Leading planning for leading medicine: BIM at the new Stuttgart Cancer Center

With the Stuttgart Cancer Centre – Eva Mayr-Stihl Tumor Center, the Klinikum Stuttgart is getting a new facility in which interdisciplinary efforts are being made to fight cancer. This new building was planned with BIM.

More than 10,000 cancer patients are treated at Stuttgart Hospital every year. In order to bring together the broad expertise in the various specialist areas surrounding cancer medicine on site under one roof in the future, the new Stuttgart Cancer Center (SCC) - Eva Mayr-Stihl Tumor Center is currently being built in the heart of Stuttgart. After its completion (expected in 2024), an oncology day clinic, nuclear medicine, radiation therapy and other areas of cancer patient care will work hand in hand here. Schmidt Plöcker Architekten from Frankfurt am Main were responsible for the execution and planning of this special healthcare building, while the design planning was the work of Sweco. On behalf of the general contractor, Gustav Epple GmbH, this was to be carried out using the BIM method - OPEN BIM to be precise.

As part of the master plan for the new Campus Klinikum Stuttgart, the new building closes the urban edge at the corner of Kriegsbergstraße/Hegelplatz. Between the second basement and second floor, the brachytherapy and cancer therapy areas as well as oncology day care will be housed. The floors above will house - with another 50 beds - the care and functional areas of radiation and nuclear medicine. Structurally, the building is a reinforced concrete construction with flat ceilings. Some ceilings and walls are made of baryte concrete due to the radiation protection requirements of the design.

In addition to the pure BIM-based design, the architects also took over the overall BIM coordination, the preparation of the client information requirements (CIR) and the BIM execution plan (BEP), as well as the coordination of a model-based digital attribute database for integrating the component information of all specialist consultancies. The building model was created in ALLPLAN. From this, it was possible to derive all the necessary plans, such as floor plans (ground plan and floor levels) and ceiling levels, or detailed plans (wall views in the form of sectional derivations). Derivations from the model were also used for detailed planning.

The BIM coordination of the project was carried out using the open BIM platform Bimplus. The cloud-based solution was used to connect the external specialist consultancies and their models and to interface with the Prevera database, which was used to generate an integrated technical room book for the transfer of room, door and window information. The exchange of attributes between architectural and technical models or the different programs also ran bidirectionally via the BIM platform. In addition, Schmidt Plöcker used Bimplus for quality assurance and verification of the model as well as for documentation to historize through revision of the various specialist models. Communication among the project participants took place via the integrated Issue Manager. For further quality assurance of the BIM models, the review software Solibri was used, among others.
