UA Local Union 524 Building Addition


Date: 8/1/2019


An addition was being added to the training facility of a local union hall in Scranton Pennsylvania. Concrete underpinning was part of the excavation process. The engineer of record specified helical tiebacks for the underpinning pits.

Project Summary:

  • Helical Pile Type: 1.75″ Square Shaft 8,10 Helix Configuration
  • # of Helical Piles: 11
  • Location: Scranton, PA
  • Installation Depth: 18′
  • Ultimate Pile Capacity: 20 kips
  • Equipment Used: Cat 305, 12K drive, Marian Torque Indicator
  • Challenge/Unique Aspect: IDEAL helical piles have a standard “sea shell” cut on their helix plates and generate more torque than many comparable competitive products. This was a major help in penetrating the dense, cobbled soils on the site. This in turn helped to keep the project on schedule.
  • Engineer/Architect: E.D PONS
