This includes providing resolution for issues and providing details that cannot be or were not fully developed during design (such as scheduling, participation of various parties of this particular project, actual lines of reporting and approvals, coordination, etc.) Abbreviations The following are common abbreviations used in the specification and in the commissioning plan: 1.2. Scope A/E- Architect and Design Engineers FT- Functional Test BAS- Building Automation System GC- General Contractor (prime) BoD- Basis of Design MC- Division 15 Mechanical Contractor Cx- Commissioning O&M- Operation and Maintenance CxA- Commissioning Authority OPR- Owner s Project Requirements Cx Plan- document PM- Project Manager (of the Owner) CC- Controls Contractor (Building PT- Performance Test Automation System Contractor) CM- Construction Manager Subs Subcontractors (CC, EC, MC, TAB) EC- Division 16 Electrical Contractor TAB- Test and Balance Contractor Cx is a systematic process of ensuring that all building systems perform interactively according to the OPR and BoD. This is achieved by beginning in the design phase and documenting the OPR and continuing through construction, acceptance and the warranty period with actual verification of performance. The Cx process will encompass and coordinate the separate functions of system documentation, equipment start-up, control system calibration, testing and balancing, performance testing and training. Cx during the construction phase is intended to achieve the following specific objectives according to the Contract Documents: Verify that applicable equipment and systems are installed according to the manufacturer s recommendations and to industry accepted minimum standards and that they receive adequate operational checkout by installing Contractors. Verify and document proper and energy efficient performance of equipment and systems. Verify that O&M documentation left on site is complete. Verify that the Owner s operating personnel are adequately trained.

Coordination of Commissioning During Construction In general, the CxA coordinates the commissioning activities and reports to the GC and Owner. The CxA s responsibilities, along with all other contractors commissioning responsibilities are detailed in the specifications. The Specifications will take precedence over this Cx Plan. All members work together to fulfill their contracted responsibilities and meet the objectives of the Contract Documents Communication Protocols The following protocols will be used on this project. Issue For requests for information (RFI) or formal documentation requests: For minor or verbal information and clarifications: For notifying contractors of deficiencies: For scheduling functional tests: For scheduling commissioning meetings: Protocol Construction: The CxA goes through the GC. The CxA goes direct to the informed party. Construction: The CxA documents deficiencies through the GC, but may discuss deficiency issues with contractors prior to notifying the PE. The CxA may provide input for and do some coordination of testing, but does not do any scheduling. Construction: The CxA selects the date and schedules through the PE.

10 For making small changes in specified sequences of operations: Subcontractors disagreeing with requests or interpretations by the CxA shall: Page 9 of 17 The CxA may make small sequences of operations changes to improve efficiency or control or to correct deficiencies, through the responsible contractor, but shall document the change and provide all changes of specified sequences to the PE and A/E. Try and resolve with the CxA first. Then work through GC who will work with CxA directly or through the PE to resolve the situation. 4. Commissioning Process This section sequentially details the Cx process during construction by task or activity Overview The required commissioning activities are listed. A detailed description of each activity and assignment of responsibility is given. The commissioning process methodology contained in this chapter is based on the design-build organizational structure, as shown in Figure 4-2. Construction Phase 4.2. Cx Kick-off Meeting A Cx kick-off meeting is planned and conducted by the CxA near 30% construction progress. In attendance are the respective representatives of the GC, CxA, PM, A/E, MC, EC, CC and TAB. At the meeting, Cx parties are introduced and the Cx process reviewed, management and reporting lines determined. Also covered are the general list of each party s responsibilities, who is responsible to develop the start-up checklist for each piece of equipment and the proposed Cx schedule. The outcome of the meeting is increased understanding by all parties of the Cx process and their respective responsibilities. The meeting provides the CxA additional information needed to finalize the Cx Plan. Prior to or during this meeting, the GC shall provide all drawings and specifications and the construction schedule by trade to the CxA Final The CxA finalizes the Cx Plan using the information gathered from the kick-off meeting. The initial Cx schedule and timeline is also developed. The timeline is fine-tuned as construction progresses. In particular, prior to start-up of the primary equipment, the CxA meets with the GC and develops a detailed Cx schedule. The Cx plan is approved by the GC Site Observation

11 Page 10 of 17 The CxA makes periodic visits to the site, as necessary, to witness and observe equipment and system installations. The GC shall provide the CxA with completed construction checklists for installation verification Meetings The CxA attends selected planning and job site meetings in order to remain informed on construction progress and to update parties involved in Cx. The GC provides the CxA with information regarding substitutions, change orders and any Architect s Supplemental Instructions that may affect commissioned equipment, systems or the Cx schedule. The CxA may review construction meeting minutes, change orders and Architect s Supplemental Instructions for the same purpose. Later during construction, necessary meetings between various Cx Team members will be scheduled by the CxA through the GC as required Progress and Reporting Logs The CxA regularly communicates with all members of the Cx team, keeping them apprised of Cx progress and scheduling issues Special Submittals, Notifications and Clarifications The subs, GC or A/E notify the CxA of any new design intent or operating parameter changes, added control strategies and sequences of operation, or other change orders that may affect commissioned systems. The CC provides the CxA a full points list with details requested by the CxA. Prior to performing owner-contracted tests, the Subs provide the CxA full details of the procedures. As the phases of the test, adjust and balance are completed, the draft test, adjust and balance report is provided to the CxA with full explanations of approach, methods, results, data table legends, etc. The final test, adjust and balance report is provided to the CxA upon completion. These submittals to the CxA do not constitute compliance for O&M manual documentation. The CxA may request additional design narratives from the A/E and from the Subs depending on the clarity of the bid document information. The O&M Manuals are the responsibility of the contractor, though the CxA will review and approve them Start-up and Associated Documentation/Checklists Equipment Start-up Checklists are important to ensure the equipment and systems are hooked up and operational and that functional and performance testing may proceed without unnecessary delays. Each piece of equipment receives full Start-up checkout by the installing Contractor. No sampling strategies are allowed. In general, the start-up checklists for a given system must be successfully completed prior to formal functional and performance testing of that system.

12 Page 11 of 17 Start-up checklists are primarily static inspections and procedures to prepare the equipment or system for initial operation (e.g., oil levels OK, fan belt tension, labels affixed, gages in place, sensor calibration, etc.). However, some start-up checklist items entail simple testing of the function of a component, a piece of equipment or system (such as measuring the voltage imbalance on a three phase pump motor of a chiller system). The subs start-up checklists augment and are combined with the manufacturer s start-up checklist. Contractors typically already perform some, if not most or all, of the start-up checklist items the CxA will recommend. However, some contractors do not document in writing the execution of these checklist items. This project requires that the procedures be documented in writing by the installing technician. The CxA does not witness much of the start-up, except for testing of larger or more critical pieces of equipment and some spot-checking Start-up checklist The CxA assists the Cx team members responsible for start-up in developing detailed start-up checklists for all equipment. The parties responsible for each part of start-up and initial checkout are identified on the start-up checklists. The following procedures will be used for this project (the sub is responsible for the start-up checklist development): The CxA adapts and enhances, if necessary, the representative start-up checklists and procedures proposed by the subs, as necessary. The GC designates which trade or contractor is responsible to fill out the start-up checklists. The GC then transmits the start-up responsibilities to the associated Subs. The sub designated to develop the start-up checklist obtains manufacturer installation, startup and checkout data, including actual field checkout sheets used by the field technicians. The Sub identifies important instructional data and procedures (not covered in manufacturer field checkout sheets) from the manufacturer s start-up and checkout manuals and incorporates them into the start-up checklist, with a signature line to verify the procedure was performed. The Sub transmits the full start-up checklist to the CxA for review and approval. The CxA reviews and approves the procedures and the format for documenting start-up, noting any procedures that need to be added, and conveys to the Owner and GC. The GC then transmits the checklists to the Subs for their review and use. (The start-up checklist for a piece of equipment may go to more than one Sub, i.e. the MC and EC may have to work together to start-up certain pieces of equipment.) Execution of Checklists and Start-up Prior to start-up, the Subs and vendors schedule start-up and initial checkout with the GC and CxA. The start-up and initial checkout are directed and executed by the Sub or vendor. If

13 Page 12 of 17 necessary, the GC and CxA observe start-up procedures for each piece of primary equipment (unless there are multiple units, and a sampling strategy is used). For components of equipment (e.g. VAV boxes), the CxA may observe a sampling of the start-up procedures. To document the process of start-up and checkout, the site technician performing the line item task initials, dates, and checks off items/procedures on the equipment start-up checklists and manufacturer field checkout sheets, as they are completed. Only individuals having direct knowledge of a line item being completed shall check or initial the forms. The Subs and vendors execute the checklists and tests and submit a signed copy of the completed start-up checklists to the CxA. The CxA may review start-up checklists in progress, as necessary. On smaller equipment, the checklists (which all contain more than one trade s responsibility) may be passed around to the Subs to fill out Deficiencies and Non-conformance The Subs clearly list any outstanding items of the initial start-up checklists that were not completed successfully at the bottom of the form or on an attached sheet. The form and deficiencies are provided to the CxA within two days of test completion. The CxA works with the Subs and vendors to correct and retest deficiencies or uncompleted items, involving the GC and others as necessary. The installing Subs or vendors correct all areas that are deficient or incomplete according to the checklists and tests. The CxA recommends approval of the start-up and initial checkout of each system to the Owner and GC Testing, Adjusting and Balancing The TAB submits the outline of the test, adjust and balance plan and approach to the CxA and the CC prior to starting the test, adjust and balance. Included in the approach, is an explanation of the intended use of the building control system. The CxA reviews the plan and approach for understanding and coordination issues and may comment, but does not approve. The CC reviews the feasibility of using the building control system for assistance in test, adjust and balance work. The TAB submits written reports of discrepancies, contract interpretation requests and lists of completed tests to the CxA and GC. This facilitates quicker resolution of problems and will result in a more complete test, adjust and balance before functional testing begins. Testing, adjusting, and balancing work will not begin until the controls checkout and selective functional tests have been performed and approved by the CxA. After the testing, adjusting balancing report has been submitted, the CxA will approve air and water systems balancing by spot testing, by reviewing completed reports and by selected site observation. CxA will select, at random, 10% of TAB report for spot testing. CxA will schedule and observe spot testing. TAB shall provide personnel and equipment/instruments to perform tests. The TAB shall use the same equipment/instruments (by model and serial number) that

14 Page 13 of 17 were used when original data in report were collected. Any reading that deviates more than 10% from the design values will result in rejection of the final TAB report Controls Checkout Plan The CC develops and submits a written step-by-step plan to the CxA which describes the process they intend to follow in checking out the control system and the forms on which they will document the process. The CC shall also meet with the TAB prior to the start of test, adjust and balance plan to determine the capabilities of the control system for use in testing, adjusting and balancing. The CC shall provide the TAB with any necessary unique instruments for setting terminal unit boxes, etc. and instruct TAB in their use (handheld control system interface for use around the building during testing, adjusting and balancing, etc.). The CC shall also provide a technician qualified to operate the controls to assist the TAB. Controls checkout, calibrations, start-up and selected functional tests of the system shall be completed and approved by the CxA prior to testing, adjusting, and balancing. The controls contractor shall execute the tests and trend logs assigned to them and remain on site for executing mechanical system functional and performance tests Development of Functional Performance Test (FPT s) Procedures Overview FPT s are the dynamic tests of systems (rather than just components) 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). 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. The systems are run through all of the control system s sequences of operation and components are verified to be responding as the sequences state. The CxA develops the FPT procedures in a sequential written form, observes and documents the actual testing, which is usually performed by the CC Development Process Before test procedures are written, the GC provides a current list of change orders affecting equipment or systems, including an updated points list, control sequences and setpoints to the CxA. The CxA develops specific FPT procedures for each piece of equipment and system. Prior to execution, the CxA provides a copy of the primary equipment tests to the installing Sub (via the GC) who reviews the tests for feasibility, safety, warranty and equipment protection. Blank copies of the procedures are input into the O&M manuals for later use by operations staff.

15 Page 14 of 17 FPT s, and verification may be achieved by manual testing (persons manipulate the equipment and observe performance) or by monitoring the performance and analyzing the results using the control system s trend log capabilities or by stand-alone dataloggers (provided by the CC). The CxA follows the Specifications when given and uses judgment where needed to determine which method is most appropriate. According to the Specifications, not all pieces of identical equipment receive in-depth testing. The CxA reviews owner-contracted, factory or required owner acceptance tests and determines what further testing may be required to comply with the Specifications. Redundancy is minimized. The CxA reviews and approves documentation format of these tests prior to execution, but does not develop the procedures or document their execution, unless so requested by the Owner Execution of Functional Performance Testing Procedures Overview and Process The CxA will schedule FPT s through the GC and affected Subs. For any given system, prior to performing testing, the CxA waits until the start-up checklist has been submitted with the necessary signatures, confirming that the system is ready for functional testing. The CxA observes and documents the functional performance testing of all equipment and systems according to the Specifications and the Cx Plan. The Subs execute the tests. The control system is tested before it is used to verify performance of other components or systems. The air balancing and water balancing is completed and debugged before functional and performance testing of air-related or water-related equipment or systems. Testing proceeds from components to subsystems to systems and finally to interlocks and connections between systems Deficiencies and Retesting The CxA documents the results of the test. Corrections of minor deficiencies identified are made during the tests at the discretion of the CxA. The CxA records the results of the test on the procedure or test form. Deficiencies or non-conformance issues are noted and reported to the Owner and GC. Subs correct deficiencies, and then notify the CxA of the correction. The CxA will schedule retesting through the GC and affected subs. Decisions regarding deficiencies and corrections are made at as low a level as possible, preferably between the CxA and the Sub. For areas in dispute, final authority, besides the Owner s, resides with the A/E. The CxA recommends acceptance of each test to the GC. The GC gives final approval on each test Miscellaneous Management Protocols The following protocols will be used on this project. Issue For notifying contractors of deficiencies: Protocol The CxA documents deficiencies through the design-builder, but may discuss deficiency issues

16 For scheduling functional tests: For scheduling commissioning meetings: For making a request for significant changes: Page 15 of 17 with contractors prior to notifying the designbuilder. The CxA may provide input for testing, but does not do any scheduling. The design-builder selects the date and schedules through the CxA The CxA has no authority to issue change orders. Subcontractors disagreeing with requests or interpretations by the CxA shall: Try and resolve with the CxA first. Then work through the design-builder to resolve the situation. The design-builder has ultimate decision making authority. 5. Acceptance Phase 5.1. Functional Performance Tests (FPTs) The commissioning agency advises, witnesses and documents the results of the functional performance tests of all systems commissioned. The contractor operates the systems as advised by the commissioning authority so that FPTs, as documented in the commissioning plan, can be completed. The ATC and LC contractors and applicable Division 15 & 16 sub-contractors will participate, along with other relevant commissioning team members. The ATC and LC contractors may have to override normal control operation or parameters to simulate specific test conditions, and set up trend-logs to provide a record of system responses to test actions. FPTs should progress from individual items of equipment and subsystems, to complete systems, to interfaces between HVAC systems, and finally to interfaces between HVAC systems and non-hvac systems, depending on the scope of the commissioning plan. This test progression helps to isolate the cause of problems while confirming correct operation of smaller portions of the installation, before moving on to tests involving larger systems or interfaces between systems Correct Problems and Re-test If problems or incomplete work are discovered during functional performance tests, the responsible subcontractors must correct or complete the work, and have it re-tested with satisfactory results before proceeding to the next stage of commissioning, unless otherwise directed by design-builder. The commissioning agency will recommend stoping the process if numerous problems indicate that the installation is not ready for FPTs. The commissioning specification and the commissioning plan should clearly indicate the financial responsibilities in the event of failed or aborted FPTs Post-Acceptance Phase

17 Page 16 of 17 The commissioning process does not end until system issues are resolved to the satisfaction of the owner, and full documentation of the systems is provided. The following activities may occur after substantial completion Correct Problems and Re-test As with earlier tests, the contractor is responsible for correcting problems, and carrying out follow-up checks necessary to confirm correct operation. The commissioning agency is responsible for witnessing re-tests for satisfactory results. Contract documents should assign financial responsibilities for the costs associated with failed or aborted tests Final Commissioning Report The commissioning agency is responsible for preparing and submitting the final commissioning report to the owner and the design team. This report uses the final commissioning plan as its template. The report includes all system verification and start-up checklists, and all functional performance test checklists, completed with all test observations, problems encountered, corrective actions taken, and re-test results dated and signed by those carrying out and witnessing the tests. Where the checklists make reference to other test reports, copies of those reports must be appended. The final commissioning report should contain an executive summary addressing design intent conformance for all systems commissioned Summary Report A final summary report by the CA will be provided to the PM. The report shall include an executive summary, list of participants and roles, brief building description, overview of commissioning and testing scope and a general description of testing and verification methods. All outstanding non-compliance items will be specifically listed. Recommendations for improvement to equipment or operations, future actions, commissioning process changes, etc. will also be listed. Each non-compliance issue will be referenced to the specific functional test, inspection, trend log, etc. where the deficiency is documented. The functional performance and efficiency section for each piece of equipment will include a brief description of the verification method used (manual testing, BAS trend logs, data loggers, etc.) and include observations and conclusions from the testing. Appendices will contain acquired sequence documentation, logs, meeting minutes, progress reports, deficiency lists, site visit reports, findings, unresolved issues, communications, etc. System Verification Checklists and Functional Performance Tests (along with blanks for the operators) will be provided. 6. Schedule 6.1. General Issues The following sequential priorities are followed:

18 Page 17 of 17 Equipment is not temporarily started (for heating or cooling), until start-up checklist items and all manufacturer pre-start procedures are completed and moisture, dust and other environmental and building integrity issues have been addressed. The controls system and equipment it controls are not functionally tested until all points have been calibrated and controls checkout is completed. Testing, adjusting and balancing is not performed until the controls system has been sufficiently functionally tested. Testing, adjusting and balancing is not performed until the envelope is completely enclosed and ceiling complete, unless the return air is ducted. FPT s are not begun until after start-up checklists and testing, adjusting, and balancing is completed, for a given system (this does not preclude a phased approach) Project Schedule The commissioning functional performance testing is still yet to be determined.
