An interesting article in MRT for April 1, 2007 > < dealing 
with grounding of 
structures and downleads and the Ufer ground includes a photo  (Fig-4) showing 
lightning damage to a 
concrete tower pier due to lightning surges through the foundation.  It 
cautions against use of a 
Ufer ground consisting solely of the tower foundation.
