It is the carrier's responsibility to ensure compliance to the <br /> structural limitations of the existing and/or proposed antenna mounts. TEP did not perform a site <br /> visit to verify the size, condition or capacity of the antenna mounts and did not analyze antennas <br /> supporting mounts as part of this structural analysis report. <br /> 8) The following material grades were assumed: <br /> a) Legs:ASTM A53-B-46 <br /> b) Bracing:ASTM A36 <br /> This analysis may be affected if any assumptions are not valid or have been made in error. Tower <br /> Engineering Professionals should be notified to determine the effect on the structural integrity of the <br /> tower. <br /> tnxTower Report-version 6.1.4.1 <br />� -- - 1�. ---- � -�-- <br />
