I am curious if any other general contractors deal with this issue. We collect supplier waivers in arrears, so we don't have subs enter any supplier amounts on their first pay application. We have realized this may cause an issue for subcontracts that are billing a large portion of their contract for materials on pay app #1. Roofing would be a good example. As a result, we could be paying them 70-80% of their contract amount without collecting any waivers. This puts us (the GC) at potential risk since we have not received any supplier waivers. We were wondering if there is a way to apply payment hold for missing current period waivers only for specific subcontractors to prevent this risk.
