Located in Southeastern United States, the NFL Stadium is a two million square foot state-of-the-art facility for a variety of teams and events. This will replace the existing stadium and provide more seating and parking spaces for guests.
Southland Engineering provided computational fluid dynamic (CFD) analyses, as well as full mechanical and plumbing engineering. Seating more than 71,000 and expandable to 75,000, the multipurpose stadium features a retractable roof, 24 bars, 190 suites, and three concourse levels. The facility is a third generation operable roof stadium that will be primarily used for sporting events. It will host marquee events, such as Southeastern Conference Championship games, Chick-Fil-A Bowl, NCAA Football National Championship games, and NCAA Men’s Final Four games.
Approach & Innovations
To provide cost-effective solutions, Southland Engineering utilized CFD analyses to prove thermal comfort and HVAC load verification. The verification eliminated approximately one million pounds of sheetmetal for the bowl duct and saved approximately eight million dollars in installation costs.
Prevention through design concepts were incorporated into the assembly of the roof trusses to prevent tradesmen from working 300 feet above grade to install the roof storm system piping. Similarly, the bowl ductwork was designed as a multi-trade assembly to simplify the overall installation and provide a safe working environment. Additional examples of prefabrication include bathroom batteries and main service corridor piping racks.
Throughout the concourse, approximately 673 concessions are available for fans to enjoy – some of which include kitchen/cooking equipment. Per code, the grease exhaust connections from the fume hood must be constructed with grease rated construction which includes welded ductwork, sloping of the ductwork, and grease traps. With most of these connections occurring inboard of the building’s concourses, a significant distance was traveled to connect the hoods to the architectural exhaust louvers. Southland Engineering utilized ultraviolet kitchen grease hoods and a scrubber system to provide significant savings for the owner. This enabled the use of galvanized ductwork after scrubbers, which eliminated the need to slope duct as well as minimizes risk of discoloration to the building’s exterior near louver exhaust points.
Southland Engineering designed a 750,000-gallon reclamation water system to provide significant water savings. The system collects rainwater and reuses it for the cooling tower makeup water and the stadium irrigation system. In conjunction with UV Systems, the design team also provided a hybrid gravity and siphonic roof drain system. This added to the savings, by cutting the need for deep trenches to be used for the rainwater system.
