SECTION 019115 - FUNCTIONAL PERFORMANCE TESTING PROCEDURES

PART 1 GENERAL

1.1 WORK INCLUDED

A. Functional Performance Testing of systems.

B. Documentation of FPTs.

C. Acceptance criteria.

1.2 SCOPE

A. This section describes the Functional Performance Testing (FPT) process, procedures, and requirements. It is intended to illustrate (i) the Contractor’s requirements for assisting the Commissioning Provider (Commissioning Provider) with the functional performance testing of systems, and (ii) to demonstrate the level at which systems and equipment will be tested prior to being deemed ‘Acceptable’ to the Owner.

B. The Commissioning Provider will prepare itemized and detailed testing plans and procedures that:

1. Specify individual tests and procedures that meet the requirements of the Commissioning Plan and commissioning process;

2. Serve to document and record the testing procedures and the results of the tests.

C. The Contractor shall provide technical input to the Commissioning Provider as needed during the development of the final project FPTs.

D. Example FPTs are provided as illustration to the Contractor of the level of detail to which FPTs will be conducted.

1.3 Related Work and Documents

FUNCTIONAL PERFORMANCE TESTING PROCEDURES 019115 - 2

1.4 Definitions and Abbreviations

A. Refer to Section 019113.

1.5 Functional Performance Testing

A. Objectives and Scope: Each system shall be operated through all modes of operation (seasonal, occupied, unoccupied, warm-up, cool-down, part- and full-load) where there is a specified system response in the sequence of operations. Verifying each sequence in the sequences of operation is required. Proper responses to such modes and conditions as power failure, freeze condition, low oil pressure, no flow, equipment failure, etc. shall also be tested

1. Normal Operation: Each system shall be operated through all modes of operation (seasonal, occupied, unoccupied, warm-up, cool-down, part- and full-load) where there is a specified system response in the sequence of operations. These series of tests will demonstrate that the systems and equipment operate throughout typical operation including normal adjusting, cleaning, media replacement, and maintenance.

2. Abnormal Operation: Test each system to simulate possible abnormal conditions and verify proper responses to such modes and conditions as power failure, equipment and component failure, freeze condition, deviation of operating parameters outside of normal, no flow, supporting utility failure, human error, etc. This series of tests shall demonstrate proper and safe response to the tested systems and the other systems that it affects or with which it integrates. These tests shall also demonstrate proper alarming of abnormal conditions to quickly and effectively notify users and operators of such condition. Specific modes required in this project are given in this section and any other sections where test requirements are found.

B. Development of Test Procedures. The Commissioning Provider shall develop specific test procedures and forms to verify and document proper operation of each piece of equipment and system. Prior to execution, the Commissioning Provider shall provide a copy of the test procedures to the Contractor who shall review the tests for feasibility, safety, equipment and warranty protection, and scope. The Commissioning Provider will also submit the tests to the A/E for review.

1. Contractor shall review the FPTs in detail and approve them.

2. The Commissioning Provider shall review Owner-contracted testing, factory testing, or required Owner acceptance tests for which the Commissioning Provider is not responsible to oversee. Review shall include content, scope, and documentation format, and shall determine what further testing or format changes may be required. Redundancy of testing shall be minimized.

3. The purpose of any given specific FPT is to verify and document compliance with the stated criteria of acceptance.

C. Scheduling: After Contractor’s notification that systems are ready for functional testing and review of all the required submittals has occurred, the Construction Manager shall schedule the testing. To the extent practical, tests shall be scheduled to allow efficient and contiguous testing of inter-related systems and equipment.

FUNCTIONAL PERFORMANCE TESTING PROCEDURES 019115 - 3

D. Participation: The Commissioning Provider will direct and conduct functional performance tests after Start-Up Procedure and Construction Checklist documentation of systems and equipment have been reviewed and accepted. Conceptual procedures for the functional performance testing are outlined elsewhere in this Section. The Commissioning Provider will execute the FPTs unless otherwise specified. The Contractor shall assist as described above with manipulation of the systems or equipment, provision of supporting equipment or materials (lifts, ladders, specialty test equipment, safety equipment), and on-the-spot remediation of minor identified deficiencies whenever possible. Required participation is outlined in the generic FPTs provided elsewhere in this Section.

1. Required participating Parties shall be indicated with the individual FPT. Typically, multiple Parties are required for any given test, yet participation for any given Party is only required for the respective portion of the test for which the Party is responsible.

2. On multiple samples where a given Party does not directly conduct the test, the participation of that Party will only be required for an initial quantity of systems/equipment.

Whenever practical and at the discretion of the Commissioning Provider, the Commissioning Provider will continue with the remaining portion of the sample without assistance from the Contractor. The Contractor is allowed to be present at their option for any or all FPTs conducted.

3. It is required that the required Parties be available on-site throughout the testing of any given system for which they are required participants. Therefore, time for which they are not directly involved can be spent performing other work (typically addressing identified punch list items or failed tests).

4. No Party involved with the project is prohibited from participation in or witnessing of any tests. Any Contractor may elect to witness all tests on their systems even if their involvement is not directly.

5. The Commissioning Provider will endeavor to coordinate effectively with the individual Contractors throughout FPTs and minimize their required involvement.

6. Contractor assumes responsibility for damage to systems conducted in accordance with the approved procedures.

E. Detailed Test Procedures and Contractor Review: The Commissioning Provider will prepare detailed and itemized testing procedures to define and document the FPTs. These will be developed during the Construction Phase and completed during the Acceptance Phase. The Commissioning Provider shall submit these procedures to the Contractor for review. Contractor shall indicate all required limitations, safety procedures, maximum thresholds, and any other parameters during the FPT development. Contract shall be responsible for any damage to the equipment caused by functional performance testing done per the procedures and within the limitations of the approved procedures.

F. Completeness: All systems must be completed and ready for FPT. All start up, factory authorized field testing, independent testing agency tests, and TAB procedures must be complete, and the control systems must be tested and started for the respective system or component.

G. Test Documentation: Commissioning Provider will conduct tests, and/or witness tests as applicable. Commissioning Provider will record all test results on the forms developed for the testing. Commissioning Provider will ‘Pass’ or ‘Fail’ the testing and record the date and time of the test. Deficiencies shall clearly be indicated when the test is failed. When all related testing is completed successfully, the Commissioning Provider shall recommend acceptance of the system or component.

FUNCTIONAL PERFORMANCE TESTING PROCEDURES 019115 - 4

H. Deficiencies and Re-Testing: When deficiencies are identified during testing, depending on their extent or magnitude, they can be corrected during the test and the testing can continue to successful completion. More significant deficiencies will require failure of the test and re-testing. Deficiencies of this magnitude will result in an Action Item on the Action List. The resolution of the deficiency will then subsequently be tracked by the Commissioning Provider via the Action List. All tests shall be repeated until successful completion. Refer to more specific provisions below.

I. Sampling: Some types of identical equipment (such as terminal devices) will be tested using a sampling strategy. The sample percentage is indicated in the Commissioning Plan.

J. Max Failure Limit and Sample Percentages: A Maximum Failure Limit is indicated along with the Sampling Percentages. The Max Failure Limit indicates the maximum percentage of the tested devices that may have any test that fails before an entirely new sample must be tested.

This is based on the concept that if many failures occur, it is a result of inadequate start-up by the Contractor. When the maximum number of failures is reached, testing on that sample will be terminated and re-testing will be scheduled.

1. If no Max Failure Limit is indicated, all tested samples must pass (Max Failure Limit 0%).

2. Where sample tests involve multiple systems (i.e., checking strainers on different hydronic systems) the Maximum Failure Limit will apply per system.

3. The responsible Contractors shall pay the Commissioning Provider cost of that sample test and redo the start-up/TAB for the applicable devices/systems.

4. All work necessitated by sample failures shall be at no cost to the Owner.

K. Opposite Season Testing: Testing procedures shall be repeated and/or conducted as necessary during appropriate seasons. Opposite Season testing will be required where scheduling prohibits thorough testing in all modes of operation. Air handler and central heating system testing for heating-related modes of operation and control loops shall be tested during outside air temperatures below 35°F.

L. Approval: The Commissioning Provider passes each test and subsequently recommends acceptance to the Owner or Construction Manager who reviews and accepts the results of the

FPT.

1.6 Coordination Between Testing Parties.

A. Factory Start-Ups: For many systems and equipment, Factory Start-Ups are specified. These Factory Start-Ups will be reviewed and checked during functional performance testing. All costs associated with the Factory Start-Ups are included with the bid unless otherwise noted. In general, Contractor shall make notification of when Factory Start-Ups are occurring and coordinate these with witnessing Parties. The Commissioning Provider and commissioning team members may witness Factory Start-Ups at their discretion. Aspects of functional performance testing accomplished during the Factory Start-Ups may be accomplished and approved by the Commissioning Provider if they meet the intent of the FPT.

B. Independent Testing Agencies: For systems where Independent Testing Agencies are specified, the cost of this testing is included with the bid unless otherwise noted. Much of the testing performed by these independent agencies will cover aspects required in the Start-Up Procedures and functional performance tests.

FUNCTIONAL PERFORMANCE TESTING PROCEDURES 019115 - 5

1. Contractor and testing agencies shall coordinate with the Commissioning Provider so that the Commissioning Provider can witness the testing and approve the applicable aspects of the FPTs.

2. The Commissioning Provider may in some cases independently spot-check work of the testing agencies if the tests were not witnessed. However, it is not the intent for the Commissioning Provider to re-accomplish testing by others that is specified in the construction specifications.

3. Contractor is responsible for coordinating the efforts of the testing agency with that of the commissioning process. Documentation shall be contiguous and seamless, and duplication should be avoided. Testing agencies shall complete the documentation of the commissioning process as required.

C. Specialized Testing by Contractor: Where specialized testing is specified in the technical specifications, Contractor, subcontractor, vendor, or factory representative as applicable shall conduct the specified testing and provide all specialized instrumentation and equipment.

Commissioning Provider and other commissioning team members may witness tests at their discretion. The Commissioning Provider may in some cases independently spot-check the results of the tests if the tests were not witnessed. However, it is not the intent for the Commissioning Provider to re-accomplish testing that is specified in the construction specifications. All specialized testing procedures shall be integrated with the Cx process and all documentation shall be coordinated and integrated with the documentation of the Cx process.

Examples of specialized testing include:

1. Generator load testing (not building power outage functional testing which will be administered by Commissioning Provider)

2. Acceptance testing of the Fire Alarm System

3. Fire suppression system hydraulic tests

4. Laboratory Gas Cross Connection testing

1.2 GENERAL DESCRIPTION

A. Commissioning (Cx) is the process of ensuring that all building systems are installed and perform interactively according to the design intent; that systems are efficient and cost effective and meet the Owner’s operational needs; that the installation is adequately documented; and that the Operators are adequately trained. It serves as a tool to minimize post-occupancy operational problems. It establishes testing and communication protocols in an effort to advance the building systems from installation to full dynamic operation and optimization.

B. Commissioning Authority shall work with the Contractors, the GC, the CM, and the Design Team to direct and oversee the Cx process.

C. The Commissioning Plan outlines the commissioning process beyond the Construction Documents. The specification sections dictate all requirements of the commissioning process relative to the construction contract. The Cx Plan is available for reference at the request of the Contractor; however, it is not part of the construction contract.

D. This Section and other Sections of the specification detail the Contractor’s responsibilities relative to the Cx process.
