Summary
Machine-generated summaryThe buyer is seeking a contractor to renovate the fish downstream migration structure at the Maigrauge dam in Fribourg, Switzerland, as required by authorities restoring fish migration. Works include a new water intake, adaptation of the existing bank-side downstream migration device, new hydraulic structures and interventions on the dam and power plant. The existing hydropower facility remains in operation throughout the works, so contractors need proven experience in hydraulic works, civil engineering on existing structures and live-site construction, with high safety and risk management standards. Some works will be carried out in water using a temporary cofferdam while keeping the lake level and main intake operational. No value, date or procedure details are stated in the description.
