The structure is a 3 sheet fort of King sized members.
Wall fasteners are of 1 1/4″ roofing nails with green yarn and used shoe laces. Internal fasteners are of small and medium sized binder clips with center column of 1/2″ PVC pipe and #10 can filled with pennies footing. The electrical system is of a single 110v receptacle powering lighting and a computer for viewing of Waterboy and appears to be sufficient. Evidence of movement within the structure was significant as is typical of structure of this type. Flexibility in design appears to meet earthquake design requirements as well as class W (wood) soils design requirements. This fort meets 2 day Birthday design requirements. Evidence of need for repair was not observed.
