As accelerated bridge construction (ABC) catches on quickly in the United States—particularly in Utah—a former Federal Highway Administration engineer now at the Oregon Dept. of Transportation wants to create national standards for the practice. Rapid bridge replacement method may get standards. Benjamin Tang, ODOT’s bridge preservation managing engineer, says readily available criteria adaptable nationwide can help bridge owners establish when ABC construction makes sense. “We are trying to create something that addresses some of the criteria used by the owners to make choices that will result in the best selection,” he says. “Putting quantifiable data, when available, into the model

Construction of a 700-ft-long footbridge�cantilevered out on 20 steel beams and clinging to the side of a canyon in North Vancouver, British Columbia�has been an adrenaline-pumping building project that, when finished, will leave tourists breathless.

Large dam upgrades in North America are squeezing every megawatt out of the grid as efficiently as possible by converting century-old powerhouses and replacing decades-old turbines. Construction is under way at several sites, from Pennsylvania to British Columbia. Earlier this month, PPL Montana began upgrading its Rainbow Dam, a 36-megawatt dam on the Missouri River, six miles northeast of Great Falls, Mont., where 200 workers are under the direction of Chicago’s Walsh Construction.

Three of Portland’s four most noticeable construction projects include some type of housing—either affordable, homeless or retirement—while the fourth project creates an intimate home for the Portland Timbers of Major League Soccer, the city’s newest big-league sports franchise. Lew Bowers, central city division manager for the Portland Development Council, says that in the short term, his agency wants to see smaller, sustainable rehabilitation projects. “Long term, we don’t see a return to large, single-developer projects,” Bowers says. “Instead, we’re focusing on master planning with opportunities for a variety of developers to participate on specific parcels so projects are ready as

Work is under way on a $571-million upgrade to a mountainous, five-mile stretch of Interstate 90 - Washington’s busiest east-west connector. Located miles from Seattle, the scenic highway, which is part of Snoqualmie Pass, weaves through the Cascade Range. The Washington State Dept. of Transportation’s comprehensive plan calls for widening the road from four lanes to six, repaving it with freeze- and thaw-resistant concrete, straightening curves, stabilizing rock slopes, and adding a chain-up area and 1,200-ft.-long snowshed. Moreover, WSDOT will add or replace four bridges and build four new ones bridges and culverts in an effort to improve fish and

Tight working footprints and even cozier timelines highlight the ongoing reconstruction of Issaquah High School in Washington as Bothell-based Cornerstone General Contractors pushes through its summer rush, striving to complete the school’s classroom and core areas in time for the return of students this fall. The $84-million transformation of the high school is the flagship project of a $241-million 2006 bond that includes work on more than a dozen Issaquah School District projects. It changes the high school from one built in the mold of 1960s open-circulation designs into a larger, low-impact, modern campus. The 285,000-sq-ft school is being built
