I started the work as an employee of a structural engineering company, when I left the owner's representative asked me to complete the project. the structural engineering firm is now refusing to pay me.

I'm not entirely following the question here. If I understand correctly, you worked for an engineering company that was hired to do work for a project. Something occurred and you left the engineering company, but were retained by the owner to complete the project. You are now being unpaid by the engineering company.
For what work is the engineering company failing to pay you? If you left the company and did work for the project on your own under a contract with the property owner, you may be able to claim a valid lien against the property if you are not getting paid for that work (by the owner) - provided the notice and timing requirements are met. But, based on the information provided it's unclear why the engineering firm would be obligated to pay you for work after you left.
