PPM was responsible for building a temporary coffer dam to allow repairs to the existing Hebgen Dam. This involved dewatering around the work zone to facilitate safe and efficient repairs. Our team conducted structural repairs to the existing dam infrastructure, including the installation of new structural materials and ensuring the dam would remain fully operational for decades to come. Given the project’s location in a sensitive area, PPM worked closely with environmental consultants to ensure minimal environmental impact throughout the repair process. Throughout the project, safety was the number one priority, with stringent safety protocols in place to protect workers, wildlife, and the surrounding community.
