Footage of engineers from the Difficult Access Team from Wiss, Janney, Elstner Associates performing the exterior assessment of damage to the Washington Monument in October of 2011.
On August 23, 2011, a magnitude 5.8 earthquake damaged the exterior and interior of the Washington Monument, with the heaviest damage in the Pyramidion (pointy top), between elevations 475 feet and 530 feet. The damage includes cracks of up to 1 inch thick the full height of several marble panels, chips in the panels, missing mortar, components of the lightning protection system have been displaced, and the elevator counter weight frame was damaged. The National Park Service expects to award a contract to repair the monument by this August; work is expected to take 10-12 months. This video was taken in November 2011 during some interim repairs to the monument.
