Adena Cancer Center
Since their humble beginnings in 1895, the Adena Health System has remained focused on their commitment to providing the best medical care as they serve more than 650,000 people in 13 counties in South Central Ohio. In 2010, Adena Health System launched the construction of a new, freestanding cancer center. Located on their main campus, this multi-disciplinary cancer care center offers a wider spectrum of clinical and support services, from screening and diagnosis to treatment and counseling. When completed, the center will provide the kinds of services and technology usually found only in major metropolitan cancer centers.
The design of this new building includes many curved lines and a complex column grid system. Building Information Modeling (BIM) allowed for effective coordination between the different trades during design. The structural system includes steel joists on steel framing with steel braced frames and concrete shear walls. The building equipment includes two Linear Accelerators which are used on a daily basis. This required that multiple rooms are constructed as reinforced concrete vaults to prevent radiation leakage into the rest of the building. Rectangular rooms were designed with internal corridors or “mazes” with non-parallel concrete walls which helps reduce leakage of radiation at the doorways and the thickness of the concrete walls - typically 3’ 6” – and the roof were designed using criteria provided by the hospital’s physicist. The physicist calculated the minimum thicknesses for the roof and walls using an assumed 150 pounds per cubic foot density for the concrete. The contractor was required to verify this minimum density with testing.
