The pricing was based on a cleared level block ready for dusting and form. I have had a soil test done and discussion with an engineer about what was required with each design. His job is to design the foundation, and I was obviously trying to design a house with consideration to the foundation and how it will effect other parts of the house. When entering into a contract to build with a builder as far as I am aware, the cost of the slab is quoted in full, and a guestimate or allowance, is made on the depth/cost of piering, The issue being is that a soil test is not done directly in the location of each pier, and subsequently the depth of the piering may change to suit. The problem with piering is that because the contractor is can't be 100% sure of the foundation of the pier, mistakes are made. Too deep, waste of concrete, too shallow and no support for slab. I have think that screw piers should be considered. Re: Owner Building - What's a reasonable cost for the slab? 13Jan 03, 2018 8:38 am Arnie1989 I think it's going to be challenging to negotiate a better price for the following reasons - 1) I am owner-building, and do not have a huge quantity of work to use as a bargaining chip. ie. no buying power 2) The market is hot, so subbies can cherry pick jobs... why work for a smaller margin, when he's got 10 other job offers that he can charge a higher rate on? I'll keep trying, and see where it lands me. Here is my2c worth 1.Now what it's worth & have a fair price in mind say $30K 2. Pick a large contracting team 3. Plan your project properly 4. Develop a relationship with those quoting, prove you are not a Time waster costing them money 5. Make sure the site is ready to go anytime.. 6. Chances are he can fit you in between delayed jobs 7.

Probably worth giving them a call.
