Lucas Oil Football Stadium
Project: Massive ductowrk - some pieces over 9-1/2 feet in diameter - needed to deliver 1.3 million cfm of fresh air to over 60,000 attendees at an Indianapolis Colts football game.
Product: Custom Air Duct System
Payoff: 1,486 linear feet of Semco 2-inch dual wall spiral duct snakes around the perimeter of the stadium, supplying all the conditioned air to the bowl. The interior duct is made of perforated steel and the exterior duct is galvanized sheet metal, with two inches of fiberglass insulation sandwiched in between. The stadium bowl ductwork will deliver conditioned air from supply air discharge plenums in all four corners of the stadium, with each quadrant being served by four dedicated air handling units (AHUs). Supply air from each set of four AHU’s discharges into a larger common discharge plenum, which has multiple taps from it that supply the spiral duct in the arena bowl. The sheet metal is bent and crimped to achieve true spiral seaming; it is not rolled and welded which would have been unacceptable in appearance.
