The Commissioning and Handover phase in EPC (Engineering, Procurement, and Construction) projects focuses on creating final documentation, such as Mechanical Completion Data Books and Dossiers, which include all necessary records, certificates, and test results to verify that the project meets its specifications.

During the handover, final data packages are issued to the project operator. These data packages include all necessary documentation to ensure a smooth transition from the construction and commissioning teams to the operations team.
