Re: [TowerTalk] Hole Digging Question

["Alan C. Zack" <k7acz@cox.net>]

US Towers only rates their towers to UBC-97 specs at 70 MPH.  Many 
states/county/city Bldg Depts now require IBC-2000 90 MPH wind calcs. 
 I tried for 5 months to get 90 MPH wind calcs out of US Towers to 
satisfy my Bldg Dept and after going back and forth with their 
out-sourced PE I was told their towers cannot be rated under IBC-2000 
specs.  My suggestion is to check with your Bldg Dept for their 
requirements BEFORE ordering a tower.
