This discussion has been rooted in observation and experience in the design and construction environment. It has attempted to generalize the issues sufficiently to allow simple estimates to be made that subjectively quantify the value of improved seismic monitoring. The total annualized savings described above amount to more than $140 million per year after implementation of the ANSS (summarized, together with identification of the benefit recipients, in Table 6.1). These calculations were also performed for the situation where 3,000 buildings nationwide are instrumented, rather than the approximately 600 planned as part of the existing ANSS proposal. These calculations indicate that such an expanded instrumentation program would provide potential annualized savings of about $250 million.
