A1, Extension of the Zurich Northern Bypass
The main construction work for the Weiningen motorway exit and the covered road section will start on August 16, 2021. The Weiningen exit will be relocated and moved around 200m closer to the Limmattalerkreuz junction. In addition, all three Gubrist tunnel tubes will be extended by a new 100m covered motorway section. This will reduce the noise and pollution levels of the adjacent residential areas. From mid-August, the top pavement layer of the roadway in the new third Gubrist tunnel tube will be installed over a period of approximately 3 weeks. Thus, most of the construction work will have been completed. In autumn 2021, installation of the traffic control and safety systems for the third Gubrist tunnel tube will start.
R+R has moved
Since June 1, 2021, the R+R offices have been moved into new premises on the 6th floor of the Duplex building in Baden at Brown Boveri Strasse 12. As before, we are still at a very central location within the city of Baden. As you notice, we also took the opportunity to update our website. We hope you enjoy the new content, and we look forward to welcoming you in our new offices at the next opportunity.
Oslo T-bane: CBTC project reaches important milestone
Oslo has an extensive metro network, the oldest in Scandinavia. Five lines serve 101 stations, and, in the central section, trains run every minute. Today, three different interlocking technologies are in use, some of which are already quite old. Over the next few years, operations will be converted to the communication-based train control system CBTC. At the beginning of February, four suppliers submitted initial offers for the system’s introduction and operation in the following twenty-five years. R+R supports the customer Sporveien with the evaluation of offers and the upcoming negotiations.
ETCS introduction in Finland
As part of the Europe-wide introduction of the interoperable train control system ETCS, Finland is examining the right strategy for the country. Fintraffic Rail develops pioneering digital solutions under the “Digirail” label. By the beginning of 2020, a wide range of variants had been presented, for which R + R provided rough estimates of the life cycle costs. In the meantime, Fintraffic Rail has derived an ideal solution and has examined it in depth. At the beginning of 2021, R + R developed a refined cost estimate and compared it with the costs of a fallback solution. In addition, R + R supports the assessment of cost uncertainty and the cost consequences of risks.

A1 ROADWAY MAINTENANCE PROJECT BRÜTTISELLEN INTERSECTION
The Brüttisellen intersection links the A1 with the A53. The heavy volume of traffic leads to regular jams. Due to the poor condition of the two dual bridges, repairs are required in advance of the comprehensive renewal of the Zurich East – Effretikon section.
The Brüttisellen intersection was built in 1974. The Haldenbrücke bridge and the underpass for the connecting road are reinforced concrete composite bridges with lengths of 184 meters and 86 meters respectively. The choice of the foundation in difficult, non-homogeneous subsoil deliberately took account of differences in the settlement of the abutments and supports. The settlement differences are compensated by removing washers. For this compensation to remain possible, the bridges had to be raised to their original levels in 2012/2013. Due to the high volume of traffic, the condition of the two bridges requires reinforcements for the steel girders and total renewal of the corrosion protection. Traffic safety was improved by adjustments to the traffic routing in the area of the entrance to the A1 in the direction of Zurich.
The refurbishment work was brought forward in response to the results of the structural engineering investigations. The comprehensive repair and renewal of the Zurich-East to Effretikon section of the national highway is scheduled between 2025 and 2030. R+R provided assistance for the overall management of the project by the Federal Roads Office (FEDRO), Winterthur Branch, by way of client support during the implementation of the project. Key aspects of this support included procurement, meetings and project controlling. R+R was also entrusted with quality assurance by the client. High-quality documentation and professional dealings with external parties, together with plans and reports that are error-free and consistent insofar as possible, are prerequisites for the efficient provision of services, a high quality of execution and minimal additional costs due to changes and adjustments to specified requirements for building contractors.
