One Dalton foundation wall complete, elevator core construction underway
Treviicos has completed One Dalton’s slurry wall, which has been fully excavated by The Welch Corporation. One Dalton’s foundation wall is fully built; a slurry wall is in place along Belvidere and Dalton Streets, and secant piles are in place along the Christian Science Center. The foundation cap beam, which holds the top of the foundation wall together, has been installed. Both the slurry wall and secant piles tie into bedrock over 150 feet below the building.
The 61-story elevator core is now being built. Metal formwork is being arranged at the foundation’s base to frame the concrete pour to construct the core. A 7 foot thick, 900 cubic yard wide concrete mat slab is now being poured at the core’s base. The following are photographs of the One Dalton construction site:
