Use this as training guidance. The foreman, approved drawings, project specs, manufacturer installation instructions, employer safety policy, and AHJ/code requirements always control the final answer.
