The Basic Foundation of Your House
Your plan may not call for, or local building code may not require rebar to be placed in footings.
I always use them anyway because of the extra strength they provide.
In a 4000 sq. ft. house I recently built, placing a double run of rebar in every footing cost under $500. That’s money well spent for an extra strong foundation.
If your house will have a crawlspace foundation, you should hire one contractor who will layout, measure, and dig the footings, and pour the concrete.
His fee will probably be based on the amount of linear feet of footing.
His price may or may not include concrete.
Generally, it will be cheaper for you if you order your own concrete.
Your subcontractor should be able to fairly accurately estimate the amount of concrete needed.
If your deal calls for you to supply the concrete, determine a firm date for him to make the pour.
At least one day prior to pouring, alert your concrete supplier as to how much you’ll need and set up a delivery date and time.
If you can’t be there at pouring, authorize contractor to order more concrete as needed, on your behalf.
If the contractor is providing the concrete have rebar on site by the time footings are dug, so that he may have everything set up immediately.
