Boston Harbor's original shoreline crossed this 3 acre site until it was filled in starting in the 1850s. The earliest structure on the site was Urann's Wharf, which held the city stables. Two residential midrise towers were constructed on this block long city parcel, within a single deep foundation. A reinforced slurry wall, braced with a single level of internal cross lot bracing was chosen as the temporary earth support system due to a potentially unstable layer of fill and organic soils, thirty feet in depth. Slurry wall panel excavation proceeded with caution to ensure there would be no unexpected ground loss during wall construction.
