Refer to the attached topographic profiles used to determine the topographic factor. <br /> 2. Parameters based on the 2015 International Building Code(IBC)and referenced standards. <br /> APPURTENANCE MOUNT/MAIN STRUCTURE ANALYSIS RESULTS <br /> Individual appurtenance mounts have been determined to be sufficient to support the proposed loads. <br /> Additionally,the existing structure has been determined to be sufficient to support the proposed <br /> appurtenance configuration. <br /> CONCLUSIONS/RECOMMENDATIONS <br /> We have determined that no upgrades to the existing structure are required for the proposed Verizon <br /> installation as described above in the appurtenance configuration tables. <br /> • Appurtenance Anchorage: <br /> The antennas and RRU's shall mount to the existing mounting pipes(2" std pipe min) on the <br /> existing antenna frames. Attach the antennas and RRU's to the pipe mounts with the mounting <br /> hardware provided by the manufacturer and in accordance with their installation instructions. <br /> CONDITIONS OF ANALYSIS <br /> This structural analysis is based on the documentation that was available to us. CG Engineering did not <br /> perform an observation of this site to verify the accuracy of the provided structure and appurtenance <br /> data, and we should be contacted immediately if there are any discrepancies with the information <br /> stated within this report. <br /> Our analysis is based on the assumption that the original structural design and all subsequent structural <br /> analyses were properly designed and permitted per the applicable building codes, and that the structure <br /> has been properly installed and is maintained to the minimum standards required by code. We assume <br /> the structure has no known deterioration or damage that would adversely affect its capacity. <br /> 250 4th Avenue South,Suite 200 <br /> o Edmonds,WA 98020 <br /> ph.425.778.8500 l f.425.778.5536 <br /> ENGINEERING www.cgengineering.com <br />
