Dish Wireless SESEA00377C Everett City Hall — 21015.312 September 27, 2023 <br />Structural Analysis Report Page 3 <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 Dish Wireless <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 Dish Wireless 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 will be mounted to the parapet of an existing building rooftop with an overall height <br />of 133'. The equipment shall be anchored to a new steel platform. <br />The Client provided us with original building drawings dated 1979. Photos of the site and architectural <br />plans were also provided for the proposed revisions. All geometry, member sizes, and material <br />strengths used in our analysis were based on this information. If anything differs from the information <br />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 <br />Proposed Appurtenance <br />Sector <br />Mount Type <br />Configuration <br />Configuration (Bold=New) <br />(2) Commscope Panel Antennas <br />Model No. FFW-65B-R2 <br />Mount antennas to new wall mount and <br />A <br />None <br />(2) RF4450t-71A <br />mount appurtenances to new Unistrut at <br />(2) RF4451d-70A <br />existing building parapet <br />(1) OVP <br />(2) Commscope Panel Antennas <br />Model No. FFW-65B-R2 <br />Mount antennas to new wall mount and <br />B <br />None <br />(2) RF4450t-71A <br />mount appurtenances to new Unistrut at <br />(2) RF4451d-70A <br />existing building parapet <br />(1) OVP <br />(2) Commscope Panel Antennas <br />Model No. FFW-65B-R2 <br />Mount antennas to new wall mount and <br />G <br />None <br />(2) RF4450t-71A <br />mount appurtenances to new Unistrut at <br />(2) RF4451d-70A <br />existing building parapet <br />(1) ovP <br />The coax cables that serve the antennas weigh less than 5 Ib/ft and are therefore exempt from the <br />requirements of Chapter 13 of ASCE 7. <br />EQUIPMENT CONFIGURATION <br />All loading for the rooftop equipment was provided to us from the client. The client is proposing the <br />following modifications at the equipment cabinets: add (1) steel platform, add (1) H-Frame, add (1) <br />equipment cabinet, add (1) power protective cabinet, add (1) safety switch, add (1) submeter, add (1) <br />fiber NID enclosure, add (1) fiber telco enclosure, and add (1) GPS unit. <br />250 4th Avenue South, Suite 200 <br />Edmonds, WA 98020 <br />ENGINEERING ph.425.778.8500 1 f.425.778.5536 <br />www.cgengineering.com <br />
