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.

N1, Extension of the Zurich Northern Bypass

On September 22nd, 2020, the third tube of the Gubrist motorway tunnel was broken through after 1,000 days of construction work and an excavation length of about 3,000m. Thus, an important milestone of the N1 Zurich Northern Bypass extension project was finally reached.

However, the work continues. Within the next two years, the construction of the roadway, the interior fittings and the installation of operating and safety equipment will follow. After completion of the third tube, three lanes will be provided for Bern-bound traffic. Commissioning and opening for regular traffic are expected to take place at the end of 2022.

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.
