Foundation Conditions in Boston
Boston's foundation engineering is dominated by the Boston Blue Clay — a sensitive marine clay deposited after the last glaciation that is notoriously compressible and difficult to work with. Much of downtown Boston, Back Bay, and the Seaport District is built on fill placed over former tidal flats in the 1800s, creating a layered profile of fill over organic deposits over Boston Blue Clay over glacial till over bedrock. The city's timber pile foundations (estimated 30,000+ buildings) are vulnerable to decay if groundwater drops below pile tops, creating a unique preservation challenge. The Seaport District's rapid development has driven massive deep foundation programs in recent years.
