ASSEMBLY STEPS: Figure 104 illustrates the assembly process for homeowners. As mentioned previously, in spring of 2009, a two-phase testing program was developed to comply with FEMA and NFIP legislation. The first phase included the required components to provide static elevation to the BFE in compliance with FEMA and the NFIP regulations. It did not include components beyond what were required for static elevation to BFE (fig. 105).152
The second phase added the ‘amphibious’ components, including the addition of the buoyancy blocks, the telescopic guidance posts and modification of utility connections to accommodate the rising and falling of the structure. These are elements that are not necessary for static elevation but allow the house to behave amphibiously (fig. 106). Because of the recent change in FEMA’s interpretation, which is that occasional flotation may now be deemed compliant with the NFIP, separation into the two phases will no longer be required.153
