My company was subcontracted in to perform concrete work for a project back in March. The Senior Project Manager informed of the pay structure before starting. I asked questions to the Senior PM about the contract and he stated a certain section did not pertain to me. We both signed. After starting work, it came time for the first payment and the Senior PM changed the pay structure after he got clarification. I submitted the final invoice 6/2 after work was complete 5/25. The Senior PM has again changed the pay structure. He is responsible for getting materials there needed and has failed to do so throughout the project and is stating repairs needed, engineer inspections and turnover of the project is needed before I can receive the final check when i was not informed that until 6/9 when the final check was supposedly be received based off the Senior PM's relayed information to me. The job site is an hour an a half one way and I do not have funds to be sending my guys for nothing when he has not had materials on-site the last time I had a crew on-site to work. I am a small company that has been taken advantage of when I acted in good faith since the beginning in hopes to receive more work. His conduct, inability to schedule trades correctly, to communicate effectively, and order materials properly has obstructed my company’s ability to fulfill and profit from the work that needed to be performed.
