IMEG’s San Francisco structural team (formerly Nishkian Menninger) provided structural design services for the addition of a one-story concrete shear wall building designed with provisions for the future addition of five more levels. The floor system is pan-joist with reinforced concrete columns. Installation of a new Phillips’ MRI scanner on the existing ground floor level, new mechanical units on the third-floor roof, and duct penetrations at the second floor completed the project.
