One Dalton Boston foundation design

Real estate developers

Boston’s tallest residential tower rests on our innovative foundation design system


  • Real estate developer Carpenter & Company aimed to build New England’s tallest, most luxurious residential tower and hotel.
  • But they faced challenges: the design required excavation depths that could cause excessive ground movements, and an adjacent building needed to be protected from damage during construction.
  • A Haley & Aldrich team helped develop a custom, cost-effective foundation design, which included three different foundation types that extended to bedrock and were incorporated with earth support systems.
  • Our team also managed soil and groundwater during construction in accordance with Massachusetts regulations without impacting project schedule.
