The sanitary installations were modernised at the former Kursaal Hotel Allegro - now Swissôtel Kursaal Bern. For example, walk-in showers were installed. During the project, the greatest challenges of the project were the restricted preparation time, the high demands for precision and ensuring the hotel's operation could continue to run smoothly.
The Swissôtel Kursaal Bern is a venerable institution and offers visitors a beautiful view of Bern's old town. In addition to the casino and restaurants, the congress centre on the Kornhausbrücke also houses the Hotel Allegro, which opened in 1998.. The 171 hotel rooms were renovated in stages up until the end of 2020. The Bouygues Energies & Services team in the Bern region was responsible for renovating the sanitary facilities.
