project details
01
GRADY HOSPITAL | ATLANTA, GA
80 Gilmer Street
CASS - Center for Advanced Surgical Services
This new construction project was a vital addition to the largest hospital and trauma center in Atlanta. Built by Skanska USA, the Grady Hospital CASS project presented unique challenges, including navigating the complexities of COVID-19 and related supply chain disruptions. The work was conducted in an active hospital environment, with the facility overwhelmed by emergency cases and COVID patients.
At the outset, there was no clear protocol for managing construction safety during a pandemic. However, the team quickly implemented a comprehensive safety plan, including regular testing, to ensure the project met its deadline despite the unprecedented circumstances.
The project encompasses 68,100 square feet over multiple elevations, featuring a concrete deck, vapor barrier, R25 insulation, cover board, and a 60-mil white fleeceback membrane. The system comes with a 20-year NDL warranty from John’s Manville.

SIGNIA HILTON | ATLANTA, GA
159 Northside Drive
Hotel at Georiga World Congress Center
A stunning, multi-level skyscraper in the heart of Downtown Atlanta! We were honored to serve as the roofing contractor for Skanska USA on the construction of a 950-key hotel, expanding the footprint of the Georgia World Congress Center. This project presented two major challenges:
-
Zero space for mobilization
-
Uncertainty regarding material delivery schedules and fluctuating costs
Despite these obstacles, the project was successfully delivered on time and on budget, even in the midst of unpredictable pricing fluctuations and the complexities of building in a dense urban environment. The project covers approximately 124,000 square feet across multiple elevations, featuring a Sika Sarnafil grey 80-mil PVC roofing system, backed by a 30-year NDL warranty.
03
AT&T BUILDING | ATLANTA, GA
675 W Peachtree Street
Tower & Data Center
This project involved updating the roofing system of the 107,000 SF One Midtown Center 2, also known as the iconic AT&T Building in Midtown Atlanta, with a sky rise height of 600 feet. Also part of the project was the adjacent Midtown Center, an eight-story building housing a data center. The original roof system on the skyscraper needed to be replaced to meet new building codes, including wind uplift requirements.
The logistics were challenging, as materials had to be transported via an elevator that stopped two stories below the roof, requiring custom-built cranes and wheelbarrows to manually move everything to the top. The old roof system contained a coal tar pitch, which emits harmful fumes, so special precautions were taken while transporting materials through the building.
The new roofing system features a 7/16" cement cover board mechanically attached to the deck, followed by a torch-applied APP granular surface barrier membrane. This is layered with two layers of 2", 20-pound high-density ISO insulation, set in low-rise foam. Above this, a 1/2" HD cover board was also installed in low-rise foam. The final top layer is a fully adhered 60 mil TPO membrane.

GEORGIA STATE | ATLANTA, GA
33 Gilmer Street
Sparks Hall
This project involved re-roofing a 38,800 square foot in-town facility with complex exterior challenges, as an adjacent building was being imploded during the process. The scope included a full tear-off of the existing built-up roof (BUR) and modified roof systems down to the concrete deck. The new roofing system featured a torch-applied vapor barrier in select areas, tapered insulation set in low-rise foam, an attached cover board, and a torch-applied barrier. A fleeceback PVC membrane was installed using low-rise foam attachment, providing a 20-year NDL warranty from JM.
What made this project particularly challenging was the demolition of the neighboring Kell Hall, which occurred simultaneously with the re-roofing. This created significant dirt and dust exposure to the new roof system, requiring extensive coordination with both the university and the demolition contractors to ensure the project was successfully completed. The entire re-roofing process was handled by our in-house crew.
05
CAMPBELL MIDDLE | SMYRNA, GA
3295 Atlanta Road SE
Cobb County Middle School
The 717,000 SF re-roofing project involved a complete tear-off of the existing asphalt-based roof systems, which included multiple layers, down to the gypsum or lightweight concrete decks. The new roofing system features an R25 insulation value, a 5/8" cement cover board, and a two-ply, torch-applied Energy Star system, backed by a 20-year NDL warranty from Derbigum.
The entire project was completed by our in-house crews. The complexity of this project stemmed from the numerous alterations and modifications required on the existing building, including deck repairs and replacements, expansion joint work, underground piping, and fascia repairs, all of which had to be addressed within a tight timeframe.
