Characterized by the structure of the Seventies the operation department of the Clinical Center Augsburg was showing significant lacks in hygiene and function compared with contemporary standards. Because of the flexible basic building structure and its current division into two mirrored identical units it was possible to restore this department with the consideration of the ongoing work process of the hospital nearly without disruption. As part of the general redevelopment of the Clinical Center Augsburg until 2025 the first phase could be meanwhile completed (10 out of 18 operating theatres) and started running in September 2013. The second and last phase with further 8 theatres will be completed in spring 2015. The new layout of the rooms is now consistently based on work-flow and was only possible after a complete strip down of the existing structures and the following reconstruction. To lower the running costs it was necessary to renew the entire technical fit-out, especially the ventilation. Accompanied with the restructuring process the services for patients will be extended. For example two hybrid operating theatres for angiography and neuro -surgery are available as part of the most modern medical equipment. The additional medical imaging supports the possibility for minimally invasive interventions. The striking layout of the operation rooms with fully glazed wall surfaces in blue transposes contemporary hygienic requirements and creates a pleasant and modern work environment.
