Kansas City, Mo. (Aug. 5, 2009) – The U.S. Army Corps of Engineers (USACE) has selected Black & Veatch as the design engineer for the McCook Reservoir Main Tunnel. The new tunnel will connect the future McCook Reservoir to Chicago’s Deep Tunnel system, which is aimed at improving water quality in area rivers and Lake Michigan and reducing flood risk for the city of Chicago and suburban communities.

Innovative Foundation System for London Office Building

Cannon Place office building in London 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) […]

Video: Sand Filled Geotextile Tubes To Protect Grand Isle Louisiana

Geotubes to protect Grand Isle Louisiana In this ENR.com video, a US Army Corps of Engineers (USACE) project to protect Grand Isle Louisiana from the erosional effects of a large storm surge is described. 5.7 miles of sand filled geotextile tubes or geotubes 30-ft in diameter are used to form the core of a dune along with a geotextile erosion apron held in place by anchor tubes. The design is aimed to prevent devastating erosion in the event that a large storm surge overtops the protective dunes. The sand is screened on site and mixed with water to form a slurry that is pumped into the tube. Once the tubes are in place, additional sand will be placed over the top and the dune revegetated. If the topping sand is eroded away, the Corps hopes the fix will be easier to perform with the tubes. Click through for the video.

Landslides in China – Sichuan and Guangxi

In Sichuan Province, China, they were still in the recovery process from the devastating 2008 earthquake when a series of landslides, rockfall, mudslides and flooding has hit the region. Dave’s Landslide Blog has excellent coverage as usual on the slide pictured here, which blocked a major road, hindering rescue efforts. (Photo Xinhua/Jiang Hongjing)

A remarkable video of the aftermath of a bridge destroyed by one of these rockfall / landslide events is shown below. The destruction is pretty profound. (Via Geology.com)

Also on Dave’s blog, a landslide in Guangxi caused a train to derail, killing 4 people and injuring 50. My heart truly goes out to the people of those portions of China, particularly in Sichuan as they have been through so much.

Indefinite “Temporary” Nuclear Waste Storage and the Need for Nuclear Power

image Since the Yucca Mountain nuclear waste repository has gotten the axe from President Obama, nuclear power plants around the country are faced with the prospect of virtually indefinite "temporary" storage of their nuclear waste in the form of spent fuel rods. The US Department of Energy has a legal obligation to find a permanent disposal facility for the spent fuel, and the agreements currently in place presumed that Yucca Mountain would be accepting nuclear waste by 2025 which clearly won’t happen. (Photo of dry cask temporary storage method for spent nuclear fuel from Connecticut Yankee). More after the break. […]
