Wetzikon Hospital reconstruction and extension, environmental building management (EBM)

The project

Place: Wetzikon (ZH)
Customer: Steiner AG (main contractor)
Phases: Implementation and commissioning
Period: 2018-2024
Construction costs: Approx. CHF 250,000,000


The Wetzikon hospital will be extended by several buildings between 2018 and 2024 while the existing buildings will be fully renovated. All construction will be performed while hospital operations are ongoing, which creates high demands for management, logistics, safety and executions. The Wetzikon municipality, the building approval authority, therefore required environmental building management (EBM) for the whole duration of the project.
