Utilize this 31 62 19 Timber Piles specification section to specify machine-driven, treated woodpiles for foundation use.
Machine-driven treated woodpiles are used in some locations as foundations for structures.
Wood for foundations should always be preservative treated to reduce deterioration and loss of support.
Prepare specifications based on the findings of a geotechnical report prepared by a licensed geotechnical engineer and in conjunction with the project structural engineer.
Since the final depth of piles can vary significantly, work is often specified on a unit price basis. A design depth is established for bidders to base their bids on, with the final depth used for payment purposes.
