Page | 5 3.3) Liability Waiver and Limitations Our structural calculations are completed assuming all information provided to Ladera Engineering Group is accurate and applicable to this site. For the purposes of calculations, we assume an overall structure condition as erected and all members and connections to be free of corrosion and/or structural defects. The structure owner and/or contractor shall verify the structure’s condition prior to installation of any proposed equipment. If actual conditions differ from those described in this report, Ladera Engineering Group should be notified immediately to assess the impact on the results of this report. Our evaluation is completed using industry standard methods and procedures. The structural results, conclusions and recommendations contained in this report are proprietary and should not be used by others as their own. Ladera Engineering Group is not responsible for decisions made by others that are or are not based on the stated assumptions and conclusions in this r eport. This report is an evaluation of the mount structure only and does not determine the adequacy of the supporting structure, oth er carrier mounts or cable mounting attachments. The analysis of these elements is outside the scope of this analysis, are assumed to be adequate for the purpose of this report and to have been installed per their manufacturer requirements. This document is not for construction purposes. 4) ANALYSIS RESULTS Table 3 - Mount Component Stresses vs. Capacity (Pipe Mount, Critical Sector) Notes Component Critical Member Centerline (ft) % Capacity Pass / Fail 1,2 Mount Pipe MP1 96.0 6.0 Pass Structure Rating (max from all components) = 6.0% Notes: 1) See additional documentation in "Appendix C - Software Analysis Output" for calculations supporting the % capacity consumed. 2) See additional documentation in “Appendix D – Additional Calculations” for detailed mount connection calculations. 4.1) Recommendations The mount has sufficient capacity to carry the proposed loading configuration. In order for the results of the analysis to be considered valid, the following must be completed. 1. All bolts and hardware should be checked for tightness and condition prior to installing the proposed equipment. 2. Pursuant to ATT-CEM-24002, the proposed Ericsson AIR equipment in position 2 [from front of mount looking towards building] requires a minimum mount pipe diameter of 2.875” OD. The pipe in this position, per sector, shall be (1) 2.5 STD Pipe x 8’ long (CEQ# ANT.16008 or approved equal) with existing hardware. No structural modifications are required at this time, provided that the above-listed changes are implemented.
