PART 2 – PRODUCTS

2.1EQUIPMENT

A.Equipment required for start-up, checking, and testing shall be calibrated within the past year and in accordance with the manufacturer’s recommendations.

PART 3 - EXECUTION

3.1CONTRACTOR’S RESPONSIBILITIES

A.Upload requested information and submittals to PSFA CIMSincluding, but not limited to:

1. Performance data

  1. Capacity information
  1. Sequence of operations
  1. Factory performance tests
  1. IOM manuals

B.Complete pre-functional checklists (PFC’s) as directed by the Performance Assurance Contractor.

C.Perform functional performance testing (PFT’s) as directed by the Performance Assurance Contractor.

D. Attend construction phase controls coordination meeting.

E.Attend testing, adjusting, and balancing review and coordination meeting.

F.Participate in HVAC systems, assemblies, equipment and component maintenance orientation and inspection as directed by the Performance Assurance Contractor.

G.Provide information requested by the PAC for final PAC documentation.

3.2CONTRACTOR’S TESTING PREPARATION

  1. Certify HVAC systems, subsystems, and equipment have been installed, calibrated, and started and are operating according to the Contract Documents.
  2. Certify HVAC instrumentation and control systems have been completed and calibrated, that they are operating according to the Contract Documents, and that pretest set points have been recorded.
  1. Set systems, subsystems, and equipment into operating mode to be tested (e.g., normal shutdown, normal auto position, normal manual position, unoccupied cycle, emergency power, and alarm conditions).
  2. Inspect and verify the position of each device and interlock identified on checklists.
  3. Check safety cutouts, alarms, and interlocks with smoke control and life-safety systems during each mode of operation.
  4. Testing Instrumentation: Install measuring instruments and logging devices to record test data as directed by the Performance Assurance Contractor .

3.3CONTRACTOR’S GENERAL TESTING REQUIREMENTS

A.Provide technicians, instrumentation, and tools to perform Performance Assurance tests at the direction of the Performance Assurance Contractor .

B. Scope of HVAC testing shall include entire HVAC installation, from central equipment for heat generation and refrigeration through distribution systems to each conditioned space. Testing shall include measuring capacities and effectiveness of operational and control functions.

C.Test all operating modes, interlocks, control responses, and responses to abnormal or emergency conditions, and verify proper response of building automation system controllers and sensors.

D.The Performance Assurance Contractor shall prepare detailed testing plans, procedures, and checklists for HVAC systems, subsystems, and equipment.

E.Tests will be performed using design conditions whenever possible.

F.Simulated conditions may need to be imposed using an artificial load when it is not practical to test under design conditions. Before simulating conditions, calibrate testing instruments. Provide equipment to simulate loads. Set simulated conditions as directed by the Performance Assurance Contractor and document simulated conditions and methods of simulation. After tests, return settings to normal operating conditions.

G.The Performance Assurance Contractor may direct that set points be altered when simulating conditions is not practical.

  1. The Performance Assurance Contractor may direct that sensor values be altered with a signal generator when design or simulating conditions and altering set points are not practical.
  2. If tests cannot be completed because of a deficiency outside the scope of the HVAC system, document the deficiency and report it to the Owner. After deficiencies are resolved, reschedule tests.
  3. If the testing plan indicates specific seasonal testing, complete appropriate initial performance tests and documentation and schedule seasonal tests.
