A1 expansion northern Zurich bypass

The commissioning of the third tube of the Gubrist tunnel has been postponed until spring 2023 due to the current global economic situation (Covid).

During the night of April 22/23, 2023, there will be a "silent opening" of the third tube to regular traffic. A public festival and the authorities’ event are expected to take place in mid-April 2023.

In early May 2023, the renovation work of the existing second Gubrist tube will start. Westbound traffic (direction Bern) will be accomodated on two lanes in the new third tube, while eastbound traffic (direction St. Gallen) will occupy two lanes in the first tube.

RESEARCH PROJECT VSS 2011/705: LIFE CYCLE COSTING FOR MANAGING ROAD MAINTENANCE

R+R has carried out a research study on behalf of the Swiss Association of Road and Traffic Professionals (VSS) on Life Cycle Costing in road maintenace. The report represents a general guide and manual for improved maintenance strategies, providing basic knowledge as well as specific instructions.

Das InstruLife Cycle Costing (LCC), as a tool to minimise life cycle costs, is not restricted to mere analysis, but also includes a design task. An iterative process leads to the definition of optimal system boundaries (maintenance strategy, construction variant, etc.) resulting in minimal costs over the entire life cycle of the road infrastructure. Function and benefits are predetermined.

The research study presents a process sequence that highlights the individual elements and steps belonging to a comprehensive LCC. Irrespective of the actual decision-making scenario, this process sequence is the same for all subsystems in accordance with SN 640 900. The specific method of evaluation, the period under observation and the risk analysis are to be determined on a situational basis.
