Welcome Maria Jose Hernandez Guevara
We are delighted to welcome Maria as a new member of the R+R staff and wish her every success in her new role.
Maria holds an MSc in Civil Engineering (Geotechnical Engineering/Construction and Maintenance Management) from ETH Zurich, as well as a BSc in Civil Engineering (Honours, cum laude) from the Universidad de Los Andes in Bogotá, Colombia.
Thanks to her many years’ experience in client representation, tunneling and underground construction, procurement, and operational and strategic project management, she is an excellent addition to our R+R-Team’s consultancy and technical expertise.
N11/60, N01/42 UPlaNS – ZH-Ost–Kloten Süd Interchange (ZOK), Completion of the Maintenance Concept (EK) Phase
Renato Käppeli / Stefan Isler
Over the past two years, we have supported the Federal Roads Office (FEDRO) as project-owner support unit in the development of the maintenance concept (EK) for the ZOK project.
In addition to renewal work, smaller, targeted improvements to enhance traffic safety and traffic flow were also examined.
A particular challenge in this demanding project was the dense population and high traffic volume in the vicinity of Zurich Airport.
Approval for the EK has been granted, and we look forward to supporting the next project phases.

N06.32 EP Muri – Rubigen
On April 23rd, 2026, the Federal Department of the Environment, Transport, Energy and Communications issued planning approval for the "N06.32 EP Muri – Rubigen" maintenance project on the A6 motorway to FEDRO’s Thun branch. If no objections are received, the next phase of the planning process can be started. Actual maintenance work on this section of the motorway as well as on the Worb feeder road will be carried out from 2029 onwards.
N08 EP Sarnen South – Hergiswil
On the northernmost section of the N8, which forms part of the important transit axis between Central Switzerland and the Bernese Oberland, extensive renovation work is planned for the coming years on the route, engineering structures, and operational and safety facilities. We are delighted to be supporting the Zofingen branch of ASTRA as the client's representative in this project.

FOLLO LINE BENCHMARKING
The new Follo Line, most of which runs through a tunnel, links Oslo to Ski and will become the main axis for south-eastern Norway’s rail traffic in the future. On behalf of Jernbaneverket, the infrastructure operator, R+R reviewed the project costs and correlated them with comparable international projects as part of a benchmarking study.
The existing main railway line from Oslo towards the south-east is heavily used and is relatively slow on account of its routing. In order to improve the situation, the construction of a new 25-km line (most of which passes through a tunnel) directly connecting the cities of Oslo and Ski has been incorporated into the National Transport Plan for 2010-2019. The project is complemented by structural expansion work near the Oslo and Ski junctions. A start was made on the planning work for the Follo Line Project in 2010. Once it is completed, the Follo Line will serve as the new main axis for rail traffic between Oslo and the region to the east of the Oslo Fjord, as well as for long-haul and international traffic to Sweden. The project will create an additional fast and efficient axis for traffic in this corridor where usage is already heavy, thereby meeting one of the fundamental requirements for an attractive offering of transport services.
On behalf of the client, the Norwegian railway network operator Jernbaneverket, R+R carried out a cost benchmarking exercise on the available cost estimates. The first step was to analyse the cost structures in detail. Based on the extensive technical documentation, key costings were determined. The work focused on a comparison of the key costings for the Follo Line with the corresponding figures from the extensive project database assembled by R+R under the auspices of the Infracost project, based on cost data for over 200 international rail projects in the last 20 years. It is evident that the construction costs for the Follo Line tunnel are somewhat less than the average for comparable projects, whereas the costs of the earthworks and the technical rail equipment are above the average. The analysis singles out those areas with above-average costs, identifies the cost drivers and provides Jernbaneverket with indications of possible savings potentials and suggestions for future measures to reduce costs.
