AT&T SN17 Edmonds—23007.128 February 9,2023 <br /> Structural Analysis Report Page 2 of 4 <br /> INTRODUCTION <br /> CG Engineering was retained by Ryka Consulting to provide structural analysis of the existing rooftop <br /> structure for the site modifications proposed by AT&T. <br /> The structural analysis completed by CG Engineering was inclusive of the structural elements that were <br /> affected by the addition of equipment and antennas associated with the proposed AT&T site <br /> modifications. Where applicable,this includes the antenna and equipment support structure and <br /> affected portions of the existing main structure. <br /> SITE DESCRIPTION <br /> This site consists of(3)sectors of antennas mounted to (5)steel rooftop skid mounts.The skid mounts <br /> are mounted to the roof of an existing two-story building with an overall roof height of 29'-11". <br /> The Client provided us with architectural drawings for the proposed site modification dated 1/23/23,as <br /> well as structural drawings for the original mount installation dated 05/07/18. Photos of the site and <br /> architectural plans were also provided for the proposed revisions. All geometry, member sizes, and <br /> material strengths used in our analysis were based on this information. If anything differs from the <br /> information contained in these documents, CG Engineering should be notified to revise our analysis. <br /> APPURTENANCE CONFIGURATION <br /> The structure was analyzed using the appurtenance configuration specified in the following table. All <br /> loading was provided to us from the Client. This table includes all known existing and future antennas <br /> for this site. <br /> Existing Appurtenance Proposed Appurtenance Configuration Mount Type <br /> Sector Configuration (Bold=New) yp <br /> (1)Kathrein Panel Antenna (1)Nokia AEQK Radio Antenna <br /> Model No.80010991 <br /> (1)Kathrein Panel Antenna (1)Cellmax Panel Antenna <br /> Model No.8001865 Model No.CMA-UBTMLBMLBHH-6516-16-12 <br /> (1)Kathrein Panel Antenna (1)Kathrein Panel Antennas <br /> Model No.80010764 Model No.80010991 Rooftop skid <br /> A (1)RRH 4T4R B12/14 320W AHLBA (1)DC6-48-60-18 frame <br /> (1)B66A RRH4x45-4R (1)RRH 4T4R B5 160W AHCA <br /> (1)RRH4x25 WCS 4R (1)RRH 4T4R B12/14 320W AHLBA <br /> (1)B25 RRH4x30-4R (1)B66A RRH4x45-4R <br /> (1)TT19-08BP111-001 TMA (1)RRH4x25 WCS 4R <br /> (2)DC2-48-60-0-9E (1)B25 RRH4x30-4R <br /> (1)Kathrein Panel Antennas (1)Nokia AEQK Radio Antenna <br /> Model No.80010991 (1)Cellmax Panel Antenna <br /> (1)Kathrein Panel Antennas Model No.CMA-UBTMLBMLBHH-6516-16-12 <br /> Model No.8001865 <br /> (1)Kathrein Panel Antennas (1)Kathrein Panel Antennas <br /> Model No.742-264 Model No.80010991 Rooftop skid <br /> B (1)RRH 4T4R B12/14 320W AHLBA (1)DC6 48 60-18 frame <br /> (1)B66A RRH4x45-4R (1)RRH 4T4R B5 160W AHCA <br /> (1)RRH4x25 WCS 4R (1)RRH 4T4R B12/14 320W AHLBA <br /> (1)825 RRH4x30-4R (1)B66A RRH4x45-4R <br /> (2)LGP21401 TMA (1)RRH4x25-WCS-4R <br /> (2)DC2 48 60 0 9E (1)B25 RRH4x30-4R <br /> Table continued on following page... <br /> C � 250 4th Avenue South,Suite 200 <br /> Edmonds,WA 98020 <br /> ENGINEERING ph.425.778.8500 I f.425.778.5536 <br /> www.cgengineering.com <br />
