Total System Commissioning
. . . in New Construction.
It makes good sense and it is to both your short- and long-term
advantage to bring the Certified Commissioning Authority (CCA)
into the planning process as early as possible - ideally at the
time you select the design team. Selecting the CCA that early
gives you an additional source of expertise to assure properly
operating HVAC and other systems for your project. After the
systems have been selected and final schematics have been made,
but before working drawings have been completed, the CCA helps
develop the functional performance testing requirements and
recommends system components needed to perform the testing. The
CCA prepares a Plan detailing how the commissioning process
will be organized and scheduled. When you approve the Plan,
it will be included in the contract specifications. The Plan
includes, but is not limited to:
- The requirement that the CCA review the design drawings
before bid time to make sure they include all necessary system
components (such as test ports, flow stations, balance valves,
access doors, dampers, etc.) to test, balance and commission
the project.
- The number and sequence of field inspections to be conducted
and documented by the CCA to verify that components needed for
proper balancing and commissioning have been installed. The
CCA will schedule and attend job site construction meetings
whenever necessary to benefit the project or when requested by
another job site meeting attendee.
- A description of the responsibilities of other parties
involved in the commissioning process. For example:
| |
The control contractor will provide a technician who is
thoroughly familiar with the project's control system to
assist the CCA as required during the commissioning process.
|
| |
All parties involved in the construction process – mechanical,
sheet metal, plumbing and electrical contractors, their
sub-contractors and material suppliers as well as the design
professionals – will cooperate in the commissioning process by
providing prompt assistance to the CCA as required to start
systems and equipment and correct any problems.
|
| |
All parties involved in the construction process as well as the
design engineer and the operating and maintenance people, will
cooperate in the training process. While the CCA is responsible
for scheduling and conducting the 0 & M training, others will
be responsible for providing the expertise in their specialty.
|
- Prior to final testing and balancing, the CCA observes and
verifies start-up of all equipment that will be included in
that process.
- The CCA verifies and certifies the final testing, adjusting
and balancing.
- After construction is complete and system(s) have been
commissioned, the CCA schedules and conducts the 0 & M training
program.
- When the project and commissioning process is complete, the
CCA submits all commissioning documentation to the owner and
recommends final acceptance of the building's system(s).
- During the guarantee period, the CCA is available to answer
questions, investigate building-related problems and recommend
the proper corrective action.
- The CCA assists the mechanical, electrical and sheet metal
contractors with their responsibility for providing as-built
drawings by informing them of any changes from design found
during the commissioning process.
