ARCHITECTURAL PLANS(Minimum scale of plans to be 1/8”=1’. Single line drawings are not acceptable except as noted– plans must be drawn to show wall thickness)
HVAC plans should indicate the locations for shafts, corridors, occupancy separations or other fire rated construction, the routing of duct work, locations for fire and smoke dampers at the penetrations through the fire rated construction and design criteria for outside air. Indicate locations for mechanical equipment and note the weights of equipment so that structural support can be verified. A separate mechanical permit is required and must be applied for prior to issuance of the building permit.
