Ally Charlotte Center caps office tower with branded, custom-engineered SKYSHADE polycarbonate system by EXTECH

What?
Construction of Ally Charlotte Center’s new, contemporary, Class A mixed-use office tower that rises 26 stories and spans 750,000 square feet. Positioned at the gateway to Uptown and at the south End entrance to the burgeoning Stonewall Corridor, it adds a new dimension to the evolving skyline in Charlotte, North Carolina.

Where?    
Charlotte, North Carolina

Who?
EXTECH capped the office tower with branded, illuminated, custom-engineered SKYHEAD polycarbonate system. Little Diversified Architectural Consulting designed the building. Brasfield & Gorrie oversaw the demolition of the former auto repair shop and the construction of the core and shell of the building, as well as the interior build-out for Ally Financial.

What was the goal?
The aim of the construction of this building is to provide convenience as it offers a centralized, collaborative, open plan work environment. Through a phased moved-in process, nearly 2,100 Ally Financial employees will come together from across the city to occupy 400,000 square feet on 23 floors of the tower.

What was done?
Brasfield & Gorrie oversaw demolition of the former auto repair shop and construction of the core and shell of the building, as well as the interior build-out for Ally Financial.

The lighting of the building designed by Little Diversified Architectural Consulting used EXTECH/Exterior Technologies.

EXTECH’s SKYSHADE system and opal-hued polycarbonate panels produced a lantern effect. EXTECH engineered its system with custom outriggers, anchors and pins to display the large Ally logo on the Northwest and Southeast elevations.

Maintaining aesthetic required a high-performance system. The 25-foot-high panels are rigidly framed in metal with supporting vertical, tubular mullions behind the screen wall.

“Wind was a big factor on the top of the skyscraper,” said Jim Leslie, EXTECH’s general manager. “The SKYSHADE 8000 is built with our patented aluminum clamping framing system. SKYSHADE 8000 primarily is used for long-spanning, standing-seam canopy structures. Our unique, patented design offers continuous glazed panel runs up to 54 feet long without leak-prone intermediate horizontal mullions. For Ally Charlotte Center, we essentially re-engineered our high-performance sloped canopy system for a vertical, wall application. Installed on all four sides of the building’s roof, the longest runs span more than 230 feet.

Enhancing the building’s clean, sophisticated look, the polycarbonate panel system also has a practical function; it conceals the rooftop mechanical equipment and lights. EXTECH installed the panels 7 feet from the building’s exterior edge allowing a walkway for maintenance and repairs. EXTECH also engineered doors into its system to facilitate safe access. Throughout their long lifespan, the polycarbonate and metal assemblies require minimal cleaning. If a panel is damaged, the modular system makes it easy to replace. The system’s longevity, low maintenance, recycled and low-VOC content, and recyclable materials also contribute to the project’s sustainability goals.

Once the system design was approved, EXTECH fabricated it at its quality-controlled facility in Pittsburgh. As much as possible was pre-assembled for a precise fit. Corner panels were factory-formed, extruded aluminum edge trim was shop-applied and access doors were shop-fastened for fast, accurate installation at the job site.
