Charter School Revetment Wall, Bronx, NY

  • 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.
