Foundation issues - costs?

[Gretchen P.]

I am considering making an offer on a property that has some settling and foundation issues. All doors and windows operate correctly, and don't appear to be affected. The engineer's report says it will need 10-12 underpinning piers some of which would be located beneath the garage floor, so excavation would be required.

There are some interior drywall cracks and exterior cracks on the brick veneer. There is noticeable sloping of the floor on the main and upper levels. The engineer's report also calls for fixing grading around the property and replacing the sump pump.

What kind of costs will I incur for these items? The engineer's report says $2000 per pier, is that realistic? Are there other issues that will need to be addressed that I should account for prior to offering on this property?
