Abstract : The purpose of the report is to document immediate and potential applications of the spiral generation construction process to Military Construction. Costs are shown for buildings constructed by fabricating shell structures in a spiral fashion using factory processed rigid plastic foam board, and costs are shown for Military Construction. An economic study based on such costs indicates that it is not economical to use plastic foam board shells except in limited applications, such as a Cold Storage or Freezer Facility or large (100-ft) open span construction. There are potential savings of shipping weight, shipping volume and construction time, when comparing Foam-in-Place shell structures (an undeveloped process) to prefabricated metal buildings. These potential savings are important logistic considerations for emergency overseas construction. The following estimates represent potential savings of Foam-in-Place construction of shell structures as a percentage of prefabricated metal buildings: cost 15-70%; shipping weight 50-65%; shipping volume 60-75%; erection time, manhours 55-85%. The actual savings will vary with the specific application.
