PROJECT OVERVIEW
Phoenix Project #2109
This project called for the installation of 14 drilled helical piles (“HPs”) to support a new gymnasium floor in the MIT W33 Rockwell Gym in Cambridge, MA.
Piles were previously installed to support the perimeter walls of the existing gymnasium structure, but the floor slab was not pile supported. Instead, the floor main floor slabs were poured atop an asphalt layer measuring only a few inches in thickness. Making matters worse, the building did not have any climate control to speak of. This led to excessive settlements along the entrances of the gymnasium, as well as severe deflections in the floors and of the walls of the building.
Phoenix worked inside of the gym to install helical piles to a maximum depth of 25 feet. After a pile analysis was completed, all helical piles were drilled to a installation torque of 1,250 ft-lbs. The piles were reinforced at all installation connections with steel shaft. All piles were successfully installed, cut off, and incorporated into the new foundation.
