Stettlen, Schwandihof WL

Short description

With the "Schwandihof property", Bernapark AG created a new quarter on an old farm site, which combines living, work and leisure in one place. We carried out the civil engineering work for this project. These were carried out in various stages.

The project

First, exploratory excavations were carried out to determine the location of the existing utility lines. This was followed by excavation work for the district heating, water, wastewater and electrical lines. In some cases, this required the prior demolition of pavement or concrete slabs as well as underground concrete walls and sewers. Where necessary, trenching was used. Pipeline construction also included the construction of various manholes (ES, KS and SS) with DN up to 1.0m, as well as the connection to existing pipelines and the insertion into the buildings. The latter was done by means of core drilling where necessary. Finally, the pipes were encased and the trenches filled and compacted. Inside the building, the pipelines for various media were installed.
