Office + Mixed Use


Comcast Technology Center


To ensure Philadelphia’s newest skyline-changing skyscraper stood out in every way, Foster + Partners and Gensler Architects envisioned floor-to-ceiling, lobby-to-tower top customization.  Despite the need for advanced engineering systems and data centers, designers kept all elements of the building warm, producing a natural, creative and artistic vibe. The design plan called for a mural on each floor, highlighting Philadelphia’s artist community, and a massive white globe, The Universal Sphere, to make an impressive welcome at the lobby.


For beautiful architectural accents and stunning entranceways, the design team turned to Construction Specialties. GridLine® stainless-steel entrance grids were installed to complement the grandeur of the magnificent steel and glass structure. Beyond the entries, Foster + Partners and Gensler Architects worked with CS to create architectural accents by crafting GridLine+ to cover 24-inch-wide trenches, which act as air diffusers along the curtain wall. Taking full advantage of the high-tech appearance and custom capabilities of GridLine+, the team incorporated 12 grates in the lobby to encompass massive trees as well as grids to surround The Universal Sphere. Additionally, stainless-steel air grille covers were installed in the upper floors of the tower. CS ensured every grid was a perfect fit, even in oddly shaped spaces.
