Back in March, a rendering was revealed of Columbia University’s three-story, 55,980-square-foot University Forum and Academic Conference Center at 3205 Broadway, located on a triangular block bound by West 125th and 129th streets and Broadway, in the Manhattanville section of Harlem. At the time, excavation work was underway at the site, but now foundation work has commenced, Harlem+Bespoke reports. The structure will feature a café, an information center, offices and meeting rooms, and two auditoriums. The building is the part of the Columbia’s greater Manhattanville campus, which, when fully built out, will span 17 acres and roughly a dozen buildings. Renzo Piano Building Workshop is the design architect and Dattner Architects is the architect of record. Completion is expected in 2018.
