WASHINGTON — The Copperhill Watershed Restoration Project in Ducktown, Tennessee, has won the 2020 “Grand Conceptor” Award, signifying the year’s most outstanding engineering achievement, in the 53rd Annual Engineering Excellence Awards (EEA) — a national juried competition sponsored by the American Council of Engineering Companies (ACEC).

Traditionally an annual black-tie dinner and awards show, the event attracted more than 650 viewers Tuesday during its first-ever Virtual Engineering Excellence Awards Gala. Hosted by comedian Ross Shafer, the Gala honored 203 preeminent, global engineering achievements.

“Our member firms contribute amazing value to society. They improve our environment, design innovative spaces that sustain our social interactions, and develop new ways to move, conduct commerce and create new opportunities for economic development. Their work makes our modern life possible and they deserve to be recognized for it,” said Linda Bauer Darr, president and CEO, ACEC. “I am pleased we could keep the tradition of the annual Engineering Excellence Awards going this year with a virtual broadcast of the event.”

Designed by Barge Design Solutions in Nashville, the 20-year restoration project transformed a 50-square-mile site, severely damaged from more than a century of logging, mining, and acid production, into a lush, clean, and natural wonderland, where residents now enjoy fishing, swimming, and hiking. A video showcasing the project can be seen here.

Restoration efforts included disposal of mining waste, construction of clean-water diversions; re-establishment of natural, healthy communities of aquatic insects; and construction of new contaminant-filtering wetlands. Before the restoration, the contaminated site was one of only two manmade features astronauts could see from space, along with the Great Wall of China.

The project joins a prestigious list of previous Grand Conceptor Award winners, including the Alaskan Way Viaduct Replacement (Seattle, 2019); the Bayonne Bridge: Raising the Roadway Project (Bayonne, NJ/Staten Island, NY, 2018); the SR 520 Floating Bridge Replacement (Seattle, 2017); and The San Francisco Air Traffic Control Tower (2016).
