The commissioning process during construction requires the cooperation and coordination of all parties associated with a design and construction project. This includes, at a minimum, the general contractor, subcontractors, the owner’s project manager, the owner’s operations and maintenance personnel, and the commissioning consultant.
Typically, it makes sense to require that the general contractor prepare a master construction schedule first and then insert the commissioning milestones into it. A good commissioning specification will “tie” the required execution of commissioning tasks to standard construction milestones. For example, O&M manuals could be specified to be submitted 90 days following approval of the system shop drawings. Training could be specified to be conducted no later than 30 days prior to substantial completion.
