It looks like Pelli Clarke Pelli’s Transbay Transit Center, which stretches about three blocks through the city’s Rincon Hill neighborhood, might go ahead with its first major piece of value engineering. According to the San Francisco Chronicle, the architects have suggested that the building’s undulating glass skin become perforated aluminum. The move would meet federal safety guidelines and chop $17 million from the estimated $1.59 billion budget for the center’s first phase. The Transbay Joint Powers Authority (TJPA) board will be asked to approve the change at its March 25 meeting. The structure is not expected to be complete before 2017.
As the San Francisco Chronicle‘s urban design critic for the last decade, John King is one of the Bay Area’s most influential champions of good architecture. He chronicles the city’s projects, both large and small, with an eye to how they how they affect the city. (Most recently, he sounded the alarm about how the America’s Cup, with its proposed yacht dock, could change the waterfront for the worse.) His new book of short essays, Cityscapes (Heyday, 2011, $14.95), is based on his weekly column of the same name.
