A commenter brought it up below and I received several emails on what the final contract price really was. Remember, the contractor was roughly half of what the other bidders were - $7.3 million or so. We were told the contractor would perform all the work for half the price two legitimate, longtime local contractors said they could do it for.
But you knew that.
Retainage on these projects is usually five percent of the total contract price. The retainage was about $450,000. That would mean the contract was for $8 million dollars. Unless they changed the retainage rules for this project, something went horribly wrong.
If they were paid $8 million and delivered the project a decade late, somebody needs to lose their job.
