Alpe Gera Dam

The Alpe Gera Dam is a gravity dam on the Cormor River in a lateral valley of Valmalenco 17 km (11 mi) northeast of Sondrio in the Lombardy region of Italy.

It is 174 m (571 ft) tall and supports a 35 MW hydroelectric power station.

Instead of concrete being poured into conventional monoliths, it was poured in layers with a lean mix.

Next, the concrete was settled with immersed vibrators and then contraction joints were cut into the layer.

These methods were not only cost-saving but instrumental in the development of roller-compacted concrete in dam construction.
