Project Description: Phase 1 of this project included the addition of a new vault, control and electrical room. During the design phase it was determined the vault would be constructed above a portion of a cavern. Foundations were designed to support the new vault. We took advantage of adding this vault to the adjacent linear accelerator vault to allow for sharing the primary beam barrier and saving the client additional construction costs. Additional support spaces received finish upgrades and enhanced the overall aesthetics of the department. The addition tied in well to the existing Medical Office Building and the masonry was a great match.
