Demolition began on June 1 at one of the largest-ever dam-removal projects in the U.S. Since 1921, the Savage Rapids Dam on the Rogue River near Grants Pass, Ore., has provided irrigation, but at a cost to the coho salmon that spawn in the river. A consent decree in 2000 capped a decade of legal fights and set the stage for the demolition. Photo: Slayden Construction Group Removal will open 500 miles of river for spawning. The 39-ft-high, 500-ft-long concrete-buttress dam was built in 1921 by the Grants Pass Irrigation District for irrigation only and provides no electricity or flood

As hurricane season dawnedon June 1, Shaw Environmental & Infrastructure Group, Baton Rouge, headed into production mode on construction of a $695-million, 2-mile-long, gated storm-surge barrier to help protect the southeast flank of New Orleans. By midsummer, more than 100 cranes and supply barges will be engaged. Under contract to the U.S. Army Corps of Engineers, Shaw is using a 500-ton crane to set and drive 66-inch-dia, 144-ft-long concrete spun-cast cylinder piles to form the vertical face of the surge-barrier wall. By June 4, a second crane of the same type is scheduled to join in. Shaw expects to drive

The one kind of surprise you might want if you were moving more than 500 ft of bridge section would be to have things slip and slide along even more smoothly than expected. That is what happened over Memorial Day weekend in Cleveland as crews moved the Innerbelt Bridge 4 in. to open up an expansion joint. Slide Show Photo: Ruhlin Co. Crews lifted the bolster, which connects the pier to the truss. Using a painstakingly coordinated cast of hydraulic rams and jacks, crews pushed about 10 million lb of bridge section westward. The feat frees up an expansion joint

After five years and six miles of track and tunnel construction, the $898-million Metro Gold Line Eastside Extension project is nearing completion without a single lost-time injury in more than 4 million work hours. Photo: The Los Angeles Metro Massive Los Angeles rail project nears completion with no lost-time injuries so far. “We think this is some sort of a world record,” says Mike Aparicio, project manager for Eastside LRT Constructors, the design-build joint venture of Washington Group International, Obayashi Corp. and Shimmick Construction Corp., which holds the $600-million construction contract. “We have not been able to find [any other

The Missouri Highways and Transportation Commission selected KTU Constructors to replace 554 bridges across the state over the next four years under a $487-million design-build contract. Combined with another 248 bridge projects the Missouri Dept. of Transportation has awarded, Missourians are scheduled to be be driving across 802 new bridges by Oct. 31, 2014. The full program is expected to cost $700 million. MoDOT will sell bonds to finance the program, repaying them with annual payments of $50 million it receives from the federal bridge funds each year. Over the life of the project, that method is expected to save

A team led by Parsons Brinckerhoff and HOK bested four other high-profile groups to design a $180-million regional intermodal transportation center in Anaheim, Calif. The project is the first of what could be a three-phased effort for expanded regional rail service and a possible high-speed line to Las Vegas. The Anaheim City Council selected the team on May 26 for the $24.3-million design contract over teams led by RMJM, linked with Gehry Partners and AECOM; Parsons Corp. and Skidmore, Owings and Merrill; Pelli Clarke Pelli Architect and AAI Architects Inc.; and Foster + Partners and Gruen Associates.

In a rapid-fire series, President Barack Obama and Energy Secretary Steven Chu announced $773 million in funding under the American Reinvestment and Recovery Act for geothermal and solar-energy projects. On May 27, Obama announced $350 million for geothermal demonstration projects, research and development, and other geothermal initiatives. He also announced $117.6 million for solar technology development and deployment. On June 1, Chu said the Energy Dept. would invest $156 million in combined heat and power, district energy systems, waste-energy recovery systems and equipment; $50 million in energy efficiency for information and communication technology; and $50 million for advanced clean-energy materials

Rocky Mountain Power Inc. has applied to the Nevada Public Utilities Commission for a permit to build a segment of PacifiCorp’s 1,900-mile, $6-billion Energy Gateway Transmission Expansion Project. On May 21, PacifiCorp’s Salt Lake City-based division applied to build 77 miles of 500-kV transmission and ancillary facilities in Clark and Lincoln counties, Nev. Portland, Ore.-based PacifiCorp’s Energy Gateway, announced in 2007, is envisioned as a network that will branch to the west and southwest from Windstar substation near Casper, Wyo., with north-to-south links between the branches in Utah and a separate segment between Washington and Oregon. The Federal Energy Regulatory

A self-described “geothermal wildcatter” from Oregon intends to use a waste byproduct of oil and gas production to generate electricity along the Texas coast. Geo Texas Co., a Eugene, Ore.-based startup company led by geothermal pioneer Steve Munson, will pay Texas $386,000 a year for leases up to 30 years on 128,758 acres of state land off the coasts of Brazoria and Matagorda counties, near Galveston, to produce geothermal energy. The company will pay more if it produces energy. Munson plans to build a 20-MW, $50-million demonstration plant on land within two to three years. Research has uncovered an estimated
