We are a Prime Contractor. Public job. Florida. One of our Subcontractor's is in a dispute with one of his equipment suppliers (a sub-subcontractor). The Subcontractor does not hold a payment bond. We hold a payment bond as the Prime Contractor but have received a bond claim. The sub-subcontractor refuses to sign a current lien waiver. Suggestions? Can the Subcontractor provide a bond for the disputed amount in lieu of a lien waiver?
