The contractor breached the contract. He deviated the contract and left the smoke and burned truss and plywood in the roof to make more profile for himself, also the 2 months schedule complete the work expired which screw my all the plan. Can I take out the amount which he didn't use for the work, also How to claim and calculate the schedule delay (dollar/per day) loss amount? Can the contractor file a lien to against me if I don't pay him the full amount?
