Revolving door planning for commercial buildings requires coordination between architects, MEP engineers, and door suppliers to ensure proper integration with building systems and traffic flow. This guide covers planning considerations for commercial building revolving door installations.
1. Traffic Flow Analysis
Perform traffic flow analysis during schematic design to determine door quantity and specifications. Count pedestrian and vehicle traffic patterns, peak hour volumes, and seasonal variations. Buildings with more than 500 daily users should consider multiple revolving doors to provide redundancy and manage peak traffic. Separate entrance zones for pedestrians and vehicles prevent conflicts and improve safety.
2. Adjacent Swing Door Requirements
Building codes typically require accessible entry alternatives to revolving doors for wheelchair users and persons with mobility impairments. Plan adequate space for adjacent automatic swing doors or sliding doors that comply with accessibility standards. The accessible entrance should be clearly marked and within reasonable proximity to the main revolving door entrance.
3. MEP Coordination
Revolving doors require dedicated electrical circuits with appropriate capacity for motor starting currents and electronic controls. Coordinate electrical service location with revolving door supplier to ensure adequate conduit routing. For buildings with building management system integration, coordinate communication protocols and control interface requirements during design phase rather than as a late-stage addition.
4. Structural Loading
Revolving door enclosures transfer significant loads to the building structure including door weight, dynamic loads during operation, and wind loads on the enclosure surface. Structural engineer must design appropriate support for the enclosure loads and coordinate foundation requirements with the architectural floor design. Heavy enclosures may require supplemental structural steel framing.
5. Phased Occupancy Considerations
Large commercial buildings with phased occupancy should consider temporary entrance solutions that maintain security while allowing early building sections to become operational. Revolving doors ordered for late phases should have final specifications locked during early design phases to prevent specification changes that could affect building systems coordination.
