Foundation: <br /> Due to the lack of information regarding the <br /> existing foundations for the anchors and tower <br /> base, we are not able to comment on their capacity <br /> at this time. Further subgrade inspection is <br /> required to determine their capacity. It is <br /> the tower owners option and responsibility to <br /> complete this subgrade inspection. <br /> Comte; <br /> The 700 ' Rohn 80 guyed tower located at Arden Hills, MN does <br /> not meet the specifications of TIA/EIA-222-F considering 80 <br /> mph wind and 1/2" ice with reduction allowed. This is based <br /> on all information as supplied to EEI being correct and <br /> current. If tower loading is changed or altered in any way, <br /> we suggest an additional analysis be completed. <br /> Some of the stress rations outlined in this report are large <br /> enough that permanent deformation to some of the tower <br /> members could occur if the analysis conditions were encoun- <br /> tered. Due to the large degree of overstressing we feel <br /> modifications are not feasible nor recommended to accommo- <br /> date the ice loading. <br /> It is our opinion that if the subject tower must have ice <br /> Included in the analysis, we suggest the tower either_ be <br /> replaced of shortened to a height where it can safety sup- <br /> port the antenna loading and have ice included. <br /> We dg recommend that the lower owner excavate adjacent tom, <br /> the existing anchor shafts to inspect or excessive rust. <br /> lSa_gS notethe shafts should be inspected AU tja wav 12 <br /> the point when n entershag concrete.
