However, some structural deficiencies were noticed during the inspection. The items listed below require attention to assure full compliance: • Repair or replace any damaged existing opening protections. • Missing uplift connectors are considered a structural flaw and should be retrofitted. This can be accomplished by installing uplift connectors, or equivalent method (minimum capacity of 1000 lbs. each), at the top and bottom chords of each hip- girder truss to setback-girder at each truss connection. • Install remedial uplift connectors at the hip truss connections to the setback girders anywhere improper installation is noticed. Provide the missing fasteners at all other improperly installed connectors,particularly at the hip truss connections to the bottom chord bearing points. Other retrofits and/or documentation are required to comply with the criteria of a Type A hurricane shelter. • Complete all retrofits listed above required for Type B classification • Provide retrofits so that all openings (doors, windows, and louvers) meet ASTM E 1886 and ASTM E 1996 test standards for 115 mph design wind pressures and missile impact level C protection or better, or provide documentation of any existing openings that may be claimed to meet these performance requirements In addition to retrofits that must be made to Building E, architectural requirements must be considered as well. The Suinrnary of Recommended Criteria and Guidelines for Hurricane Shelter Classifications require that Type EHPA hurricane shelters have a restroom within the shelter area. Although the restrooms are contained within Building E, and themselves could be considered shelter areas, they are not accessible through interior openings of other designated shelter areas within the building 17-12 Hawaii County Multi-Hazard Mitigation Plan
