BIN <br /> Structural Analysis Report September 28, 2017 <br /> Carrier Site Number: SE52XC338 2 <br /> 1 Data Provided and Assumptions <br /> Data—Site walk photographs and a previous structural analysis by North West Tower Engineering dated <br /> 07/10/2010 were used to model and analyze the structure. <br /> Assumptions—The following assumptions were made in order to complete the analysis of the structure. All <br /> assumptions MUST be checked. If any assumption is found to be inaccurate Precision Design &Drafting shall be <br /> immediately notified so that the appropriate changes can be made to this report. <br /> Assumptions are as follows: <br /> 1. The existing monopole and its foundation were constructed as shown in the original design documents, <br /> photos, and/or other documents. <br /> 2. The existing monopole and its foundation are in good condition with no corrosion,damage or fatiguing <br /> which could cause a reduced capacity in any member. <br /> 3. The existing monopole meets the current code design loads and parameters. <br /> 4. The existing antenna mounts are in good condition with no corrosion, damage or fatiguing which could <br /> cause a reduced capacity in any member. <br /> 2 conclusions <br /> New Antenna Mounting Pipe: Three new panel antennas will replace the five existing panel antennas on new <br /> antenna mounting pipes which attach to existing standoff arms, attached to an existing ring mount on the <br /> monopole. The attached analysis shows that the new antenna mounting pipe is capable of supporting the design <br /> loads and was found to be structurally adequate. <br /> Existing Monopole: A previous structural analysis North West Tower Engineering dated 07/10/2010 states a <br /> tower rating of 65.9%. The attached analysis shows that the proposed configuration will increase the tower rating <br /> by approximately 7.81%. Therefore, the existing monopole is capable of supporting the design loads and was <br /> found to be structurally adequate. <br /> New Cabinet H-Frame: One new Telco and one new PPC cabinet will be added on a new cabinet H-frame on a <br /> new concrete slab at ground level. The attached analysis shows that the new cabinet H-frame and associated <br /> attachments are capable of supporting the design loads and were found to be structurally adequate. <br /> New Cabinet Anchorages: One ECAB cabinet and one new BCAB cabinet will replace an existing cabinet on a <br /> new concrete slab at ground level. The attached analysis shows that the new cabinet anchorages are capable of <br /> supporting the design loads and were found to be structurally adequate. <br /> 11768 Atwood Rd,Suite 20,Auburn, CA 95603 Tel: (530)823-6546 bret@pdnd corn <br />
