The project included the demolition of the existing timber apron and removal of the associated creosote-treated supporting piles. It was the last section of Pier 91 to be rebuilt because of its complex location. The new dock is comprised of concrete piles, sheet piles, a new bulkhead, battered steel pipe piling, augercast piles and micropiles, concrete caps, concrete decking, steel fender piling and a fender system. Additional riprap, rat rock and other capping materials were added below the apron slope cover.

ORA was engaged to provide testing and inspection services for the following items:
  • Soils compaction
  • Augercast piles
  • Reinforced concrete
  • Structural steel embedded items in concrete
