Completed construction projects

New boatyard hall on Lake Thun

After a good year or more of building work, on 11 January BLS officially opened its new boatyard facility on the Lachenkanal. Thanks to this newly constructed facility, which was largely financed by the canton of Bern, the future of boat operations on Lake Thun has been guaranteed.

The old boatyard hall, which was 110 years old, was no longer technically fit for purpose and needed to be replaced for safety reasons. With the newly built hall, BLS Navigation services have been guaranteed. The company will now be able to maintain its Lake Thun fleet of vessels in the hall’s dry dock facility in a legally compliant and efficient manner.

Key dates, facts and figures

The canton of Bern provided much of the finance for the construction of the new boatyard facility, after the cantonal parliament had unanimously agreed to the investment project, worth CHF 12.8 million, in early 2015. “With the completion of this once-in-a-lifetime project, the Bernese Oberland will continue to be able to rely on navigation services, which are important both for tourism and the economy,” noted Barbara Egger-Jenzer, Member of the Governing Council, during the opening ceremony.

The new dry dock facility will make it easier for workers to maintain the fleet of boats. Whereas previously the boats, which can weigh up to 444 tonnes, had to be lifted out of the water in the old boatyard, in the new facility the water is simply pumped away to expose the underside of the boat for necessary repairs. This significantly simplifies the tasks involved in maintaining the below-water sections of the boats. Thanks to its new workshops, BLS is creating a modern working environment for its employees. The sustainability of the Swiss wood construction is further enhanced by the addition of a photovoltaic solar power system on the roof, which generates approximately one-third of the building’s total energy requirements.
