Cargo · Life Safety Air Cargo Facility
Life Safety Modernization
Complete life safety modernization of a 150,000 square foot air cargo facility: full sprinkler system replacement, a new fire pump house, and 16 inch underground mains installed beneath an active semi truck court — with cargo operations running throughout.
The challenge
An air cargo terminal cannot pause. Freight arrives on aircraft schedules, and a shutdown propagates to carriers, forwarders, and customers within hours. This project required replacing the facility's entire fire protection system while that facility stayed in continuous operation — and running new 16 inch underground mains directly beneath the truck court that every inbound and outbound load crosses. The underground work alone meant opening, sequencing, and restoring sections of the busiest paved surface on the property without ever closing it.
Dunn's scope
- Prime contractor for the full life safety modernization
- Complete sprinkler system replacement across the facility footprint
- New fire pump house — structure, equipment, and commissioning
- 16 inch underground fire mains beneath an operating semi truck court
- Electrical scope for fire pump power and life safety circuits, self performed by Dunn's electrical team
- Phasing, permitting, and authority having jurisdiction coordination
Execution
The facility was divided into zones so that fire protection coverage was never absent from an occupied area — new system sections were installed, tested, and accepted before the corresponding legacy sections were taken out of service. The truck court was trenched in segments sized to be opened and made trafficable within a single operating window, so freight routing shifted rather than stopped. Fire watch and AHJ coordination ran continuously alongside construction.
