01 9113 General Commissioning Requirements 6 procedures.

B. Contractor is responsible for execution of required Functional Tests, after completion of Prefunctional Checklist and before closeout.

C. Commissioning Authority is responsible for witnessing and reporting results of Functional Tests, including preparation and completion of forms for that purpose.

D. Contractor is responsible for correction of deficiencies and re-testing at no extra cost to Owner; if a deficiency is not corrected and re-tested immediately, the Commissioning Authority will document the deficiency and the Contractor's stated intentions regarding correction.

1) Deficiencies are any condition in the installation or function of a component, piece of equipment or system that is not in compliance with Contract Documents or does not perform properly.

2) When the deficiency has been corrected, the Contractor completes the form certifying that the item is ready to be re-tested and returns the form to the Commissioning Authority; the Commissioning Authority will reschedule the test and the Contractor shall re-test.

3) Identical or Near-Identical Items: If 10 percent, or three, whichever is greater, of identical or near-identical items fail to perform due to material or manufacturing defect, all items will be considered defective; provide a proposal for correction within 2 weeks after notification of defect, including provision for testing sample installations prior to replacement of all items.

4) Contractor shall bear the cost of Owner and Commissioning Authority personnel time witnessing re-testing.

5) Contractor shall bear the cost of Owner and Commissioning Authority personnel time witnessing re-testing if the test failed due to failure to execute the relevant Prefunctional Checklist correctly; if the test failed for reasons that would not have been identified in the Prefunctional Checklist process, Contractor shall bear the cost of the second and subsequent re-tests.

E. Functional Test Procedures:

1) Some test procedures are included in Contract Documents; where Functional Test procedures are not included in Contract Documents, test procedures will be determined by the Commissioning Authority with input by and coordination with Contractor.

2) Examples of Functional Testing:

a. Test the dynamic function and operation of equipment and systems (rather than just components) using manual (direct observation) or monitoring methods under full operation (e.g., the chiller pump is tested interactively with the chiller functions to see if the pump ramps up and down to maintain the differential pressure setpoint).

b. Systems are tested under various modes, such as during low cooling or heating loads, high loads, component failures, unoccupied, varying outside air temperatures, fire alarm, power failure, etc.

01 9113 General Commissioning Requirements 7

c. Systems are run through all the HVAC control system’s sequences of operation and components are verified to be responding as the sequence's state.

d. Traditional air or water test and balancing (TAB) is not Functional Testing; spot checking of TAB by demonstration to the Commissioning Authority is Functional Testing.

F. Deferred Functional Tests: Some tests may need to be performed later, after substantial completion, due to partial occupancy, equipment, seasonal requirements, design or other site conditions; performance of these tests remains the Contractor's responsibility regardless of timing.

3.5. SENSOR AND ACTUATOR CALIBRATION

A. Calibrate all field-installed temperature, relative humidity, carbon monoxide, carbon dioxide, and pressure sensors and gauges, and all actuators (dampers and valves) on this piece of equipment shall be calibrated. Sensors installed in the unit at the factory with calibration certification provided need not be field calibrated.

B. Calibrate using the methods described below; alternate methods may be used, if approved by Commissioning Authority and Owner beforehand. See PART 2 for test instrument requirements. Record methods used on the relevant Prefunctional Checklist or other suitable forms, documenting initial, intermediate and final results.

C. All Sensors:

1) Verify that sensor location is appropriate and away from potential causes of erratic operation.

2) Verify that sensors with shielded cable are grounded only at one end.

3) For sensor pairs that are used to determine a temperature or pressure difference, for temperature make sure they are reading within 0.2 degree F of each other, and for pressure, within tolerance equal to 2 percent of the reading, of each other.

4) Tolerances for critical applications may be tighter.

D. Sensors Without Transmitters - Standard Application:

1) Make a reading with a calibrated test instrument within 6 inches of the site sensor.

2) Verify that the sensor reading, via the permanent thermostat, gauge or building automation system, is within the tolerances in the table below of the instrument-measured value.

3) If not, install offset, calibrate or replace sensor.

E. Sensors With Transmitters - Standard Application.

1) Disconnect sensor.

2) Connect a signal generator in place of sensor.

3) Connect ammeter in series between transmitter and building automation system control panel.

01 9113 General Commissioning Requirements 8

4) Using manufacturer’s resistance-temperature data, simulate minimum desired temperature.

5) Adjust transmitter potentiometer zero until 4 mA is read by the ammeter.

6) Repeat for the maximum temperature matching 20 mA to the potentiometer span or maximum and verify at the building automation system.

7) Record all values and recalibrate controller as necessary to comply with specified control ramps, reset schedules, proportional relationship, reset relationship and P/I reaction.

8) Reconnect sensor.

9) Make a reading with a calibrated test instrument within 6 inches of the site sensor.

10) Verify that the sensor reading, via the permanent thermostat, gauge or building automation system, is within the tolerances in the table below of the instrument-measured value.

11) If not, replace sensor and repeat.

12) For pressure sensors, perform a similar process with a suitable signal generator.

F. Sensor Tolerances for Standard Applications: Plus/minus the following maximums:

1) Watthour, Voltage, Amperage: 1 percent of design.

2) Pressure, Air, Water, Gas: 3 percent of design.

3) Air Temperatures (Outside Air, Space Air, Duct Air): 0.4 degrees F.

4) Relative Humidity: 4 percent of design.

5) Barometric Pressure: 0.1 inch of Hg.

6) Flow Rate, Air: 10 percent of design.

7) Flow Rate, Water: 4 percent of design.

8) AHU Wet Bulb and Dew Point: 2.0 degrees F.

G. Critical Applications: For some applications more rigorous calibration techniques may be required for selected sensors. Describe any such methods used on an attached sheet.

H. Valve/Damper Stroke Setup and Check:

1) For all valve/damper actuator positions checked, verify the actual position against the control system readout.

2) Set pump/fan to normal operating mode.

3) Command valve/damper closed; visually verify that valve/damper is closed and adjust output zero signal as required.

01 9113 General Commissioning Requirements 9

4) Command valve/damper to open; verify position is full open and adjust output signal as required.

5) Command valve/damper to a few intermediate positions.

6) If actual valve/damper position does not reasonably correspond, replace actuator or add pilot positioner (for pneumatics).

I. Isolation Valve or System Valve Leak Check: For valves not associated with coils.

1) With full pressure in the system, command valve closed.

2) Use an ultra-sonic flow meter to detect flow or leakage.

3.6. TEST PROCEDURES - GENERAL

A. Provide skilled technicians to execute starting of equipment and to execute the Functional Tests. Ensure that they are available and present during the agreed upon schedules and for sufficient duration to complete the necessary tests, adjustments and problem-solving.

B. Provide all necessary materials and system modifications required to produce the flows, pressures, temperatures, and conditions necessary to execute the test according to the specified conditions. At completion of the test, return all affected equipment and systems to their pre-test condition.

C. Sampling: Where Functional Testing of fewer than the total number of multiple identical or near-identical items is explicitly permitted, perform sampling as follows:

1) Identical Units: Defined as units with same application and sequence of operation; only minor size or capacity difference.

2) Sampling is not allowed for:

a. Major equipment.

b. Life-safety-critical equipment.

c. Prefunctional Checklist execution.

3) XX = the percent of the group of identical equipment to be included in each sample;

defined for specific type of equipment.

4) YY = the percent of the sample that if failed will require another sample to be tested;

defined for specific type of equipment.

5) Randomly test at least XX percent of each group of identical equipment, but not less than three units. This constitutes the "first sample."

6) If YY percent of the units in the first sample fail, test another XX percent of the remaining identical units.

7) If YY percent of the units in the second sample fail, test all remaining identical units.

8) If frequent failures occur, resulting in more troubleshooting than testing, the Commissioning Authority may stop the testing and require Contractor to perform and document a checkout of the remaining units prior to continuing testing.

01 9113 General Commissioning Requirements 10

D. Manual Testing: Use hand-held instruments, immediate control system readouts, or direct observation to verify performance (contrasted to analyzing monitored data taken over time to make the “observation”).

E. Simulating Conditions: Artificially create the necessary condition for the purpose of testing the response of a system; for example apply hot air to a space sensor using a hair dryer to see the response in a VAV box.

F. Simulating Signals: Disconnect the sensor and use a signal generator to send an amperage, resistance or pressure to the transducer and control system to simulate the sensor value.

G. Over-Writing Values: Change the sensor value known to the control system in the control system to see the response of the system; for example, change the outside air temperature value from 50 degrees F to 75 degrees F to verify economizer operation.

H. Indirect Indicators: Remote indicators of a response or condition, such as a reading from a control system screen reporting a damper to be 100 percent closed, are considered indirect indicators.

I. Monitoring: Record parameters (flow, current, status, pressure, etc.) of equipment operation using dataloggers or the trending capabilities of the relevant control systems; where monitoring of specific points is called for in Functional Test Procedures:

1) All points that are monitored by the relevant control system shall be trended by Contractor; at the Commissioning Authority’s request, Contractor shall trend up to 20 percent more points than specified at no extra charge.

2) Other points will be monitored by the Commissioning Authority using dataloggers.

3) At the option of the Commissioning Authority, some control system monitoring may be replaced with datalogger monitoring.

4) Provide hard copies of monitored data in columnar format with time down left column and at least 5 columns of point values on same page.

5) Graphical output is desirable and is required for all output if the system can produce it.

6) Monitoring may be used to augment manual testing.

3.7. OPERATION AND MAINTENANCE MANUALS

A. See Section 01 7800 - Closeout Submittals for additional requirements.

B. Submit manuals related to items that were commissioned to Commissioning Authority for review; make changes recommended by Commissioning Authority.

C. Commissioning Authority will add commissioning records to manuals after submission to Owner.
