West Point Military Academy required a comprehensive structural assessment and exterior envelope renovation of the following buildings: Building 639, Water Treatment Plant, Scott Barracks, Eisenhower Barracks, The Fire House, and the Library Building. O&S Associates performed inspections and structural evaluation of the building’s exterior façade, roofs, and developed a repair program.
