September 29, 2011 Washington Monument Engineers
On August 23, an earthquake hit the Mid-Atlantic region. It was fairly big by East Coast standards, and it caused moderate damage to the Washington Monument. The Monument is basically just a bunch of blocks stacked on top of one another, reaching 555 feet high, and is not really designed to withstand earthquakes. It has been closed since the earthquake for safety reasons and a perimeter around the base is now fenced off.
The National Park Service is hoping to re-open the monument one day, but first it must inspect each and every block and joint on the exterior. The mortar between the stone blocks is relatively soft compared to the blocks themselves and much of the mortar between the joints fell out during the quake. With winter coming, the worry is that water will get into the damaged joints, freeze, and damage the blocks even more.
Enter the "difficult access team" from engineering firm Wiss, Janney, Elstner Associates. These 4 engineers, hired by the NPS, are repelling down each face of the monument, cataloging the damage and doing emergency weatherization.
I just had to take a walk over there on my lunch hour and snap some pictures. There were around 100 people doing the same thing.
We need to zoom out a little for some perspective.
Here you can see one of the engineers actually working on the joint under a broken marble block.
Nicely done sir!
"We've secretly replaced George's safety harness with new Folger's Crystals... let's see what he thinks!"
those blocks look like they're the same proportions as a domino, a large rectangle, relatively thin for its area.
Yeah, it's pretty amazing none of them fell off during the quake. I guess they are wedged in there pretty tight.
I really could have used a pair of binoculars, but one thing I could see was that each one of these guys had a bucket clipped to them. I think they were removing loose mortar chunks and putting them in their bucket to bring them inside and down the stairs rather than drop them to the sidewalk below.
Also, they had dropped ropes down the sides of the monument, but for some of them, the ropes didn't reach the ground and were a good 50 feet from the ground. Not much use. Although now that I think of it, the ropes were also looped inside the windows just below them, so maybe there was enough slack there to account for reaching the ground.
You know, I've never really paid attention. What's the Washington Monument used for? Is that how we communicate with the space aliens?
No capital city is complete without a generous supply of giant dicks.
Wow! Great pics!
My first impression was "Cool, we have our own pyramid."
Then I wondered how in the world they got the ropes on the top of the point. That was some lassoing job!
There was a short article in the paper this morning. Some interesting tidbits:
-of the 4 engineers, there were 2 men and 2 women
-they carried iPads containing all the relevant data from the big renovation done about a decade ago
-they carried digital cameras to document everything, (and I saw them taking each other's pictures.)
-they carried rubber mallets for tapping on each block to listen for any hollow sounds that might indicate hidden cracks
-they also had a small collection of trowels and other masonry tools
I wouldn't do that job for all the money in the world.
It's making my flesh creep just looking.
Fascinating though. Great thread, Glatt.

Me neither. Can you walk inside anything?

I would. If I'd been born with gumption and mettle, I could've pursued such a career. I love heights, I love thrilly stuff, I'm fearless, I have good eye/hand coordination. :p:
I bet they make beaucoup bucks, too.
Good job! I can't remember an IOTD actually generated by an IOTD'er.
I've been there and wore myself out walking DOWN the stairs.
"Not really designed to withstand earthquakes." What an understatement.
I'm amazed it did, but there has to be more than just "stacking" involved.

I could hardly stand the inside of the Capitol dome. I can't imagine the outside of the Monument.

I had real trouble going up to the dome in St Peter's (Rome).
I felt claustrophobic and I knew the only relief would be when I came out - but that would be high, high above the city...
Ditto the bell tower in Siena.
Something about Italian cities makes me feel the need to punish myself! I think it's because I can't face going home and giving the shameful response, "No. I was too scared."

I miss SV :(
I prefer our current Chi owners. :thumbsup:
There was also one taken by seakdivers a long time ago, I think. Can't remember what it was; something in the water in Alaska, presumably.
Ohhhhhhh...Hua Hua!
I didn't know the old chi owner but I like the current one too. ;)
I just saw I've been Boing Boigned. I submitted some Flickr shots to their pool and they put one on their front page. Cool!
4 guys going down on a giant phallic symbol. Been there; done that.
:D

I climbed the Leaning Tower of Pizza in 1988. I think they closed it to tourists not long after that. I took some pictures looking down at my bicycle, but I don't know where they are now.

It was still open in 89 when I did it..... it was kinda scary because the floor was so polished! I don't mind heights as long as I feel secure up there
congrats on your boinging, Glatt. and Sheldon.

I guess I didn't actually state that I had taken them.
Hang on, of three (known) IotDs that were taken by dwellars, we have one actual giant penis, one model giant penis and one symbolic giant penis.
Are we teh gay?
For you guys who wonder about the inside here's a movie of the quake on a security camera at the top of the stairs. It's worth the watch.

What do you think the guy in the white hat came back up for?

Two guys two gals. Something you are trying to tell us, Sheldon?

Am I teh gay for liking the occasional penis?
Off to get a rainbow tattoo then...
More than three shakes is masturbation.

Never more true than in Provincetown, Massachusetts!

This one wasn't a penis. Although he is a bit of a dickhead sometimes.....
http://cellar.org/showthread.php?t=17822Let me just say that
David M. Rubenstein is the man.
This billionaire philanthropist is giving $7.5 million to pay for the Monument's restoration. Congress is paying the other $7.5M, but was looking for private donors to match the government's contribution.
Mr. Rubenstein has previously given millions of dollars in gifts to the federal government for stuff in the DC area. He just gave $4.5 million to the zoo's panda program. He gave $13 million to the National Archives to pay for a visitor center and a special display area for a copy of the Magna Carta he bought and lent to the Archives. Before that, he lent a copy of the Declaration of Independence to the State Department, a signed copy of the Emancipation Proclamation to the Oval Office and the first official map of the United States published after the American Revolution to the Library of Congress.
Way to go, rich dude!
The Washington Monument is expected to be closed for at least another year, because they haven't even begun the repairs yet.
I read that earlier. Good for him!
They just need some
Sugru. Well, maybe lots of
Sugru.
Is that like Bondo? :lol:
Did you read the
Sugru story? It's quite inspirational.
I bought a bunch of Sugru to give as stocking-stuffers last Christmas. Unfortunately, since it came from England, and I only bought it with about one month's notice, it got held up in customs or someplace and didn't arrive in time. So I ended up with all this Sugru. I couldn't think of enough ideas to use the stuff on, and since it has a short shelf life, It's probably mostly all gone bad by now. (ETA: It's been a year+)
I did put some on the underside of a picture frame that was just sitting on a shelf, leaning against the wall behind it, and kept slipping and falling over. That worked well. But I didn't have any other ideas. I felt like there was too much pressure to come up with something clever.

It's not the kind of stuff you want to waste on something mundane.
Well, did you see the packaging? They come in these beautiful silver pouches. Once you tear a pouch open, that's it. It starts to set up. You're committed. It better be worth it. :eek:
I used some on a lid for a cast iron pan so I could pick it up without burning my finger, and some on my pellet stove door for the same purpose.
I also used some to mount a mirror to the brake hood on my bike.
I'll probably also use Sugru to fix my cell phone, which has a cracked case, but just won't die.
Sugru looks awesome, I must admit.

Sounds a lot like updoc.
Not much. What's up with you?
Thanks infi.
I can play the straight man from time to time. :D
I snorted out loud when I read your post, btw! 5 words. Snort-worthy!

...and they have a plan.
The report from the engineers is complete and the park service now has a plan.
They're going to cover the monument with scaffolding and set up a tower crane to help remove the 1 ton external marble panels at the pyramidal top and re-attach them with metal brackets because the anchor stones underneath were cracked by the quake. The metal brackets will be hidden from view.
They also need to patch 50 panels, but don't expect to need to replace any of them. The work is going to last into 2014 and the monument will remain closed through then.

Closed the whole time? Just have the visitors run to the entry. They'll have a greater memory of their visits.
I feel like I need to keep this thread updated.
They started erecting the scaffolding. It looks like just regular scaffolding. I'm surprised it's strong enough to reach that high. They have special cross bracing at the corners to tie it all together.

They still have a ways to go.

I wish I had a time lapse camera set up taking a picture every half hour. It would make a cool video.
A lattice condom, very avant gardey.
Don't worry about the scaffold, you can be sure OSHA will be all over that sumbitch.
I notice there seems to be a concentration of damage at around 200 feet high. I wonder why.
Maybe because...
Construction of the monument began in 1848, but was halted from 1854 to 1877, and finally completed in 1884. The hiatus in construction happened because of co-option by the Know Nothing party, a lack of funds, and the intervention of the American Civil War. A difference in shading of the marble, visible approximately 150 feet (46 m) or 27% up, shows where construction was halted. Its original design was by Robert Mills, an architect of the 1840s, but his design was modified significantly when construction resumed.

Too bad this isn't in Hong Kong they'd probably be using bambo!

I like to tell visitors to DC that that's the high-water mark from the flood.

The waves of energy from an earthquake create a "whiplash" effect in buildings, with damage being much more concentrated where the "whip" energy of the earthquake, reverses itself - "cracking".
That was the sort of thing I was thinking, maybe involving some kind of harmonics in the building and the frequency of the earthquake waves.

Monterey Bay: When I was a kid I worked at the Boardwalk on the beach. Tourists from all over the world would show up and often would point across the bay at Big Sur which sort of rises up abruptly from the end of the Monterey peninsula and ask, "what's that?"
I'd always tell them "Hawaii". Many believed me.
welcome back Adak.
Thanks, BigV! :D
