• No More Cracks

    Innovative solution to prevent settlement of upland facilities.

  • Built to Last

    The wall section is protected by a cathodic protection system to meet the design life goals of 50 years.

Without interruption. The Navy’s existing 650-foot corrugated sheet pile wall was damaged and needed to be replaced to protect soil slope stability and adjacent waterfront upland facilities. Reid Middleton provided design services for replacement of the existing sheet pile cutoff wall with a new wall system that combines king and flat-sheet piles. The timber-fender piling system was replaced with the new environmentally-friendly, reinforced plastic-fender piling system made of recycled high density polyethylene (HDPE) and crack and spall repairs were made to the concrete wharf structure. The innovative solution of driving straight-sheet and wide-flange king piles in limited space behind the existing damaged corrugated sheet pile wall was developed to improve soil stability and prevent settlement of adjacent buildings and utility trenches. The Navy’s 24 hours a day, 365 days a year operations were not impacted due to the innovative design and effective project management provided by the design-build team.
