Economist expects continued construction slowdown

In a state-by-state forecast, Portland Cement Association (PCA) Chief Economist Ed Sullivan predicts that the emerging weakness in residential construction will dissipate the strong growth recorded earlier in the year in many regional markets. &quotIn July, 24 states showed significant declines in housing permit activity, including traditionally strong markets such as Nevada, Florida, and Arizona,&quot Sullivan says. &quotI do not believe these declines will be temporary.&quot

Applied engineering

According to USA Today, Pittsburgh Steeler Offensive Coordinator Ken Whisenhunt credits his degree in civil engineering from Georgia Tech with helping him call plays. "There are a lot of people who are glad I didn’t put my degree into practice on all those bridges and roads out there," Whisenhunt said. "But the school was difficult, and you have to be creative in how you solve problems in civil engineering. So that’s where my degree has translated well for me in play calling."

A recent National Science Foundation (NSF) survey found that people who earned a bachelor’s degree in science or engineering (S&E) generally report that their science and engineering knowledge is important to their job, even if it’s non-technical work.

According to the survey, among those workers whose only degree was an S&E bachelor’s degree, 27 percent had S&E occupations. Sixty-three percent working in non-technical fields still said their jobs were related to their S&E degree.

Of those who went on to receive advanced degrees, the largest proportion, almost 29 percent, took those degrees in non-S&E fields, namely business, law, or medicine. "S&E knowledge remained important to the jobs of most S&E bachelor’s holders with advanced degrees, being reported as necessary by a majority of both those with master’s degrees in business and those with other non-S&E advanced degrees," the NSF report said.

President nominates Mary Peters as Transportation Secretary

President Bush nominated Mary Peters, former head of the Federal Highway Administration (FHWA), to be the next Secretary of Transportation. If confirmed by the Senate, Peters will succeed Norm Mineta, who served as Transportation Secretary for six years, a record term for the position. "Mary Peters is the right person for this job," said Bush. "She brings a lifetime of experience on transportation issues, from both the private and public sectors."

Peters joined the Arizona Department of Transportation (ADOT) in 1985 and was appointed ADOT director in 1998. She served as head of FHWA from 2001 to 2005 and, most recently, as senior vice president for consulting firm HDR, Inc. Peters led FHWA’s efforts to complete a multi-year authorization of surface transportation programs. According to the Washington Post, she is an advocate of user fees (tolls) to fund construction of new highways.

Seismic dampers installed in a residential structure

Just weeks after the University at Buffalo (UB) and Rensselaer Polytechnic Institute (RPI) successfully conducted the first tests of seismic dampers for residential applications, the firm that manufactures the dampers, Taylor Devices, made its first sale of the protective devices for a residence in California.

Commuter payback

At 12:33 a.m. on Aug. 29, Dan Ruefly of Accokeek, Md., achieved ultimate payback for the frustration and pain he has faced for 28 years from traffic jams caused, in part, by the old, narrow Woodrow Wilson Bridge spanning the Potomac River between Maryland and Virginia on the south side of Washington, D.C. As winner of the Woodrow Wilson Bridge Project’s Toughest Bridge Commute contest, Ruefly got to trigger detonation charges that cut and brought down about a half-mile stretch of elevated steel girders that supported the old bridge. (Watch a video of the blast at www.wilsonbridge.com/bridgeDemolition.htm.) Ruefly endures a daily, 120-minute commute to work and a 90-minute commute home. Additionally, in 1999 he was involved in a serious accident on the old bridge. Ironically, Ruefly attended the dedication ceremony for the old bridge in 1961 when he was eight years old.

A new Woodrow Wilson bridge opened in June, which currently is carrying both northbound and southbound traffic on I-95. Following demolition of the old bridge, a second new span will be built in its place to carry southbound traffic. The project remains on schedule to open the second new bridge in mid-2008.
