France’s Seine River Basin agency seeks bids to rehabilitate the bottom outlet valve of the 5.9-MW Panneciere hydroelectric project on the Yonne River in France’s Nievre Department. Bids are due February 6.

Hydropower engineer Hydrostadium pre-qualified firms in 2012 to construct cofferdams and refurbish a large valve at Panneciere, which was built in 1949 for flood control of the Seine. French contractor Rouby subsequently received a contract to refurbish the valve of the project’s compensating basin and design and construct upstream and downstream cofferdams.

The Institution Interdepartementale des Barrages-Reservoirs du Bassin de la Seine (IIBRBS) now seeks bids for an underwater cofferdam, rehabilitation of hydro-mechanical works of the bottom outlet valve chamber, cleaning of the upstream gallery and sealing of plugs for valve rehabilitation.

Tender documents may be obtained from the second address below. Bids, in French, are due by noon February 6 to the second address below.
