The Vancouver International Airport is planning $1.8 billion in capital projects over the next 10 years, with a heavily front-loaded first four years that already has out requests for proposals for the initial package of work.
As detailed engineering progresses, Canada's Imperial Oil is evaluating plant contractor bids following its decision to rekindle plans to construct a $2-billion expansion to its Cold Lake facility operation in northeastern Alberta's oil-sands region. The revised plan includes a 170-MW cogeneration facility and a bitumen-processing plant to go on line by the end of 2014.
In-water work restrictions are so tight in the salmon-filled rivers of western Oregon that the Oregon Dept. of Transportation decided to employ a top-down bridge construction method to replace a section of Interstate 84 east of Portland. If all goes well, say ODOT officials, the method may be adopted on a more frequent basis.
D. Kent Smith is well aware there are no shortcuts when it comes to cleaning up 60 years of radioactive and other wastes at the U.S. Energy Dept.'s Hanford former nuclear-weapons site in Washington state.
After a bump, the demolition of Seattle's Husky Stadium is moving ahead.Despite stressing a crane to the point of damage when dismantling the overhanging roof on the south side of Seattle’s Husky Stadium, Turner Construction Co., the project's general contractor, was able to continue roof demolition from the grandstand seating area, says Richard Teddy, Turner’s senior project manager.Demolition crews utilized cables and a cutting shear on a high-reach extendable track-hoe to remove the roof and upper seating areas, which are being demolished and hauled out for recycling. No additional crane was needed. Demolition crews will now work into February removing
YouTube Video shows crane near miss at Husky Stadium at the University of Washington in Seattle. Related Links: Watch the Video A video of Seattle's Husky Stadium roof demolition went viral on the web as fans clamored to get a look at the start of major renovations at the famed 90-year-old structure. But a near miss captured in that same video also got the attention of the Washington State Dept. of Labor and Industries, launching an investigation into the operation of a crane there.The video clearly shows a massive jarring, or shock-loading, to a crane while the east portion of
CH2M Hill Plateau Remediation Co. Workers remove the east end of a highly contaminated tank in the 209-E Critical Mass Laboratory to provide access to two storage tanks as part of the facility's demolition. CH2M Hill Plateau Remediation Co. Crews spent two months developing mockups, even fabricating non-contaminated replica tanks, to insure safe demolition of 11 large tanks formerly used in weapons production experiments. With radioactive contamination saturating the 209-East Critical Mass Laboratory at the U.S. Dept. of Energy’s Hanford Nuclear Waste Site in southeast Washington, contractor CH2M Hill Plateau Remediation Co. needed new techniques to demolish the nearly 9,000-sq-ft
Photo: ODOT Unstable earth and lateral loads have stymied completion of a U.S. 20 project. After millions of dollars in costs and years of delays, the Oregon Dept. of Transportation has labeled as a failure the landslide mitigation on an unfinished four-mile stretch of U.S. 20 between Pioneer Mountain and Eddyville.In an attempt to bypass a windy 10-mile roadway prone to landslide damage, Yaquina River Constructors—whose parent company is Watsonville, Calif.-based Granite Construction Co.—planned to build a total of 11 bridges for its design-build contract. Seven are now complete. The remaining four bridges were to range from 600 ft to
A decade after work began on the $12.2-billion waste treatment plant at the U.S. Dept. of Energy's Hanford site in southeastern Washington—set to be the world's largest to treat "mixed" nuclear and chemical wastes—the 65-acre "vit plant" complex still faces uncertainty in cost and design, despite completion of 85% of its engineering and more than 60% of its construction.The difficulty of designing the facilities needed to turn Hanford's 56 million gallons of liquid radioactive and chemical wastes into vitrified glass has DOE and its main contractor, Frederick, Md.-based Bechtel National, cautious as they stare down a 2013 design completion deadline
