Charter School Revetment Wall

About

GTA provided geotechnical engineering services for an existing Charter School in the Bronx, New York. GTA was called into the site to evaluate an exposed rock outcrop which was located roughly 3 to 5 feet from the rear of the 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 which prevented the use of several classrooms in the adjacent area of the school. GTA evaluated the rock conditions and developed plans for a reinforced concrete revetment wall. GTA assisted the client in finding a contractor to perform the work, and during the construction phase, GTA oversaw the hand excavation of the bedrock and construction of the concrete revetment wall.
