Kleinfelder received the Gold Award for Social, Economic and Sustainable Development from the American Council of Engineering Companies, Washington Chapter for its work in redeveloping the Snoqualmie Falls hydropower project.
The architecture, engineering and science firm said it won the award for “demonstrating advanced technical expertise” throughout the three-year project, which included the renovation of two powerhouses, preservation of six historical buildings, and development of recreational site enhancements.
Plant 1 of the Puget Sound Energy-owned project was opened in 1898, at which time it was the world’s first completely underground powerhouse. Plant 2 was opened in 1910 along the Snoqualmie River below the falls.
“Kleinfelder was enthusiastic to work on this project because of its complexity, diverse construction techniques and commitments to the historic power plant and the surrounding environment,” senior project manager Rick Della said. “For Puget Sound Energy, the challenge was to ensure that the plant continued to provide clean, renewable power, protect the historic structures, and ensure that visitors can enjoy the falls and surrounding environment while meeting an accelerated 36-month schedule.”
HydroWorld.com reported that the project reopened in April with a total installed capacity increased to 54 MW.
