sample scope for commissioning ser vices (continued)
16. Approve air and water systems balancing by spot testing and by reviewing
completed reports and by selected site observation.
17. Coordinate functional testing for all commissioned systems and assemblies.
Witness and document manual functional performance tests performed by
the Construction Contractor for all commissioned systems and assemblies,
except: a) some smaller equipment may be tested and documented by the
Construction Contractor at the Commissioning Agent's discretion, b) electrical
equipment testing and regulated testing may be directed and documented by
the Construction Contractor with only spot witnessing and report review by the
The functional testing shall include operating the system and components
through each of the written sequences of operation, and other significant modes
and sequences, including start-up, shutdown, unoccupied mode, manual mode,
staging, miscellaneous alarms, power failure, security alarm when impacted
and interlocks with other systems or equipment. Sensors and actuators shall be
calibrated during construction check listing by the installing contractors, and
spot-checked by the commissioning provider during functional testing. Analyze
functional performance trend logs and monitoring data to verify performance.
Coordinate retesting as necessary until satisfactory performance is achieved.
Tests on respective HVAC equipment shall be executed, if possible, during both
the heating and cooling seasons. However, some overwriting of control values
to simulate conditions shall be allowed. Functional testing shall be done using
conventional manual methods, control system trend logs, and readouts or stand-
alone dataloggers, to provide a high level of confidence in proper system function,
as deemed appropriate by the Commissioning Agent and GSA.
18. After manual testing and initial trouble shooting is complete, monitor system
operation and performance for selected data points for up to two weeks by
requesting trend logs from the Construction Contractor from the building
automation system. For needed system points not able to be trended by the
building automation system, furnish and install temporary portable data loggers
that will monitor up to 20 points. Analyze monitored data to verify operation and
performance and issue a written report. This time frame and monitoring points
may be modified to accurately commission the building.
19. The final acceptance tests of all fire protection and life safety systems shall be
witnessed by the GSA Fire Protection Engineer or their designated represen-
tative. Testing and commissioning for the fire protection and life safety systems
shall be per the requirements of those sections of the specifications and the
