A. Section 220800 Commissioning of Plumbing

B. Section 230800 Commissioning of HVAC

C. Section 260800 Commissioning of Electrical

1.3 ABBREVIATIONS AND DEFINITIONS

A. BOD: Basis of Design. A document that records concepts, calculations, decisions, operational performance criteria and product selections used to meet the OPR and to satisfy applicable regulatory requirements, standards, and guidelines. The document includes both narrative descriptions and lists of specific items required to meet the Owner’s Project Requirements.

B. Commissioning Authority: The reviewing entity employed directly by the Owner to verify that the Owner’s Project Requirements are met, and to assist the Owner by providing quality improvement services.



C. Commissioning Issues Log: The primary document for recording and communicating issues identified through the commissioning process.

D. Design Professional: The design professional or professionals of record responsible for sealing the construction documents, permit applications and for consultations with the authority having jurisdiction at various stages of plan review and construction. They are referred to separately when they perform distinct functions with respect to commissioning, such as considering commissioning comments during formal review of product data and other submittals.

E. FPT: Functional Performance Testing, including testing of individual components, entire systems, and intersystem performance.

F. O&M: Operations and Maintenance.

G. OPR: Owner's Project Requirements. A document that details the functional requirements of a project and the expectations of how it will be used and operated. These include Project goals, measurable performance criteria, cost considerations, benchmarks, success criteria, and supporting information. The commissioning process verifies and documents whether the final built commissioned systems in the project meet the OPR.

H. PFC: Pre-Functional Checklists developed by Stephen Turner Inc. for completion by Trade Contractors.

I. Submittals: Documents required by the contract documents including product data and other formal submittals.

J. Systems, Subsystems, Equipment, and Components: Where these terms are used together or separately, they shall mean "as-built" systems, subsystems, equipment, and components.

K. Systems Checklists: Checklists developed and completed by Stephen Turner Inc.

L. TAB: Test, Adjust and Balance.

1.4 COMMISSIONING PROCESS

A. For this project, Stephen Turner Inc. is the commissioning authority contracted directly by the Owner to lead the commissioning process. The design team, construction manager, and contractors, along with the Owner (Project Manager, Users, and Operations), form the commissioning team.

B. The commissioning process, including Functional Performance Tests, is separate from and does not reduce or replace the requirements of the formal acceptance process by the Owner and Design Professional or the requirements of the authorities having jurisdiction. Stephen Turner Inc. will accept documented testing performed as part of the formal acceptance process that is witnessed by the Owner, Design Professional or the authorities having jurisdiction in order to avoid duplicate testing where possible.

C. Sampling 1. Generally, representative samples of the work will be periodically verified by

Stephen Turner Inc. as an indicator of the quality of the work.



2. This sampling method will be used as a quality check for equipment, piping, redline or record drawings, etc. The intent is that commissioning verification occurs when each aspect of commissioned work first begins, so that any resulting changes required are made after only a small portion of the work is put in place, not all of it.

D. Problem Solving 1. Stephen Turner Inc. will suggest solutions to issues but does not assume the

burden of responsibility to solve and correct issues that are found.

E. Communication During Construction Phase 1. Coordination of Trade Contractor participation in the commissioning team is

through the Construction Manager. Comments, observations, etc. resulting from commissioning activities will be recorded in the Commissioning Issues Log and relayed directly to the responsible party whenever possible, with copies to the Owner, Design Professional and Construction Manager, as applicable. This includes submittal comments, site observation reports, test reports, etc. This direct communication approach is intended to avoid delays from traditional remote paper exchanges, will encourage dialogue and discussion of options and alternatives, and generally maintain an atmosphere of cooperation and quality.

2. Stephen Turner Inc. is not responsible for design concept, design criteria, compliance with codes, design or general construction scheduling, cost estimating, or construction management.

3. Stephen Turner Inc. may assist with problem solving, non-conformance or deficiencies, but ultimately that responsibility resides with the construction manager.

4. The primary role of Stephen Turner Inc. is to develop and coordinate the execution of the commissioning plan including testing, to observe and document performance, and to document whether systems are functioning in accordance with the documented Owner’s Project Requirements.

5. Stephen Turner Inc. does not direct or redirect the Construction Manager or the Trade Contractors in their contracted work, and no communication shall be construed as such direction.

6. Stephen Turner Inc. is not authorized to: a. Release, revoke, alter or expand requirements of Contract Documents. b. Approve or accept any portion of the work. c. Perform any duties of the Construction Manager, its consultants, or its

contractors.

F. Response Times 1. Timeliness in delivering information or forming responses to Stephen Turner

Inc., and back, are essential to providing the built project to the Owner on time, as well as to implementing commissioning.

2. The following are guidelines established to meet this objective, and should be followed unless there are extenuating circumstances – in which case the delay shall be explained to each party in advance of the delay. Failure to avoid delays means that the delayed work product may not be incorporated into the commissioning reporting process, requiring a separate resolution process with the Owner without commissioning assistance.



a. Construction schedule by the Construction Manager incorporating separate activities for commissioning activities, as a minimum including pre-functional checklists, equipment start-ups, controls completion, TAB, and functional performance testing. 1) Within 10 business days after award of Division 22, 23 and 26 work. 2) Appendix C shows a typical component-level commissioning

schedule by Stephen Turner Inc. with the dependencies between construction activities and commissioning activities.

b. Project-specific comments from Stephen Turner Inc. on how commissioning activities and dates are incorporated into the schedule: 1) Within 10 business days after receiving component schedule for

Division 22, 23 and 26 work and updates throughout project. c. Submittal comments by Stephen Turner Inc.:

1) 7 business days from date of receipt by Stephen Turner Inc. for typical product submittals; 15 business days for Controls, TAB, energy recovery equipment, and other selected complex submittal packages. Stephen Turner Inc. will identify other selected complex submittal packages in advance if provided with the submittal register.

2) For this paragraph’s purposes, “receive” means electronic or hard copy in the hands of Stephen Turner Inc.

d. Approved submittals to Stephen Turner Inc.: 1) Within 5 business days of receipt by construction manager.

e. Commissioning checklists by Stephen Turner Inc. to Construction Manager: 1) 10 business days before scheduled delivery of commissioned

equipment, provided that the schedule and the approved submittals have been provided to Stephen Turner Inc. 20 business days in advance.

f. Delivery of draft O&M manuals for Stephen Turner Inc. to review: 1) 30 business days after approved submittals.

g. Delivery of final O&M manuals and training materials to Stephen Turner Inc.: 1) 10 business days prior to each scheduled owner training session.

h. Delivery of record drawings marked to as-built conditions to Stephen Turner Inc.: 1) Prior to each scheduled training session.

i. Delivery of final as-built drawings to Stephen Turner Inc.: 1) Within 20 business days of start of warranty period(s).

j. Commissioning Issues Log entries by Stephen Turner Inc.: 1) Within 5 business days after observation.

k. Response by Construction Manager and Trade Contractor to commissioning Issues Log entries and field comments: 1) 5 business days after receipt of Issues Log where other parties are

not involved, or at the next commissioning meeting.



l. Delivery of functional performance testing procedures by Stephen Turner Inc. to Construction Manager: 1) 20 business days before scheduled testing provided that schedule

and draft O&M manuals have been provided to Stephen Turner Inc. at least 40 business days in advance of scheduled testing.

1.5 CONSTRUCTION MANAGER AND TRADE CONTRACTOR REQUIREMENTS

5. Upon acceptance, the Contractor and/or manufacturer shall replace or repair all identical items, at their expense and extend the warranty accordingly, if the original equipment warranty had begun. The replacement/repair work shall proceed with reasonable speed beginning within one week from when parts can be obtained.

6. For any functional performance testing issue identified that is not related to any issue identified on a pre-functional checklist or to a start-up fault, Stephen Turner Inc. will direct the retesting of the equipment once after the Construction Manager indicates the issue has been resolved. If the issue is still not resolved, Stephen Turner Inc. shall determine with the Owner how Stephen Turner Inc.’s cost for subsequent retesting will be borne.

F. Any required retesting shall not be considered a justified reason for a claim of delay or for a time extension by the Contractor.

G. Every effort will be made to expedite the testing process and minimize unnecessary delays, while not compromising the integrity of the testing procedures. As tests progress and an issue is identified, Stephen Turner Inc. will discuss the issue with the appropriate Trade Contractor who is performing the test to determine how to proceed. 1. Corrections of minor issues identified may be made during testing at the

discretion of Stephen Turner Inc. In such cases the issue and resolution will be documented on the test procedure form.

2. Major issues shall be corrected after the completion of testing. In such cases the issue and the Construction Manager and Trade Contractors proposed resolution will be documented on the test procedure form. Upon re-testing, the actual resolution will be documented.

H. Seasonal Commissioning Tests 1. Portions of the final commissioning test procedures including but not limited to

FPTs will be seasonally dependent (e.g., cooling system needs to be tested in late spring, summer, or early fall) and will need to be performed at a different time of year than the rest of the final commissioning testing.

If not specified on the drawings, get this information from the design engineer. Using a manometer and a squeeze bulb, slowly apply pressure to the switch sensing input until the threshold pressure is achieved. Verify that the switch activates. Release the pressure and verify that the switch remains activated (manual reset). Verify that the fan will not start in automatic or manual modes, either through the BAS, motor starter, or VFD as applicable. Press the manual reset and verify that the equipment will re-start. This portion of the test will be considered successful if the high static switch shuts down the fan unconditionally, and cannot be bypassed by any manual controls. Test 2: Low Temperature (Freeze Stat). Lower the temperature of the freeze stat sensing element. Verify that the switch activates. Raise the element temperature and verify that the switch remains activated (manual reset). Verify that isolation and outdoor air dampers close, that preheat valve opens, coil heats up, and that the fan will not start in automatic or manual modes, either through the BAS, motor starter, or VFD as applicable. Press the manual reset and verify that the equipment will re-start. This portion of the test will be considered successful if the freeze stat shuts down the fan unconditionally, heating coil temperature rises, and the fan cannot be bypassed by any manual controls. Test 3: AHU Fire Alarm Shutdown. Disconnect one end of the wire at the duct detector or fire alarm relay that is intended to shutdown the AHU. Verify that the fan will not start in automatic or manual modes, either through the BAS, motor starter, or VFD as applicable. Replace the wire and verify that the equipment will re-start. This portion of the test will be considered successful if the control circuit as wired shuts down the fan unconditionally, and cannot be bypassed by any manual controls. NOTE: this is not a fire alarm test, this only tests that the interface method used will shut down the fan unconditionally. When finished, return all overridden points, modes and sequences to their original state.

SUPPLY FAN VFD “RAMP-UP” AND “RAMP-DOWN”

PROCEDURE Begin the test with the VFD driven motor in the off position. With the fan in manual control, cause a step change from 0 to 50% commanded output. Verify that the VFD “ramp up” settings cause the motor to slowly increase in speed, and do not cause a abrupt change in speed. Cause a step change from 50 to 25% commanded output. Verify that the VFD “ramp down” settings cause the motor to slowly decrease in speed, and do not cause a abrupt change in speed. Once the test is completed, return all overridden points, modes and sequences to their original state. This portion of the test will be considered successful if the motor speed changes gradually after a step change output from the control system, indicating the “ramp-up” and “ramp-down” controls have been set in the VFD. 1.1

SUPPLY FAN STATIC PRESSURE CONTROL TEST



PROCEDURE Complete the high static pressure safety and VFD “Ramp-Up” and “Ramp-Down” tests before beginning this test. Set up trends for the supply air static pressure, setpoint, and VFD percentage. Begin the test with the fan at 0% capacity. With the duct static setpoint at 1.0 in. w.c., start the fan. Observe the VFD and motor to see if the control action is smooth and does not hunt. Allow sufficient time for the control system to stabilize, approximately 2 or 3 minutes maximum. Read the static pressure and verify that the setpoint was achieved. Decrease the static pressure setpoint by 0.5 in. w.c. and observe the control system reaction to the step change. Return all overridden points, modes and sequences to their original state. This portion of the test will be considered successful if the controls are stable and the duct static pressure controls achieve their setpoint.

AIR-SIDE ECONOMIZER CONTROL TEST

PROCEDURE High static pressure and freeze protection shutdown safety controls must be verified prior to this test, to avoid equipment damage during the test. For VAV system, open VAV boxes to permit unrestricted flow of the supply fan. The relationship between the outside air temperature, return air temperature, and mixed air temperature setpoint must be appropriate for utilizing the outdoor air for cooling purposes. In general, the OAT should be 55°F or less in order to conduct this test, and colder is better. In general, this test can be conducted if the OAT meets these requirements: OAT below RAT, OAT above freezing. If the OAT is not in the proper range, a complete test of the mixed air system will require a subsequent visit when the conditions are appropriate (seasonal test). Control the supply fan capacity for VAV air handlers manually during this test. Set up trends for OA, MA, and RA temperatures; OA cfm and setpoint; and OA and RA damper positions.



Test 1: Override the outside air temperature value to a point just above the lower limit of the economizer enable threshold value (temperature or enthalpy as applicable). When the threshold value is crossed, the control should respond by entering and leaving the economizer mode. When entering the economizer mode, observe the dampers begin to modulate to maintain mixed air temperature setpoint. When leaving the economizer mode, observe the dampers revert to minimum outside air position. This portion of the test will be considered successful if the system enters and leaves the economizer mode according to outside air temperatures at the specified thresholds, and maintains the minimum ventilation rate when the economizer is disabled. Test 2: If there is an economizer “enable” or “lockout” temperature or enthalpy, temporarily manipulate this point as required to keep it from interfering with the test (e.g. enable the economizer without regard to OAT or enthalpy). Based on (OAT) and (RAT), determine a reasonable mixed air setpoint that will set the controls into motion. Observe the mixing dampers to see if the control action is smooth and does not hunt. Allow sufficient time for the control system to stabilize, approximately 2 or 3 minutes maximum. Read the mixed air temperature and verify that the setpoint was achieved. Select a different mixed air temperature setpoint, preferably at least 10 degrees different than the original setpoint, and observe the control system reaction to the step change. Return all overridden points, modes and sequences to their original state. This portion of the test will be considered successful if the controls are stable and the mixed air controls achieve their setpoint.

RESULTS

SUPPLY AIR TEMPERATURE CONTROL TEST

PROCEDURE High static pressure and freeze protection shutdown safety controls must be verified prior to this test, to avoid equipment damage during the test. For VAV system, open VAV boxes to permit unrestricted flow of the supply fan. Temporarily disable the Air-Side Economizer Control operation before beginning this test.

Read the SA temperature and verify that the setpoint was achieved. Gradually increase the SA fan capacity to 100 % and observe the control system reaction to the step change. This portion of the test will be considered successful if the controls are stable and the SAT controls achieve their setpoint. Test 2: Temporarily disable the CW cooling controls. Start the SA fan, and gradually increase the speed until 50 % capacity is reached. Adjust the SA cooling temperature setpoint to 55°F and be sure it is lower than the SA temperature at this point. Release the CW controls. Observe the CW valve to see if the control action is smooth and does not hunt. Allow sufficient time for the control system to stabilize, approximately 2 or 3 minutes maximum. Read the SA temperature and verify that the setpoint was achieved. Gradually increase the SA fan capacity to 100 % and observe the control system reaction to the step change. Return all overridden points, modes, and sequences to their original state.

SOLAR THERMAL SYSTEM INCLUDES A DRAIN-BACK SYSTEM TO PROVIDE FOR FREEZEPROTECTION AND HIGH-LIMIT PROTECTION. SOLAR COLLECTORS SHALL BE INSTALLED TOALLOW FOR EMPTYING BY GRAVITY WHEN THE SYSTEM PUMP (CP-1) IS NOT OPERATING.

ALL CONTROL WIRING, SENSORS, RELAYS, CONDUITS,CURRENT SENSORS, PROGRAMMING, BMS INTEGRATION, GRAPHIC DISPLAYS AND POINTMAPPING SHALL BE PROVIDED BY DIVISION 23 (ATC CONTRACTOR). REFER TO HVACCONTROL DRAWINGS FOR FURTHER INFORMATION AND REQUIREMENTS.

SOLAR PUMP ON: SOLAR PUMP (CP-1) TURN ON WHEN THE TEMPERATURE DIFFERENCEBETWEEN THE SENSOR ON THE SOLAR COLLECTOR LOOP (T1) AND THE SENSORS INTHE SOLAR STORAGE TANKS (T2 & T3) EXCEEDS THE DELTA-T TEMPERATURE

DIFFERENCE OF 25 DEGREES F.

SOLAR PUMP OFF: SOLAR PUMP (CP-1) TURN OFF WHEN THE TEMPERATUREDIFFERENCE DECREASES AND FALLS BELOW 4˚ F.

SOLAR STORAGE TANK HIGH LIMIT : WHEN THE TEMPERATURE (T2 & T3) IN THE STORAGETANK EXCEEDS THE HI- LIMIT SETTING OF 180 DEGREES F, THE SOLAR PUMP (CP-1) RELAYWILL BE TURNED OFF WITHOUT DELAY REGARDLESS OF THE STATUS OF THETEMPERATURE DIFFERENCE THAT EXISTS BETWEEN THE SOLAR STORAGE TANK ANDTHE SOLAR COLLECTORS. WHEN THE STORAGE TANK TEMPERATURE FALLS 4˚ F BELOW

THE SETTING IN THE HI-LIMIT, THE CONTROLLER WILL THEN RESUME NORMALOPERATION.

SOLAR MINIMUM OPERATING TEMPERATURE : THE CIRCULATION PUMPS WILL BE

DEACTIVATED ANYTIME THE SOLAR COLLECTOR SENSOR (T1) IS BELOW 50 DEGREES F.NORMAL CONTROL OPERATION WILL NOT RESUME UNTIL THE COLLECTOR TEMPERATURERETURNS TO 70 DEGREES F. OR ABOVE.

HIGH LIMIT CONTROL: WHEN THE TEMPERATURE IN THE STORAGE TANKS EXCEEDS THEHI-LIMIT SETTING OF 180 DEGREES F, THE SOLAR PUMP RELAY WILL BE TURNED OFFWITHOUT DELAY REGARDLESS OF THE STATUS OF THE TEMPERATURE DIFFERENCE THAT

EXISTS BETWEEN THE SOLAR TANK AND THE SOLAR COLLECTORS. WHEN THE TANKTEMPERATURE IS LOWERED TO 175 DEGREES F. THE CONTROLLER WILL THEN RESUMENORMAL OPERATION.

IF TANK TEMPERATURE FALL TO 130 DEGREES F, ELECTRIC HEATING ELEMENT IN TANK SHALLBE ACTIVATED AND LOW WATER TEMPERATURE ALARM SHALL BE SENT TO BMS OPERATOR.

ALL TEMPERATURE SENSORS SHALL BE IMMERSION TYPE. TEMPERATURE SENSORS SHALL BEFURNISHED AND INSTALLED BY DIVISION 23. DIVISION 22 SHALL COORDINATE WITH DIVISION 23AND PROVIDE ALL NECESSARY PIPE AND TANK FITTINGS TO ACCEPT TEMPERATURE SENSORS.
