2018/10/10 - Washington National Cathedral Site Visit

- Josh Jaskowiak 

 On October 10, members of SEA joined Joe Alfonso, James Shepherd, and Travis Green at Washington National Cathedral for a discussion of earthquake repair efforts.  Following the 2011 Mineral Earthquake, a multidisciplinary team has been working together to access damage sustained during the seismic event and implement repair strategies to the various pinnacles, towers, buttresses, and masonry features that compose the Cathedral’s distinguished façade.  In their roles as Head Stonemason Director of Preservation and Facilities, respectively, Joe and James are responsible for the care and preservation of the cathedral’s long and storied built history and gave our SEA members a behinds-the-scenes look at the Cathedral’s care.  Representing Wiss, Janney, Elstner Associates, Inc., Travis Green co-presented on the various challenges encountered during the repair project and solutions implemented.  The presentation culminated with a walking tour of the apse parapet and a picturesque view of Washington D.C. at sunset. 

An insightful and memorable time was had by all.  SEA is thankful to Joe, James, and Washington National Cathedral for opening their doors to SEA and sharing their love of their one-of-a-kind home of living stones. 


Joe, James, and Travis present a timeline of assessment efforts immediately after the 2011 Mineral Earthquake.






Joe presents fragments of stone recovered during the repair efforts.








Joe and James lead SEA members of a tour of the apse parapet with an up-close view of the pinnacles and buttresses on the Cathedral’s south elevation.  The apse represents the oldest part of the Cathedral and features masonry craftsmanship over 100 years old.
