Frank Eppink, senior project manager for HCBeck, contacted Supreme at the early phases of preliminary construction. Eppink looked to Supreme for assistance in writing the roofing specification, which would provide his client with one guarantee encompassing all types of roofing systems to be installed. The structures as designed would require several different roofing systems to provide moisture protection and long-term performance in all specific roof areas. Johns Manville was selected by Supreme as their preferred roofing manufacturer due to their wide selection of products, past performance and exceptional technical support.

 

Larry Barnard, project manager with Supreme, contacted Joel Lewallen of Johns Manville to enlist his expertise in the selection of these roofing applications. Supreme then provided budget pricing for all JM approved systems to HCBeck. After numerous meetings addressing all concerns, the team selected various JM roofing systems using three-ply gravel surfaced BUR, DynaGlas® FR modified bitumen, UltraGard® PVC single ply membrane and UltraGard EPDM single ply membrane.

 

"This was a roofing project made for Johns Manville," said Joel Lewallen, the Johns Manville representative on the job. "Not only were we able to provide a single guarantee, but we also were able to provide some unique solutions to challenges faced on the job."

 

The Town Hall, which is the centerpiece of the downtown development, had a number of very 

unusual base flashing details attributed to the building's unique design. This required the close coordination of Supreme Systems and Lewallen to develop and construct flashing details that could stand the test of time and be included under the Johns Manville guarantee.

 

BUR and modified bitumen roofing systems were used on the majority of the project. For the BUR roofing systems, 2.1 inch E'NRG'Y 2™ polyiso insulation was placed over the steel deck followed by ¾" Fesco® Foam roof insulation. Tapered Fesco was used to provide required slope to drains. Three plys of Type VI GlasPly® Premier felt were then applied. The modified bitumen specification consisted of three plies of Type VI GlasPly Premier felt with fire rated SBS DynaGlas FR used for the finish ply.

 

At the Town Hall, fully adhered 50 mil reinforced UltraGard SR-50 PVC was used on areas with extreme slope and the entry canopies. UltraGard EPDM was used on the high parapet walls above the flashing.

 

Larry Barnard suggested that using PVC on the canopies made the project go much faster and helped them to meet a very tight deadline. "We would not have been able to obtain an all-inclusive warranty for the walls and the roofing system with anyone other than Johns Manville," said Barnard. "They were very helpful throughout the project."

 

Supreme Systems is rather unique in the roofing industry, which allowed them to handle the Southlake Town Center project. They have specially trained crews for each type of membrane which allows them to remain focused on each different membrane type. The company was founded in 1987 and has approximately 250 employees. Tim Rainey is in charge of operations, Jeff Sterrett is in charge of financing and Keith Post oversees sales and estimating.

 

"For many years, Supreme and HCBeck have created a unique relationship by working together on just this type of project," said Barnard. "This interaction between general contractor and subcontractor has led to many successful projects. Creating this partnership between HCBeck, Supreme Systems, Inc., and Johns Manville has provided this owner the best in roofing solutions."

 

Renowned architect David Schwartz designed the Town Hall. Beck Architecture, a division of HCBeck, designed the remainder of the project.
