Frost heave at interior house footing

[ASCII]

I am having an addition built and the spread footing for a 28 foot long central girder has heaved. There are three concrete filled columns approx. 7 feet apart, and all of them have forced the girder to rise, one by about 1.5 inches. What should the builder do to correct the problem, cut the columns down, excavate the footing and pour a new one? The winter has been extremely long and cold, and the exterior wall foundation shows no signs of heaving. The footing depth is about 7' below grade but the interior footings were subject to freezing because the house is not insulated or heated yet. Any thoughts would be appreciated. ASCII

You need a registered soil engineer to make this decision. You probably need new foundations. But an experienced engineer needs to see it to make a proper determination

a 7 foot deep footing heaving? It may not be due to soil freezing, but somthing else. Good Luck, keep us updated
