Initially, BVH/WJE conducted an extensive condition survey and investigation of the limestone masonry exterior, tower façade, tower window systems, gold tile dome, tile murals, roofs, and roof plazas. An extensive mapping of the deteriorated surface, mortar/stone analysis and window air infiltration testing was also performed. A condition survey report and multi-phase preservation plan were prepared and included the historical background of the construction, repairs and maintenance of the Capitol; an assessment of the existing conditions, including drawings and photographs; and prioritized recommendations for the maintenance and repair of the Capitol exterior, including a cyclical maintenance plan.
