Recognized for its innovative use of structural steel, an office addition and renovation completed by T.G. Nickel & Associates received a 2016 IDEAS2 National Award by the American Institute of Steel Construction (AISC). Designed by Marvel Architects and completed in 2014, the American Physical Society (APS) Editorial Offices in Ridge, NY features an 18,000 square feet second-story expansion.
APS is a non-profit organization founded in 1899 to “advance and diffuse the knowledge of physics”. Because the Long Island Pine Barrens Preservation Act prohibited expanding the building’s footprint, the expansion took place above the existing 30,000 square feet structure.
But that presented one small issue because the existing structure – footings, columns, roof framing and lateral system – could not support the new second story. And so a long-span design with a column grid was used resulting in minimal penetrations through the existing ground floor – only six columns penetrate the interior of the existing building and the new second floor is elevated four feet above the existing roof. The “bridge” over the existing structure also allowed the new steel to be installed without causing any disruptions, which was critically important because APS’s headquarters remained open and operational for its 150 employees throughout the entire project.
According to AISC, the APS addition and renovation was “an honest project that celebrates the existing building and steel expansion structure without overwhelming you.”
