3.2 ACCEPTANCE PROCEDURES

A. Prior to functional performance testing of each system, the Commissioning Specialist shall observe and verify that the physical installation of components and systems being tested is substantially installed in accordance with the Contract Documents, through spot-checking and relying on documented checks of sub-contractors and/or CQC.

B. Contractor's Tests

1. System shall be checked for proper installation, shall be adjusted and calibrated to verify that it is ready to function as specified.

2. All system elements shall be checked to verify that they have been installed properly and that all connections have been made correctly.

3. All discrete elements and sub-systems shall be adjusted and checked for proper operation.

4. Start-up and operational tests shall be complete, with all required Pre-functional

Construction Checklists submitted for review by Commissioning Specialist within five

(5) days of each activity, prior to starting functional performance testing.

A. Functional Tests

1. Objective of these tests is to demonstrate that system is operating and complying with specified performance requirements.

2. Functional performance tests shall be performed on complete system. Each function shall be demonstrated to satisfaction of the Commissioning Specialist on paragraph-by-paragraph basis of Commissioning Specialist's written test procedure, developed to demonstrate conformance to requirements of the Specifications.

3. Functional performance tests shall be witnessed and endorsed by the Commissioning

Specialist upon satisfactory completion.

Section 01 11 00-Page 15

4. Actual testing program shall be conducted in accordance with approved procedures and shall be documented as required herein.

5. Contractor shall notify Contracting Officer at least two (2) weeks prior to date of each functional performance tests.

A. The functional performance testing process shall be accomplished for all equipment, sub- systems, systems and system interfaces. All must be tested for acceptances and there shall be a separate checklist for each to ensure documentation specific to each is complete.

B. Each system shall be operated through all modes of system operation (e.g., seasonal, occupied, unoccupied, warm-up, cool-down, etc., as applicable) including every individual interlock and conditional control logic, all control sequences, both full-load and part-load conditions and simulation of all abnormal conditions for which there is a specified system or controls response. The warm-up and cool-down test shall be a performance test.

C. Temporary upsets of systems, such as distribution fault, control loss, setpoint change, equilibrium upset and component failure, shall be imposed at different operation loads to determine system stability and recovery time.

D. When the functional performance of all individual systems has been proven, the interface or coordinated responses between systems shall be checked. The systems involved may be within the overall HVAC work or they may involve other systems, such as emergency systems for life safety.

E. Corrective Measures: If acceptable performance cannot be achieved, the cause of the deficiency will be identified. If it is determined that the deficiency was caused by the system or component not being installed per the manufacturer's recommendations or Contract Documents, the necessary corrective measures shall be carried out by the Contractor. Every check or test for which acceptable performance was not achieved shall be repeated after the necessary corrective measures have been completed. This re-testing process shall be repeated until acceptable performance is achieved. The

Contractor shall be financially responsible, at standard rates, to reimburse the Commissioning

Specialist for the additional time taken to achieve acceptable performance.

3.3 TEST METHODS

A. Simulating Conditions: Over-writing values through the BMS is not acceptable, unless approved by the COR. Proposed exceptions need to be identified and protocol submitted to the COR for approval.

Before simulating conditions, overwriting values (if approved), or changing set-points, sensors, transducers and devices shall have been calibrated. Below are several examples of exceptions that would be considered acceptable:

1. When "various" actual static pressures inside ductwork cannot be simulated within the duct, and where a sensor signals the BMS to initiate sequences at various duct statics, it would be considered acceptable to simulate the various pressures via Pneumatic Squeeze-

Bulb Type Signaling Device with gauge temporarily attached to the sensing tube leading to the transmitter. It would not be acceptable to reset the various set-points, nor to simulate an electric analog signal.

Section 01 11 00-Page 16

2. Dirty filter pressure drops can be simulated using sheets of cardboard at filter face.

3. Freeze-stat safeties can be simulated via packing portion of sensor with ice.

4. Heating the outside air sensor with a hair blower.

5. Using preheat coil to simulate entering cooling coil conditions.

6. Using a signal generator to simulate a sensor signal is generally not recommended for commissioning, but may be proposed for special conditions.

7. Altering set points. For example, to see the AC compressor lockout work at an outside air temperature below 55 degrees F, when the outside air temperature is above 55 degrees F, temporarily change the lockout set point to be 0 degrees F above the current outside air temperature. Caution: Set points are not to be raised or lowered to a point that would damage the components, systems, or the building structure and/or contents.

8. Duct Mounted smoke detectors to be tested per the detector manufacturer's recommendation using aerosolized smoke, and gauges on sampling tubes. Test to be done with air system at minimum airflow condition in ductwork.

9. Current sensing relays used for fan and pump status signals to BMS to indicate unit failure and run status are to be tested by resetting the trip point on the relay to a point simulating lost belt or unit failure, while the unit is running and confirming that the failure alarm was generated and received at the BMS. After test is conducted the set point is to be returned to its original set-point or set-point as indicated by the COR.

A. Setup. Each System Test checklist item shall be performed under conditions that simulate actual conditions as close as is practically possible. The Contractor or Sub executing the test shall provide all necessary materials, system modifications, etc. to produce the necessary flows, pressures, temperatures, etc. necessary to execute the test according to the specified conditions. At completion of the test, the Sub shall return affected building equipment and systems, due to these temporary modifications, to their pre-test condition.

3.4 SEASONAL COMMISSIONING AND OCCUPANCY VARIATIONS

A. Seasonal commissioning pertains to testing under full-load conditions during peak heating and peak cooling seasons, as well as part-load conditions in the spring and fall. Initial commissioning will be done as soon as contract work is completed, regardless of season. For the major heating and cooling generation and distribution systems, means of artificial loading shall be developed by the

Commissioning Specialist as a means of demonstration, to a reasonable level of confidence, the ability to handle larger peak seasonal loads. Subsequent commissioning shall be undertaken at the appropriate time thereafter to ascertain adequate performance during the different seasons.

B. All equipment and systems will be tested and commissioned in a peak season to observe full- load performance. Heating equipment will be tested during winter design extremes. Cooling equipment will be tested during summer design extremes, with a fully occupied building. Each Contractor and supplier will be responsible to participate in the initial and the alternate peak season test of the

Section 01 11 00-Page 17 systems required demonstrating performance.

C. All equipment and systems affected by occupancy variations will be tested and commissioned at the minimum and peak loads to observe system performance. Each Contactor and supplier will be responsible to participate in the occupancy sensitive testing of systems to provide verification of adequate performance.

D. Based on the scheduling of seasonal testing, the Contractor and COR shall discuss/coordinate

Beneficial Occupancy and start of warranty period for affected systems.

3.5 COMMISSIONING PHASING REQUIREMENTS

All systems and system interfaces shall be fully commissioned prior to beneficial use by the

Government at any stage of project construction. All systems and interfaces shall be re-commissioned after complete construction of entire project.
