WASHINGTON — Engineers harnessed to ropes began a daredevil exterior inspection of the Washington Monument on Wednesday that will include them rappelling down the obelisk to look for damage from last month’s earthquake.
The team of two men and two women climbed through windows of the monument’s observation deck and a hatch near the top to start their work just after noon. They were taking a close look at the uppermost portion of the 555-foot monument, called the pyramidon, before rappelling down to have a look at the rest. The top is where there’s a large crack and where they’re expecting to find the most damage.
The team plans to climb up and down the monument to check each stone for cracks, chips and other damage caused by the 5.8-magnitude quake that shook the nation’s capital Aug. 23. They will take breaks as needed by making a descent that can take 12 to 15 minutes without stops, and resume work by riding the elevator back to the top.
Each team member is carrying several items, including a digital camera, an iPad that includes data from the 1999 restoration of the monument, a two-way radio, masonry tools that will allow them to remove loose pieces of stone or mortar and a soft mallet for audio testing.
Deb Blanchard drove to Washington on Wednesday morning from her home in Palmyra, Penn., to watch her brother, Erik Sohn, scale the face of the monument. Blanchard said she was nervous watching Sohn emerge from the window.
“This doesn’t make me feel very good right now. I’ve got to be honest about that. Wow,” said the 39-year-old Blanchard, adding that her brother wasn’t nervous.
“He’s a very responsible, meticulous, careful kind of person. This fits his personality,” Blanchard said. “It’s such a fantastic opportunity for him.”
Sohn is part of a team from a private firm that’s certified with a rare combination of climbing and engineering skills.
They are in frequent contact with the National Weather Service and will suspend work on the monument’s exterior if there’s a chance of lightning or heavy winds. The weather was calm and mostly cloudy late Wednesday morning after an earlier thunderstorm and showers.
The inspection of the monument’s exterior was delayed a day because of lightning. A team worked for several hours Tuesday setting up equipment and creating a protective barrier around the monument’s lightning rods.
The inspection is expected to last several days and the team has not ruled out working over the weekend.
