The US Naval Academy was in the process of adding a second story to the Terwilliger Center which is located next to the football field. Weak soils required a deep foundation to support the column footings. Helical piles were selected since they were vibration free and could achieve the load without damaging the existing building.

Project Summary:

  • Helical Pile Type: 2875.203 Pipe Material
  • # of Helical Piles: 133
  • Location: Annapolis, MD
  • Installation Depth: 65-80 Feet
  • Ultimate Pile Capacity: 70 KIPS
  • Challenge/Unique Aspect: All the work on this project needed to be done inside an existing building. Small ,non-intrusive, no-vibation, equipment was required and 5′ or 7′ pile segments to deal with overhead restrictions.
  • General Contractor: Manhattan Construction
