How Do You Mend A Broken Monument? Call The 'Difficult Access Team'

At 555 feet above Washington, the work begins.

If you're afraid of heights, this is definitely not your dream job.

Tuesday, five engineers began a series of rappelling operations down the face of the Washington Monument to assess damage caused by the Aug. 23 earthquake that shook the nation's capital. The five belong to a special "difficult access team" from Northbrook, Ill.-based Wiss, Janney, Elstner Associates Inc., or WJE.

"We start to get worried when we realize that we're a little too comfortable," Daniel Lemieux, WJE's site manager at the monument, said Tuesday as he gazed up at the rappelling lines dangling from the tip of the 555-foot-high obelisk.

WJE specializes in difficult jobs and its dozen or so rappelling specialists have experience on other hard-to-access historic structures. But Lemieux, who has rappelling experience, is quick to acknowledge that the company has "never done it on anything quite this iconic."

"It sounds a bit like mixing business and pleasure, but a lot of these engineers doing this kind of work are also interested in rock climbing," he said.

In fact, the equipment being used is no different than you might see an experienced climber using on a sheer rock wall.

Asked whether there's an upper age limit for this kind of work, WJE executive Harry Hunderman laughs.

"There's a point, yeah," he said. "But it has more to do with how comfortable you are doing it."

Each member of the three-man, two-woman team has been certified by the Society of Professional Rope Access Technicians, or SPRAT, Hunderman said. There's no special hazard pay, either.

The company has also worked on structures similar to the monument, such as the slightly taller (and very similar looking) San Jacinto Monument near La Porte, Texas, and Perry's Victory and International Peace Memorial, a 352-foot Doric column at Put-in-Bay on Lake Erie in Ohio.

Two of the five engineers at the Washington Monument have worked on the Put-in-Bay memorial, which commemorates Commodore Oliver Hazard Perry's victory over a British fleet on Lake Erie in 1813. Although not as high as the Washington Monument, in some ways, the Put-in-Bay memorial is more difficult to work on, said Lemieux.

Because of a large, square, viewing platform at the top of the monument, the rappellers come down much further off the face, he said. By contrast, the smooth faces of the Washington Monument are "cleaner and easier," to work off of, he added.

One of the biggest problems is that the original designers of these structures (architect Robert Mills, in the case of the Washington Monument), typically did not plan for future repairs.

"Access was just not part of the thinking process," Hunderman said. "As a consequence, these structures can be very expensive to maintain or repair."

The rappelling procedure works well for assessing the structure, but it isn't very good for anything but the most minor repair. That means that some sort of scaffolding, perhaps an abbreviated version of what surrounded the monument when it was repaired in 1999 and 2000, will have to be put in place for this work, Lemieux said.

But for the next few days, the team will be taking notes and deciding how to proceed. That will likely mean something temporary to keep more water from getting in and damaging the steel structures inside, or possibly lead to a freeze-thaw cycle over the winter that could cause additional damage.

"First we have to figure out the extent of damage and then go through our findings. That's when we'll come up with whatever temporary fixes we need to make," Lemieux said.
