This is an Unconditional Waiver and Release of Lien form for progress payments related to the Hazardous Waste Removal Services contract solicitation by the William S. Hart Union High School District in Santa Clarita, California. The document serves as a standard contractual instrument requiring contractors and subcontractors to waive all lien rights upon receipt of progress payments throughout the contract performance period. The waiver must be executed and submitted by the contractor prior to each progress payment disbursement to confirm that all labor, materials, and services have been paid for up to the payment date. Sealed electronic bids for this three-year hazardous waste removal services contract are due by 11:00 a.m. on Wednesday, April 29, 2026, with the contract anticipated for award on May 20, 2026, and commencement on July 1, 2026. The initial three-year term includes two successive one-year renewal options available to the District.

This waiver and release form is a mandatory contractual requirement designed to protect the District's interests by ensuring that all claims and obligations related to labor, materials, equipment, and services furnished are satisfied before progress payments are released. By executing this unconditional waiver, the contractor acknowledges receipt of payment for work completed through a specified date and relinquishes all mechanic's lien rights with respect to that payment. The form applies to all progress payments made during contract performance and serves as a condition precedent to payment authorization. Contractors and subcontractors must understand that execution of this waiver constitutes a binding release of lien claims for the amounts paid, and failure to submit the executed form may result in withholding of progress payment disbursements.
