Three HDR Washington Projects Headed to National Engineering Competition

Three HDR-led projects have earned honors from the American Council of Engineering Companies of Washington and will advance to the organization’s national competition. Winners will be recognized at the American Council of Engineering Companies Engineering Excellence Awards banquet in Washington, D.C., held in April.

The South 200th Link Extension project for Sound Transit is the first light-rail extension south of the initial line and first transit station in the Pacific Northwest to be LEED gold certified. It provides service from Sea-Tac Airport to South 200th Street via a 1.6-mile elevated guideway and offers a lifeline to the region’s job hubs, universities, medical facilities, and arts and entertainment resources. Through extensive community outreach by Sound Transit and its partners, the project engaged residents and businesses throughout SeaTac and the surrounding cities. Originally slated to open in 2020, the project opened four years ahead of schedule and $40 million under budget.

The Factoria Recycling and Transfer Station project for the King County Solid Waste Division is a new 80,000-square-foot facility that can process more than 225,000 tons of garbage, recycling, yard waste and household hazardous waste per year. Anticipated to be LEED gold certified, it’s a model for sustainable transfer station design. It uses 40 percent less electricity than similar facilities, and its rainwater catchment system is anticipated to save 1.3 million gallons of potable water per year. The flat-floor design allows for easier garbage unloading, flexible traffic flow and shorter customer wait times. With this transfer station handling more than 16 percent of King County’s solid waste, closing for construction was not an option. Keeping the previous facility open during construction required excavating 300,000 tons of soil, building a temporary 40-foot-tall and 300-foot-long shoring wall and creating four different temporary traffic patterns through the construction zone.

The Wells Hatchery Modernization project for the Douglas County Public Utilities District brought this Columbia River hatchery up to modern code, fish culture, and biosecurity standards after 50 years of operation. The new hatchery ensures the facility will reliably meet future fish culture needs in a bio-secure fashion. New circular rearing tanks, automated adult fish crowding and handling systems, and water to water fish transfer methods not only cut down on required staff hours and reduce stress on fish, but allow staff to focus on the facility’s primary goal – raising healthy fish. With both ground water and surface water available during rearing cycles, Wells Hatchery is in a unique position to utilize the water best suited for the life stage of the fish. The entire hatchery water and alarm system is integrated into a SCADA system with human interfaces in multiple locations on site. A carefully orchestrated construction schedule ensured the hatchery remained in full fish production operation during the three-year construction process. This ensured that the District’s mitigation goals were met and vital conservation and harvest hatchery programs continued throughout construction.
