West Point Military Academy
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. O&S prepared repair drawings and technical specifications and made periodic observations of construction as part of construction management services.
The restoration of the buildings’ repairs was comprised of replacing the existing roofing with new cold-applied, built-up roofing, renovation of all exterior brick and stone façade elements, reconstruction of cracked and bulged brick masonry parapet wall, replacement of cracked and spalled brick masonry, removal and reinstallation of coping stones with new cap flashing, tuck pointing of brick and stone masonry, and installation of new windows, window sealants, and application of new surface sealer for the entire façade. Total cost of restoration was $14.2 million. O&S was selected to study the exterior envelope of several buildings at the West Point Military Academy and develop a repair program for a multi-year renovation project. The renovation project started in 2006 and completed in 2009.
The existing roofing system at each building was deteriorated and leaking in multiple areas. All six buildings required a new roofing system. The total size of the roofs was approximately 800,000 square feet. The existing brick façade of building 639 needed extensive reconstruction. The water treatment plant, Eisenhower barracks, Scott barracks, and library building had ornate stone facade, cornices, and copings stones that needed careful design and construction.
