Protestant Episcopal Cathedral Foundation of the District of Columbia

Washington National Cathedral Structural Repairs

After managing and completing the Cathedral’s stabilization after the 2011 earthquake, APM managed the first phase of the repair process. The repairs entailed interior and exterior restoration involving a series of scaffolds designed to reach the high vaults in the great choir, crossing, nave (which stretches over one-tenth of a mile), transepts, and balconies, in order to cut and repair stones, and to solve water intrusion that caused extensive staining, all while keeping the Cathedral open for programs, services, and visitors. Restoring the Cathedral quake repairs to artistic flourishes like finials, angels, and gargoyles are expected to take years for what was D.C.’s longest-running construction project when initially built.

“In my 37 years of leadership and management experience, the APM team serves as a shining example of “how to do it”.”
– Major General (Ret.) Stephen T. Rippe, USA, Former Executive Vice President and Chief Operating Officer, Protestant Episcopal Cathedral Foundation
