LERA was the structural engineer for a new 17,000-sf addition to the Herbert F. Johnson Museum of Art, as well as renovations to the existing 5-story, 60,000-sf facility. Originally designed by I.M. Pei in 1973, the new wing adds a dramatic new sculptural glass-and-concrete entryway and lobby, gallery space, art storage, office space, workshop studios and a 150-seat lecture hall. The site’s sloping topography allows daylight to penetrate down to the gallery level, providing views throughout of a Japanese garden set into the hillside. Linked to the main building on two levels below grade, the addition’s separate entry makes it possible to host events without having to open the museum in its entirety. A 6,000-sf renovation to the 5th Floor expanded gallery space for the Asian art collection by 50%.
