Description: As part of M.I.T.'s redevelopment plans in Cambridge, two existing concrete framed buildings built in 1910 were partially demolished and renovated. A four level underground garage, 46' in depth, was constructed within 18" of the partially demolished building. As a result, an up down construction sequence was used to minimize ground movement during construction. Twenty four interior LBEs with permanent embedded garage support columns were constructed and founded in very dense glacial outwash.
