Curtain wall installation continues at Diller Scofidio + Renfro and Gensler's 14-story building for the Columbia University Medical College. Most of the panels are up on the west façade, where the first panels appeared late last year. More of the non-uniform structural beams, clad in a white shell, are also apparent on the west façade. The cladding of the east façade has started as well, with fully opaque panels at the base that transition in a gradient to fully transparent panels at the southern end. While structurally fully formed in concrete, the "Study Cascade" still awaits its enclosure, which will be a crucial detail that determines how successfully the constructed building achieves the powerful concept in the renderings.
