Located along the banks of the Anacostia River in southeast DC, in an area that was once an annex to the Washington Navy Yard, just one block east of Nationals Stadium, Waterfront Park at The Yards is a six-acre park consisting of extensive heavy reinforced concrete structures, including seawall augmentation over 900 linear feet of architectural concrete overlook retaining wall, 1,200 linear feet of grade beams, 92,000 square feet of reinforced slab on grade, 350 driven precast piles, supporting storm sewers and storm structures, water quality tanks, underground mechanical and electrical room structures, and a custom 200 linear foot span steel and concrete bridge over the seawall.
The park is located in a dense urban environment that is undergoing major redevelopment activities by public and private entities. Careful measures were needed to protect the safety of visitors and staff through temporary protection that separated construction from pedestrian areas through barriers, fences, and signage. A significant portion of the work was performed below grade to include: approximately 350 precast concrete piles to support all structures, fountains and wading pool, sewers, manholes, and the abutments for a 200 foot long steel pedestrian bridge; all new storm and sanitary sewers with associated structures; and concrete ductbanks for electrical distribution throughout the project site.
The underground work was impacted by the amount of obstructions – mainly concrete pile caps and equipment pads – left over from the old facilities that formerly lined the riverfront. In addition the surface work involved most notably a hardscape that included cubic granite lawn steps, granite-clad short walls, granite and precast concrete pavers, extensive landscaping and site furnishings and an extensive boardwalk of Ipe (ironwood) that runs the length of the park along the Anacostia River. The intricate coordination of the pile driving operation together with the underground utilities and concrete structures was a challenge for the contractors given the relatively confined area of the work.
