Part of the construction of the new Mineola Primary School on NE Loop 564 that has recently become visible is the gymnasium which will also double as a storm shelter.

Architect Perry Thompson explains the shelter materials and design are slightly different than the remainder of the facility which consists of standard construction materials commonly used in schools such as metal studs, burnished block wall and brick. 

The gym and shelter is 4,523 square feet which has been designed to allow the occupancy of 806 individuals. It has been designed to meet the 2031 high-growth scenario as provided in the 2021-22 demographic study commissioned by the district.

It meets the 2014 ICC 500/NSSA Standard for the Design and Construction of Storm Shelters.

Also to be included in the shelter:

* Critical support systems within the shelter that meet the wind and pressure missile impact requirements. 

* Adequate mechanical ventilation, toilet and hand-washing facilities 

* Adequate emergency lighting for all occupied shelter areas, occupant support areas, required corridors, passageways and means of egress.

* A first aid kit.

Specific materials and construction methods for the storm shelter are being utilized to meet the strict requirements of the code.

For example, insulated concrete forms are being used to hold the concrete in place during the concrete curing process. These forms are known in the construction industry as ICF.

They are made from foam similar in size and shape to that of a concrete masonry unit (CMU). They are hollow, but they contain plastic supports to accept and hold the steel reinforcing in place. Once the forms and steel reinforcing have been set, the forms are filled with a concrete and pea gravel slurry.

After the completion of the wall system, several open web steel bar joists will be embedded into the ICF wall frames. The open web steel joists support a metal deck and concrete roof to complete the envelope of the shelter.
