Crux Subsurface is a unique drilling company, getting their start with limited and difficult access geotechnical drilling, but in recent years, they have branched out into micropile foundation design and construction. They frequently work for […]
Hersheypark is a famous amusement park in Hershey, Pennsylvania. The park looked to GeoPrac sponsor Nicholson Construction for micropile foundations for their new $12.5M Storm Runner roller coaster. The ground conditions consisted of highly variable […]
Specialty geotechnical drilling contractor, Crux Subsurface, Inc. of Spokane, Washington was acquired Quanta Services (NYSE: PWR), an S&P 500 company and a leader in infrastructure services for the electric power, pipeline and telecommunications industries according […]
Crux Subsurface, Inc. of Spokane, WA was recently awarded a contract by San Diego Gas and Electric to provide design and installation of micropile foundations at 16 tower locations along a 7 mile stretch of […]
An arena being built for the Philadelphia Flyers’ minor league affiliate hockey team will be founded on micropiles to mitigate possible sinkhole problems in the limestone bedrock. The arena in located at the site of […]
The tunnel replacing the Alaskan Way Viaduct (SR-99) will pass beneath 158 existing structures requiring an extensive program of vibration and settlement monitoring as well as some remediation. Of the 158 buildings, WSDOT identified 20 […]
In an August 2010 article in ADSC’s Foundation Drilling Magazine, Eric Loehr and Dan Brown of Dan Brown and Associates summarized the key findings from a report they authored on the use of micropiles in […]
This has to be one of the most complex geotechnical engineering problems I’ve heard of for a building, if not for any kind of project. For starters, beneath the proposed 10-story office building referred to as Cannon Place lies the Cannon Street Train Station built in 1868. Also beneath the site are walls and foundations of a Roman Governor’s palace. In order to accommodate these features, the building has 21-m cantilevers at each end, with the load bearing happening over two groupings of columns at the 1/3 points. In section it looks quite like a 3-span bridge…without the abutments and stacked 10-stories tall! More after the break. (Images by New Civil Engineer) […]

[Updated Thursday May 29, 2009 – 1:00 PM PDT] Added a photo of the AIS Kaiser S2 excavator (spider excavator), and added photos of the Devil’s Slide debris dump where they have put the landslide material removed and the material from the tunnel excavation. [/Update]
Grant Wilcox, Geology Branch Chief with CALTRANS Office of Geotechnical Design West gave a presentation on the Devil’s Slide repair along PCH Highway 1 at the Southwest Geotechnical Engineer’s Conference on May 12 in Phoenix. I’ve posted about the project here before. When I saw Mr. Wilcox, I knew he looked familiar but I couldn’t figure out why. At the beginning of his presentation he made light of his being on You-Tube…then it clicked! He gave a nice overview of the history of the failures, the geology, and the tunnel project. What follows are a few quick tidbits from his talk based on my notes. (Photo via Caltrans site).
