The structured process of verifying, testing and preparing systems for safe operation before handover to the owner or operator.
Commissioning is the systematic process of verifying that facilities, systems and equipment have been installed correctly, tested thoroughly and are capable of operating safely and reliably in accordance with design requirements. It bridges the transition between construction and normal operations through inspection, testing, documentation, system completion and operational readiness activities.
Commissioning ensures that new or modified facilities are safe, functional and ready for operation while minimizing startup risk and improving long-term asset reliability.
Commissioning typically follows Mechanical Completion and includes activities such as loop checks, functional testing, performance testing, documentation verification and operator training prior to startup and final handover.
Commissioning is the overall lifecycle phase encompassing multiple activities and should not be confused with Mechanical Completion, which confirms that construction work has been physically completed.
