Often times the process of commissioning can be an ambiguous event that can have a different meaning for the variety of players involved on the project (e.g., owner, design engineer, contractor, etc.) Developing a commissioning program and documenting it in a commissioning plan helps clear up a lot of that ambiguity in order for all contractors, the commissioning team, the design team and the owner to understand the requirements and determine the expectation level for the project. The commissioning plan ensures that everyone agrees that the project will operate in accordance with contract documents and approved scope of work. The commissioning plan will highlight important general project information (location, building type and the construction period), critical abbreviations and definitions, identifies which systems or components are being commissioned and also identifies the project team members involved (including their contact information). The commissioning plan intends to focus on the commissioning process throughout the various phases of a project: design phase, construction phase, acceptance phase and post acceptance.
