510 Meter Road Rehabilitation

The Jakob-Stämpfli-Strasse rehabilitation project in Biel, Switzerland, involved extensive roadworks over a length of 510 meters. New sidewalks were constructed on both sides, the entire drainage system was renewed, and the foundation and edge trims were replaced. Additionally, various catenary poles were updated, and four bus plates for the public transport company were demolished and rebuilt. As part of this project, the electricity network and public lighting system were also extended, and 80 tree planting quarters were constructed and covered with cast grates.

Staged Execution for Accessibility

Work was executed in stages, ensuring continuous access to the public transport, two lanes of traffic, and accessibility to two separate large construction sites. Key materials, including base and surface courses, were laid on both the sidewalk and road surfaces. The project's logistics were demanding, necessitating the coordination of material handling, deliveries, removals, and installation changes outside of the traffic areas.

Inner-City Challenges Overcome

This project faced significant challenges due to its inner-city location, which included maintaining public transport operations and ensuring accessibility to secondary construction sites. Despite these hurdles, the project was successfully completed between January 2017 and August 2018. Implenia Switzerland Ltd served as the sole contractor with general management by Schmid & Pletscher AG, meeting a construction volume of 2.17 million CHF.
