Oslo T-bane CBTC-Project

After two tendering rounds with, at first, four tenderers, Sporveien, the operator of Oslo City’s public transport system, awarded the contract for equipping the metro with a CBTC system to Siemens. R+R has edited the price formats, evaluated the commercial tenders, and supported the negotiations. At the same time, in the Datalink sub-project, Sporveien procures the communication services and the necessary upgrading of the communication infrastructure.

A1, Extension of the Zurich Northern Bypass

Twenty years ago, a serious fire disaster occurred in the Gotthard motorway tunnel. To commemorate this event, the «SRF Aktuell» TV program has produced a report on road tunnel safety in Switzerland, which was broadcast on October 21, 2021. Many lessons have been learned from this disaster. By using the third tube of the Gubrist tunnel, now under construction, as an example, the FEDRO project managers explain recent developments concerning the safety of road tunnels.

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.

A1 OHRINGEN – OBERWINTERTHUR MEASURES TO OPTIMIZE TRAFFIC FLOW

During peak hours, the motorway section between Winterthur Ohringen and Oberwinterthur is highly congested. To ensure a stable flow of traffic, as well as to minimise potential backlog at the junctions, measures are being taken by the Federal Roads Office to improve and optimise the traffic situation. In addition, constructional adjustments are being made and traffic signal systems are being installed at the junctions.

Section 48 on the national motorway A1 between Winterthur Ohringen and Oberwinterthur ranks among the most congested motorway sections in Switzerland. Stretching 4.3 kilometers, it is jammed during peak hours on a nearly-daily basis. This bears negative consequences for the road networks of the Winterthur city agglomeration. The implementation of measures to optimise traffic flow is due to alleviate congestion during peak hours on both the motorway and secondary road networks, as well as to minimise the risk of accidents. Amongst other things, these measures include extensions of the Oberwinterthur motorway junction and the acceleration lane at Forrenberg service station, the widening of existing emergency bays and the installation of a total of 19 signalling portals. The total costs of the project amount to 29 million Swiss francs. In order to prevent traffic backlog at the junctions, constructional adjustments are undertaken and new traffic signal systems are being installed at the junctions Winterthur Ohringen and Oberwinterthur.

The scheduled measures serve as an interim solution until the 6-lane extension between Winterthur Töss and the intersection Winterthur Ost will be commissioned. Current plans call for the motorway extension to be implemented between 2035 and 2040. Holding mandates as project-owner support unit and construction supervisor, R+R has been providing assistance to the general project management team of the Federal Roads Office since early project stages. In this capacity, R+R supports and advises the general project management team in project management, project controlling and in other selected issues.
