This study examines the current use of manufactured relocatable (portable) classrooms in the public school districts of Florida to determine whether their use is a cost efficient and educationally effective and safe means of handling short-term accommodation needs. Areas of research include: economic impacts; the physical classroom environment; facility planning; construction methodology; and impacts on existing facilities. The study contains questionnaire data received from 57 school districts and 900 teachers; 23 relocatable site visits throughout Florida; manufacturing site visits; and results from meetings with principles, teachers, contractors, and industry representatives. The study concludes with answers to the questions posed in the RFA from the Florida Department of Education Office of Educational Facilities along with recommendations concerning the design and planning of future relocatable classroom facilities. Appendices provide sample questionnaires, the site visit survey, results of the teacher's questionnaire, and life cycle cost analysis. (GR)
