ACEC’S ENGINEERING INC. — Innovations in Airport Design - Quarry Lake

Since early 2016, a new 3,600-ton capacity geothermal system has been providing cooling for the entire terminal building at the Nashville International Airport, significantly reducing the facility’s use of both electricity and water. The nearly $10.4 million project finished three months ahead of schedule and under budget.

The Enduring Legend of Gridlock Sam: Sam Schwartz addresses employees at the company

“Gridlock Sam” Schwartz has always had an outsized presence in his endeavors. “He is, inarguably, the most beloved transportation engineer alive,” says Charles Komanoff, a New York City transport economist, who then adds with a smile, “Admittedly, there’s not much competition.”

ACEC’S ENGINEERING INC. — Higher and Higher: Member Firms Push the Limits to Design Effective and Attractive High-Rise Structures

Monday, July 31st, 2017
Seoul, South Korea: Supertall Skyscraper

In a creative blend of old and new, the fabled Steinway Hall on New York’s West 57th Street will soon begin a new career, its atrium serving as the elegant main entry for a supertall high-rise now under construction on the adjacent site. Featuring progressively greater setbacks on its northern face for a feathered rather than stepped profile, the new 1,428- foot tower’s glass curtain walls will offer unparalleled views of Central Park to the north and the Manhattan skyline to the south. Hearking back to the quality and detail of historic New York towers, the shear walls on the east and west are being clad with a custom-cast terra cotta, bronze filigree and glass façade.

ACEC Engineering Excellence 2017: Franklin Avenue Bridge Rehabilitation in Minneapolis, MN

Monday, July 24th, 2017
HNTB Corporation, Franklin Avenue Bridge Rehabilitation

Major restoration of this historic five-span arch bridge over the Mississippi River would normally require a two-year closure, yet the span was reopened to traffic after just 116 days. With the renowned 1923-era Minneapolis landmark needing extensive structural rehabilitation, the project team designed and fabricated numerous bridge elements and systems, including deck panels, rail panels, cap beams, and ornamental railing panels, prior to closing the bridge to traffic. The design also included polished stainless steel plates embedded in the underside of the precast deck panels to reduce the number of needed expansion joints. The project is a model for reconstructing a bridge within a short time frame.

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

Monday, July 17th, 2017
GRAEF - TDW Services, Inc., 90-Inch Water Main Hot Tap & Line Plug

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.

ACEC’S ENGINEERING INC. — Wyoming Republican Senator Seeks Infrastructure and Regulatory Reform

Wednesday, July 12th, 2017
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.

ACEC Engineering Excellence 2017: Newtown Creek Waste Water Treatment Plant Upgrade in Brooklyn, NY

Monday, July 3rd, 2017
Michael Baker Int’l; CB&I; Gannett Fleming (Joint Venture), Newtown Creek Waste Water Treatment Plant Upgrade

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.”

ACEC Engineering Excellence 2017: Harry Tracy Water Treatment Plant in San Bruno, CA

Tuesday, June 27th, 2017
Kennedy Jenks Consultants: Harry Tracy Water Treatment Plant

Combining advanced civil and structural engineering innovations, the project team designed an 11-million-gallon reservoir that will help a nearby water treatment plant quickly restore operations in the wake of a major earthquake. The massive above-ground, concrete reservoir includes a “tank within a tank” design, with an outer 3-million-gallon chlorine contact raceway for water treatment surrounding
