Worked on a public project as a sub of a sub that the GC hired, My job was to do installation but I ended up having to provide some materials along with some additional labor that was caused by their material supplier (sub who hired me). Was told to perform the work and send a bill which I did. The sub who hired me said that their material supplier would pay me but they are not paying and giving me the run around. This is a public project that did start over 45 days ago, The invoice is dated for the end of June. I did not file a notice to the GC however the GC does know I was on the property. Work has been completed at this point do now know what recourse I have.
