Sabre Towers&Poles <br /> Job Number:54682 <br /> January 26,2012 <br /> Introduction <br /> The purpose of this analysis is to determine if the existing tower is in <br /> conformance with the requirements of ANSI/TIA-222-G, while supporting <br /> specified equipment. The tower is a 80' monopole and was originally <br /> manufactured by Sabre Towers & Poles (#30430). The tower has not yet been <br /> erected. The analysis is being performed for Clearwire Corporation, <br /> Rosemont, IL. <br /> Method of Analysis' <br /> The computer program that was used for this analysis is described on the <br /> attached page. The analysis was performed using a basic wind speed of 90 <br /> with no ice and 50 with 0.75" ice, in accordance with ANSI/TIA-222-G. <br /> Factored resistances and load factors were also determined in accordance with <br /> this standard. <br /> Supported Equipment <br /> See page Al of the "Plots and Calculations" section of this report for equipment <br /> loading. The lights were assumed to be fed by two (2) 1-5/8" lines (or <br /> equivalent) and the future carrier was assumed to be fed by twelve (12) 1- <br /> 5/8" lines. <br /> The transmission lines are assumed to run inside the pole. <br /> Results <br /> The results of the analysis show no overloads in any portion of the monopole <br /> shaft or the existing anchor bolts (per Valmont design dated 8/2/10). <br /> See conclusions below for modifications required to accommodate existing <br /> foundation and loading. <br /> 1 <br />
