Does anyone have a rule of thumb for using less than 3 piles (helicals, 
in my case) under a pile cap?  I've got a condition where I have some 
lightly loaded pile caps - about 45k - but their supporting pyramidal 
piers which have a 40" square base.  The tops of the piers will support 
a beam line and concrete plank, so there's no lateral loads.  The piers 
are 16-20' apart and are in a (roughly) straight line, so I can't 
efficiently combine multiple piers under a single footing.
