IIPP 1 <br /> The lowest level of the escape has 2x12 joists and 6x8 beams which should be capable of <br /> supporting a 100 psf live load. <br /> My analysis has shown that when the members are in good condition,the escapes are <br /> substantially capable of supporting a 100 psf live load. However, there are some <br /> recommendations for repairs that I would like to see made. <br /> 1) The steel grating is currently painted, but the paint is peeling. It is important to keep the <br /> paint in good condition to deter corrosion. <br /> 2) Where the ladders bolt to the landings, there are several irtstances of corrosion at the bolt <br /> holes. This is likely due to the"flat"spot in ladder. The corrosion should be repaired by <br /> cutting the corroded area away and replacing with new steel welded in place. <br /> 3) Approximately 50°A of the round cross-bars that keep the bar grate from buckling are <br /> severely deteriorated. I recommend field welding a piece of 1"flat stock on top of the <br /> grating in locations where the cross bracing is less than 50%of original size. <br /> 4) An x-ray or ground penetrating radar should be used to verify that the knee brace anchors <br /> are indeed embedded into the concrete wall. <br /> Please let me know if there are any questions. <br /> Sincerely. <br /> Matthew Zawlocki, PE,SE <br /> , <br /> 4*/01,AL 7 S11‘" 57 <br /> (1d/i) <br />
