Conceptual scaffolding

Lambert Williams, Ph.D. student in the history of science, is about to be hidden behind canvas-covered scaffolding as he descends the stairs in the Science Center, where extensive renovations are in progress. The Science Center is just one of a range of projects that ramped up over the summer months. In addition to renovations at Lippmann House, the Faculty Club, Widener Library, and other sites, the construction of a new north campus garage and the twin buildings of the Center for Government and International Studies are also underway.
