ENGINEERING ROOFTOP ANALYSIS REPORT <br /> Mrs. Wendy Long <br /> Goodman Networks Carrier: AT&T <br /> 8815 122n0 Ave NE Carrier Site Name: Port Gardner <br /> Kirkland,WA 98033 Carrier Site Number: WA6299 <br /> Client Site Name: Port Gardner <br /> Client Site Number: WA299 <br /> Site Address: 1321 Colby Avenue <br /> Everett,WA 98201 <br /> Snohomish County <br /> (47.999839,-122.207489) <br /> PROJECT DESCRIPTION: <br /> AT&T proposes to add additional appurtenances and their corresponding mounts and coax lines to the existing <br /> above referenced rooftop. Appurtenances will have a 116'rad center. <br /> ANALYSIS: <br /> The purpose of this analysis is to determine if the existing rooftop structure is structurally adequate to support the <br /> proposed loadings and provide any recommendations for modification in order to bong the structure into <br /> compliance if needed. The structure has been analyzed in accordance with the 2009 International Building <br /> code. The additional design criteria used in our analysis is as follows: <br /> • 85 mph(3-sec gust) • Occupancy Category Ill <br /> • Wind Exposure C • Seismic Design Category D <br /> • Topographic Factor, Ke= 1.0 <br /> RESULTS: <br /> Based on our review of the existing structure with the proposed loadings, we have determined the following: <br /> Existing Roof Structure: Structurally Ad•quato <br /> Modified Antenna Mounts: Designed per Code <br /> Please refer to Appendix A for structural calculations supporting the above results. The structural calculations <br /> also include design calculations for the design of the new framing/mounting. Upon Client approval, PTS is <br /> available to create the associated structural construction drawings. <br /> We trust this addresses your concerns. Please contact us if there are any questions. <br /> ,�� . scttb-- <br /> < s-" 1 <br /> ff <br /> r. <br /> M <br /> 9(Ntt <br /> Prepared By: Eric Schultz, P.E. <br /> Dated: April 11, 2011 } *r 4)K1v �, <br /> �Ssronnt.t•�•• <br /> Contents: <br /> Report 1-4 <br /> Appendix A (Calculations) A EXPIRES 4( s/'t 1 <br /> 568 First Avenue S, #650, Seattle, WA 98104 •(Phone)206.342.9000•(Fax)206.903.8513 <br /> SEATTLE I PORTLAND SAN FRANCISCO I COSTA MESA <br />
