In school construction, creating spaces that can serve multiple functions saves in longer term building expense. For Sherlock Elementary in Cicero, IL, the gymnasium needed to function as a storm shelter as a response to recently modified Illinois code requirements, ICC 500, that requires all education facilities to have at least one room in the building designated to protect occupants of the school and/or community in the instance of unprecedented weather conditions.

Looking at a rapid construction schedule, Wells was selected to provide a turnkey precast solution. Double Tees along the roof support the wide-open space needed for a gymnasium as well as the secure roof structured needed in a storm shelter requirement, while wall panels and hollowcore bring additional structural integrity and safety. Combined, these elements form a safe and secure boxed shape structure that resists high winds up to 250 mph, endures a fire rating of up to four hours, provides windowless panels for enhanced security, and most importantly withstands unprecedented environmental conditions, meeting the code requirements.
