Commissioning refers to the process of bringing an item into operation and ensuring that it is in good working order. On building projects, this refers primarily to building services. As the post-commissioning structure suggests, there are eight stages of the commissioning process: preparation, design, pre-construction, construction, commissioning of services, pre-handover, initial occupation, and post-occupancy care. As the commissioning structure diagram illustrates, Commissioning activities in the broader sense apply to all project phases from the basic and detailed design, procurement, construction, and assembly.
