Tlie site is an ezlsling inslallation Ihat is <br /> In the process of being upgraded. <br /> The proposed Inslallalion consists of Ihe(ollowing equipmenl: <br /> . Threa new Sprint 800/1900 Ml1z NV Antenna(weight=38.1 pounds/each)and Ihree new Sprinl <br /> 800/1800MHz RRU(xreight=65 pounds/each} InsteNad on new mounls on exisling support frames <br /> located on Ihe Norlhwest,Soulheasl,and Southwesl sides ol the bultding. <br /> . One new Sprinl BBU Cab(nel(weighl=2500 pounds/each)end or,e new Sprint MMBS 'abinet <br /> (weighl=880 pounds/each)inalelled on an ezisling sleel support treme. DCI recommends thal the <br /> cabinete be alteched to lho sleel support Irame wilh(4)'r4'minimum diameter A325 bolls. <br /> Our review was based on Information provided by Vinculums,including Iha Slructurel Cakulalion submilted by <br /> Nelson•Bourdeges Inr..,P.S.(daled 4/23198),As Buill drawings(daled 8/27/88),and Ihe 90°/a installalbn <br /> drawings(Jaled 7/24�12). <br /> The inflfel deaign cabinel weighl by Noslon Bourdeges for the plal(orm aupporting Ihe new equlpmenl was 7870 <br /> Iba and Ihe new cabinel weight fs 5540 tbs. Beaed on our review,the exisling cebfnet aupport freme,mounls, <br /> and rool fram(ng ere adequete to suppoA the inslallatlon.Aleo,lhe exlsting ballasl framea supportinp the <br /> antennes are adequate lo support Ihe inlerim and final eondilbns.Theae baNeat trames rely on the dead welght <br /> ot concrele blocks lo resisl sliding end oveAurning from wind end earthqueke loads.To resisl ove�luminp during <br /> Ihe inlerim condition Ihe requfred welghl ollhese bricks normelly aseumed lo welgh 150Ib/1l�,needs to be 2000 <br /> Ibs per side ot Ihe Irame.To resisl oveAurning during Ihe finel condilion Ihe requlred weight of Ihese bricks <br /> needa lo be 650 Ibs por side o11he ireme.The oxisling weighl of bricks musl be verified and bricks may naed to <br /> be added in order to moel these raquirements. <br /> � <br /> sincarety, O p� � <br /> DCI Englneers �<v � <br /> � ` �� <br /> �� �'' � � <br /> Greg Gilde P.E.,S.F.
