Successful installation of a DN 350 culvert under Grünaustrasse in Buchs SG

In October 2024, BRUGG Pipes realised a technically challenging project together with VfA Buchs: the underground installation of a DN 350 pipe (culvert) under Grünaustrasse. The measure was necessary in order to adapt the heat supply to the waste incineration plant (WIP) to the changed structural conditions.

Precise planning and implementation

The project was necessitated by the new building on Grünaustrasse, which blocked the existing pipe route. An above-ground solution was not practicable, which is why the pipeline was routed through the Giessen, a local body of water. Extensive technical preparations were made to ensure that the watercourse crossing was safe and efficient.

Innovative technology in use

Two mobile 35-tonne cranes were used to position the culvert. This solution enabled the pipeline to be positioned with millimetre precision under challenging conditions. The logistical effort and the high level of precision with which the work was carried out illustrate the high standards of the project and the technical expertise of everyone involved.

Customised solutions from BRUGG Pipes

BRUGG Pipes supplied PREMANT pipe systems, which were fitted with INDUCON couplings for maximum tightness and durability. In addition, the company supported with technical engineering and precise planning, resulting in maximum operational safety and energy efficiency.

With this successful project, BRUGG Pipes is emphasising its role as a reliable partner for complex infrastructure projects in the field of heat and energy supply.
