Spitallamm dam
Grimsel, Switzerland
Doka makes a lasting impact on Swiss energy future
The 1,900-meter high alpine construction site presents a demanding work environment, primarily because of difficult weather conditions and logistical challenges. The new Spitallamm dam is being constructed in front of the existing dam, which will be retained and flooded later. Operated by energy provider Kraftwerke Oberhasli AG, the new dam has the same crest height of 113 meters as the existing wall, and offers the possibility of being raised in a later phase to enlarge Lake Grimsel. A highlight is undoubtedly the sturdy dam formwork, including safety platforms and the preassembled gallery formwork, which formed the complex network of control walkways inside the dam. Our ability to support the entire project from formwork and planning to digital services is a real benefit for the customer as everything is supplied from a single source.Press Release
