    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.
