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 A14 BUCHRAIN EXIT – RÜTIHOF JUNCTION

All sections of the Swiss motorway network need to be regularly maintained. Corrective maintenance measures for the A14 motorway section between Buchrain exit and Rütihof junction are scheduled to take place between 2021 and 2022. The roadway, as well as a number of associated structures, have either reached the end of their life span or no longer meet the necessary requirements. Along with the maintenance work, noise protection systems are to be refurbished and the access and exit lanes of the service station St. Katharina will be adjusted to meet current regulatory standards.

The objective of the motorway maintenance project is to ensure continuous and intervention- free operation for the next 15 to 20 years. Extensive pavement renewal work is required to meet this end, during which the wearing and binder courses will be fully renewed and partially strengthened. Additionally, the Foren overpass needs to be refurbished and road restraint systems as well as operation and security installations need to be updated to meet current requirements. Existing precautionary measures for the protection of local groundwater resources will also be reviewed. Another aspect concerns noise protection. In addition to the other measures, the installation of a low-noise pavement surface and sound-proof windows in adjacent buildings help to ensure compliance with current threshold values.

R+R supports and advises the project management team of the Federal Roads Office in project management and controlling tasks. In particular, this includes the development and establishment of project basics, procurement, technical support, controlling and public relations. Furthermore, R+R will provide construction site management during the subsequent construction phase.
