What happened next was something neither Jim nor Paul witnessed, but which they heard about from a mechanic and one other worker present at the time. Since Bertha was the largest TBM ever built, says Jim, “it’s not surprising that we had to deal with some bugs, some electrical issues that had to be worked out.” Another issue was that everybody working on Bertha developed “a sniffly nose” and a lot of people were getting sick, said Paul. Awhile back they were saying it had nothing to do with it but it brought to mind how that project is looked to people outside of Seattle. After four years underground, Bertha reaches daylight. Repairs led to a two-year delay in the $3.2 billion project. He is digging a test trench outside the HQ of his company SpaceX in Los Angeles, and while he admits "We have no idea what we're doing," he says he hopes to increase the speed of tunneling by 500 to 1,000 percent. New photos capture massive scale of Seattle tunnel project as Bertha creeps along by Kurt Schlosser on March 22, 2016 at 10:48 am March 22, 2016 at 10:48 am Comments 3 Share 1 Tweet Share Reddit Email It seemed inconceivable to them that a steel casing 8 inches in diameter could stop a machine weighing 7,000 tons, measuring 58 feet in diameter and pushing with 31 million pounds of thrust. Written by Amanda Foley on 03/04/2013 in News. On Friday morning, December 6, the machine had to stop multiple times to cool down. It was the world's biggest tunneling machine when it first chewed into the loose dirt and gravel on Seattle's waterfront in 2013. That meant the machine wasn’t scraping or cutting even though Bertha was operating at its maximum thrust of 100,000 kilonewtons. It’s unclear how many times this process was repeated before they gave up. The Japanese from Hitachi were honorable, always helpful. “Bertha, the largest TBM ever built, ‘raising the bar,’” wrote Juan Louis Magro, a construction manager for Seattle Tunnel Partners (STP), the joint venture of Spain-based Dragados and California-based Tutor Perini contracted to build the Alaskan Way Viaduct replacement tunnel. By December 2013, Bertha had left those issues behind it. All rights reserved. In every tunnel dig, the workers said, the first 600 feet or so they were adapting to their new TBM, learning how to operate it and making adjustments. “Isn’t that power or what?” Magro wrote, punctuating his email with a smiley-face. After finishing about 10% of the job, it broke down. Welcome to Primitive Monkey! Ad Choices, After 4 Years, Seattle's Giant Tunneling Machine Finally Breaks Through.

The WIRED conversation illuminates how technology is changing every aspect of our lives—from culture to business, science to design. (Dismemberment beats being buried alive: After a 200-ton tunneling machine finished its work under New York City, workers abandoned it instead of hauling it back up. Towards the end of WWI the Germans used a gun with a range of over 70 miles to shell Paris. Sometime the following morning, on Wednesday, December 4, the operators began seeing 3- to 4-foot pieces of pipe and a bunch of smaller pieces showing up on the video feed of the conveyor belt. (STP also sued Hitachi in the hope of covering cost overruns in the event the insurers wouldn’t pay the claims.). The American mechanic told Jim that even the Spanish mechanic was furious about what his bosses were doing. Hitachi argued that the problems were caused by a combination of things, a kind of perfect storm that included Bertha’s running into the steel well casing as well as operating errors by STP. The SR 99 tunneling machine, nicknamed Bertha, has completed her work. Big Bertha is the name of a type of super-heavy howitzer made by the famous armaments manufacturer Krupp in Germany on the eve of World War I. “When you hit something hard, usually there is a spike in the readings,” says Paul. They’ll decide if parts can be salvaged for use on other projects, or if they should be recycled. Investigation later revealed that its seals and bearings had been damaged from overheating. I’ve worked with Germans and French. Of course they say it has absolutely nothing to do with the digging of the tunnel. The workers had read ”Spin Zone,” which Seattle Business magazine published in October. Bertha has made it to the finish line. For that story, we spoke with executives and workers at Hitachi Zosen in Seattle and Japan to provide a perspective that challenged the prevailing view that Hitachi had somehow failed by building, in the words of Washington Governor Jay Inslee, a “Datsun” when something far more powerful and reliable was required.

WDOT apparently fears that a successful claim by STP against its insurers would strengthen STP’s position in a second case to be argued in Thurston County, likely sometime next year, which will determine who should cover additional costs of a half-billion dollars related in large part to Bertha’s breakdown and resulting delays. In a calmer spring—when facts weren't so slippery, social media so noxious, the country so ready to combust—what happened in Forks, Washington, on June 3 might have been a perfect plot for a farce. Maybe the cutters were damaged,” says Jim. This story follows our feature story, "Spin Zone," which appeared in the October 2017 issue of Seattle Business magazine. He figures that was from going through landfill, which “hadn’t been touched since 1887” and had trapped all manner of gases. "Big Bertha" is the name of a marine arachnid-type Hyperspecies Abnormal. “Normal operating procedure would be to stop and check things out to see what was going on,” says Jim. On the shift that began at 7 p.m. on Tuesday, December 3, Bertha was moving at a fast clip. The breakthroughs and innovations that we uncover lead to new ways of thinking, new connections, and new industries. A Spanish operator was running the machine. Video Ep: 395 - Dr. Alan Hocknell Takes Your Questions on the New Big Bertha B21 Family . STP designers had specified that Bertha be built using a “ribbon screw” precisely because the massive screw’s hollow interior allowed it to pull rocks as much as 3 feet in diameter up onto the conveyor belt. The two workers who read the story, however, offered additional details that confirm and clarify many of the issues addressed, issues that will be at the center of the two upcoming court cases. It was very responsive.” The second worker — we’ll call him Paul — also had operated Bertha and agreed. Name. One operator was at the main controls, a second operated devices that sprayed grout to fill open space above the curved, interlocking concrete segments that Bertha placed in a ring to extend the tunnel six feet at a time. Tunnel boring began on July 30, 2013, with the machine originally scheduled to complete the tunnel in December 2015. Bertha's journey has been a slow one, even when compared to other boring projects. The Spanish operator then proceeded to push the machine’s thrust to 325,000 kilonewtons, three times the maximum thrust Bertha was designed to handle. And on Tuesday, it finally gnawed through the concrete wall of a newly constructed, 90 feet deep, ‘disassembly pit’. 1Story updated at 3.15p EST 04/07/17 with details on the damage and repair. Eventually he’d like to see a network of tunnels up to 30 layers deep under cities, with traffic whizzing in three dimensions, instead of just two on the surface. Ah, Bertha.
