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 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

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 Engineering Excellence 2017: Sellwood Bridge Replacement in Portland, OR

Tuesday, June 20th, 2017
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.
