Camden-Clark Memorial Hospital has been serving the Mid-Ohio Valley of West Virginia and Southeast Ohio community since 1898. The South Tower Addition solidifies the hospital’s presence while meeting their expanding services. The 4-story, steel-braced framed structure provides 174,000 square feet of additional space to the Hospital, including 11 operating rooms, an 18-bed recovery area, 18 private patient rooms, a cafeteria, a new entrance lobby, and more. In addition, the structure was designed to support four future floors. One of the project’s primary challenges was constructing it over and around a portion of the existing hospital, without disrupting services. The existing operating rooms were located in a one-story structure with a concrete joist roof above. Since this roof was to become a floor in the new addition, it needed to be strengthened with a reinforced bonded topping slab. However, shoring of the existing roof was not permitted in the operating rooms below. A calibrated hanger system with drilled anchors was designed to temporarily support the slab from above during construction.
