June 2022 - Rebuilding the 1917 building from the inside out.
Workers are undertaking a month's long process of seismic reinforcement work on the historic 1917 building.
They are currently creating sheer walls that connect to new structural footings in the basement and will rise up three stories. This work will bring the school up to the latest seismic safety requirements and make staff and students safer.
To get the concrete into tight places within the historic building, workers use a method called shotcrete. It can be fed by hose into restricted spaces and it sprays the concrete into and over the structural steel framework. It’s a team effort and interesting to watch. Check out this video on OSM's Instagram.

What Is Modernization?
Benson's proposed modernization will completely reconfigure and update learning spaces with a focus on indoor environmental quality, sustainability and historic preservation. Full modernizations retain the historic character of the school while bringing those buildings up to code and concurrently creating a more modern learning environment. This is considered the most cost-effective, sustainable way to improve Benson, due to age, condition and historic significance.
