Project Description

Advanced American Construction, Inc. (AAC) utilized its considerable underwater construction and diving experience to successfully build the T-6, Berth Deepening and Scour Protection project for the Port of Portland in Portland, OR. AAC in-house diving and surveying personnel played a key role in the timely success of this technically challenging project. The 440 lineal-feet of underwater sheetpile wall between the edge of the dock and the existing fender system required: 110 pairs of 60-foot-long AZ25 sheetpiles driven to a top elevation 50 feet +/- below the water surface using both vibratory and impact methods; 1,000 cubic yards of 4-inch-minus and 12-inch-minus rock fill and armor rock placed underwater; relocation and replacement of the existing fender system to facilitate installation of sheetpile to tight location and elevation tolerances; and continuous coordination with Port personnel to safely and efficiently work around ship schedules. AAC took advantage of its experience at the Port of Portland’s T-4 Berths 410 and 411 project to get ahead on the planning and construction of this very similar project.
