INTRODUCTION
Building commissioning is a process for achieving, verifying, and documenting
the performance of a facility to meet the operational criteria of the contract
design documents. Its intent is to furnish the Owner with a high degree
of assurance that the equipment and systems have been installed in the
prescribed manner and will operate according to the performance guidelines.
Building Systems Commissioning, Inc. (BSC) will have contractual
responsibility to coordinate tests, verify and report on the operational
condition capability, and performance of the building's HVAC system, as well as
plumbing, electrical, communication, security and food service equipment.
The objectives of commissioning are as follows:
PRE-DESIGN PHASE
 | Development of preliminary commissioning plan |
 | Review of the owner's Design Intent Document |
 | Identify members of the Commissioning Team |
DESIGN PHASE
 |
Development of the commissioning
plan. This plan will consist of:
 |
Commissioning Team
responsibilities |
 |
Objectives of commissioning |
 |
Involvement during each phase |
 |
Anticipated time involved in each
phase |
 |
Scope of Work |
 |
Pre-Functional Checklists |
 |
Functional Performance Tests |
 |
Operation and Maintenance
Training Agenda |
|
 |
Design Review- attend meetings with
design professionals involved to identify any possible problems which would
prohibit successful commissioning of the systems. |
 |
Finalize commissioning
specification |
CONSTRUCTION PHASE
 |
Attend
on-site meetings with the commissioning team and conduct periodic walkthrough
inspections of the systems to be commissioned, as well as provide assistance
to the Seller in expediting the schedule for start-up. |
 |
Ensure, demonstrate and document
that all systems and subsystems included in the commissioning scope are
installed and are in compliance with the contract construction document. |
 |
Prepare a training agenda to assist
the Seller's efforts to ensure that operating personnel are properly
instructed and prepared to effectively operate the commissioned systems. |
 |
Coordinate with the commissioning
team to collect O&M manuals on all systems associated with commissioning.
The Company's maintenance team for O&M purposes will utilize these manuals. |
ACCEPTANCE PHASE
 |
Coordinate with the commissioning team to plan for system readiness and
functional testing of each system to be commissioned. Time will be
allotted for checking system readiness, test and balance work, and functional
testing so that the Seller can reasonably determine milestone dates for
Substantial and Final Completion. |
 |
Coordinate with the commissioning team to organize training for the Company to
operate and maintain systems to be commissioned. Vendor representatives
will need to be on hand for their respective equipment, as well as the
contractors involved in the installation of the equipment. The training
sessions will primarily be conducted by the contractors and vendor
representatives. Training can take place following functional testing,
but can also take place during functional testing. |
 |
Final
Commissioning Report- collect all results for system start-up, functional
testing, training, and O&M
manuals to submit to the Company for the Final Commissioning Report.
Included in the Final Commissioning Report will be a write-up on the as-built
system performance as well as a list of deficiencies. A list of the
off-season functional testing not performed and a schedule for their
completion will also be included. |
POST-ACCEPTANCE PHASE
 |
Off-season
system performance testing |
 |
Updated
As-built documents |
 |
Maintenance records |
 |
Modified
operating procedures |
 |
Log of
complaints, problems and corrective actions |
Commissioning Scope of Work
 |
Documentation checklists- The following documentation will be completed for
all systems and are components subject to the Commissioning process:
 |
Pre-Functional checklist- a checklist will be made for every piece of
equipment which is to be commissioned. This list identifies what to look
for in the way of installation and start-up of the equipment. It also
identifies which party is responsible for each checklist item. When all
items are checked off, the equipment is prepared for start-up. Test and
Balance is NOT to commence until each Pre-Functional checklist for HVAC
commissioning is complete. |
 |
Functional Performance Test- The Functional Performance Test is to be carried
out on all equipment to be commissioned. These tests may begin AFTER
Test and Balance is complete. Each FPT compares design performance to
actual performance. Once it has been proved that the equipment has met
design performance, the sequence of operations implemented by the design
engineer is tested to find out if the equipment responds as expected to
certain commands. This demonstration is to occur in front of the owner
so that the owner feels comfortable with what he is purchasing. |
|
The above listed documentation
sheets will be generated for each of the
following pieces of mechanical and electrical equipment:
 |
