Hello,
What is the usual tolerance for cost estimates in quotes (legal practice?) regarding unforeseen conditions in the existing soil for earthworks?
At what point does a (non-)binding quote become invalid?
Is 20% or 40% miscalculation acceptable?
Probably, with fixed-price quotes, enforcement is difficult if significant unforeseen issues arise, such as unexploded ordnance or similar.
Does the risk related to the soil conditions lie with the client?
Does anyone have experience with this?

To respond once again to the original poster: So far, I have received four to five quotes from different civil engineering contractors for earthworks. All of them were divided by cubic meters, separated into: delivery and installation, clearing and disposal, and simple earthmoving.
The volume was only an estimate. In other words, the quote never referred to the final total cost, but only to the price per cubic meter. This way, the contractors avoid any risk...
