When applicable, Crown Castle has <br /> calculated and provided the effective area for panel antennas using approved methods following the <br /> intent of the TIA-222 Standard. <br /> 3.2) Assumptions <br /> 1) The tower and structures were maintained in accordance with the TIA-222 Standard. <br /> 2) The configuration of antennas, transmission cables, mounts and other appurtenances are as <br /> specified in Tables 1 and 2, and the referenced drawings. <br /> 3) The following material grades were assumed: <br /> a) Tower Legs:ASTM A53-1346 <br /> b) Tower Bracing:ASTM A36 <br /> c) Anchor Rods:ASTM A615-75 <br /> 4) TEP assumed the soil properties for the bottom layer of caisson from 40-ft to 42-ft to match the <br /> properties of the soil later. <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 /> 4) ANALYSIS RESULTS <br /> Table 4- Section Capacity(Summary) <br /> Section.
