The scaffolding platform reaches first across the draft tube from the door and then builds out geometrically from the center structure. The hexagonal structure connects to anchor brackets on the draft tube wall and then supports a deck surface, which will accommodate scaffolding to provide safe access to the areas where cavitation impacts the turbine blade and the draft tube liner. Project crew members Mike Schnetzer and Dale Stibral place the scaffolding platform in the draft tube beneath the Kaplan Turbine at Gavins Point Dam.
