Section 19:6-2.35 - Minimum spacing of piles

(a) Piles shall be spaced to meet the following requirements:

1. Spacing of piles shall provide for adequate distribution of the load on the pile group to the supporting soil, in accordance with the provisions of section 42 of this subchapter.

2. In no case shall the minimum center-to-center spacing of piles be less than 24 inches, nor less than the values for specific types of pilings as indicated in section 48 of this subchapter. Unless special measures are taken to assure that piles will penetrate sufficiently to meet the requirements of section 32 of this subchapter without interfering with, or intersecting each other, the minimum center-to-center spacing of piles shall be twice the average diameter of the butt for round piles; or, for taper piles, twice the diameter at a level 2/3 of the pile length measured up from the tip. In cases of practical difficulty, the spacing of new piles from existing piles under an adjacent building may be less than the above values provided that the requirements relating to minimum embedment and pile interference are satisfied and that the soil under the proposed and existing buildings is not overloaded by the closer pile grouping.
