The New York Hall of Science was established as part of the 1964 World’s Fair and is one of the few extant structures in Flushing Meadow-Corona Park. Designed by Wallace K. Harrison (Harrison and Abramowitz), the Hall of Science is distinguished by its serpentine plan. The 80-foot-high walls are a curved reinforced concrete grid comprised of horizontal and vertical flat concrete bands creating approximately 5,400 cells. Each of the cells is filled by cobalt blue glass polygons of varying shapes and sizes embedded into cast stone panels. BCA carried out extensive testing during the pre-construction phase to determine the appropriate restoration treatment of the concrete wall system. BCA wrote documents for the restoration, assisted with the bid phase to find highly qualified contractors to carry out the work. During construction BCA provided inspection services to ensure all of the work was carried out as specified by our documents. The project received a lot of attention for its approach to concrete conservation and was featured in the Getty Conservation Institute publication, "Concrete: Case Studies in Conservation Practice", The Association for Preservation Technology International Journal, "Restoration of the Cast-in-Place-Concrete of the New York Hall of Science", and a chapter of the book Meet Me at the Fair featuring the hall's restoration.
