HDR Project Earns Top Montana Engineering Honor

One of three HDR projects to move on to national engineering competition

Three HDR-led projects have earned honors from the American Council of Engineering Companies of Montana and will advance to the organization’s national competition. One of them, the Basin Creek Water Treatment and Ancillary Facilities project in Butte-Silver Bow, received the Grand Award — the top honor in the state. The Capitol Interchange-Cedar Interchange in Helena won the Honor Award in the Structural Systems category. The Compressed Natural Gas Fueling Station project in Billings won the Honor Award in the Energy category. HDR was also on the team for the South Reserve Street Pedestrian Crossing project in Missoula, which won the Honor Award in the Transportation category.

The Basin Creek project involved designing and constructing a new water treatment plant at Basin Creek. Surface water from the Basin Creek Reservoir was one of the purest water sources in Montana and did not require treatment until it tested above maximum contaminant levels for disinfection byproducts in 2011. The resulting $30 million facility uses a cutting-edge ceramic membrane system, widely used in Japan and Europe but the first of its kind to be installed in the United States. The treatment plant includes several engineering innovations that save money and improve raw water recovery to an incredibly efficient 99.95 percent, while blending into the scenic landscape south of Butte.

The Capitol Interchange-Cedar Interchange project involved reconstructing Interstate 15 between these interchanges in Helena. The focal point was replacing a pair of bridges that span the Montana Rail Link rail yard. The new bridges are approximately 800 feet long and span 14 railroad tracks. Maintaining traffic during construction was critical due to traffic volumes and weaving movements associated with the closely spaced interchanges. Developing a design that could be built within the short Montana construction seasons while minimizing impacts to the rail yard were critical to the success of the project.

The Compressed Natural Gas Fueling Station project made it possible for the city of Billings to transition its solid waste collection fleet vehicles from diesel to compressed natural gas, converting methane from the city landfill to the CNG used in the collection trucks. CNG fueling stations are not a “plug and play” application; each site has unique challenges including space, proximity to fuel source, electricity availability and designing and conveying the pressurized gas. In Montana, it also means designing to a wide range of temperatures. The result is Montana’s first municipal CNG fueling station, with equivalent fueling costs of approximately $.77 per gallon of fuel.

The South Reserve Street Pedestrian Crossing project provides safe pedestrian/bicycle access across Missoula’s busiest street via an iconic pedestrian bridge. HDR provided engineering and architectural design for the main span over Reserve Street, in addition to lighting design.

Projects advancing to the national competition will be judged in spring 2018, and winners will be recognized at the American Council of Engineering Companies Engineering Excellence Awards in Washington, D.C., in April.
