Chesapeake Bay Dock Stair Tower

Eight helical piles were installed to a depth of 20 feet in one day. Their galvanized custom design caps were welded to long pieces of channel steel as part of a new steel structure that clamped to the existing structure.  Further movement was arrested.

Project Summary:

  • Helical Pile Type: 1.5” Square Shaft
  • # of Helical Piles: 8
  • Location: Chesapeake Bay, MD
  • Installation Depth: 20 Feet
  • Equipment Used: Handheld Set up, 6,000 Ft. Lb. drive head
  • Challenge/Unique Aspect: Access was tight working inside the stair tower and required portable hand-held equipment that could get inside so that the stair well did not have to be disassembled to install the new foundation.
  • General Contractor: Keystone Foundations
