One Dalton Street

Boston, United States of America

At 61 stories and over 740 ft., Four Seasons Hotel & Private Residences’ One Dalton Street project in Boston, MA will become the city’s tallest residential building when complete. Designed by world-renowned architect Henry N. Cobb, the all-glass tower is shaped as an equilateral triangle with rounded bays and floor-to-ceiling windows that feature wrapping views of the Back Bay skyline, the Charles River, Fenway Park, the South End neighborhood and beyond to Boston Harbor and the Blue Hills.

The Challenge:

  • 4-day cycle for advancing
  • Restricted movement of shoring material throughout building due to shear wall construction
  • Shear Wall construction restricts movement of shoring material through building
  • Limited spaced on ground for staging and storage of material
  • 10-foot deep transfer slab suspended 39 feet above floor

The solution:

  • Preassembled units unfold and pin together onsite for quick assembly and installation onsite
  • Full perimeter protection at working level
  • 16 foot projection from building to allow for large shoring tables to be easily cycled
  • Windscreen platforms at slab working level which allows the shoring material to be rolled out onto working platform without use of crane.
  • Stored wall forms one floor below working level to reduce crane time
  • 7 fully loaded windscreens that are able to climb in a single lift
  • Fast core and shear wall cycling with Framax stripping corner and quick clamps
