Forggensee Reservoir Dam Reopens

 

After a total construction time of only 16 months, during which all participants worked at maximum capacity, remediation of the Forggensee reservoir dam in Rosshaupten was successfully completed in July 2019. After completion of the new street along the dam crest (including walking and biking paths) and other construction projects, the Rosshaupten reservoir dam was re-opened during a festive ceremony.

Uniper Kraftwerke GmbH commissioned Bauer with execution of the 13,500 m² diaphragm wall to seal the dam. Though this project posed a particular challenge related to the diaphragm, Bauer carried out the construction work for the diaphragm wall seven days a week in day and night shifts – in other words, 24 hours a day. To prepare the power plant and the flood control for the future, the dam seal was renovated by BAUER Spezialtiefbau GmbH from March 2018 through April 2019.

The fifth-largest lake in Bavaria and the largest reservoir in Germany in terms of area, it also generates electricity and provides flood control when the snow melt begins in the Alps.
