The site is an existing installation that is <br /> in the process of being upgraded. <br /> The proposed installation consists of the following equipment: <br /> • Three new Sprint 800/1900 MHz NV Antenna (weight=29.8 pounds/each)and 3 new Sprint 1900MHz <br /> RRU (weight=65 pounds/each) installed on an existing antenna frame mounted on an existing <br /> chimney. <br /> • One new Sprint BBU Cabinet(weight=2500 pounds/each) and one new Sprint MMBS Cabinet <br /> (weight=660 pounds/each) installed on an existing concrete slab-on-grade platform. <br /> Our review was based on information provided by Vinculums, including Structural calculations by Victor H. <br /> Rimsey Consulting Structural Engineers, dated 7-11-97, as-built drawings from KDC Architects dated 10-21-98, <br /> and 100% installation drawings dated 7-30-12. <br /> Based on our review,the structure and mounts are adequate to support the installation as proposed. <br /> • The HILTI KWIK Bolt-TZ anchors shown in detail 2/A-9 are placed at each corner of the cabinets(4 total <br /> per cabinet). <br /> • The existing antenna mount shown on detail 2/A-4 has a minimum of(10)%"diameter adhesive <br /> anchors to masonry.This needs to be verified by the contractor who performs the installation. <br /> Sincerely, <br /> DCI Engineers <br /> r <br /> .� <br /> 7, 21757 '��. .r <br /> O <br /> �JONA.. <br /> Wade Younie P.E., S.E. <br /> Principal <br /> Enclosure:Structural Calculations <br /> 818 Stewart Street,Suite 1000 Seattle,Washington 98101 Phone(206)332-1900 <br /> S e r v i c e I n n o v a t i o n V a I u e <br />
