Re: [TowerTalk] 50 ft self supporting tower

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

My city required 90 MPH wind calcs per IBC-2000.  UBC-97 specs were 
rejected.  They will most likely require the calcs to be wet stamped 
by a PE licensed in your state.
If you are buying a new tower get these calcs and a bldg permit before 
ordering your tower.  I started with US Towers.  They provided 75 MPH 
wind calcs under UBC-97 codes.  Not acceptable.  I asked US Towers for 
the 90 MPH wind calcs.  They said they needed to go to an out sourced 
PE to do the calcs for $250.00.  I told them go ahead.  After 3 
months, many phone calls and emails still no 90 MPH calcs.  Was 
finally told NO US Towers crank up would pass 90 MPH calcs.  Went to 
Heights Towers in FL, got the wind calcs for the tower I wanted OK. 
It is now in the air.
