Stantec experts discuss the challenges and successful completion of adding hydropower to the Red Rock Dam in the latest issue of Deep Foundations

The Red Rock Hydroelectric Project received DFI’s Outstanding Project Award (OPA) for 2021 in part due to the extensive retention systems put into place to maintain the integrity of the existing flood control dam. As owner’s engineer and designer on the project, Stantec experts Rachael Bisnett and Tom Andrews authored this piece in Deep Foundations Magazine to highlight the construction challenges.
