The COE accomplished this project via the design-build delivery method. The main barrier consists of 1,271 concrete piles 66 inches (1.7 m) across and 144 feet (44 m) long, weighing 96 tonnes each. Behind those piles, steel piles are driven at an angle of 2 horizontal to 3 vertical. The
356:
steel piles are 288 feet long and are installed in two sections, with the lower 158-foot section driven and the upper 130-foot section fitted on top and welded in place. A precast concrete pile cap is placed on top of the steel batter piles and concrete plumb piles to join them.
