EP Hagnau – Augst N02
Within the Hagnau – Augst motorway maintenance project, structural changes to the western tunnel portal (direction Basel/Germany) have to be carried out to enable longitudinal ventilation in both traffic directions. We are pleased that the plans for the extension of the western portal of Schweizerhalle tunnel have officially been approved. This allows us to finalise the detailed design and approach the contractor submission process according to our project schedule.
N06.28 NEB EM Lyss Süd – Schönbühl
We are pleased to provide managenent support and construction site management for the N06.28 NEB EM Lyss Süd - Schönbühl motorway maintenance project on behalf of the Federal Road Authority’s Thun branch. The project includes replacement of the pavement as well as extensive measures on the engineering structures. The construction work is scheduled to be carried out between 2025 and 2027.
A1 Opening day of the Gubrist tunnel
Another bottleneck removed: On July 3rd, Federal Councilor Albert Rösti officially opened the new third tube of the Gubrist motorway tunnel, in the presence of representatives of the canton and city of Zurich as well as the local communities and members of the project team. Now three westbound traffic lanes are open to road users travelling in the direction of Bern.

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.
