The Today Show
Earthquake Damage Repairs Contract: Grunley was a subcontractor to Perini Management Services, Inc. to repair damage to the Washington Monument sustained in the August 2011 earthquake. The scope of work included removing and/or securing loose stone fragments, stone patching, repairing cracks, re-pointing and replacing the lightning protection system. The same scaffold system used for the repairs in 1999 were erected for the earthquake repairs. While the scaffolding was up, it was adorned with horizontal and vertical mesh that was backlit at night. This project received a 2014 Craftsmanship Award for exterior stone and marble from the Washington Building Congress.
Stabilization/Preservation Contract: More than ten years ago, under a separate contract, Grunley and our joint venture partner, stabilized and preserved the Washington Monument. The scope of work included stone and crack repairs, as well as re-pointing and cleaning the entire monument. The most notable aspect was the aluminum scaffold erected for the work that mimicked the profile of the monument. It was decorated in horizontal and vertical mesh to provide a block and joint appearance. The monument was also backlit inside the scaffold to provide a glowing effect. This was a prominent display for the millennial celebration in Washington, DC.
