Brooklyn Basin

SGH designed the structure and foundation for all waterfront structures and also developed a complete coastal shoreline protection plan. Highlights of our work include the following:

• Performed a detailed inspection of deteriorated piles under the 9th Avenue Wharf, constructed in the 1930s
• Evaluated the capacity of more than 2,000 piles, designed repairs, and prioritized the repairs
• Evaluated the existing wharf structure for anticipated seismic, mooring, and berthing loads
• Designed a seismic retrofit for the existing 1,300 ft by 80 ft wharf and various structures above the wharf deck and performed three-dimensional nonlinear finite element analyses to verify the design approach
• Collaborated with the geotechnical engineer to develop and finalize a cost-effective toe wall design to stabilize the rock dike slope for the maximum design earthquake
• Prepared demolition plans and specifications for partially removing numerous existing structures at the project site
• Designed two new pier structures and a 200 ft long, pile-supported ramp structure over the water in Shoreline Park
• Developed a structural rehabilitation program for an existing 200 ft long access bridge near the wharf
• Designed retaining walls, wharves, docks, bulkheads, and outfall structures
• Performed wind and wave load analyses and designed coastal protection along more than 6,000 ft of shoreline
• Designed storm drains and other utilities
