Bonneville FGE Gatewell Improvement

The project included concrete demolition via hydro-demolition, and installation of a new concrete corbel in the Gatewells of Powerhouse 2 intake bays. The work was performed 60 feet below the intake deck, and above another 60 foot of free distance to the intake floor, requiring an engineered platform to be erected and special considerations for confined space, crane placement, and access. The work was completed in April 2021, during a short 6 week Unit Outage coordinated with the BPA.
