Geotechnical engineering, support of excavation (SOE) design, special inspection services including deep foundation load testing, and review of Site Safety Plans for the new 16-story, 144,000-SF mixed-use building with 175 affordable residential units, a footprint of approximately 15,000 SF, 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.

An exposed rock outcrop was located 3-5’ from the rear of the existing school. Water had infiltrated the joints in the bedrock and subsequent freeze-thaw cycles had caused the joints to open. The orientation of the joints in the bedrock had created a toppling hazard. GTA-NY evaluated the rock conditions and developed plans for a reinforced concrete revetment wall. GTA-NY then oversaw the hand excavation of the bedrock and construction of the concrete revetment wall.
