Single Abstract

341358 - Innovation at Large, A Stadium Case Study

Friday, April 20
1:30 PM - 3:00 PM
Location: 203BC

The new Mercedes Benz Stadium, the home of the NFL's Atlanta Falcons and MLS's Atlanta United will feature a host of engineering innovations in its pioneering design. The 75,000 seat stadium features a 723' long span steel retractable roof with 8 moving petals that open like a camera lens in an optical illusion, where the petals appears to rotate, but uses standard equipment. This dramatic, unprecedented, movement opens the roof in less than 10 minutes. The moving petals cantilever up to 223' from the fixed roof, creating a 105,000 sf opening when opened. We will share the thought proceses behind this approach and how it was implemented.
The roof also supports at the center of its span, a 58' tall, 360-degree LED video scoreboard, the largest in sports. The scoreboard is supported along the sides of the trusses, integrated onto the structure, to allow uninterrupted views to the sky when the petals are open.
The geometrically complex facade is clad in single skin ETFE, a light weight and translucent material, its first use in the United States. The facades lean both towards and away from the building in large triangular facets, a move a away from the more typical curvilinear sports stadium facades.
The building is also on track to be the first LEED Platinum stadium. This presentation will focus on the innovative approach of the team in an effort to create a icon for Atlanta, as requested in the RFP. It will educate the participants on the various technology employed from the initial concept, to construction documents, through an atypical 3D approach checking over 50,000 3D steel shop drawings. The difficulties of innovation in large scale projects will be discussed, especially in light of the fast track schedule and a discussion of engineering solutions to the many challenges will be presented.
