How much did your build run over cost?
We are just starting construction. I know that many say to expect cost overruns of 10-20%. As everyone, we're hoping to avoid overages as much as possible. We have a lump sum contract with allowances for certain categories. Before signing the contract, we priced things out and feel pretty confident that we can stay within our allowances. They've done excavation and didn't hit rock or have any other problems. So, I'm hoping with a fixed price contract that we can end up pretty good...again, as long as we stick with our allowances.
So, how much did you go over budget with your build? What were the reasons for the overages? Thanks!
