[TowerTalk] Guy Anchor Corrosion Question 1

[Tower2sell at aol.com]

Greeting All,

It has been several years since I posted on this board. At that time I was 
working for ROHN as an Engineer and hopefully I helped some of you with your 
ROHN questions. Because of ROHN's BK I have moved on and I am working for another 
consulting engineering firm. So much for the update.

While at ROHN I was always concerned about the anchor rods and in 2001 I saw 
the remains of a 27 year old 300+ tower that had collapsed at Morton, IL 
because of corroded anchor rod. 

I have since gone on a technology quest to find a method to nondestructively 
inspect the anchor rods without digging them up. I HAVE found it. I am 
currently doing a business plan and trying to assess the market and request your help 
in a series of discussion questions.

Question 1, Part A: Do you know of any towers that have collapsed because of 
corroded anchors?

Part B: Was there property damage to others?

Part C: Was anyone injured or killed?

Currently, there is not a single source for this information and any help 
will help. I do know about the Sioux Falls Tower incident where workers were 
injured riding the tower down.

Thanks,

Mark Johnson, P.E.
