Smarting from a second emergency closure of the Oakland-San Francisco Bay Bridge in two months, the California Dept. of Transportation is exploring long-term repairs for a cracked eyebeam until the crossing’s $6.3-billion modernization is completed in 2013. Caltrans engineers are considering replacing part or all of the truss system that has a cracked eyebeam, discovered by inspectors on the 73-year-old cantilevered eastern span during a Labor Day closure. Rancho Cordova, Calif.-based C.C. Myers Inc. was installing a 288-ft detour ramp as part of the reconstruction when inspectors found the 1½ in. crack in a 2-in.-thick, chain-like steel beam. The cracked
Emergency teams worked to retrieve the bodies of four of five workers who died after falling 15 meters in a bridge falsework collapse on Nov. 7 in the tiny Pyrenees principality of Andorra. Six more were injured. The accident occurred at the western portal of the recently completed Dos Valires tunnel. The men were working on falsework for a twin-deck, partially cable-stayed bridge being built as an access to the 2.9-kilometer-long tunnel from an existing highway. Workers reportedly had been pouring concrete for several hours when the falsework collapsed. No official cause has been given as investigations continue. The bridge’s
A joint venture to develop up to 100,000 MW of solar power in Middle Eastern and North African deserts by 2050 was formed on Oct. 30 in Munich. The group DII GmbH is owned by 12 major firms, most of them based in Germany, including Siemens A.G., Deutsche Bank A.G. and the DESERTEC Foundation. DII ultimately aims to supply as much as 15% of Europe’s electricity demand and a substantial part of local needs.
NRG Energy Inc., Princeton, N.J., has purchased Bluewater Wind, Newark, Del., the first U.S. developer with a purchase agreement for the sale of power generated from an offshore wind farm. The deal brings the financial strength of NRG, which had $6.8 billion in sales last year, to Bluewater, helping the startup firm realize its dream to develop a $1-billion, 79-turbine commercial wind farm off the Delaware coast.
Development of two new nuclear units in Texas could be delayed or put further at risk after estimates for the reactors rose 30% last month to $17 billion. The price escalation shocked San Antonio, Texas, municipal utility CPS Energy, which has a 40% stake in the South Texas Project in Matagorda County. The company’s board of trustees ordered an investigation into whether information about the price escalation for the 1,358- MW advanced boiling water reactor units was kept hidden. “A cost estimate that exceeds our preliminary total project cost of $13 billion is not acceptable and will result in CPS
The $2-million Sustainable Sites Initiative, having included its four-star rating system within its guidelines for developing and maintaining healthy landscapes, is seeking applications for 75 to 150 pilot projects to test the credit-based program. Applications to SSI, which is taking the first comprehensive look at sustainable landscape design, construction and maintenance, are due by Feb. 15.

On Nov. 5, SSI released the 233-page “SSI: Guidelines and Performance Benchmarks 2009” and “The Case for Sustainable Landscapes,” a set of economic, environmental and social
The scheduled December groundbreaking of the first phase of the $5.5 billion Honolulu Rail Transit Project has been delayed by at least a month, says project spokesman Scott Ishikawa. “Based on the time needed to get participating agencies to review the draft environmental impact statement and the time needed for the federal and state level to approve the final EIS, we decided to push back construction until the end of January,” he says. In late October, the city awarded the $482.9-million first-phase contract to Omaha-based Kiewit Pacific Co. The 6.5-mile design-build project is expected to take three years to complete.
Expert crews are rappelling down a steep wall of jagged, unstable rocks above Interstate 40 in western North Carolina, beginning the cleanup and repair process of an Oct. 25 rockslide that shut the highway down. The repair could take four months and cost $10 million. The 500,000-ton rockslide on U.S. Forest Service land caused the North Carolina Dept. of Transportation to declare an emergency and Gov. Beverly Perdue (D) has asked the U.S. Dept. of Transportation to declare the rockslide a federal disaster area. Crews with contractor Phillips & Jordan Inc., Knoxville, Tenn., are working with rock stabilization specialists from
Another behemoth civil works project is taking shape in New Orleans as construction of the $1 billion Gulf Intracoastal Waterway (GIWW) West Closure Complex project rapidly advances. Since receiving the notice to proceed August 4, Gulf Intracoastal Constructors, a joint venture of Omaha-based Kiewit Corp. and Traylor Bros. Inc. of Evansville, Ind., has been working round-the-clock. GIC has already cleared and grubbed most of the 200-acre site, built 4,000 ft of roadway, and excavated 150,000 cu yd of dirt.

While the overall economy shows signs of slowly coming back to life, the airline industry continues to struggle. Over the past year, the combination of substantially lower passenger traffic, still-wobbly financial markets and nervous carriers has curtailed the revenue streams airports typically count on for major capital projects.
