Pierce, FL. 34946 #20061 Executive Summary 06-12-2020 Scope of the Commissioning Program OCI Engineering was hired by Saint Lucie County, to provide commissioning services. The intent of the commissioning program was to help ensure that all commissioned systems were designed, installed and tested in accordance with the contract documents and the owner's requirements, and that all systems were fully functional when turned over to the owner by the contractor. Also, the program was intended to help ensure that the owner's maintenance personnel were fully trained in the operation and maintenance of the systems at completion of the project. The general contractor and all mechanical, electrical, controls and T&B subcontractors were members of the commissioning team and participated in the commissioning process. Commissioning activities for the project began March-09-2020 when the commissioning specifications and a commissioning plan were prepared for incorporation into the construction documents. Field visits were made to verify that the installation was in accordance with the plans and specifications and to hold commissioning meetings. Pre-commissioning check lists were prepared by OCI and completed by the contractors prior to the start of functional performance testing on June-08-2020. Commissioning of the mechanical systems was essentially finished on June-08-2020 with the punch list items addressed. OCI prepared a commissioning report of systems for the owner. Systems Commissioning was provided for one new dedicated AAON outside air unit, 3 existing EF's, new ductwork, and the updated building automation system. Orlando -Ft.

Orlando Avenue, Suite 100,Maitland,FL 32751 Phone: 407-332-5110 Fax: 407-332-7704 www.oc1associates.com Commissioning Methodology On this project, the commissioning process started when OCI developed pre-commissioning checklists for each piece of equipment which were then completed by the responsible contractor during startup. In many cases the checklists served as the startup forms. Once completed, the forms were spot checked against the installed equipment for accuracy. The check lists were intended to help the contractor document his startup activities and to bring some rigor and methodology to the startup process. All checklists were signed by the subcontractor's field personnel. Once the checklists were complete, the functional performance testing started using forms and procedures developed specifically for the project based on the engineer's drawings, sequences of operation and the approved control shop drawings and submittals. The equipment and controls were checked for full and proper operation. The actual test procedures and results can be found on the completed forms in the body of the report. Functional performance testing was carried out by OCI in conjunction with the responsible sub-contractors. The test and balance report was validated through random sampling of the readings in the final test and balance report. After the completion of the functional testing, the owner's operating staff was trained in the proper operation and maintenance of all systems related to this project. A random sampling of the calibration of control system analog inputs was conducted during the functional performance testing. All temperature sensors were calibrated. All thermostat control ranges and the high and low limit settings specified by the owner were programmed. Commissioning Results In general, the commissioning of the new air conditioning and heating systems, has resulted in systems that are fully functional in accordance with the contract documents (see resolution in daily log attached). The mechanical and controls contractors have corrected the deficiencies uncovered during commissioning process. Outstanding Issues At the completion of the functional testing program on June-08-2020 with exception as noted in the final FPT and daily log, all the systems were operating as specified and in accordance with the intent of the drawings and specifications.

This person shall be completely familiar with the work performed for this contract at all levels of detail of his trade and with coordination to other trades. Participate: Attend commissioning events, provide technical expertise or knowledge, equipment, measurements and observation needed or requested by the commissioning authority or owner. Provide follow-up analysis, equipment data, design data, or other trade or professional service needed in response to commissioning events. Verify: To positively determine that the measured or observed quantity satisfies all required criteria. Simply performing the test, measurement or observation does not constitute"verification". The test result must also pass all contract criteria. Tests, which fail, must be repeated at no additional cost to the owner after repairs or adjustments are made, until full verification is achieved. 1 1.2 Purpose of the Commissioning Plan The purpose of the construction phase commissioning plan is: To provide direction for team members participating in the commissioning process during construction, particularly 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 project, actual lines of reporting and approvals, coordination, etc. This plan does not provide a detailed explanation of required testing procedures. The detailed testing requirements and procedures are found in the specifications sections 230800. 1.3 Commissioning Scope Commissioning is a systematic process of achieving, verifying and documenting that the performance of the facility and its various systems meets the design intent and functional and operational needs of the owner and occupants. This includes the specific training of the facility personnel involved in the operation and maintenance of the building's equipment and facilities. There are numerous checks for each stage of the building commissioning process which ensures that set procedures are followed. This approach to constructing a building, along with the necessary training of facility personnel, serves as a thorough quality assurance program for building construction, and the building construction industry. Commissioning during the construction of this project is intended to achieve the following specific objectives: • Ensure that equipment and systems being commissioned are installed properly and receive adequate operational checkout by installing contractors. • Verify and document proper performance of equipment and systems. • Ensure that O&M documentation is complete. • Ensure that the owner's operating personnel are adequately trained. 2 1.4 Commissioning Flow Chart—For Fundamental Commissioning Requirements The following chart illustrates the overall status of the commissioning process for the project.

Issue Protocol For requests for The CxP goes first to the PM and the GC. information (RFI) or formal documentation requests: For minor or verbal The CxP goes directly to the informed party. information and clarification: For notifying contractors of The CxP documents deficiencies through the PM, but may discuss deficiencies: deficiency issues with contractors prior to notifying the PM. For scheduling functional The CxP works with the PM and GC to develop schedules. tests or training: For scheduling The CxP selects the date and schedules through the GC. commissioning meetings: For making a request for The CxP has no authority to issue change orders. significant changes: For making small changes The CxP may make small sequences of operations changes to in specified sequences of improve efficiency or control or to correct deficiencies, through the operations: responsible contractor, but shall review the change with the A/E, document the change and provide all changes of specified sequences to the PM and A/E. Subcontractors disagreeing Try and resolve with the CxP first. Then work through GC who will with requests or work with CxP directly or through the PM to resolve the situation. interpretations by the CxP shall: 5.3 Submittals and Documentation The CxP provides all subs responsible for commissioned equipment with commissioning documentation requirements for their respective equipment and systems. This data request typically coincides with the normal A/E submittal process. At minimum, this equipment data includes installation and start-up procedures, approved shop drawings, O&M data, performance data and control drawings. 5.4 Special Submittals, Notifications and Clarifications The subs, GC or A/E notify the CxP of any new design intent or operating parameter changes, added control strategies and sequences of operation, or other change order that may affect commissioned systems. The controls contractor provides the CxP a full points list with details requested by the CxP. Thirty (30) days prior to performing any required tests, cleaning or 12 flushing the subs provide the CxP full details of the procedures. As the phases of the TAB are completed, the draft TAB report is provided to the CxP with full explanations of approach, methods, results, data table legends, etc. The final TAB report is provided to the CxP upon completion. These submittals to the CxP do not constitute compliance for submittals for the O&M manuals. The CxP may request additional design narrative from the A/E and from the controls contractor depending on how complete the documentation was which was provided with the bid documents. The CxP may submit written RFIs to contractors through the PM, or address them directly for clarifications, as needed. 5.5 Pre-functional Checklists The word pre-functional refers to before functional testing. Pre-functional checklists (PC) are important to ensure that the equipment and systems are hooked up and operational and that functional performance testing may proceed without unnecessary delays. Each piece of equipment receives full pre-functional checkout by the contractor. No sampling strategies are used. In general, the pre-functional testing for a given system, must be successfully completed prior to formal functional performance testing of equipment or sub-systems of the given system. Pre-functional checklists are primarily static inspections and procedures to prepare the equipment or system for initial operation (e.g., oil levels checked, fan belt tension, labels affixed, gauges in place, sensor calibration, etc.). However, some pre-functional 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). Pre-functional checklists augment and are combined with the manufacturer's start-up checklist. Contractors typically already perform some, if not all, of the pre-functional checklist items the commissioning authority will recommend. However, few contractors document in writing the execution of these checklist items. This project requires that the procedures be documented in writing by the installing technician. The CxP does not witness all the pre-functional checklist verification, except for testing of larger or more critical pieces of equipment and some spot- checking. 5.6 Start-up The CxP assists the commissioning team members responsible for start-up in developing detailed start-up plans for all equipment. All start-up plans are to be approved by the CxP. Four weeks prior to start-up, the subs and vendors schedule start-up and initial checkout with the PM, GC and CxP. The start-up and initial checkout are directed and executed by the sub or vendor. The CxP, and PM if necessary, observe, at minimum, the procedures for each piece of primary equipment, unless there are multiple units, when a sampling strategy is used. For components of equipment, (e.g., VAV boxes), the CxP observes a sampling of the pre-functional and start-up procedures. To document the process of start-up and checkout, the site technician performing the line item task initials and dates each paragraph of procedures in the "start-up plan" and checks off items on the pre-functional 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 and pre-functional tests and checklists to the CxP. The CxP may review pre- 13 functional checklists in progress, as necessary. The subs clearly list any outstanding items of the initial start-up and pre-functional procedures that were not completed successfully at the bottom of the procedures form or on an attached sheet. The procedures form and deficiencies are provided to the CxP within two days of test completion. The CxP works with the subs and vendors to correct and retest deficiencies or uncompleted items, involving the PM and others as necessary. The installing subs or vendors correct all areas that are deficient or incomplete according to the checklists and tests. 5.7 TAB Plan The TAB contractor submits the outline of the TAB plan and approach to the CxP and the controls contractor eight weeks prior to starting the TAB. Included in the approach, is an explanation of the intended use of the building control system. The CxP reviews the plan and approach for understanding and coordination issues and may comment but does not approve changes. The controls contractor reviews the feasibility of using the building control system for assistance in the TAB work. The TAB submits weekly written reports of discrepancies, contract interpretation requests and lists of completed tests to the CxP and PM. This facilitates quicker resolution of problems and will result in a more complete TAB before functional testing begins. TAB work will not begin until the control system has been pre-functionally tested and selective functional tests have been performed and approved by the CxP. 5.8 Controls Check Out Plan The controls contractor develops and submits a written step-by-step plan to the CxP, 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 controls contractor will also meet with the TAB contractor prior to the start of TAB and review the TAB plan to determine the capabilities of the control system for use in TAB. The controls contractor will provide the TAB with any necessary unique instruments for setting terminal unit boxes and instruct TAB in their use (hand-held control system interface for use around the building during TAB, etc.). The controls contractor shall also provide a technician qualified to operate the controls to assist the TAB contractor in performing TAB. All CxP required controls pre-functional checklists, calibrations, start-up and selected functional tests of the system shall be completed and approved by the CxP prior to TAB. The controls contractor shall execute the tests and trend logs assigned to them and remain on site for assistance for mechanical system functional tests. 5.9 Development of Functional Test and Verification Procedures 5.9.1 Overview Functional testing is the dynamic testing 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 set point). 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 the control system's sequences of operation and components are verified to be responding as the sequences state. The commissioning authority develops the functional test procedures in a sequential written form, coordinates, oversees and documents the actual testing, which is usually performed by the installing contractor or vendor. 14 5.9.2 Scope of Testing A detailed description of the functional and pre-functional testing procedures and process will be developed for this project by the CxP for each piece of commissioned equipment. 5.9.3 Development Process Before test procedures are written, the CxP obtains all requested documentation and a current list of change orders affecting equipment or systems, including an updated points list, control sequences and set points. The CxP develops specific test procedures to verify proper operation of each piece of equipment and system. The CxP obtains clarification, as needed, from contractors and the A/E regarding sequences and operation to develop these tests. Prior to execution, the CxP 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. Functional testing 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 data loggers. The CxP uses judgment where needed to determine which method is most appropriate. 5.10 Execution of Functional Testing Procedures 5.10.1 Overview and Process The CxP schedules functional tests through the PM, GC and affected subs. For any given system, prior to performing functional testing, the CxP waits until the pre-functional checklist has been submitted with the necessary signatures, confirming that the system is ready for functional testing. The CxP oversees, witnesses and documents the functional 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 before functional 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. 5.10.2 Deficiencies and Retesting The CxP documents the results of the test. Corrections of minor deficiencies identified are made during the tests at the discretion of the CxP. The CxP records the results of the test on the procedure or test form. Deficiencies or non-conformance issues are noted and reported to the PM on the Commissioning Corrective Action Report(Daily Log). Subs correct deficiencies, notify the CxP and return the form certifying correction. The CxP schedules retesting through the PM. Decisions regarding deficiencies and corrections are made at as low a level as possible, preferably between CxP or PM and the sub. For areas in dispute, final authority, besides the owner's, resides with the A/E. The CxP recommends acceptance of each test to the PM. The PM gives final approval on each test. 15 5.11 Operating and Maintenance Manuals The CxP reviews the O&M manuals and documentation for systems that were commissioned to verify compliance with the specifications. The CxP recommends approval and acceptance of these sections of the O&M manuals to the PM. The CxP also reviews each equipment warranty and verifies that all requirements to keep the warranty valid are clearly stated. Initial preparation shall be the responsibility of the HVAC and electrical trade representative as per contract bid document. 5.12 Training of Owner's Personnel The owner's maintenance personnel shall be given comprehensive training in the understanding of the systems and the operation and maintenance of each major piece of equipment. The CxP, in cooperation with the contractor, schedules the training, which shall start with classroom sessions followed by hands on training on each piece of equipment. Hands on training shall include start- up, operation in all modes possible, shut-down and any emergency procedures. The contractor or his representative, shall conduct and video tape all sessions and shall add to each session any special information relating to the details of installation of the equipment as it might impact the operation and maintenance. 5.12.1 Overall Plan After reviewing the specifications, and after interviewing facility staff, if necessary, the owner and CxP fill out a table listing all the equipment for which training or orientation will be provided listing, among other things, the type and number of trainees, rigor of training desired by the owner, the primary responsible subcontractor, the trainer's company and columns for tracking training agendas. The commissioning authority provides this form to the contractor for reference. The contractor will prepare a training agenda describing the subjects covered, duration of each subject and the methods that will be used in the training, along with the name and qualifications of the trainer(s)for submission to the owner and CxP. The owner and CxP review the agenda; make comments; approve the training subject to the comments; and submit back to the contractor. The contractor provides the approved agenda to the trainer to use during the training. The trainer provides a copy of the agenda to each trainee. 5.13 Warranty Period During the warranty period, seasonal testing and other deferred testing required is completed according to the specifications. The CxP coordinates this activity. Tests are executed, and deficiencies corrected by the appropriate subs, witnessed by facilities staff and the CxP. Any final adjustments to the O&M manuals and record drawings due to the testing are made. In addition, the CxP will return to the project approximately 10 months into the 12-month warranty period. During this visit(s)the CxP will review with facility staff the current building operation and the condition of outstanding issues related to the original and seasonal commissioning. The CxP will also interview facility staff and identify problems or concerns they have operating the building as originally intended. 16 The CxP will make suggestions for improvements and for recording these changes in the O&M manuals. The CxP will identify areas that may come under warranty or under the original construction contract. The CxP will also assist facility staff in developing reports and documents and requests for services to remedy outstanding problems. 5.14 Final Commissioning Report A final summary report by the CxP 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. For each piece of commissioned equipment, the report should contain the disposition of the commissioning authority regarding the adequacy of the equipment, documentation and training meeting the contract documents. All outstanding non-compliance items shall be specifically listed. Each non-compliance issue shall 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 shall 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. The final commissioning report shall be submitted. The report shall contain as a minimum the following information: • Cover sheet with following information: • Date • Project and address • Architect • Engineer • General contractor • SCA (name, address, e-mail, fax & phone number) • Final updated commissioning plan • Name, address, phone, fax, e-mail for commissioning team members • Completed copies of all commissioning forms • Copies of Cx related RFI's, meeting minutes, contractor certification, reports, and code authority inspections. • Copies of inspection and construction observation reports • Copy of equipment and system certification forms with listing of equipment and systems commissioned. • Copies of completed component test forms 17 5.15 Schedule The initial commissioning schedule is summarized in the table below.

Cartier, P.E. Engineer's review is for general conformance with the design concept and contract documents.Markings or comments shall not be construed as relieving the Contractor from compliance with the project plans and specifications, nor departures therefrom. The Contractor remains responsible for details and accuracy, compliance with the Contract Documents and intent,for confirming and correcting all quantities and dimensions,for selecting appropriate fabrication processes,for techniques of assembly,and for performance of work in a safe manner. OVERALL DISPOSITION: Revise and Resubmit 1. Verify the recorded values for AHU-1. The summation of the outside air (1,852 CFM) and return air (4,665 CFM) exceed the supply air from the unit (total of outside and return is 6,517 CFM, recorded supply is 5,341 CFM). The summation of the return air from the AHU- 1 table is 2,808 CFM, which is not consistent with the value recorded in the AHU-1 data sheet (4,665 CFM). 2. It is noted that the final total supply air for RTU-1 is considerably lower than design (73%). 3. There is a difference of 356 CFM between the recorded RTU-2 supply air (1,986 CFM) and return air(1,630 CFM). This implies that the outside air damper on RTU-2 is not completely closed. Ensure the outside air damper on RTU-2 is completely closed and sealed and re- measure to ensure the supply and return airflow values are the essentially the same. 4. It appears exhaust fans EF-1, EF-2 and EF-3 have not been rebalanced to their respective new airflows as required by sheet M1.1, Plan Reference Notes 14, 13 and 15 respectively. Rebalance exhaust fans to values indicated, record and re-submit for review. 5. The Outside Air Unit test data is missing the entering and leaving dry bulb and wet bulb air temperatures across the unit heat pipe coils. Measure and record these values and include in the test report for evaluation. Refer to sheet M4.1, Grade Mounted Package 100% Outside Air Unit Schedule for indicated values across the pre-cooling and reheat coils. 6. Confirm the 52 degree off-coil temperature indicated in the Outside Air Unit report form is the temperature leaving the DX cooling coil prior to entering the heat pipe reheat coil. 7. Measure and record the total unit amp draw and voltage at design conditions. It appears the recorded values for amps and voltage are for the evaporator fan only. Refer to sheet M4.1, Grade Mounted Package 100% Outside Air Unit Schedule for unit design MCA value. Shop Drawing Review Comments Page 2 of 2 8. Rebalance total airflow from the Outside Air Unit to within 10% of the total design (1,540 CFM maximum) as opposed to the 1,852 CFM recorded.
