I have a contract to perform work on a project as a Subcontractor. Our contract states that " all work must be ready for the Subcontractor to complete all their work in one trip when the Subcontractor arrives on site." We were called, demanded and threatened with law suite, to come to the job and the GC did not have the job ready for the US ( the Subcontractor) to complete our work. The Site Superintendent assured us that the job would be ready when we arrived at the site. We got to the job 12:00 PM got our crew rooms and arrived on site at7:00. We are roofing contractors when we arrived the steel decking was not installed on the bar joist. The site super said his steel crew over slept and did not work last night. Short story. When we billed for the extra trip, overtime per diem, the GC is now saying the invoice is extra ordinarily excessive. Looking for advice to lien property. For extra Costs Roofing Contractor Gary
