Non-structural retrofits include: • Install exterior mounted roll-down storm shutters for windborne debris protection of windows • provide seismic bracing of existing ceilings in essential facility areas , • removal of an incinerator stack that is a potential falling hazard,and • mitigation against hurricane and windstorms through protection against windborne debris impacts on rooftop mechanical systems and • anchorage of nearby ancillary structures on site that would otherwise be large debris sources.. This is a multi-hazard retrofit in which the State of Hawaii's contribution is • the retrofit of the ventilation system to mitigate against harmful volcanic gas emissions and • abatement of some indoor hazardous ceiling material. With these retrofits,the capability for continuity of operations during hurricanes and earthquakes is improved. Kau Hospital is the only hospital serving the southern part of the County of Hawaii;the nearest alternate hospital is over 60 miles away. The Hawaii County All-Hazards Assessment of Critical Facilities identified this 1968 facility as having a higher priority for hazard mitigation from a comprehensive risk analysis of 80 critical buildings in Hawaii County. $600,000 Cost(Design and Construction)are itemized as follows: Window Protection against Windborne Debris $287,000 Ancillary Structure Anchorage for Wind $5,000 Rooftop Equipment Protection against Windborne Debris $65,000 Incinerator Demolition to Remove Falling Hazard $80,000 Ceiling Seismic Bracing $163,000 The Benefit Cost Analysis Tool Version 4.5.5 indicates a 25-year Benefit of$4.001 M; Benefit Cost Ratio of 6.67 A19-1 Hawaii County Multi-Hazard Mitigation Plan
