AT&T VVA6299 Part Gardner-17015.102 February 1,2017 <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 /> rooftop 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 /> The appurtenances are mounted within cylindrical FRP antenna shrouds on an existing building <br /> penthouse rooftop with an overall height of 110'-10". The equipment is anchored to a concrete floor <br /> slab inside of the building penthouse below the appurtenances. <br /> The Client provided us with architectural drawings for a previous antenna installation dated 01/21/2011, <br /> as well as structural calculations and architectural drawings for a different modification dated 4/11/2011 <br /> and 4/21/2011 respectively.CG Engineering also performed a structural analysis for a different <br /> modification dated 01/29/2016 with architectural drawings dated 01/29/2016. 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 <br /> Sector Configuration (Bold=New) Mount Type <br /> } (1) KMW Panel Antenna (1) KIV§W Panel Antenna <br /> Model No.EPBQ-654L8H8 Model No.EPBQx 654Y.8H8 <br /> (2)Kathrein Pane(Antennas (2)Kathrein Panel Antennas <br /> i <br /> Model No. %42-265 Model No.742-265 <br /> (2)TMAs (2)TMAs <br /> Model No.LGP 21401 Model No.LGP 21401 Mount antennas i <br /> &RRLIs to exist <br /> A (3)RRHs (3)RRHs <br /> Pipe mast within <br /> Model No.RRH2x4OW-07L Model No.RRH2x4OW-07L <br /> Model No.RRH2x60-1900A-4R Model No.RRH4x30-4R FRP shrouds <br /> i <br /> C Model No.RRH4x25-WCS-4R Model No.RRH4x25-WCS-4R <br /> (2)Diplexers (2)Diplexers <br /> (2)Raycap Surge Suppressor l (2)Raycap Surge Suppressor <br /> Model No.DC2 I Model No.DC2 <br /> 250 4th Avenue South,Suite 200 <br /> Edmonds,WA 98020 <br /> ENGIIERING <br /> ph.425.77&8500 ( f.425.778.5536 <br /> +vww.cgengineering.com <br />
