[TowerTalk] Speaking of structure issues

[Pete Smith]

I was out working at the base of my tower yesterday (97 feet of Rohn 25), and was surprised to discover that the base concrete block - poured to Rohn specs -  is visibly tilted.  Because I have a pier pin base, this isn't a big concern - the hole in the base for the pier pin is more than large enough to handle the misalignment - but I was wondering what would have happened if I had used a rigid embedded base section.  Maybe the concrete block wouldn't have tilted.

The tower is in an old river bed, with about 5 feet of spongy topsoil, and it gets pretty squishy nearby in the spring.  Fortunately, a guyed tower base isn't called on to take much but vertical loads.
