Dholera SIR Lift Regulations: DSIRDA Elevator Building Codes

1. Building Height Thresholds for Mandatory Lifts

The requirement for installing elevators is determined by the total height and occupancy of the building:

• Buildings Exceeding 15 Meters (G+4 Floors & Above): Installation of at least one passenger elevator is mandatory. Walk-up staircases alone are not permitted for structures above 15 meters.
• Buildings Exceeding 24 Meters (High-Rise Towers): Must install at least two elevators, one of which must be designed to accommodate a medical stretcher.
• Hospitals and Nursing Homes: A dedicated medical bed/stretcher elevator is mandatory for all healthcare facilities with more than one floor, regardless of overall building height.
• Industrial Plants & Warehouses: Multi-level factory units must install heavy freight goods lifts with minimum carrying capacities of 2,000 kg to 5,000 kg.

2. Stretcher and Firemen Lift Specifications

To support medical emergencies and fire response, high-rise buildings must incorporate specialized elevator designs:

• Stretcher Lift Dimensions: The internal elevator cabin must measure at least 2.0 meters in depth by 1.1 meters in width (with a minimum door width of 1.0 meter), with a carrying capacity of at least 1,000 kg (13 persons) to accommodate an emergency ambulance stretcher and medical personnel.
• Firemen Control Switch: At least one lift in buildings taller than 15 meters must be designated as a Fire Lift. It must feature a key-operated Fireman’s Switch on the ground floor entrance lobby. When activated during an emergency, the switch immediately recalls the elevator to the ground floor, opens the doors, and gives exclusive control to emergency responders.
• Fire-Resistant Shaft Walls: The elevator shaft must be enclosed by concrete walls offering a minimum 2-hour fire resistance rating, with ventilated smoke relief openings at the top of the shaft.

3. Power Backup and Automatic Rescue Devices (ARD)

To prevent passengers from being trapped during power interruptions, all elevators in Dholera SIR must feature emergency backup systems:

• Automatic Rescue Device (ARD): Every passenger elevator must be equipped with an electronic ARD powered by an internal battery bank. If main grid power fails, the ARD automatically moves the elevator car to the nearest floor, opens the doors, and safely releases passengers.
• Dual-Power Grid Routing: High-rise residential towers and commercial centers must connect lift shafts to both Torrent Power’s main distribution feed and an on-site diesel backup generator with automatic transfer switches (ATS).
