Project Description

North American Dismantling was contracted by Northwest Airlines as General Contractor to design, demolish and build structures known as Concourses C, D, E, F, and G at Detroit Metropolitan Wayne County Airport.The design phase of the project consisted of pre-design, concept design, schematic design, 30% Design Development, 75% Design Development, 100% Design Development, shop drawings and as-builts. These design drawings included all demolition areas, architectural systems, structural systems, mechanical systems, electrical systems, security systems, all systems to remain active, a safety phasing plan to be submitted to the FAA, and all new construction located at interface of facilities to remain.

Prior to the start of the project North American Dismantling constructed a Jersey Barrier Wall around the perimeter of Concourse D, E, F, and G and a separate wall around Concourse C. The Barrier Wall was approx. 4’-0” in height, every 20’-0” flashing yellow lights, stripping on taxiway side. The taxiway side of the Barrier Wall was 75 ft to 130 ft from the center of the taxiway and 50 ft from the edge of the structures to be demolished. Aircraft would come within 10 feet or closer to the Barrier wall on a daily basis.

Concourse C consisted of approximately 55,200 sq.ft. It was a one story raised steel structure set on concrete columns 20 ft high and approx. 700 ft long, 80 ft wide and 20 ft high. The separation of Concourse C from the existing terminal was conducted on an expansion joint west of Gate 12. It was located in an active area where planes were loading and unloading passengers continuously. Dust control measures were applied using fire hoses and man lifts.

Concourse D was a concrete structure including a concrete roof approx. 36,400 sq.ft set in footprint consisting of two floors totaling 72,800 sq.ft. It was approx. 40 ft long, 80ft wide and 40ft high. The first floor was set over a existing tunnel are approx. 310’x25’x14’ and a concrete wall was installed in the tunnel at the separation point prior to the opening of the tunnel. The separation point from the existing terminal was at Column line 5 to maintain functioning mechanical rooms and egress.

Concourse E was a concrete structure with a concrete roof approx. 37,200 sq.ft in footprint consisting of two floors totaling 74,400 sq.ft. It was approx. 400 ft long, 80ft wide and 40ft high. The first floor was set over a existing tunnel are approx. 320’x25’x14’ and a concrete wall was installed in the tunnel at the separation point prior to the opening of the tunnel. The separation point from the existing terminal was at Column line 5 to maintain functioning mechanical rooms and egress.

Concourse F was a concrete structure with a concrete roof approx. 61,100 sq.ft in footprint consisting of two floors totaling 122,200 sq.ft. It was approx. 250 ft long, 90ft wide and 40ft high with a 200ft diameter rotunda located at the west end. The first floor was set over a existing tunnel are approx. 320’x25’x14’ and a concrete wall was installed in the tunnel at the separation point prior to the opening of the tunnel. Concourse F also had a triangular shaped one-story structure raised on concrete columns to the south.

Concourse G was removed in its entirety. It was a one story steel structure with a metal deck approx. 46,000 sq.ft. It was approx. 450 ft long, 100ft wide and 40ft.
In addition to the selective demolition and new construction of the existing Concourses. North American Dismantling also was required to remove six (6) underground diesel and gasoline fuel storage tanks and 4000 cubic yards of petrol-chemical contaminated soil. Five of the tanks were 10, 000 gallons with one 3,000 gallon tank.

All demolition and construction was conducted with safety and security in mind at all times.
