Eventually, the weight of the building caused the top layer of soil to collapse.

The spire area of the Skydome was reinforced before work started on removing the final three buried cars.

[5] Multiple multigravity tests were done to ensure that another sinkhole wasn't present or in the making.

For an added precaution, micropiles, or systems of steel rods, were inserted into the ground before the concrete was repoured to help give the building more support.

This exhibit gives visitors the chance to virtually recover the cars that were in the sinkhole.
