1. Best Practices of
Commissioning to Follow
During theTurnover Phase

2. Commissioning -Turnover Phase
• The turnover phase of any construction project is a well-ordered shift
of building operations to the operation and maintenance (O&M) team
from the project commissioning management services team.
• This transition is physical, signifies completion of commissioning-
specific activities and involves knowledge transfer in the form of
documentation.
• A successful transition is said to occur when the commissioning-
specific documentation is complete, fully organised, building systems
are operable as per the design and O&M personnel are trained
appropriately to operate the systems.

3. Up to Date As-Built Documentation
• Construction projects are largely directed by design documents that elucidate
and describe countless working elements that require to be put together for a
successful turnover.
• The global commissioning management authority requires to be updated about
the modifications as they impact commissioned equipment and gets updated
documentation from the project team.
• The commissioning authority is not accountable for updating design-specific
documents, but they are responsible to ensure that red-lined updates are
reflected well in as-built drawings given to the owner – particularly, mechanical
as well as controls as-builts.
• As-builts provide the O&M personnel with comprehensive information, using
which they fix system problems, locate equipment, trend the performance of
equipment and transfer knowledge to new personnel as and when needed.

4. Well-Structured Commissioning
Documentation
• Similar to design documents, commissioning documentation should
showcase the real conditions of the commissioned systems.
• At the least, the commissioning final report should consist of the
Commissioning Plan and Performance Verification Criteria, Pre-
Functional (PFC) and FPT notes, the Commissioning Issues Log and a
letter of acceptance, along with supporting documents like Testing
Adjusting and Balancing report, site visit reports, etc.
• The FPT and PFC notes are crucial resources that could aid present and
future building operators in developing a systems manual (if not
provided in the turnover phase) and help them with re-commissioning,
three to five 5 years post turnover.

6. Providing a Systems Manual
• As part of the turnover package, the systems manual is not needed,
unless the project seeks LEED Enhanced. Having said that, it’s
another important resource that may ensure a successful turnover.
• Moreover, a systems manual should ideally include riser diagrams,
control sequence highlights and control drawings. It is basically a tool
that can be utilised by O&M personnel for troubleshooting,
operating, and maintaining and monitoring building performance.

7. Developing a Re-Commissioning Plan
• In general, the re-commissioning plan should detail the following:
Overview of the on-going commissioning process
Responsibilities and roles of the commissioning team
Schedule of re-commissioning
List of the systems involved
In-depth instructions for the replication of FPTs, implemented by the
commissioning authority in the Acceptance phase.
Re-commissioning documents to monitor outcomes
Instructions and recommendations to set and track facility performance
benchmarks
