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.

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.

MOTORWAY MAINTENANCE PROJECT LIMMATTAL INTERCHANGE – SCHLIEREN EXIT

The 30-year old Limmattal interchange – Schlieren exit section of the A1 motorway features six lanes and has a length of five kilometres. Within the framework of the Federal Roads Office‘s maintenance planning program, extensive refurbishment was undertaken in 2013 and 2014.

Operations within the corrective maintenance project encompassed the refurbishment of the pavement, adjustments to the guidance and protection systems, the provision of new cable conduit blocks, as well as corrective maintenance on structures and drainage systems. Various maintenance measures were carried out on pavement, bridge deck, shoulder curbs and sealings of the Limmat bridge, while expansion joints and bearings were replaced. Several under- and overpasses were refurbished as well. These construction measures allow for an additional 15 to 20 years of service, without any further intervention required.

A subsequent project phase will include the construction of a new road waste water-treatment plant close to the Oberengstringen service area. It is also planned to adapt the exit lane leading to the service area in order to comply with current technical standards, as well as to add electric cabinets.

R+R supported the project management team of the Federal Roads Office by providing comprehensive project management services. These included the procurement of multiple planning mandates and the submission of the construction works, project controlling of current contracts, cost monitoring and –planning as well as construction site management.
