LZK-Project

Cost optimization for sustainability: With knowledge of life cycle costs, ASTRA can optimize the costs of building and maintaining national roads over their entire service life. This enables better, economically sustainable use of the financial resources available. Together with ASTRA, R+R is preparing documentation that describes the method for estimating and applying life cycle costs for the structural infrastructure from the operator's perspective. The focus is on the planning level and applicability by project managers and project teams.

N01.22 Motorway section Schönbühl – Kirchberg, Lindenrain rest area upgrade

The service building at the Lindenrain motorway rest area has been equipped with a new toilet module made of chrome steel; construction was completed at the end of 2023. The new toilet module offers better protection against vandalism, and it will be possible to continue its use in the event of a future replacement of the service building. R+R supported the Federal Road Office’s overall project manager in project planning and execution.

ERTMS Netherlands

Other countries, same problems: Modern railway technology requires time and money to implement. Jost Lüking was member of a team of six European experts on the ETCS train control system who assessed the status of the national ETCS program for the Dutch Parliament in mid-2023. Our Second Opinion formulated recommendations on program governance and management, on the technical, spatial and temporal scope of the program, on system integration and integration management, and last but not least on program costs and their current forecast. The Dutch Ministry of Infrastructure and Waterways published the Second Opinion at the beginning of November.

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.

CORRECTIVE MAINTENANCE PROJECT A1 EFFRETIKON – OHRINGEN, TÖSS BRIDGE

The 162 m long Töss Bridge between Winterthur Töss exit and Winterthur Wülflingen exit was renovated between March 2014 and July 2015 under continuous operation. The renovation of the bridge is one of a total of eight preliminary measures that have been separated from the more comprehensive corrective maintenance project Effretikon – Ohringen by the general project management team of the Federal Roads Office and which are being implemented in advance.

The approximately 12 kilometres long motorway section of the A1 between Effretikon and Winterthur Ohringen was built more than 40 years ago and is to be extensively renovated from 2017 until 2021. The refurbishment of the Töss Bridge forms part of this corrective maintenance project of the Federal Roads Office, but had to be tackled in advance due to the poor structural condition of the bridge. Construction work was carried out without reducing the number of available lanes, although the construction site required the reduction of lane widths according to the respective standards and a speed limit of 80 km/h instead of 100 km/h. Maintenance work comprised structural improvements of bridge and abutments, the replacement of expansion joints and bridge bearings, concrete refurbishment as well as the renewal of sealing and pavement.

Throughout all phases of the Töss Bridge renovation, R+R provided support and assistance to the general project management team and was involved in construction site supervision. Tasks notably included monthly project controlling with supervision of costs and work progress. Thanks to favourable weather conditions, considerate planning and work execution in two shift operations, the Töss Bridge could be reopened to traffic nearly a month earlier than planned.
