• 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 theyre 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.
