We are a first tier subcontractor on a project which is bonded. We were last on the project August 26th. We want to file a claim for the total amount due to us including retained funds and it's not clear to me what needs to be filed and whether or not it must be filed within 30 days of the last day worked on site. Also, we do not know who the Surety is on the Prime Contractor's Payment Bond (presumed, since we had to put up performance and payment bonds ourselves).
