The purpose of this study was to ascertain the feasibility of incorporating certain protective concepts into selected systems-constructed schools. These concepts were to be incorporated at a minimal cost increase, with minimal sacrifice of amenities, and with no detrimental effect on facility configuration. The environmental hazards taken into consideration were earthquakes, tornadoes, hurricanes, and noise. The five schools selected for analysis are currently in use. The design changes are offered as suggestions that might be incorporated into future designs in order to better protect the inhabitants of the facility. Photographs may reproduce poorly. (Author/MLF)
