I'm not sure if this falls under supplier to supplier category, but I think it may. We are a materials supplier and are considering working with a concrete plant where the materials we supply and deliver will be blended into the concrete that is then delivered out to another job site. I believe we would fall as a Tier 1 supplier and my question would be can we file against the job where the concrete was delivered if we do not receive payment from the concrete plant who originally hired us to deliver the material to be blended?
