L.G Wood Pole SCIP ID#: 18934-012F Site Address: 1210 Mohawk Blvd Springfield, OR 97477 County: Lane County Jurisdiction: City of Springfield Project Description: Structural Analysis for a Wood Pole Replacementwith a maximum allowable height increase up to -34'-4" A.G.L. To Whom It May Concern: We were commissioned by AT&T to perform a structural analysis of the above referenced project for AT&T proposed antenna implementations. The intent of our analysis is to determine a wood pole replacement for the existing 29'-0" wood pole, No. 69133, located at 1210 Mohawk Blvd., Springfield, OR capable of supporting AT&T's proposed antenna implementations. Our structural analysis was performed based on the requirements set forth by the National Electrical Safety Code (NESC 2017). The maximum anticipated pole stress usage is expressed as a percentage of overall capacity as a result of the associated NESC Rule 250B Construction Grade C. For pole structural analysis, referto O -Calc Pro Analysis Report. It should be noted that the structural analysis is limited to computer assisted structural analysis and theorical capacity of the pole. If the pole is of lower material grade than the assumed material strength used in the analysis, additional capacity may not exist. As such, J5 Infrastructure Partners will be notified in which a revised structural analysis will be required. Proposed New -34'-4" AGL Pole Replacement: Length of Pole: 45 ft. Pole Class: 5 Min. Embedment: 10'-8" Wood Species (Fiber Strength): Douglas -Fir (8000 psi) Existing power lines: At 28'-2" (assumed for the purpose of this structural analysis) J5INPRASTRUCTURE PARTNERS 2030 Main Street, Suite 200,1.ne, CA 92614 (949) 247-7767 A@ querque, NM o Base, ID o EI Pew, T o Las Vegas, NV o Denver, CO o Irvine, CA Page 1 of 2 Stress Usage: Pole = 30% Due to limited data, J5 Infrastructure Partners made certain assumptions regarding our evaluation. The new pole replacement and embedment are presumed to be properly installed in accordance with all applicable codes. All mounted antenna mounts, and relevant equipment are presumed to be properly fastened and in good reliable structural condition throughout the lifetime of the pole. Should any structural elements be deemed to be altered, J5 infrastructure Partners shall not be held liable for any structural deficiencies. Based on ourfindings, the existing 29'-0"wood pole, No. 69133, located at 1210 Mohawk Blvd., Springfield, OR can be replaced with a new 45' -Class 5 wood pole w/ 10'-8" min. embedment as per ANSI or equivalent.
