I am a Subcontractor on a large project who is still waiting to receive payment from the General Contractor for a draw in December. How long do I have to wait to receive a progress payment. My emails to them go unanswered. Also, how does a Subcontractor find out if a General Contractor has been paid by an owner to make sure the Subcontractor is getting paid on time and the General Contractor is not delaying releasing payment?
