I am a subcontractor to a mechanical contractor in Georgia. The mechanical has a large contract with a GC that is doing a project at a public College. We have completed our part of the work over three months ago and submitted for payment and got paid all but 10% of the project. The mechanical contractors contract is on going and they say that we cannot get paid until his contract is completed and he submits for payment for our retainage along with his. Is this correct or is he required to submit for our retainage since we have completed our part of the project before he submits for his retainage.?
