40 <br />E71 <br />Wind and Wind -Related Considerations: <br />Wind hazard types taken into consideration during site inspection include lay -down hazards, roll-over <br />hazards and debris hazards. Hazards in the form of 5 portable classrooms, unsecured metal bleachers and <br />wooden picnic tables were noted on the north side of the structure. Unsecured playground equipment was <br />evident on die south and east portion of the campus. Souther exposure is comprised of heavily wooded <br />fiat topography with a large open held and retention pond between facility and residential area. Northern <br />and western exposure is mostly residential and flat as well being heavily wooded. The eastern exposure <br />is flat and heavily wooded. 'There is limited exposure to large and small wind-borne debris within 300 feet <br />of the facility. The building was designed in 1984 and has no obvious wind design flaws with the exception <br />of lightweight metal open walkways between structures. <br />Building Characteristics:. <br />A partial set of structural and architectural plans for this facility was provided for evaluation. A clearly <br />defined continuous load path from foundation to roof is present. Upon site inspection and review of <br />structural plans it was evident brat the buildings' exterior walls are constructed of fully reinforced masonry <br />and have no sofispot areas. The plans called for an 8" CMU with a 4" brick veneer wall construction. 5" <br />pipe columns (standard weight) were employed extending from the concrete, steel reinforced footers to <br />top of walls. 36" steel truss girders (48" c/c) are attached to bearing points with two 114" full development <br />fillet welds. The roof is flat with a 3' overhang and decked with standard corrugated metal decking, 4" <br />lightweight concrete, and a modified bitumen roof covering. Roof design load (dead load plus live load) <br />is calculated to be 52 lbs. per square foot. No evidence of ponding or degradation was present on the roof. <br />All drains were clear and free of debris. <br />Windows, of an unknown glass type, comprised less than 7% of total exterior wall space. No <br />shuttering/protective system was in place for either windows or exterior doors. <br />The stringency ranking of the model building code used during the year of the buildings design (198 1) <br />according to the State of Florida Hurricane Shelter Evaluation Guidelines is a 2 on a scale of 0-4, the <br />most stringent being 4. <br />The building was in good condition with no visible signs of damage. <br />Life Safety/Emcrgency Power: <br />At the time of survey, the building conformed to fire codes. There was an emergency power supply <br />generator on site which powers exit lights, freezers and emergency lighting. <br />Conclusions: <br />When analyzed using the criteria outlined in [lie ARC 4496 [.cast -Risk Decision Making Guideline <br />Compliance Summary, Pelican island Elementary School was found to have characteristics which fall <br />
