SEA DT Everett—17015.270 November 15,2017 <br /> Structural Analysis Report Page 1 <br /> INTRODUCTION <br /> CG Engineering was retained by Camp&Associates(Client)to provide structural analysis of the existing <br /> structure for the site modifications proposed by Verizon. <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 Verizon 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 /> The appurtenances are mounted to an existing building rooftop with an overall height of 112'. The <br /> equipment is located inside the building. <br /> The Client provided us with architectural drawings for an antenna installation dated 2009,as well as a <br /> structural analysis for a previous modification dated 7/29/2008.The client also provided us with <br /> structural drawings dated 02/02/1981. Architectural plans were also provided for the proposed <br /> revisions.All geometry,member sizes,and material strengths used in our analysis were based on this <br /> information. If anything differs from the information contained in these documents,CG Engineering <br /> 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 <br /> Sector Mount Type,. <br /> Configuration :(Bold=New) <br /> (1)Amphenol Antennas (1)Amphenol Antennas <br /> Model No.#BXA-80063-8CF-3 Model No.#BXA-80063-8CF-3 <br /> (1)Amphenol Antennas (1)Amphenol Antennas <br /> Model No.#BXA-70040-6CF Model No.#QUAD458C0000G Mount <br /> (1)Amphenol Antennas (2)Amphenol Antennas <br /> antennas& <br /> A Model No.#BXA-171063-8CF Model No.#HEX458CW0000GRRUs to exist <br /> (1)Amphenol Antennas (1)Raycap RCMDC-1064 PF-48 frame <br /> Model No.#BXA-171040-8CF (2)JMA DBC-67-C-2SF <br /> (1)Raycap RCMDC-1064 PF-48 (1)Ericsson RRU32 866 <br /> (1)Ericsson RRU12 B4 (1)Ericsson RRUS32 82 <br /> (1)Amphenol Antennas (1)Amphenol Antennas <br /> Model No.#BXA-80080-8CF-4 Model No.#BXA-80080-8CF-4 <br /> (1)Amphenol Antennas (1)Amphenol Antennas <br /> Model No.#BXA-70040-6CF Model No.#QUAD458C0000G <br /> (1)Amphenol Antennas (2)Amphenol Antennas Mount <br /> B Model No.#BXA-171063-8CF Model No.#HEX458CW0000G antennas& <br /> RRUs to exist <br /> (1)Amphenol Antennas (1)Raycap RCMDC-1064 PF-48 frame <br /> Model No.#BXA-171040-8CF (2)JMA DBC-67-C-2SF j <br /> (1)Raycap RCMDC-1064 PF-48 (1)Ericsson RRU32 B66 <br /> (1)Ericsson RRU12 B4 (1)Ericsson RRUS32 82 <br /> G (1)Amphenol Antennas (1)Amphenol Antennas <br /> Model No.#BXA-80063-8CF-4 Model No.#BXA-80063-8CF-4 <br /> 250 4th Avenue South,Suite 200 <br /> C C Edmonds,WA 98020 <br /> ® <br /> ENGINEERING ph.425.778.8500 I f.425.778.5536 <br /> www.cgengineering.com <br />
