| Do you have a general contractor or did you decide to be your own GC? |

| Kile, It is a general contractor, building a house for my daughter. I have never built, so I can not offer much advice other than documentation, thanks |

Concrete slab cracks are mostly due to the lack of an expansion joint placed on approximately 20-25 ft centers. Sometimes they can be due to the use of a lower weight PSI materials. ( i.e. 2500# in lieu of 4500# or similar comparisons.)
If the crack is what is known as "crazing" and does not go through the entire slab, it may not be a concern. (Incidentally, what IS the concern?)
Another consideration is the water table level, and whether or not the building, if necessary, has had a drain system installed. This may be a "French drain" type installed on the exterior, or a floating slab in which case the actual slab does not tie into the walls but "floats separately" and the area surrounding the slab allows for drainage. Is there a sump pump installed of provided for or required?
Not having a set of plans, copy of the contractor/owner contract, nor information regarding the soil conditions, or photos of the alleged damage, it is difficult to make an informed decision.
Suggest you contact the local building inspector's department for their input.

| All foundation/footings and interior/exterior slabs with or with out expansion joints cut into the slab will crack. It is the nature of concrete. You can contact your local building department and ask them what are industry acceptable allowances for concrete cracking. The allowance varies depending on the load bearing the concrete is supporting which determines the mixing requirements of the concrete. |
