ITA with Carli that having super detailed plans will resolve some of the disputes. But then again, you have to supervise to make sure that those details are delivered.
We’re currently trying to resolve 4-5 things, that were specified and not delivered, on our “finished” project. We withheld some of the final payment, they put a lien on our house and arbitration or court is likely in our future. Fortunately, our attorney assures us that since the changes were not authorized and the plans are clearly specified, we’ll win.
Another point to consider. Most contracts from GCs call for binding arbitration rather than court. There’s no recourse (appeal) if the arbitration panel blows it, ignoring evidence. Our attorney also told us to strike out the arbitration clause and insist on court settlement. (His fees are pretty much the same either way, so it’s not a vested interest advice.)
