Crest Gates

Construction and commissioning support for repair of a crest gate.

Bergmann supported a hydropower facility's efforts to return a crest gate to service. This gate was damaged by excessive ice.

Bergmann provided design and construction support for gate and gate operating cylinders repairs and concrete repairs to the apron and piers. We designed modifications for an existing cofferdam and prepared bid packages for procurement of that work. Bergmann also developed a commissioning procedure and provided on-site commissioning support.
