SECTION 230910 MECHANICAL SYSTEMS COMMISSIONING: continued
1. Meet with the TAB contractor prior to beginning TAB and review the TAB Plan to determine
the capabilities of the control system toward completing TAB. Provide the TAB
any needed unique instruments for setting terminal unit boxes and instruct TAB in their
use (handheld control system interface for use around the building during TAB, etc.).
2. For a given area, have all required pre functional checklists, calibrations, startup and selected
functional tests of the system completed and approved by the CA prior to TAB.
3. Provide a qualified technician to operate the BAS to assist the TAB contractor in performing
TAB, or provide sufficient training for TAB to operate the system without assistance.
G. Control system checkout and testing by the BAS Contractor shall be performed in the following
manner:
1. Startup Testing: All testing listed in this section shall be performed by the BAS Contractor
and shall make up part of the necessary verification of the operating control system.
This testing shall be completed before the Owner’s Representative is notified that the system
is ready for demonstration.
2. The BAS Contractor shall furnish all labor and test apparatus required to calibrate and
prepare for service of all instruments, controls, and accessory equipment furnished under
this specification.
3. Verify that all control wiring is properly connected and free of all shorts and ground
faults. Verify that all terminations are tight.
4. Enable the control systems and verify calibration of all input devices individually. Perform
calibration procedures per manufacturer’s recommendations.
5. Verify that all binary output devices (relays, solenoid valves, two-position actuators and
control valves, magnetic starters, etc.) operate properly and that the normal positions are
correct.
6. Verify that all analog output devices (I/Ps, actuators, etc.) are functional, that start and
span are correct, and that direction and normal positions are correct. The Contractor shall
check all control valves and automatic dampers to ensure proper action and closure. The
Contractor shall make any necessary adjustments to valve stem and damper blade travel.
7. Verify that the system operation adheres to the Sequence of Operation. Simulate and observe
all modes of operation by overriding and varying inputs and schedules. Tune all
DDC loops and optimum Start/Stop routines.
8. Check each alarm separately by including an appropriate signal at a value that will trip
the alarm.
9. Interlocks shall be tripped using field contacts to check the logic, as well as to ensure that
the fail-safe condition for all actuators is in the proper direction.
10. Interlock actions shall be tested by simulating alarm conditions to check the initiating
value of the variable and interlock action.
H. The BAS Contractor shall prepare a written plan indicating in a step-by-step manner, the procedures
that will be followed to test, checkout and adjust the control system prior to functional
performance testing, according to the process in Section 019113. At minimum, the plan shall
include for each type of equipment controlled by the automatic controls:
1. System name.
2. List of devices.
3. Step-by-step procedures for testing each controller after installation, including:
