Swiss Federal Railways is investing in efficient and climate-friendly public rail transport facilities at Zurich Stadelhofen station.  The first phase of the project is now in its final  stages thanks to technical support provided by Drees & Sommer as project controller and consultant.

The Swiss Federal Railways (SBB) rail infrastructure development program  will see a significant increase in the capacity of Zurich Stadelhofen station by 2035. The necessary construction work is highly complex, particularly with regard to technical feasibility and the construction process, as work has to be undertaken in the city without interrupting rail operations. Essentially, the project involves the expansion of the station, the remodeling of existing facilities and the construction of new tunnel sections.

Drees & Sommer rail infrastructure experts undertook a comprehensive analysis of the project during the pre-project phase. Based on their findings, the team introduced a project handbook and established a mandatory document filing structure. These basic tools were supplemented by a clear project structure plan and a project management schedule combined with  strict document management. Drees & Sommer established regular project control meetings and training on key PM topics. This helped the many project participants maintain and comply with the developed standards and  specifications. The team also supported the principal’s representatives at key meetings.

The entire project is based on SBB’s sustainability strategy and is in keeping with the principle of ecologically and socially sustainable development of both the economy and society. A resilient future-proof railway infrastructure not only protects the climate, but also benefits the towns and cities it connects.

More stringent safety standards and barrier-free design of the station are also stated objectives of the project. Synergy effects will make many construction processes cheaper and more efficient. Sustainable consumption and production concepts are firmly anchored in the strategy for the planned sales areas in the station.

By establishing basic organizational structures and providing intensive and proactive scheduling support for the principal, Drees & Sommer succeeded in meeting all deadlines and establishing high quality standards. As a result, the SSB project is ideally positioned for the actual execution phase.
