A Construction Management Consultant to the GC on a project is demanding our customer Invoices and Proof of Deliveries (which we have) before issuing the Conditional Final payment amount. Our customer has agreed to an overall aging report on the job which we provided to them, but our customer does not want them to have the itemized Invoices. We value our customer and they do not want the information shared. Our Notice of Intent to Lien has been filed.
