Why Commissioning Authority Should Complete Commissioning Checklists
Instead of contactors, the completion of commissioning documents should be done by the commissioning authority (CxA) – and for good reason!
Typically the commissioning management services company is in direct contract with the owner of the building and it acts as an independent, 3rd-party representative who ensures that the entire commissioning phase is completely unbiased and follows best practices while working towards achieving the project requirements of the owner. The commissioning authority bears the responsibility to assist the project team during construction, acceptance and design phases, which ensures that the project achieves success, but without being dependent on the construction and design teams, so as to maintain objectivity.
The commissioning process needs the
commissioning authority to develop testing procedures, data forms and
checklists, and record performance criteria. In general, these materials are
handed over by the commissioning authority to members of the project team. The
materials are further passed on to sub-contractors – and then their
installation contractors complete and return the documentation for review.
Surely, Not an Unbiased
Approach to Commissioning!
This make things complicated for the commissioning authority who may then have
to approach various members of the project team for different kinds of
documents that need to be reviewed and confirmed by the commissioning authority.
It is important to ensure that contractors should not complete the
commissioning documentation, such as pre-functional checklists (PFC)
–obviously, because they’re not the independent commissioning authority.
If contractors take the responsibility to
complete commissioning documentation, the building owner will not reap any
benefits from the true value of commissioning. When the commissioning authority
are responsible for completing commissioning documentation, they are required
to completely understand equipment specifications and choice, design details,
installation requirements from the manufacturers, identify any access
limitations in future, and describe their findings in a crisp and clear
fashion. Also, during commissioning coordination meetings, this documentation
needs to be provided to the project team for review.
Appropriate Role of
Contractors in the Commissioning Process
Contactors should give the required
equipment and initial documents to the commissioning management services
agency. They should also ensure their availability during PFC site visits and
make the required repairs, if the installation of equipment is not in line with
the design requirements, while meeting their general contract obligations. When
the commissioning authority works on PFC documentation, issues can be
identified and fixed quickly, documentation offers more detail and the project
team can go into the acceptance phase confidently with unbiased quality control
offered by a good global
commissioning authority.
Completing Commissioning
Documentation Is No Mean Feat
Completing commissioning documentation
needs an exhaustive database of mechanical equipment, including air handlers,
boilers, expansion tanks, cooling towers, and every imaginable piece of MEP
equipment within a commercial setting. For every equipment piece, the
commissioning authority requires to place the nameplate(s) to verify
manufacturers’ data accurately. This piece of information shows that the
equipment conforms to the authorised equipment submission and could be used in
the equipment inventory database of the owner. Once the equipment is installed
completely, the commission management services firm requires to return and
check if the installation is in line with the design requirements.
Reputed global commissioning firms make
use of design details from contract drawings and follow best installation
practices for every piece of equipment. These may include verifying if the
equipment has isolation valves for servicing, disconnects are accessible and
labelled, all pipe fittings are supported properly, piping supports coil
changes and protective shrouds are installed. The list is exhaustive for every
kind of equipment and such levels of details are also needed in functional
testing documentation.
Completing Commissioning
Documentation Is a Time-Intensive, All-Inclusive Process – Even for the
Commissioning Team!
Imagine how difficult it would be for the
contractor to get time to document precisely every piece of equipment when they
too have their own responsibilities with respect to the project they are
involved in. Accuracy, efficiency, comprehensive verification and unbiased view
are to name a few of the reasons why reputable commissioning management
services stress on completing commissioning documentation. Contractors are made
fully aware of their tasks and responsibilities. Installers know that they have
the time to concentrate on their work and building owners have the reassurance
that their project is being commissioned by a dedicated team of experienced
professionals.
