As used in project finance, the process by which a project or facility is tested to verify that it operates according to the design objectives, technical specifications and performance criteria set out in the construction contract. The commissioning process is typically done by the contractor prior to the transfer of the project or facility to the project company or owner. The determination of whether the commissioning requirements have been met is usually made by the project's construction manager or engineer.
