Helical Pier Suppliers
Info Request
Hi,
We would like a quote for a 4200 lb-bearing helical pier foundation pile assuming clay soil. We need 27 of these for a small, one story stick frame house. We were intending to rent a bobcat driver for the piles. We are located in the Kansas City area. Please include cost + shipping (zip code 64469). Can you do this?
If you can do this as a contractor, we'd be interested in a quote as well. We will be building several houses, and we will do the helical piers both ourselves and by contracting out.
If you don't do this type of work, what is your top recommendation for somebody else?
Thanks, Marcin

We do not have engineering drawings, but I can provide technical detail. The exact weight of a 16x16 house section that we are building is 18,000 lb including 50 PSF snow load. Our soil is light clay with N=10. We are rural in Dekalb County, where we have no building codes, so we don't have engineering drawings. It's a simple light-frame structure. It is 4 sections of 16x16 feet, so 27 piles total. Here is our engineering, which indicates only 4 kips per pile:
Would this work for you to get us an estimate?

Quotes
- Helical anchors - $100 a pop -
, $6k total if 14' deep - 
- These are 7 foot sections, which needs to be determined for the depth required. Here we have 14, so half the piling may be ok, but need to do Helical Pile Calculations. The 2-3/8" OD 0.19 wall pipe is 1.4" of meat, or about 90 kips ultimate tension (at 60 ksi) and likely 45 kips working strength, so our requirement is much smaller.
