The Dallas City Performance Hall, Dallas, is a 70,000-square-foot, 750-seat professional theater located in the 68-acre renowned City of Dallas Arts District. The $40.5 million facility opened in September 2012, and is designed for theater, music and dance performance companies. The project has received the North Texas Roofing Contractors Association’s 2012 Golden Hammer award and is being submitted for LEED Silver certification. The hall features a 25,000-square-foot roof with Kalzip Alupluszinc 65/400 continuous panels in varying lengths from Valparaiso, Ind.- based Kalzip Inc. The varying lengths form a natural wave that mimics the flow of music and sound. Kalzip’s zinc-coated aluminum panels were used as the visible exterior surface and Kalzip’s sounddampening material was added to the roofing assembly for additional acoustic mass.

The project was designed by a joint partnership of the Skidmore, Owings & Merrill LLP as design architect, and Corgan Associates Inc., as architect of record. R. Kirk Johnson, associate at Corgan, was the project director responsible for project delivery and sustainability. Kalzip engineers provided product information, technical advice, construction submittals and on-site supervision.
“Kalzip’s data base of acoustical information allowed Jaffe Holden, the project acoustician, to provide guidance for product usage,” Johnson says. “A multi-layered sandwich assembly consisting of structural metal decking, high-density acoustic batt insulation, rigid board roofing insulation, Kalzip sound dampening mat, plywood, weather barrier, anti-drumming membrane, and zinc-coated aluminum panels was used as the acoustic and thermal barrier. All of the roofing assembly was applied on-site.”
McCarthy Building Cos. was the construction manager, and the roofing subcontractor was Castro Roofing. According to Scott Brown, sheet metal manager for Castro and manager for this project, logistics were a primary concern on his portion of the work on this downtown Dallas facility.

“The location and restrictions on getting materials in and out were a major consideration,” explains Brown. “But our biggest challenge was getting the panels up to the roof. The panels were different lengths, with the biggest ones being 305 feet long. To get those panels up we had to close off the area because they reached out into the street. So we closed the street at three in the morning to run the panel up to the roof. It took 22 men to handle the panel coming out of the fabricating machine and 22 more men to pull it up on the roof. It was more of a logistical challenge because the panels are not heavy and they have a natural finish.”
