[TowerTalk] Limitation on tower width. Was: Revocation ofBuilding Permit?

[Alan C. Zack]

Many states/counties/cities have gone to IBC-2000 90 MPH wind calc 
requirements.  US Towers is unable to provide these calcs to 
perspective buyers.  Their specs are to UBC-97 70 MPH wind calcs.  I 
tried for months to get 90 MPH wind calcs from them and was finally 
told they were not possible.
