The American Institute of Architects has released an Excel-based tool that generates a report on predicted energy use and project modeling. The tool, called the 2030 Commitment Annual Progress Reporting Tool, is part of the group's push to get its members to design carbon-neutral buildings and practice architecture in a more sustainable way. Although the tool was designed for architecture firms only, it is being tweaked for use by structural engineers. AIA released the tool at its 2010 convention in Miami. To date 105 architects have signed on to the AIA's voluntary 2030 commitment program, said Kelly Pickard, AIA's project
A 98-year-old, accident-prone southeast Texas bridge is being upgraded following a long and bumpy bidding process. The U.S. Coast Guard declared the rolling-lift single-leaf bascule causeway bridge connecting Galveston Island with Texas a navigational hazard in 2001. Old bascule bridge was subjected to repeated barge collisions. The 108-ft-wide bridge often is struck by barges, costing more than $2 million in repairs each year, says Raymond Butler, Gulf Coast Intracoastal Canal Association�s former executive director. A new structure�designed by Galveston County with Mechanicsburg, Pa.-based Modjeski and Masters�triples the clearance width. Bids came in higher than expected in October, resulting in value-engineering
The U.S. Dept. of Transportation has pledged to work with an influential industry group to encourage more girls and young women to embark on transportation careers. DOT Secretary Ray LaHood last month signed a memorandum of cooperation (MOC) with the Women’s Transportation Seminar International last month in Washington D.C., noting the need in particular for environmental engineers is expected to rise by 30% over the next decade.

Members met with the U.S. DOT in April. “Lightbulbs
A massive effort to revamp the American air-traffic-control system from land-based to satellite-based equipment, dubbed NextGen, could result in greater flight efficiency and fuel cost savings at all major hubs by 2014, says Randolph Babbitt, Federal Aviation Administration chief. He also stressed the need for the next generation of land-side and air-side infrastructure. div id="articleExtrasA" div id="articleExtrasB" div id="articleExtras" Babbitt urged members of the American Association of Airport Executives last month in Dallas to work toward implementing multimodalism. “We have to advance our infrastructure to NextGen standards,” he said. “It’s the only way to keep pace with the rest of
The Washington State Dept. of Transportation is creating a list of best construction practices for floating bridges, based on results of tests conducted on a pontoon built at one-sixth the typical size. The best practices will be used by the design-build team that won the contract to build new pontoons for the state Route 520 Evergreen Point Floating Bridge. At 2,285 meters, SR 520�s bridge is the longest of its kind in the world.

Last month, more than 1,100 lb of strategically placed explosives brought down the 24,000-ton, 455-ft-tall cooling tower at the U.S. Dept. of Energy’s Savannah River site in Aiken, S.C., the second largest such structure to be imploded, says the firm. “The implosion surpassed everyone’s expectations,” says Doug Loizeaux, vice president of Controlled Demolition Inc. (CDI), Phoenix, Md. The firm was the explosives preparation and performance subcontractor to American Demolition and Nuclear Decommissioning, Grand Island, N.Y., which received the approximately $4-million contract to implode the former nuclear-site cooling tower and remove debris. The latter task will be handled by LVI Services
In an otherwise troubled time for new coal-fired projects, the Mississippi Public Service Commission has approved Gulfport, Miss.-based Mississippi Power�s plans to build a new 582-MW integrated gasification/combined-cycle plant in Kemper County�but with a $2.88-billion cost cap. Photo: Southern Cos. Regulators set a $2.88-billion construction cap�after an initial $2.4-billion limit�on Mississippi Power�s planned 582-MW plant. The utility owner had asked for $3.2 billion. Mississippi Power plans to complete the Kemper project as soon as 2014, said utility spokeswoman Cindy Duvall. The prime construction contractor will be selected soon, with project construction to be managed by Southern Co. Engineering and Construction
As contractors mobilized to berm Louisiana’s shoreline to protect its wetlands from oil gushing out of a ruptured well in the Gulf of Mexico, the nation focused on the plan’s chances for success, the disaster’s economic and environmental consequences, and the future of the region’s offshore oil industry. A computer modeling study released on June 3 suggests the oil from the spill in the Gulf of Mexico may extend up the Atlantic coast and into open ocean as early as this summer. Crews mobilize heavy equipment to build oil-blocking berms on Dauphin Island, Ala. var so = new FlashObject("http://natalie.feedroom.com/construction/natoneclip/Player.swf","Player", "300",
The Washington Monument in Baltimore has been closed to the public in light of a recent engineering study that found its parapet to be unsafe. CVM Engineering of Philadelphia studied the 178-ft-tall marble monument, which predates the Washington Monument in Washington, D.C., as part of a $200,000 master plan to restore the monument and its surrounding squares. CVM reported that, on the parapet, mortar between slabs was missing and metal support brackets were rust- ed and should be replaced. Engineers recommended $1 million in total repairs, including $300,000 for work on the parapet. The monument, which was completed in 1829,
The U.S. Green Building Council is defending its decision to uphold the highest certification to be granted a public high school under its green-building rating system, called Leadership in Energy and Environmental Design. The engineers who filed the challenge to the LEED-New Construction Gold certification on behalf of a group of taxpayers in Eagle River, Wis., say the decision to uphold the certification damages the credibility of USGBC. The consulting engineers were pro bono technical experts for the five people who filed the 125-page appeal on Dec. 23, 2008, when Northland Pines High School was two years old. Consulting engineers
