Introduction <br />B I l o(D-C)o9- <br />Curnmer, i.d <br />I n frae l rua lu re <br />R esi den lief <br />At the request of Goodman Networks, we have performed a structural analysis of the new and <br />existing ballasted antenna mounts at SN17 Eastmont in Everett, Washington. The evaluation <br />was completed in conformance with the 2009 International Building Code, the Steel <br />Construction Manual (AISC 13) and the American Society of Civil Engineers Standard 7-05 <br />(ASCE/SEE 7-05)under the following site specific conditions: <br />Basic Wind Speed: 85 mph <br />Exposure Category: B <br />Occupancy Category: II <br />Seismic Site Class: D <br />Based on our visual inspections performed on December 22, 2010 the existing ballasted antenna <br />mounts appear to he well maintained and relatively free of corrosion. This evaluation assumes <br />that the mounts were properly installed per the original design documents, and that they do <br />not overstress any roof structural elements. <br />The following sections detail the existing and proposed configurations in the areas subject to <br />change. <br />II.

Conclusion <br />The Y.;AW antenna is the worst case for both wind and seismic loads and was used in ollr <br />analysis.
