The article offers information on one-to-one relationship between a system and its functional performance test (FPT). It mentions that normal electrical power system is invariably the first system to be tested in a new construction project. It states that commissioning scheduling needs to be customized for each project and its unique collection of systems to achieve a balance of efficiency, effectiveness, and coordination with the contractor's installation and start-up sequencing.

The article offers information on the Owner's Project Requirements document (OPR). Topics include granting approval for Leadership in Energy and Environmental Design (LEED) projects; closing the communication loop between owner and designer before construction; and providing target cooling and heating space temperatures and ventilation for various space types.

The article offers the author's insights on the post-construction functional performance tests. Topics discussed include the building design and construction, the project management, and the responsibility of the construction team for corrective actions on failure to meet the construction project requirements. Also mentioned are the design engineering services and the design failures management.

The article explores the reason why commissioning action lists (CALs) are difficult to control as well as examines what should commissioning professional do about it. It outlines the goal of the commissioning process to have the time to understand the owner's system performance requirements and the intentions of designers how the systems will achieve those requirements. The need for the contractors to review the test procedures and agree or disagree with the acceptance criteria is also tackled.

The article provides information on the role of the commissioning professional in an unrealistic construction schedule. It mentions that the commissioning professional can be an active voice of reason on what can be anticipated if there is not enough time scheduled at construction's end for startup, quality control and controls completion. The schedule feedback of the commissioning professional is most effective early during construction phase when it is easiest in adjusting the schedule.
