On this project site located in Columbus, OH we supplied equipment to a general contractor on a federal project. At the point which (the subcontractor) had gone unpaid by the GC for 3 months, we sent in a affidavit claiming our amount against the bonding company in December 2019. We (the subcontractor) received a response that the claim was denied on 3/5/20 and put together a rebuttal with proof against the reasons given for claim denial and submitted this to the bonding company on 3/31/20; it was acknowledged on 4/4/20. this is the 7th week now and we have received small excuses from the bonding company like "we are getting to it" or "the bonded GC has outstanding questions to send back to us". I am concerned the bonding company is buying time. I am wondering how much longer (as the subcontractor) should wait before we begin a lawsuit process.
