Mark Loizeaux, president, says internal cameras confirmed that the process worked as planned. CDI used the tension of tendons in the structure to tilt the tower to compensate for the list, then undermined it to create an eccentric load, rotated it slightlyand dropped it into a pile
A new pilot program launched by the American Society of Heating, Refrigerating and Air Conditioning Engineers (ASHRAE) will provide both design and operational ratings for all building types, except residential buildings; the ratings will be posted on the buildings themselves. The “Building EQ” program is designed to give building owners, designers and potential buyers a more realistic sense of how buildings are actually performing in terms of energy use, ASHRAE officials said at the launch of the program in Washington, D.C., at the Dec. 7-11 Ecobuild conference, sponsored by the National Institute of Building Sciences. Initially, volunteer ASHRAE members will
Congress has approved the latest in a series of extensions to allow Federal Aviation Administration programs, including its Airport Improvement Program (AIP) construction grants, to continue operating. The new stopgap runs through March 31. Final congressional action came on Dec. 10, with passage by the Senate. The House had approved the measure two days earlier. The bill next goes to the White House, for President Obama's expected signature. The measure would succeed the current stopgap, which expires Dec. 31. House Transportation and Infrastructure Committee Chairman James Oberstar (D-Minn.) notes that the extension includes $2 billion in contract authority for AIP,
A joint venture of Barnard Construction Co. Inc., Bozeman, Mont., and Judlau Contracting Inc., College Point, N.Y., edged out two other prequalified teams to win a $583-million contract to bore a pair of 16,500-ft-long, 27-ft-dia., tunnels averaging 120-ft deep for the Manhattan portion of an $8.7-billion second mass-transit tunnel linking New York's Pennsylvania Station to New Jersey. Directors of project owner, New Jersey Transit, unanimously approved the contract on Dec. 9. Proposals for a related tunnel contract under New Jersey's Palisades rock formation, estimated at $250 million, will be due Dec. 15, says a New Jersey Transit spokesman They are
Facing unpredictably tough ground conditions, tunneling crews have worked all out this year to get Belfast’s $195-million, 9.4-kilometer-long stormwater storage tunnel system operational before Christmas. With work largely done, Northern Ireland Water (NIW) aims to recruit soon a design firm to handle its second deep-tunnel sewer project, likely to be just as tough to implement. Slide Show Photo: Northern Ireland Water Belfast CSO system has 19 shafts up to 10 m in diameter. The shafts and tunnels will be able to hold 85,000 cu m of wastewater.

A Pacific Northwest dam removal project, said by its owner, the National Park Service, to be the largest of its type in the U.S., is one step closer to beginning after the recent completion of a new water treatment plant in Port Angeles, Wash. NPS officials expect contractors to proceed with dismantling Elwha and Glines Canyon dams on the Olympic Peninsula in 2012. Photo: National Park Service. Demolition and removal is to start in 2012. Congress approved removal of both Elwha River impoundments in 1993. Demolition was scheduled for 2009, until rising costs for the $308-million project delayed the start
The anticipated costs to contractors to comply with the U.S. Environmental Protection Agency’s final rule addressing stormwater runoff on construction sites outweigh any benefits to water quality, say industry representatives. Critics charge the new rule, published in the Dec. 1 issue of the Federal Register and which will go into effect on Feb. 1, 2010, imposes new costs and burdens on builders while doing little to address water quality. EPA and environmental advocates say the new rule, required under a 2006 court order, will help reduce pollution from construction sites into the nation’s rivers and streams. The final rule requires

The government of Brazil has announced it is seeking bid proposals for a 317-mile high-speed rail line linking São Paulo and Rio de Janeiro. The project would be the first of its kind in South America, which currently has no high-speed rail lines. The project currently has an estimated budget of $19.44 billion and would serve a corridor that is home to 40 million people—20% of Brazil’s population. Under the current plan, 60% of the cost would be funded by Brazil’s development bank, and the remaining 40% would be provided by the winning bidder, which also would receive a concession
An unusual wave-power system that pumps high-pressure water to an onshore hydroelectric plant recently began feeding electricity into the U.K.’s national transmission system. The 315 kW “Oyster device” is the world’s only functioning hydroelectric wave-powered plant, claims its Edinburgh-based developer, Aquamarine Power Ltd. Slide Show Photo: Aquamarine Power Ltd. The 200-tonne 315-kW wave-power device was installed in Scotland for six months of full-scale demonstration trials.
