I am just wondering what're typical pier sizes for 4 ft and above? Do they all come in 6 in increments?
Is that normal to size pier diameter as 4' - 9" or 4' - 8"?
Some jurisdictions require shafts in excess of 30" or 36" if they require hand inspection or they may require that the caissons have a metal sleeve, too.
