Hello, We are a metal building construction company doing a project for a community college, therefore, a state/government job. We are a subcontractor under a general contractor. The general contractor is not paying us. The project is in the state of Iowa. I understand that a mechanic's lien cannot be filed as the property is not personal property. A bond claim will need to be filed. What is the procedure? We did not foresee this situation, therefore, a preliminary note was not delivered to the general contractor at the start of the project. How do we proceed with filing of a bond claim?
