I'm trying to evaluate the cost of helical piles for foundations in the tri-state area. The name of the job is private, but I have created simplified subsurface profiles. I want to know the approximate cost per pile at each site and the minimum clearance from the sheet pile wall. The plates drawn are for artistic purposes only, and are neither representative of the plate size nor the anticipated depth to the bottom of the piles. We want to withstand 10 kips in tension and 20 kips in compression, allowable loading.

I would really appreciate if someone can help me out. We also asked a distributor but he might not provide the answer in time. We need to answer our client ASAP.
