Should be easy to fix, if the contract for work includes a "penalty for being wrong for circumstances completely within the bidders control that they should have seen". Austin government did this for its MoPac toll express lanes and got them for way cheaper than what they should have paid: https://www.bizjournals.com/austin/news/2017/09/27/big-settlement-reached-in-mopac-expansion-end-in.html https://www.bizjournals.com/austin/news/2017/09/27/big-settl... However, the project ran over for two years longer than it should have (it was supposed to be completed in September 2015, and they are only just now wrapping it up). So I guess no one really won there aside from the Austin transportation budget guys, except the populace hates them now for traffic jamming the place up for two years longer than they said they would.
