Unless you are a foundation contractor/engineer, it usually is not cost effective to do the repair. 

When you say "scrape the pad and bring in dirt", I do hope that's based on engineering specs.

I attended the US Merchant Marine Academy in Kings Point, NY, graduating with a degree in Engineering in 2002.

@Zach Wilson I'm a software engineer/data analyst.

Not only could the inspector refer anyone to me for a structural inspection, but all the structural engineers I called won't do anything during the home buying process to influence or discourage the buyers decision.

I'm a structural engineer with 8 years experience and 12 years or architectural development working in Northwest Washington, primarily on Whidbey Island, WA. 

Have a structural engineer on hand.

Most space engineering companies are there from Lockheed to NASA.
