The New York Hall of Science provides a hands-on experience for members of the community to explore science and technology. In an ongoing effort to improve their facilities, the Hall of Science, in collaboration with the New York City Department of Design and Construction and the New York City Department of Cultural Affairs, implemented the second phase expansion of their master plan, featuring an innovative program that utilizes sustainable design to promote energy efficiency.

LERA was the structural engineer for a 70,000-sf (6,500-sm) addition that provides expanded space for permanent and temporary exhibits, as well as exhibition preparation and shop facilities. It features the "Hall of Light," an exposed steel structure that spans a day-lighted 225-ft by 50-ft (69-m by 15-m) exhibit hall. The form of the exposed structure complements the architect’s vision, and encompasses the desired "structure-as-exhibit" motif.

LERA was also the structural engineer for the façade restoration of the existing Great Hall, which was originally constructed for the World’s Fair in 1964. The 100-ft (30.5-m), 1-ft-thick wavy concrete wall is composed of 5,400 concrete coffers cast in a style known as dalle de verre, or "slab of glass," which are each studded with shards of cobalt blue glass. Approximately 35% of the exterior concrete structure was in need of repair, and rebar exposed through cracks showed signs of corrosion and rust. The restoration team specifically selected mortar and aggregate types that would best replicate the concrete color and texture adjacent to areas of repair, and approximately 50 new glass panels were made by the original manufacturer to accurately replace those damaged beyond repair.
