The commissioning agent develops a commissioning plan based on the OPR, BOD and commissioning meeting. The commissioning plan works as the guidebook of commissioning for the rest of the team. It demystifies the process and lists the responsibilities of the design and construction team. The plan discusses the roles of key team members, includes the latest versions of the OPR and BOD, specifies system sampling rates, anticipates pitfalls, and provides a commissioning schedule. In addition, the commissioning agent provides a general commissioning schedule based on the design and construction schedule that may or may not be defined at that moment.
