1. Pre-Design Phase

Develop owner's project requirements (OPR)

The owner's project requirements form the foundation and purpose of the commissioning process.  The commissioning authority must give thorough consideration to all aspects of the project to be sure all of the owner's requirements are detailed and documented.  This key piece of the project will be a living document that may change at various stages of the project depending on parameters such as budget, funding availablity and project schedule.  

Identify scope and budget for commissioning

Commissioning is a process to verify the owner's project requirements are being met at all phases of the project.  This is a risk management program and as such the owner must define the level of risk they are willing to take.  The lower the risk tolerance the more involved the scope of commissioning.  A higher tolerance of risk will require less commissioning activities.
 
Therefore, it is crucial for the commissioning authority to work closely with the owner to understand their risk tolerance and clearly define a scope of work to match.  Often times, the owner's risk tolerance is closely related to their budget for commissioning services and again the commissioning authority must ensure the owner understands and agrees to the scope.  

Commissioning plan

With the scope and budget defined and approved, the commissioning authority outlines a plan to execute that scope.  Initially, the plan will address activities, roles and responsibilities, schedule, and deliverables for the remaining pre-design phase as well as design phase.  This plan will ultimately become the complete plan including construction and occupancy phases of the project.
