Check if “unsuitable” soil/fill is really contaminated. It might me that it was just wet or not compact-able. It may not be contaminated.

Avoid paying for removal of “contaminated” material unless it really is. Some people will assume “unsuitable” means “contaminated”, this may not be the case.

Unsuitable (not contaminated) could be used for sound barriers, or other non structural areas.

For soils testing, get a map and list of where tests were taken so that you can see if that matches where your designs are to be constructed.

Some soils analysis companies may just take limited samples and extrapolate the results to cover the entire area. This may mean that when drilling is done for foundations, the soil is very different to what is expected.

Make sure these maps are clear.

Ideally they would have GPS coordinates for each test point, not just hand markings on maps (which may not be very accurate).
