Bronx Borough, NY
GTA provided geotechnical engineering, support of excavation (SOE) design, special inspection services, deep foundation load testing, and review of Site Safety Plans for the new 16-story, 144,000-SF mixed-use apartment building with a footprint of approximately 15,000 SF. The structure includes a total of 175 supportive and affordable housing units, 7,000-SF of first floor retail, and partial cellar level 10 feet below the sidewalk level. The building is supported by a combination of footings bearing on rock and 180-ton caisson piles socketed into the highly weathered rock.
While the building is conveniently located adjacent to a New York City Transit elevated railway station, its proximity to the rail line’s foundations provided a challenge that was overcome by GTA’s engineers during their design of the excavation support.
