4.8 Contents Seismic Damage Functions <br /> <br />The Technical Appendix contains facility-specific fragility data (cf. Tables 5-4a <br />and ,5-4b) for several types of contents and equipment at this facility. However, <br />most of the occupied portion of this building is "ordinary" office space and the <br />building does not contain a high percentage of specialized equipment. Thus, for <br />this analysis, we accept the typical or "default" assumption built into the FEMA <br />Full Data Module for Benefit-Cost Analysis of Seismic Mitigation Projects. That <br />is, that the contents percentage damage is equal to the building percentage <br />damage at each level of ground shaking (PGA bins in the Full Data Module). <br /> <br /> 4.9 Displacement Costs and Times <br /> <br /> For ordinary residential, commercial, or public buildings, displacement means <br /> that damage to buildings is severe enough so that occupants are displaced to <br /> temporary quarters while repairs are made. Displacement costs include monthly <br /> rental, other monthly costs, and one time costs such as round-trip moving costs. <br /> <br /> For this building, facility-specific displacement costs were estimated as <br /> documented in the Data Documentation Table (Table 3) above. Rental cost of <br /> temporary office space is estimated to be $0.92. This Iow value arises because <br /> the estimated rental cost of temporary office space is $2.00/sf, but somewhat <br /> less than half of the square footage is office space. The FEMA Full Data Module <br /> requires data entry as $/sf/month and thus the entered value of $0.92 takes into <br /> account actual rental rates and the proportion of the building which is office <br /> space. <br /> <br /> Other costs of displacement include replacement parking and other costs as <br /> summarized above in Table 3. <br /> <br /> Standard FEMA values (Full Data Module) for displacement times, which are <br /> proportional to estimated building damage percentages are used for Iow to <br /> moderate levels of damage. These values are a reasonable estimate of the time <br /> period necessary to complete repairs if the building were damaged in future <br /> earthquakes. However, for damage levels severe enough to require replacement <br /> of the entire building, we estimate that a minimum time to design and build a <br /> structure of this size and importance would be two years. <br /> <br /> 4.7 Economic Impacts of Loss of Function <br /> <br /> FEMA's What is a Benefit? Guidance contains a standard methodology to <br /> calculate the economic impact of loss of function of facilities providing public <br /> services. The base value of service is simply the cost of providing services (i.e., <br /> the annual operating budget). For the Eugene City Hall, there are several <br /> <br /> <br />
