Duke University is an internationally recognized private research institution located in Durham, North Carolina. Founded in 1838 and with a campus spanning over 8,600 acres, this abundance of land was a boon to the arts programs at Duke University.
CFE, Inc. (a division of Evans Roofing Company, Inc.), a national leader in the roofing industry, was retained to complete a complicated roofing project at the newly constructed Arts Center. Skanska USA was the GC/CM on record for the project and selected CFE, Inc. based on their record for safety and quality.
The Duke University New Arts Center was designed by the architecture firm of William Rawn Associates, Architects, Inc. of Boston, Massachusetts. The firm wanted to compliment the adjacent Nasher Museum of Art with the design of the new structure. As for the roofing portion of the structure, Sika Sarnafil G4-10 roofing membrane was selected because of energy savings and performance history. CFE, Inc. has enjoyed a 30 year history installing Sika Sarnafil roofing membranes. CFE, Inc. field associates prefer working with Sika Sarnafil for ease in flexibility and weldability during installations.
The Duke University New Arts Building has six different roof areas, at various levels that were part of the CFE, Inc. scope of work. All low-slope areas were specified Sarnafil and their scopes are as follows:
Area one scope was loose lay 1/4” per foot tapered polyisocyanurate board insulation with a minimum R-value of 30, mechanically fasten 1/2” Dens Deck prime over insulation and adhere a white 72 mil Sika Sarnafil membrane.
Area two and two A scope included installing Sika Sarnvap vapor barrier over concrete deck, adhere 1/4” per foot tapered polyisocyanurate board with an insulation minimum R-value of 30 and then adhere 1/2” Dens Deck prime over insulation, adhere white and gray 72 mil Sika Sarnafil membranes.
Roof area six consisted of loose laying 1/8” per foot tapered polyisocyanurate board insulation with a minimum R-value of 17.4 over plywood roof deck, then mechanically fasten 1/2” Dens Deck prime over insulation and adhere gray 72 mil Sika Sarnafil membrane.
A tight completion schedule can make for a multitude of issues with roofing projects but the ability to install Sika Sarnafil products with ease alleviated issues. This helped keep the project on schedule.
Safety is always a top priority for CFE, Inc. and with this project it wasn’t any different. Team Leaders needed to ensure that all CFE, Inc. associates and subcontractors followed all OSHA regulations, in addition to CFE, Inc.’s, Skanska and Duke University rigorous site safety policies. “Every associate was protected by a combination of a guard rail system installed at perimeters and when needed personal fall arrest systems during the duration of the project. Maintaining this extreme level of safety is always a challenge under a tight schedule but we were able to achieve 100% fall protection keeping everyone safe” said Aaron Whaley, Construction Risk Specialist for CFE, Inc.
In conclusion, this project was a success thanks to the collective efforts of CFE, Inc. Associates, Skanska USA, Duke University and Sika Sarnafil. “This project, from start to finish, lasted one year and three months. This included multiple mobilizations for our crews. Duke University and Skanska are extremely pleased with CFE, Inc.’s quality, safety, workmanship and our teamwork approach to the project” said Mike Ruhmel, Vice President of Operations for CFE, Inc. North Carolina. “We are proud to have the opportunity to install quality products from Sika Sarnafil on a regular basis. We, and our clients, understand the quality they are getting from the beginning.”
All of us at CFE, Inc. are proud of the work we’ve done on the New Arts facility and the protection from the elements we and Sika Sarnafil can provide to the art programs of Duke University.
