ACEC Engineering Excellence 2017: 90-Inch Water Main Hot Tap & Line Plug in Des Plaines, IL

Monday, July 17th, 2017
2017 ACEC Engineering Excellence Awards

A colossal 90-inch water transmission main was completely relocated to accommodate the rebuilding of the Jane Addams Memorial Tollway, while incredibly maintaining water service to 500,000 residents. The project team designed, tested, and constructed a unique thrust restraining system to absorb the massive forces generated by the risky hot tap procedure—where two pipes are connected without emptying pipe contents. The system safely absorbed the high pressure force when water was diverted into the bypass section. It allowed a critical water supply to be preserved, the construction schedule to be reduced by a year, and renovation of the Tollway to proceed.

Engineering, Inc. - July/ August Cover

Despite a never-ending legislative to-do list, regulatory reform and the nation’s crumbling infrastructure are emerging as key policy priorities for Congress and the new presidential administration. In an exclusive interview with Engineering Inc., Sen. John Barrasso, R-Wyo., discussed his vision for infrastructure investment, regulatory reforms and energy legislation. “I am working with the new administration to address our infrastructure priorities and find fiscally responsible ways to start building,” says Barrasso, chairman of the Environment and Public Works Committee.

ACEC Engineering Excellence 2017: 130th & Torrence Grade Separation in Chicago, IL

Tuesday, July 11th, 2017
Alfred Benesch & Company, 130th & Torrence Grade Seperation

One of Chicago’s most noted traffic bottlenecks has been transformed into a smooth-flowing multi-tiered interchange that is also helping spur development of the nearby Chicago Manufacturing Campus. Each day, more than 38,000 vehicles, 50 freight trains and 41 passenger trains used the intersection, creating a crowded logjam. Further complicating the project was its close proximity to an automotive assembly plant, a railroad mixing yard, a residential area, and protected marsh area. The project realigned roadways and added six new bridges, including a 4.75-million-pound steel railroad truss bridge assembled in a nearby staging area then transported in just four hours to its permanent location.

Innovative upgrades helped double this waste water plant’s wet-weather processing capacity to 720 million gallons per day, while increasing sediment and grit removal to 92 percent and reducing odor. To reduce discharges into the East River, the project team utilized advanced 4D modeling technology to deliver four new treatment components— totaling $1.3 billion—and inspected the interiors of eight, 140-foot-high egg-shaped anaerobic digesters that sit atop the plant. They also implemented a biogas program that is expected to heat nearly 5,200 homes and reduce annual greenhouse gas emissions by more than 90,000 metric tons by the end of this year.

ACEC’S ENGINEERING INC. — Ranking Sustainability: What U.S. Cities Can Learn From European Peers

Thursday, June 29th, 2017
2016 Arcadis Sustainable Cities Index

What about North American cities? The index found they have a lot to learn from their international peers. Vancouver was the continent’s leader at 23rd in the overall ratings, while U.S. cities failed to enter the top quartile. The closest contender was New York City at 26th place…Infrastructure differences help explain why European cities outpaced U.S. and Canadian counterparts. Many European urban centers were settled before the automobile age and, as a result, are densely settled and supported by well-established public transportation systems. However, many American cities outside the Northeast grew with automobiles in mind. “Carcentric designs can lead to urban sprawl and a large carbon footprint, with enormous costs,” Dalkmann says. “Those are fundamental challenges for U.S. cities in terms of sustainability.”

Sellwood Bridge Replacement in Portland, OR

A picturesque, three-arch bridge replaces a deteriorating 1925-era structure that was threatened by an encroaching hillside. The project team incorporated advanced seismic resilient bridge components and innovative landslide mitigation systems to stabilize the hillside. They also trimmed a year off the construction schedule by shifting the original steel deck truss to one side using hydraulic jacks, allowing the bridge to remain in service during construction.

Guest on The Infra Blog: Michael McArdle, Chief Development Officer, VHB

Mike McArdle, VHB Corporation, on The Infra Blog

“I commend the Administration for talking about a trillion dollars, but right now they’re only talking about putting $200 billion of public money up and the rest coming from other sources in the private sector. And while there’ve been some successes of that in this country as well as overseas, I don’t think we can afford to wait for a financing program to fully mature before we make significant infrastructure investments. It has to be done now; the federal government has to recognize that they need to spend this money. They can’t continue to hold the dollars hostage going forward.”
