NationalDriller.com’s Foundation Report eNewsletter had an article about the foundations for Donald Trump’s latest hi-rise project in Las Vegas, Trump International Hotel & Tower Las Vegas. Anderson Drilling was the foundation contractor for the 294 drilled shaft foundations to support the 64-story building.
According to ENR, the U.K. government has approved the 7-year, $32-billion London Crossrail Project which will reportedly be Europe’s biggest civil engineering project. It will include 41.5-km of tunnels 6-m in diameter laid out in pairs. The tunnels will pass underneath London and connect surface networks on either side of the city. Link after the break.

Indonesia is planning to build what will be the World’s longest suspension bridge to link up its two main islands of Java and Sumatra. The total length will over 30-km with a (max?) height of 70-m so ships can pass underneath. The catch is that the bridge will be located on the Pacific Ring of Fire, the boundary between the Asian and Australian tectonic plates and one of the most seismically and volcanically active areas in the world. There have been several recent earthquakes greater than magnitude 7, not to mention the earthquake that caused the 2004 tsunami. The bridge will be built to withstand a magnitude 9 earthquake. Oh, and in case the seismic concerns weren’t great enough, the bridge will pass within 50-km of the volcano Krakatoa. The estimated cost of the bridge is $12 billion ($AU?).

A stretch of tunnel on Eastbound I-70 in scenic Glenwood Canyon Colorado was closed last March because of a 70-foot long crack in the ceiling. Since then the two-lane westbound bore has been handling both eastbound and westbound traffic while repairs to the damaged segment were undertaken. This project has a little of everything: heavy excavation, rockfall, slab reinforcing, geofoam, and even geogrid! Read on for more details, a map and photos. (Photo by Concrete Works Of Colorado)
According to the UK’s TimesOnline, a report issued by the Xinhua news agency, mouthpiece for the Government, said: â€œThere exist many ecological and environmental problems concerning the Three Gorges Dam. If no preventive measures are taken, the project could lead to catastrophe.â€ More after the break. (Photo by enkai)
When you hear about the Tacoma Narrows Bridge, most people may think of the old Galloping Gertie footage (just for fun, I’ll add some video after the break). Of course the original bridge collapsed in 1940 shortly after opening. A new bridge was completed in 1950, and a second bridge was just opened to traffic on July 15, 2007. Gerard Buechel, the president of Shannon Wilson, examines the geotechnical challenges of constructing this massive bridge in an article post on DJC.com. Imagine constructing a 20-story reinforced concrete building, now imagine constructing it entirely under water! Read on for the link to the article and Galloping Gertie video. (Photo by frarytd)
