Washington Dulles International Airport

Chantilly, VA

National Fire Protection has a long history of work at Washington Dulles International Airport. The following projects are just a sample of NFP’s extensive experience in airport construction.

Early Finish Walkback Tunnel Package

This project was a temporary walkback tunnel constructed in late 1998. The tunnel provided an egress corridor from the non-secure area through the secure area prior to the construction of the first walkback tunnel (listed below). This was a design-bid-build project.

East APM Tunnel and Station

This project encompassed the East APM (automatic people movers, a moving floor style conveyor) building and the underground train tunnel that connects all of the stations. This included almost a mile of dry standpipes in the train tunnels, a water mist system (complete with mist systems pumps and day tanks) with 280 mist fog nozzles at each transition to the station in the APM station platforms, and wet systems for the multiple levels of the APM station. This was a design-bid-build project.

International Arrivals Building Expansion

This project consisted of a new addition to the existing customs area for international flights, which includes the inspection, ticketing, and process for all inbound international flights. As part of the renovation, new baggage conveyors were installed from the basement level to the ground level to allow for the processing of baggage for all new arrivals. Two new “TUG” Ramp dry systems were installed as to protect the covered ramp in which the airport transfers the baggage from the aircraft to the building for delivery to the customer.

The scope of work included wet and dry sprinkler systems, standpipes, and remote fire hose valves. Approximately 3400 sprinklers were installed. The project consisted of both new and renovation construction and was done over three phases.

Main Terminal

This project was two packages at the Main Terminal, starting in the late 1990s. A design-bid-build project, the work consisted of renovations of the existing main terminal and the new addition.

Midfield Terminal

The project was a design-build contract to provide a small commuter plane terminal that would attach to the existing B Concourse building. This project has window sprinklers along the glass, multiple wet systems inside, and a 6” fire loop that passes through the building and tied into the soon-to-be constructed dedicated fire main

Pedestrian Walkback Tunnel

Pedestrian Walkback Tunnel Finish Package

NFP was a partner in the construction of the two walkback tunnels at the airport; both were design-bid-build projects. The first tunnel was in 2001-2002; the second in 2008-2009. These tunnels were under the existing airfield apron (airside) and tied the Main Terminal into the existing Concourse B building for passenger traffic between the two.

Tier 2 / Concourse C Connector

The project consisted of a new pedestrian tunnel that connected the Tier 2 area and the Concourse C area. Within in this area, the construction consisted of the installation of two APMs. Sprinklers are located above a floating ceiling and were located as per the meticulous coordination with the Architect. A preaction system was provided to protect the mechanical equipment room for the control room for the moving floor.

The scope of work included wet, dry, and double-interlocked preaction systems, standpipes, and remote fire hose valves. 243 sprinklers were installed in the 1000-foot tunnel.

Water Mist Systems

NFP is responsible for the inspection of the airport’s water mist system. NFP is contracted directly to the Metropolitan Washington Airports Authority (MWAA), with the contract covering all four of the APM stations.

West Concourse & APM Station

NFP began work on the new West APM Station and B-12 buildings in 2005. These were two new buildings that connect to the existing Concourse B building. The B-12 building added more gates and a mechanical basement. The West APM Station is the building where the underground train comes into the Concourse B building; it has five levels with the train tunnel for that station. This portion of the work included a water mist system (complete with mist systems pumps and day tanks) with 280 mist fog nozzles at each transition to the station in the APM station platforms and wet systems for the multiple levels of the APM station. This was a design-bid-build project.
