School Building Renovation, Seismic Retrofit, and Building Addition

IMEG provided structural engineering and design services for Bozeman School District No. 7’s high school building facility in southwest Montana. The project consists of the renovation of a 125,000-sf high school building facility and construction of a 50,000-sf new building expansion/addition for the Bozeman High School. The renovation portion of the project included a complete seismic retrofit of the existing building utilizing CMU shearwalls, brace frames, shotcrete shearwalls, helical piers, and a variety of inventive details. The new building addition utilized composite steel framing with brace and moment frames and wood frame construction. Our firm was involved with the design and construction team starting in the very early stages to determine what renovations were most feasible from both an economic standpoint and a constructability standpoint. Construction of this $30 million project was phased over a couple of years to allow portions of the buildings to remain open and in use by the school district. Our firm also served as the primary special inspection agency on the project to help ensure a high level of quality throughout the construction process.
