It is <br />the tower owners option and responsibility to <br />complete this sUbgrade inspection. <br /> <br />~omments <br /> <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 EEl being correct and <br />current. If tower loading is changed or altered in any way, <br />we SUggest an additional analysis be completed. <br /> <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 />teredo Due to' the large degree af averstressing we feel <br />( madifications .are nQt feasible nar recammended to' accamma- <br />da~~ th~ ice laading. ' <br /> <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 af shortened to' a height where it can safety sup- <br />port the antenna loading and have ice included. <br /> <br />~ QQ recommend 1hA1 ~ tower owner excavate adiacent ~ <br />~ existinq anchor shafts 1Q inspect ~ excessive rust. <br />Please ~ ~ shafts should ~ inspected All 1D& HAY ~ <br />the point ~ ~ enters ~ concrete.
