Taking place at the final stage of the project, the close-out will see the appointing party archiving the project information model (PIM). Throughout this project, the asset information model (AIM) will be developed. Like the PIM, an AIM can contain geometrical information, alphanumerical information, and documentation to support the ongoing maintenance, operation, and management of the asset. More information on this process can be found in Section 4 of this document. This stage of the project also presents the opportunity to capture lessons learned for future projects.

This stage is broken down into a series of activities that will need to be completed in accordance with clause 5.8 of I.S. EN ISO 19650-2:

Archive the project information model

Once all delivery milestones have been achieved and following acceptance of the completed (PIM), the appointing party shall archive the information containers in accordance with the project’s information production methods and procedures. This will ensure that there is a definitive final version of the PIM available that can be retrieved by the appointing party after the project has been completed.

In doing this, the appointing party shall consider: the information containers needed as part of the asset information model (AIM), future access requirements, future access re-use, and relevant retention policies to be applied[1]. This activity should take place at project close-out.

Compile lessons learned for future projects

This activity offers the opportunity to capture lessons learned that support continuous improvement for future projects. In collaboration with each lead appointed party, the appointed party shall capture lessons learned during the project and record them in a suitable knowledge store that may be called upon for future projects.

While only the appointing party and lead appointed party are referenced in this clause, it is equally important that all project stakeholders are engaged in the contribution of lessons learned, taking into consideration the positive and negative outcomes of the project and areas for further consideration. Although this activity takes place last, it is recommended that any lessons learned are captured throughout the project and within the duration of an appointment.

Summary

By the end of this stage, the project team will have completed the delivery phase of the project, archived the project information model (PIM), and produced the asset information model (AIM). The success of the asset's operation and maintenance phase will depend on the information provided in the AIM.
