U.S.A. <br /> Eden Prairie, MN 55344 <br /> RE: Minc Navarre LTE <br /> 2345 Blaine Ave. <br /> Orono, MN <br /> BCG No. N1322091 <br /> Dear Mr. Windschitl, <br /> The following is our review summary of the structural adequacy of the existing support framing for the <br /> replacement of antennas at the above referenced Verizon site. <br /> The existing Verizon antennas are mounted near the catwalk of an existing steel water tower located in <br /> Orono, Minnesota. A total of twelve antennas divided into three sectors of four antennas each are <br /> supported by steel beams which span between the tower legs and each is connected to these legs. <br /> Two existing 90.5" tall antennas in each sector are proposed to be replaced with two new 95.7" tall <br /> antennas. Weight of the new antennas is about the same as the existing antennas. Sizes of the new <br /> antennas are slightly larger than the existing antennas. The new antennas will be mounted on the <br /> existing steel pipes <br /> Review of the structural impacts from the antenna replacement on the existing support framing has been <br /> performed and the existing support framings are adequate. <br /> If you have any questions, or if we may be of further assistance, please call me direct at 612-789-1313. <br /> Sincerely, <br /> Buildings Consulting Group,Inc. <br /> Louis K.
