The proposed loading includes the replacement of <br /> (3)Alcatel Lucent RRH2x60-850 RRUs with(3)Nokia AIRSCALE RRH 4T4R B5 160W AHCA RRUs. <br /> This review has been performed in accordance with the 2015 International Building Code based upon an <br /> ultimate 3-second gust wind speed of 110 mph. Exposure Category C with a maximum topographic factor, Kzt, <br /> of 1.0 and Risk Category II were used in this analysis. <br /> The project consists of proposed loading to replace existing equipment with like kind. Based on our assessment, <br /> the increase in loading from the equipment swap is minimal and within the capacity of the structure. In addition, <br /> the proposed additional load to the building structure does not increase the lateral demand capacity ratio the by <br /> the 10 percent criterion indicated in Sections 807.4 and 807.5 of the 2015 International Existing Building Code, <br /> and therefore,a full analysis of the building structure is not required. <br /> We at Morrison Hershfield Corporation appreciate the opportunity of providing our continuing professional <br /> services to you and General Dynamics Information Technology, Inc. If you have any questions or need further <br /> assistance on this or any other projects please give us a call. <br /> Respectfully submitted by: -i• S &1, <br /> Morrison Hershfield " ' t3 WAS/f/ 'e„1„, <br /> c? , <br /> Shawn W.
