Seattle Tunnel Partners released a new schedule this week for the repair of the damaged seals on the Bertha Tunnel Boring Machine. This revised schedule shows that the TBM won't be digging again until March of 2015. The excavation of the pit to access the TBM will begin at the end of May, a delay caused by additional archaeological work. By October they hope to have the cutterhead removed to conduct the repairs, and the machine will undergo testing in February of 2015 with tunneling resuming in [...]

Seattle Tunnel Partners has released a conceptual plan showing what the excavation of the pit will look like to repair the damaged Bertha Tunnel Boring Machine. See below. A pit 120 feet deep and 83 feet in diameter will be excavated so that the TBM can be driven into the pit and the cutterhead removed. Crews will then repair the seal system around the main bearing.

A developer will pay $3.2 million in damages plus $3.9 million in legal fees and expenses to the owner of a property that sustained structural damage related to the shoring of the developer's adjacent 17 story apartment building in Bethesda, Maryland. Apparently the developer settled with the owner regarding the damages 4 days before trial in December of 2013. The details of the settlement were released in a court order last week that was associated with a hard-fought battle over the legal [...]

I love how the Atlantic Cities article starts, they use the phrase "only in New York", which is very appropriate in this case! Foundation drilling has commenced for a project that will create 26 acres of developable space by creating a deck over the top of a Long Island Rail Yard serving America's busiest train station, Penn Station. Over 300 drilled shafts extending 90 feet down to bedrock will be constructed to support a continuous concrete deck that will span over the entire rail [...]

The Oso Landslide death toll is now up to 29. This is one of the worst natural hazard disasters I can remember in recent times. First and foremost I think should be the memories of the victims. There are so many heart-wrenching stories of the people that lost their lives in this giant landslide. I think those stories underscore the importance of the jobs of geologists and engineers. We have a responsibility to protect life and property in the work that we do. I'm not saying this landslide or [...]

A magnitude 8.2 earthquake struck off the coast of Chile late Tuesday. The damage estimates will probably begin rolling in today, but early indications are that it could have been much worse. Some 5 people have been killed in the early figures. There have been reports of landslides and disruption of communication facilities. A tsunami warning was triggered, and there are warnings of high water levels and strong currents impacting Hawaii, but so far no reports of a major tsunami along the [...]

A massive mudslide occurred on Saturday in Snohomish County, about 30 miles north northeast of Seattle, east of Arlington in the town of Oso. It has killed 8 people and at least 12 are still missing. 30 homes were destroyed and a mile long stretch of HIghway 530 is buried under approximately 20 feet of mud and debris. Rescuers initially heard voices of survivors, but have not heard any voices since Saturday night. My heart goes out to the families of the victims. We will have more details as [...]

Hayward Baker working on sinkhole problem at Corvette Museum

I heard that Hayward Baker was working on the Corvette Museum sinkhole at GeoCongress, but I finally got official confirmation via this Civil Engineering Magazine article. It's a great article if you are interested in the engineering that's been going on since the sinkhole collapsed and swallowed 8 Corvettes. So far, Hayward Baker has installed 23 micropiles around the structure to depths of 75 to 220 feet depth according to the article. They are still trying to recover the remaining cars [...]

Plan for Bertha Repair Submitted, Archaeological Surveys Underway

Seattle Tunnel Partners and WSDOT are moving forward with the plans to excavate a 120 foot deep shaft to repair the Bertha Tunnel Boring Machine. Unfortunately, there are archaeological issues since the project team did not clear the area where the shaft will be excavated. A series of 4-inch boreholes 20 to 40 feet deep (I wonder what drilling method, sonic?) will be performed under the supervision of the archaeologists to look for culturally significant items. The top of Bertha sits [...]

A radar survey of Egypt's Valley of the Kings hopes to find some of the missing tombs of Egyptian Queens and Pharaohs that have so far eluded archaeologists. Distinguishing natural faults and other geologic features from potential tombs is one challenge. The article also describes how some other interesting discoveries have been made, including an ancient flood control system that prevented the tombs from being flooded, but rapidly fell into disrepair.
