What’s blocking Bertha: a long steel pipe
Seattle Times ^ | 1/3/2014 | Mike Lindblom

A buried steel pipe is mostly to blame for stopping the giant tunnel-boring machine Bertha, which has been stuck since Dec. 6 along the Seattle waterfront near South Main Street.

The long pipe was an 8-inch diameter, 115-foot-long “well casing,” used to measure groundwater during studies in 2002 on the Alaskan Way Viaduct replacement project, project officials said.

Matt Preedy, the deputy project administrator for the state Department of Transportation, said he had no estimates about how much time and money is will take to remove the rest of the pipe, and to repair damaged cutting tools on the face of the machine.

Nor does the team have a strategy yet for how removal should take place. One possible method is to send tunnel-trained divers to work near the cutter face, under extreme pressures that are exerted by groundwater.

Supposedly, the description and location of the pipe was contained in the planning documents before the machine was started... the WSDOT rep was doing a lot of stuttering during the news conference!

Someone is an idiot. Likely the contractor and the state DOT.

“I don’t want people to say WSDOT didn’t know where its own pipe was, because it did..."

That's why they've been trying to figure out what's blocking the boring machine since December 11 (more than three weeks ago).

Another day, another insult to my intelligence.

They will probably pull the machine out, fill it full of religious statues and items, put it dim lights, and end up calling it “The Christine Gregoire Memorial Grotto” or some such...

I figure building a tunnel like that in Seattle makes about as much sense as building nuclear reactors right on a fault line in Fukushima...

Seems someone could have walked the surface directly above and found that out in at worst an hour or two. There’s gonna be a grout plug there...

An underground tunnel, 55 feet in diameter, 1.7 miles long, that is set to replace an elevated roadway here called The Alaskan Way Viaduct.

They want to tear that down due to earthquake concerns.

They say the hundreds of millions of dollars worth of waterfront condos they could build have nothing to do with the decision.

I believe they said (yesterday) that they had been drilling a series of holes to a depth of more than 100' in order to try to make contact with the pipe they "knew was there."

Here's the link.

Looks like about 5 minutes after the thing quit making progress, the operator would have backed the silly thing up and looked to see what it was hitting. They should have been able to see a bunch of shiny steel. Get some guy with a torch and be operational in a few hours max.

Exactly. They claim they knew the pipe was there all along yet left everybody stammering since December 6 about the possible cause. Yeah, they knew all along, they were just laughing and playing to see when everybody would figure out this funny trick.

This sounds exactly how Obama and Liberals respond - a big fat lie.

As a bypass of downtown Seattle this project is fine. For commuters trying to get into downtown it is going to make for a longer commute.

Why?

Because a lot of traffic gets into downtown via the SR 99 viaduct using the Seneca Street and Western Ave exits.

Think traffic is bad now? It’s only going to get worse.

So what happens if you are in your car in the underground tunnel when an earthquake hits?

I lived on an island with a view of Seattle when the tunnel -skyway-widened street debate went on. Some of us could actually predict the junk a tunnel would run into, the delays, they astronomical endless costs. Was anyone listening?

Pipe smipe. It’s the secret headquarters of the Borg’s earth colony command. They program obammy ‘s TelePrompTer from down under there ( with a not- a-little help from Satan and Soros and the Muslim brotherhood). All paid for with newly- printed “ stimulus funds”.

Wonder if the guy in charge of installing this pipe (in 2002) died, so NO ONE now remembers when/where it was installed. Huh?

I'd say, "unbelievable" but this is government. Given there was speculation during the last couple of weeks that it might be a mid-1800's locomotive or other trash from over a hundred years ago, having this obstruction put in, and then a mystery, ELEVEN years ago is crazy. Maybe someone should give the DOT an Excel spreadsheet program so they might now keep track of what they bury and where.
As I said, unbelievable.

I headed a tunnel boring machine manufacturer in Seattle in the 80’s & 90’s that did the Chunnel between France & UK. Much more difficult tunneling problem in the French side. (you can see a video of it on youtube.

Most TBMS have the capability to bore small holes ahead if you run into obstructions. Go forward until against the object, Then go in pressurize the head, gunite the walls forward, then, manually go in and dismantle the pipe. If done properly could be done in a week.

In an EQ the tunnel lining most likely crack, and fill with water, (maybe they are using a double walled system?)

If they made the area under to old highway into a park area like Portland did next to the Willamette, it would be a real Tourist attraction.

I’ve lived in places with tunnels. Traffic invariably backs up at the tunnels for no good reason. Good luck with that.

But the pipe (casing) is going to be vertical and I can't imagine that as merely a test well or piezometer it would be more that 30 inches in diameter.

Additionally, I find it hard to believe they would have put any holes in the ground without GPSing the location. I GPS everything unless Caltrans has specifically given me coordinates they have previously generated for whatever I am sticking a hole in...

Well, starting with the Mark XXIII Continental Siege Units, dual Hellbores were standard, but neither barrel would extend past the Duralloy Hull, which is what is probably what stopped the TBM's cutters. As long as the activity does not trigger the psychotronic battle reflex circuits, the tunneling crew should be OK.

BOLO

Heh. Like I guessed last night:

“holes at 5-foot spacings - and they didn’t hit anything! Curiouser and curiouser. Perhaps it IS a vertical pile or something?”

Although I was thinking more of some unknown pile or pipe. Not the kind where you go down to the planning office and they say “Oh. We were wondering when you were going to ask us about Well No. 76028!”
