Too soon. I was expecting this to happen under some major building downtown and to have to dig a 50+ ft wide access pit through 3rd avenue or something.
@ 10, 12,13 FTW! At least our modern-day tech will allow us to build a decent wall around the city, though. I propose that the Stranger start referring to Bertha as the Boneshaker.
If Dom and the Sloggers were in charge of Obamacare, we'd have dismantled the exchange after the first hiccup and surrendered to the insurance companies.
A tunneling machine that can't tunnel through an obstruction may not be the greatest tunneling machine.
And a tunneling machine that can tunnel through any obstruction would probably be a very expensive tunneling machine.
The tunnel is dumb and a waste of money. But it's also dumb to fault the planners for not going for such overkill that there can't possibly be any difficulty.
Yes, heaven forbid this giant machine not stop once in a while when something unknown is encountered. I mean sure, if it just went full on without concern for what might be found, it would be damaged and you'd complain then as well.
So what the fuck do you guys want? Do you want it done right and the project to respect the fact that not every last cubic yard of earth is perfectly quantified and that when you go digging sometimes you find shit, or do you just want them to ignore all that and risk fucking up the entire project?
Risking "fucking up the entire project" is a little disingenuous, since it was already pretty well fucked from the beginning.
Speaking of which, has anybody figured out how to actually PAY for this monstrosity yet? I keep hearing that King County isn't kicking in any $$ because of access changes, and that estimates for toll revenue keep going down. The Port is willing to cough up a few hundred million to finance some of the SODO improvements, since they'll directly benefit, but otherwise, it still seems like there's a very significant shortage.
@6 if it gets stuck under a major expensive private building that requires something like that, the project dies, unless WSDOT and Seattle want to go to legal war and eminent domain everything in sight, if a strip mine-like digging option is required to rescue Bertha.
@35 http://www.tunneltalk.com/images/Seattle… It'll travel along 1st ave from the Seattle Art Museum up to Stewart/Virginia. They took some care to try to trace it under streets where they could.
@40, no. At 60' below ground, the temperature will be fairly constant, regardless of the surface temperature. In this part of the country, the air temperature above the ground won't have any effect more than about 5' below ground.
@40: Interestingly, maximum frost depth even in North Dakota does not exceed about six feet. Below the frost line, the temperature actually starts to rise, mostly due to radioactive decay in the deeper layers. This is why ground-source heat pumps, using liquid circulated through relatively shallowly buried piping, is a great energy-efficient way to heat AND cool almost anywhere in the U.S.
—But it actually IS like free energy, of course. Your heat pump only consumes kilowatt hours to a) compress the refrigerant [in heat mode, you're refrigerating the ground around the source loop and moving the heat indoors], b) move the transfer medium [usually a water/antifreeze mix] between the ground loop and the heat exchanger, and c) move heated air or water around the house—so it's much cheaper than electrical-resistance heating or burning fossil fuels for heat.
When you're cheering for the project to fail, you'll probably find plenty of opportunity to do so on something of this magnitude and complexity.
I forget, did SLOG go on and on when the construction of the Beacon Hill Transit Station had it's problems and point out what a catastrophe of suckitude that effort was?
Wasn't part of Bertha's dumb stupid expensive thing that she can't drill out of the hole once she's in? So like, if she hits an obstacle, they'll have to dismantle her while she's underground? Wasn't that a thing?
@50 That's generally a feature of every tunneling machine everywhere. Because in addition to digging the tunnel, the machine also places the concrete tunnel lining segments behind it. They must be placed immediately as they serve to support the tunnel and keep it from collapsing, which it would once the boring machine moved on. So placing the lining has to happen, or you can't bore a tunnel.
And the lining reduces the diameter of the tunnel, so the boring machine can't just back up, out of the tunnel. It can only move forward, or not move.
The most disturbing, and quite non-funny thing about all this is that nobody was told about it until an anonymous tipster notified TV and radio stations Sunday night. There was no official announcement from the contractor or WSDOT!
You can be damned sure that with a problem of this magnitude, staff and contractors were working hard over the weekend to determine the scope of the problem and begin finding a way to fix it.
They just didn't bother notifying anyone among the public. What do they matter, they are just there to pay the bills.
You shouldn't even attempt a project like this without a healthy sense of humor. Wisdom is not about what you know, it i about accepting what you do not know and too many engineers can't imagine that there could be anything they don't know.
Too many of us cracker barrel geniuses are always expecting someone else to solve the problem for us and really have no idea what to say!
Or when, like McGinn, did you actually quit trying to stop this thing? At what point should the people have pulled the plug in Boston?
We have a 200' shelter for all of the people that this machine should have been named after, can we seal them in and let them out after they "solve" the problem?
*yawn* Heard it.
@11: It's pretty boring.
I suspect it is in large part "stuck" because they want to identify it before they destroy it.... Though I may very easily be wrong.
Bertha @BerthaDigsSR99
@neiltimes I’m just north of South Jackson Street, about 60 feet below the surface.
There's some happy! happy! info about the tunnel here:
http://www.wsdot.wa.gov/Projects/Viaduct…
but they don't mention anything about whatever this current problem is.

Yeah, but what major private expensive building is on its route?
Halted != Stuck
...but then...
Halted != OK
Nice pun!

Thank you. I had imagined the route to be more waterfrontish.
(Kidding!)
Oh. Hey, there, Dr. Sorry, I..., uh... thought you were someone else.

All to build a cool tunnel for billionaires to their stadiums and private jets.
Told you this was a bad idea.
This could be a blessing.

because nobody wanted to use the EPA..
not even the governor?
