Retain age is a common practice in the construction industry whereby a portion of the contract price is withheld by the owner until the project is completed and inspected. The purpose of retain age is to ensure that the contractor completes the project and meets the quality requirements. The Release of Retain age Request is used to document the completion of the project and request the release of the remaining funds. There are two types of Release of Retain age Request: Partial Release and Final Release. A Partial Release is typically used when a portion of the contract work is completed and the contractor is requesting the release of retain age for that portion of the work.
