After completing removal of the existing concrete deck and structural steel under separate contract, Advanced American Construction, Inc. (AAC) constructed the new Berth 1 Dock for Schnitzer Steel Industries, Inc. at International Terminals in Portland, Oregon. The high load capacity dock, which supports the client’s scrap metal operations, is a cast-in-place concrete deck supported by structural steel framing on steel pipe piling. Next to the dock is a pile supported cast-in-place concrete relieving platform and a cast-in-place concrete approach slab on grade.
The 40,000 square foot project required: 5,500 cubic yards of structure excavation and 700 tons of rip rap slope protection; 7,500 lineal feet of 24 and 36-inch diameter open-ended steel pipe piles; 540 tons of structural steel framing; 4,500 cubic yards of cast-in-place reinforced concrete; 485 lineal feet of 171# crane rail system with stainless steel cable trough; 29 each, 255 kip tiebacks (for required seismic design loads); 100 tons of miscellaneous metal walkways and fabrications; and 1,000 lineal feet of under-dock utility and drainage piping.
Prior to contracting with the client to build the project, AAC value-engineered certain structural elements—including redesigning the steel pipe piling to a composite (steel pipe filled with reinforced concrete) pile section—resulting in over $400,000 in up-front cost savings to the client.
