SEA DT Everett—20048.208 February 27,2020 <br /> Structural Analysis Report Page 2 <br /> INTRODUCTION <br /> CG Engineering was retained by New Wave Architecture (Client)to provide structural analysis of the <br /> existing 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, a structural <br /> analysis for a previous modification dated 7/29/2008,and structural calculations performed by CG <br /> Engineering for a previous modification dated 11/15/2017.The client also provided us with structural <br /> drawings dated 02/02/1981. Architectural plans were also provided for the proposed revisions. All <br /> geometry, member sizes,and material strengths used in our analysis were based on this information. If <br /> anything differs from the information contained in these documents, CG Engineering should be notified <br /> 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 <br /> (1)Amphenol Antennas Model No.#BXA-80063-8CF-3 <br /> Model No.#BXA-80063-8CF-3 (2)Amphenol Antennas <br /> (1)Amphenol Antennas Model No.#HEX458CW0000G <br /> Model No.#QUAD458C0000G (1)Ericsson RRU32 B66 <br /> D1 (2)Amphenol Antennas (1)Ericsson RRUS32 B2 Exist antenna <br /> Model No.#HEX458CW0000G (1)Ericsson Antennas frame <br /> (1)Ericsson RRU32 B66 Model 4408 with 6514 <br /> (1)Ericsson RRUS32 B2 (1)Ericsson 4449 <br /> (2)Twin diplexers (1)OVP 12 <br /> (1)Amphenol Antennas (1)Amphenol Antennas <br /> Model No.#BXA-80063-8CF-3 Model No.#BXA 80063 8CF 3 <br /> (1)Amphenol Antennas (2)Amphenol Antennas <br /> Model No.#QUAD458C0000G Model No.#HEX458CW0000G <br /> (2)Amphenol Antennas (1)Ericsson RRU32 B66 Exist antenna <br /> D2 (1)Ericsson RRUS32 B2 <br /> Model No.#HEX458CW0000G frame <br /> (1)Ericsson RRU32 B66 (1)Ericsson Antennas <br /> Model 4408 with 6514 <br /> (1)Ericsson RRUS32 B2 (1)Ericsson 4449 <br /> (2)Twin diplexers <br /> (1)OVP 12 (1)OVP 12 <br /> 250 4th Avenue South,Suite 200 <br /> Edmonds,WA 98020 <br /> O ph.425.778.8500 f.425.778.5536 <br /> ENGINEERING www.cgengineering.com <br />
