Infrastructure consulting

Drees & Sommer Switzerland supports public and private clients in the initiation, planning, and realization of infrastructure projects. Public interest is usually particularly high in this area. Therefore we work with our clients to clarify the requirements and objectives before the project begins. This means we can set the course for the success of the project at an early stage.


There is a huge backlog in maintenance for the Swiss railway network. A steady expansion of the railway infrastructure combined with ever longer and heavier trains has led to an increasing load on the system components in recent years and, as a result, also to an increasing need for maintenance. The necessary projects and measures often have to be carried out during ongoing railway operations and in coordination with major projects. The complexity of maintenance is constantly increasing under these circumstances. More

Urban sprawl and population growth in Switzerland continue to increase. This increases the need for additional mobility options. Railways are continuing to gain in importance compared to road transport. This applies to both passenger and freight transport, which must be shifted from road to railway. This is the only way to achieve the internationally agreed climate targets. The capacity of the railway infrastructure must be significantly increased in several expansion stages by 2035. This will require massive investment in expansion projects. More


Numerous expansion projects and more frequent services in recent years have led to the Swiss timetable becoming increasingly dense in both local and long-distance transport. The increase in freight traffic as a reaction to the policy of shifting freight from road to rail has exacerbated this. At the same time, new construction projects are putting a strain on scheduling and interfering with customers’ journey times. Comprehensive planning of construction projects at the interface between construction and operation is therefore becoming increasingly important. More




We use our expertise in project management to support public and private clients in the initiation, planning, and realization of rail projects. We either act in a supporting role as project managers or assume overall responsibility as client-side project managers.

We ensure that your railway projects run smoothly with integrated and consistent construction scheduling. As part of capacity planning, we ensure the route view of the construction measures as portfolio management. We develop the construction phase planning for the execution, taking into account railway operational and constructional aspects, and create a detailed interval/closure plan. If required, we also take care of the proper awarding and invoicing of services as well as the overall cost management.

This means we can support:
