We are in a multi phase project, on Phase 3 of 6. We are almost done with Phase 3 and still have not received final payment on Phase 2. IS this a point we many use the 90 day mechanical lean to push for payment? But since we are not complete with our work do that void the availability to use this lean? If we stop work can we apply the above timeframe and lean? Than once payment is received can we start work again? We want to be able to receive the billing paid and continue the project.
