Construction of an addition for a residence in Coney Island. Timber piles were speced but limited access and vibration concerns ruled that option out. Instead, helical piles were installed with small equipment mitigating mobilization issues and eliminating vibration concerns.

Project Summary:

  • Helical Pile Type: 1.5″ SS
  • # of Helical Piles: 26
  • Location: Coney Island, NY
  • Installation Depth: 21′
  • Equipment Used: Takahuchi Excavator
  • Challenge/Unique Aspect: Limited access with 12′ width max. Could not get a timber pile rig into small space. Required small equipment with no vibration due to the proximity to neighbors.
