A Washington Notice of Completion of Public Works Contract is a document used to certify that a public works contract has been completed in the state of Washington. A public works contract is an agreement between a government entity, such as a municipality or county, and a vendor for the construction, alteration, repair, or improvement of public works. The Notice of Completion is typically submitted by the contractor to the government entity that awarded the contract. The Washington Notice of Completion of Public Works Contract can be divided into two types: the first is a Notice of Substantial Completion, which is used when the contract is substantially complete, but minor work remains to be done; and the second is a Notice of Final Completion, which is used when all the contract work has been completed. The Notice of Completion must be signed by the contractor and typically includes information such as the name of the contractor, the date of completion, and the name of the project.
