May 11, 2018 Commissioning of HVAC Systems


SECTION 230800 – COMMISSIONING OF HVAC SYSTEMS

PART 1 - GENERAL

1.1 DESCRIPTION

A. Commissioning. Commissioning is a systematic process of ensuring that all building systems

perform interactively according to the design intent and the owner’s operational needs. This is

achieved by beginning in the design phase and documenting design intent and continuing through

construction, acceptance and the warranty period with actual verification of performance. The

commissioning process shall encompass and coordinate the traditionally separate functions of

system documentation, equipment startup, control system calibration, testing and balancing,

performance testing and training.

Commissioning during the construction phase is intended to achieve the following specific

objectives according to the Contract Documents:

1) 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.

2) Verify and document proper performance of equipment and systems.

3) Verify that O&M documentation left on site is complete.

4) Verify that the Owner’s operating personnel are adequately trained.

B. The commissioning process does not take away from or reduce the responsibility of the system

designers or installing contractors to provide a finished and fully functioning product.

C. Abbreviations. The following are common abbreviations used in this Specification and in the

Commissioning Plan to be developed. Definitions are found in Section 1.6.

A/E- Architect and design engineers FT- Functional performance test

CA- Commissioning authority GC- General contractor (prime)

CC Controls contractor MC- Mechanical contractor

CM- Construction Manager (the owner’s

representative)

PC- Prefunctional checklist

Cx- Commissioning PM- Project manager (of the Owner)

Cx Plan- Commissioning Plan document Subs- Subcontractors to General

EC- Electrical contractor TAB- Test and balance contractor


(BID #2205-18)



1.2 COORDINATION

A. Commissioning Team. The members of the commissioning team consist of the Commissioning

authority (CA), the Project Manager (PM), , the General Contractor (GC or Contractor), the

architect and design engineers (particularly the mechanical engineer), the Mechanical Contractor

(MC), the Electrical Contractor (EC), the TAB representative, the Controls Contractor (CC), any

other installing subcontractors or suppliers of equipment. If known, the Owner’s building or plant

operator/engineer is also a member of the commissioning team.

B. Management. The CA will be Landmark Facilities Group, Inc. The CA directs and coordinates

the commissioning activities.

C. Scheduling. The CA will work with the Contractor according to established protocols to schedule

the commissioning activities. The CA will provide sufficient notice to the Contractor for

scheduling commissioning activities. The Contractor will integrate all commissioning activities

into the master schedule. All parties will address scheduling problems and make necessary

notifications in a timely manner in order to expedite the commissioning process.

The Contractor will provide the initial schedule of primary commissioning events at the

commissioning scoping meeting. The Commissioning Plan—Construction Phase shall provide a

format for this schedule. As construction progresses more detailed schedules are developed by the

CA. The Commissioning Plan shall also provide a format for detailed schedules.

1.3 COMMISSIONING PROCESS

A. Commissioning Specifications. The commissioning specifications shall be provided as part of the

bid documents and is binding on the Contractor. The commissioning plan provides guidance in

the execution of the commissioning process. The CA shall present a preliminary Commissioning

Plan for the Construction Phase at the pre-construction or initial commissioning coordination

meeting. Just after the initial commissioning scoping meeting the CA will update the plan which

is then considered the “final” plan, though it will continue to evolve and expand as the project

progresses. The Specifications will take precedence over the Commissioning Plan.

B. Commissioning Process. The following narrative provides a brief overview of the typical

commissioning tasks during construction and the general order in which they occur.

1. Commissioning during construction begins with a scoping meeting conducted by the CA

where the commissioning process is reviewed with the commissioning team members.

2. Additional meetings will be required throughout construction, scheduled by the CA with

necessary parties attending, to plan, scope, coordinate, schedule future activities and resolve

problems.

3. Equipment documentation is submitted to the CA during normal submittals, including

detailed start-up procedures.

4. The CA works with the Subs in developing startup plans and startup documentation formats,

including providing the Subs with prefunctional checklists to be completed, during the startup

process.

5. In general, the checkout and performance verification proceeds from simple to complex; from

component level to equipment to systems and intersystem levels with prefunctional checklists

being completed before functional testing.


(BID #2205-18)



6. The Subs, under their own direction, execute and document the prefunctional checklists and

perform startup and initial checkout. The CA documents that the checklists and startup were

completed according to the approved plans. This may include the CA witnessing start-up of

selected equipment.

7. The CA develops specific equipment and system functional performance test procedures.

The Subs review the procedures.

8. The procedures are executed by the Subs, under the direction of, and documented by, the CA.

9. Items of non-compliance in material, installation or setup are corrected at the Sub’s expense

and the system retested.

10. The CA reviews the O&M documentation for completeness.

11. Commissioning is completed before Substantial Completion.

12. The CA reviews, pre-approves and coordinates the training provided by the Subs and verifies

that is was completed.

13. Deferred testing is conducted, as specified or required.

1.6 DEFINITIONS

Acceptance Phase - phase of construction after startup and initial checkout when functional performance tests,

O&M documentation review and training occurs.

Approval - acceptance that a piece of equipment or system has been properly installed and is functioning in the

tested modes according to the Contract Documents.

Architect / Engineer (A/E) - the architect and engineering consultants who comprise the design team, generally

the HVAC mechanical designer/engineer and the electrical designer/engineer.


(BID #2205-18)



Commissioning authority (CA) - an independent agent, not otherwise associated with the A/E team members or

the Contractor. The CA directs and coordinates the day-to-day commissioning activities

Commissioning Plan - an overall plan, developed after bidding that provides the structure, schedule and

coordination planning for the commissioning process.

Control system - the central building energy management control system (or DDC System).

Datalogging - monitoring flows, currents, status, pressures, etc. of equipment using stand-alone dataloggers

separate from the control system.

Deferred Functional Tests - FTs that are performed later, after substantial completion, due to partial occupancy,

equipment, seasonal requirements, design or other site conditions that disallow the test from being

performed.

Deficiency - a condition in the installation or function of a component, piece of equipment or system that is not

in compliance with the Contract Documents (that is, does not perform properly or is not complying

with the design intent).

Design Intent - a dynamic document that provides the explanation of the ideas, concepts and criteria that are

considered to be very important to the owner. It is initially the outcome of the programming and

conceptual design phases.

Design Narrative or Design Documentation - sections of either the Design Intent or Basis of Design.

Factory Testing - testing of equipment on-site or at the factory by factory personnel with an Owner’s

representative present.

Functional Performance Test (FT) - test of the dynamic function and operation of equipment and systems using

manual (direct observation) or monitoring methods. 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

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 the control system’s sequences of operation and components are

verified to be responding as the sequences state. Traditional air or water test and balancing (TAB) is

not functional testing, in the commissioning sense of the word. TAB’s primary work is setting up the

system flows and pressures as specified, while functional testing is verifying that which has already

been set up. 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. FTs are performed after prefunctional checklists and startup are

complete.

Indirect Indicators - indicators of a response or condition, such as a reading from a control system screen

reporting a damper to be 100% closed.

Manual Test - using hand-held instruments, immediate control system readouts or direct observation to verify

performance (contrasted to analyzing monitored data taken over time to make the “observation”).

Monitoring - the recording of parameters (flow, current, status, pressure, etc.) of equipment operation using

dataloggers or the trending capabilities of control systems.

Non-Compliance - see Deficiency.

Non-Conformance - see Deficiency.

Over-written Value - writing over a sensor value in the control system to see the response of a system (e.g.,

changing the outside air temperature value from 50F to 75F to verify economizer operation). See also

“Simulated Signal.”

Owner-Contracted Tests - tests paid for by the Owner outside the GC’s contract and for which the CA does not

oversee. These tests will not be repeated during functional tests if properly documented.

Phased Commissioning - commissioning that is completed in phases (by floors, for example) due to the size of

the structure or other scheduling issues, in order minimize the total construction time.

Prefunctional Checklist (PC) - a list of items to inspect and elementary component tests to conduct to verify

proper installation of equipment, provided by the CA to the Sub. Prefunctional checklists are primarily


(BID #2205-18)



static inspections and procedures to prepare the equipment or system for initial operation (e.g., belt

tension, oil levels OK, labels affixed, gages in place, sensors calibrated, etc.). However, some

prefunctional 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 word prefunctional refers to before functional testing. Prefunctional checklists augment and are

combined with the manufacturer’s start-up checklist. Even without a commissioning process,

contractors typically perform some, if not many, of the prefunctional checklist items a commissioning

authority will recommend. However, few contractors document in writing the execution of these

checklist items. Therefore, for most equipment, the contractors execute the checklists on their own.

The commissioning authority only requires that the procedures be documented in writing, and does not

witness much of the prefunctional checklisting, except for larger or more critical pieces of equipment.

Project Manager (PM) - the contracting and managing authority for the owner over the design and/or

construction of the project, a staff position.

Sampling. - functionally testing only a fraction of the total number of identical or near identical pieces of

equipment. Refer to Section 019113, Part 3.6, F for details.

Seasonal Performance Tests - FT that are deferred until the system(s) will experience conditions closer to their

design conditions.

Simulated Condition - condition that is created for the purpose of testing the response of a system (e.g.,

applying a hair blower to a space sensor to see the response in a VAV box).

Simulated Signal - disconnecting a sensor and using a signal generator to send an amperage, resistance or

pressure to the transducer and DDC system to simulate a sensor value.

Startup - the initial starting or activating of dynamic equipment, including executing prefunctional checklists.

Test Procedures - the step-by-step process which must be executed to fulfill the test requirements. The test

procedures are developed by the CA.

Test Requirements - requirements specifying what modes and functions, etc. shall be tested. The test

requirements are not the detailed test procedures. The test requirements are specified in the Division

23 Specifications.(

Trending - monitoring using the building control system.

Vendor - supplier of equipment.

Warranty Period - warranty period for entire project, including equipment components. Warranty begins at

Substantial Completion and extends for at least one year, unless specifically noted otherwise in the

Contract Documents and accepted submittals.

PART 3 - EXECUTION

3.1 MEETINGS

A. Scoping Meeting. Within 60 days of commencement of construction, the CA will schedule, plan

and conduct a commissioning scoping meeting with the entire commissioning team in attendance.

Meeting minutes will be distributed to all parties by the CA. Information gathered from this

meeting will allow the CA to revise the Commissioning Plan to its “final” version, which will also

be distributed to all parties.

B. Miscellaneous Meetings. Other meetings will be planned and conducted by the CA as

construction progresses. These meetings will cover coordination, deficiency resolution and

planning issues with particular Subs. The CA will plan these meetings and will minimize

unnecessary time being spent by Subs. For large projects, these meetings may be held monthly,

until the final 3 months of construction when they may be held as frequently as one per week.

3.2 REPORTING

A. The CA will provide regular reports to the PM, depending on the management structure, with

increasing frequency as construction and commissioning progresses. Standard forms are provided

and referenced in the Commissioning Plan.

B. The CA will regularly communicate with all members of the commissioning team, keeping them

apprised of commissioning progress and scheduling changes through memos, progress reports, etc.

C. Testing or review approvals and non-conformance and deficiency reports are made regularly with

the review and testing as described in later sections.

D. A final summary report (about four to six pages, not including backup documentation) by the CA

will be provided to the PM, focusing on evaluating commissioning process issues and identifying

areas where the process could be improved. All acquired documentation, logs, minutes, reports,

deficiency lists, communications, findings, unresolved issues, etc., will be compiled in appendices

and provided with the summary report. Prefunctional checklists, functional tests and monitoring

reports will not be part of the final report, but will be stored in the Commissioning Record in the

O&M manuals.


(BID #2205-18)



3.3 SUBMITTALS

A. The CA will provide appropriate contractors with a specific request for the type of submittal

documentation the CA requires to facilitate the commissioning work. These requests will be

integrated into the normal submittal process and protocol of the construction team. At minimum,

the request will include the manufacturer and model number, the manufacturer’s printed

installation and detailed start-up procedures, full sequences of operation, O&M data, performance

data, any performance test procedures, control drawings and details of owner contracted tests. In

addition, the installation and checkout materials that are actually shipped inside the equipment and

the actual field checkout sheet forms to be used by the factory or field technicians shall be

submitted to the Commissioning authority. All documentation requested by the CA will be

included by the Subs in their O&M manual contributions.

B. The Commissioning authority will review and approve submittals related to the commissioned

equipment for conformance to the Contract Documents as it relates to the commissioning process,

to the functional performance of the equipment and adequacy for developing test procedures. This

review is intended primarily to aid in the development of functional testing procedures and only

secondarily to verify compliance with equipment specifications. The Commissioning authority

will notify the, PM or A/E as requested, of items missing or areas that are not in conformance with

Contract Documents and which require resubmission.

C. The CA may request additional design narrative from the Controls Contractor, depending on the

completeness of the design intent documentation and sequences provided with the Specifications.

D. These submittals to the CA do not constitute compliance for O&M manual documentation. The

O&M manuals are the responsibility of the Contractor, though the CA will review and approve

them.

3.4 START-UP, PREFUNCTIONAL CHECKLISTS AND INITIAL CHECKOUT

A. The following procedures apply to all equipment to be commissioned, according to Section 1.7,

Systems to be Commissioned. Some systems that are not comprised so much of actual dynamic

machinery, e.g., electrical system power quality, may have very simplified PCs and startup.

B. General. Prefunctional checklists are important to ensure that the equipment and systems are

hooked up and operational. It ensures that functional performance testing (in-depth system

checkout) may proceed without unnecessary delays. Each piece of equipment receives full

prefunctional checkout. No sampling strategies are used. The prefunctional testing for a given

system must be successfully completed prior to formal functional performance testing of

equipment or subsystems of the given system.

C. Start-up and Initial Checkout Plan. The CA shall assist the commissioning team members

responsible for startup of any equipment in developing detailed start-up plans for all equipment.

The primary role of the CA in this process is to ensure that there is written documentation that

each of the manufacturer-recommended procedures have been completed. Parties responsible for

prefunctional checklists and startup are identified in the commissioning scoping meeting and in the

checklist forms. Parties responsible for executing functional performance tests are identified in the

testing requirements in Section 230800.


(BID #2205-18)



1. The CA develops, if necessary, the representative prefunctional checklists based on the

examples provided in this Section 019113. These checklists indicate required procedures to

be executed as part of startup and initial checkout of the systems and the party responsible for

their execution. The checklists will be provided as part of the Commissioning Plan –

Construction Phase.

2. These checklists and tests are provided by the CA to the Contractor. The Contractor

determines which trade is responsible for executing and documenting each of the line item

tasks and notes that trade on the form. Each form will have more than one trade responsible

for its execution.

3. The subcontractor responsible for the purchase of the equipment develops the full start-up

plan by combining (or adding to) the CA’s checklists with the manufacturer’s detailed start-

up and checkout procedures from the O&M manual and the normally used field checkout

sheets. The plan will include checklists and procedures with specific boxes or lines for

recording and documenting the checking and inspections of each procedure and a summary

statement with a signature block at the end of the plan.

The full start-up plan could consist of something as simple as:

a. The CA’s prefunctional checklists.

b. The manufacturer’s standard written start-up procedures copied from the installation

manuals with check boxes by each procedure and a signature block added by hand at

the end.

c. The manufacturer’s normally used field checkout sheets.

4. The subcontractor submits the full startup plan to the CA for review and approval.

5. The CA reviews and approves the procedures and the format for documenting them, noting

any procedures that need to be added.

6. The full start-up procedures and the approval form may be provided to the A/E or PM for

review and approval, depending on management protocol.

D. Sensor and Actuator Calibration.

All field-installed temperature, relative humidity, CO2 and pressure sensors and gages, and all

actuators (dampers and valves) on all equipment shall be calibrated using the methods described

below. Alternate methods may be used, if approved by the Owner before-hand. All test

instruments shall have had a certified calibration within the last 12 months. Sensors installed in the

unit at the factory with calibration certification provided need not be field calibrated.

All procedures used shall be fully documented on the prefunctional checklists or other suitable

forms, clearly referencing the procedures followed and written documentation of initial,

intermediate and final results.

Sensor Calibration Methods

All Sensors. Verify that all sensor locations are appropriate and away from causes of erratic

operation. Verify that sensors with shielded cable, are grounded only at one end. For sensor pairs

that are used to determine a temperature or pressure difference, make sure they are reading within

0.2°F of each other for temperature and within a tolerance equal to 2% of the reading, of each

other, for pressure. Tolerances for critical applications may be tighter.

Sensors Without Transmitters--Standard Application. Make a reading with a calibrated test

instrument within 6 inches of the site sensor. Verify that the sensor reading (via the permanent

thermostat, gage or building automation system (BAS)) is within the tolerances in the table below

of the instrument-measured value. If not, install offset in BAS, calibrate or replace sensor.


(BID #2205-18)



Sensors With Transmitters--Standard Application. Disconnect sensor. Connect a signal generator

in place of sensor. Connect ammeter in series between transmitter and BAS control panel. Using

manufacturer’s resistance-temperature data, simulate minimum desired temperature. Adjust

transmitter potentiometer zero until 4 mA or 0 VDC is read by the ammeter/voltmeter. Repeat for

the maximum temperature matching 20 mA or 10VDC to the potentiometer span or maximum and

verify at the BAS. Record all values and recalibrate controller as necessary to conform with

specified control ramps, reset schedules, proportional relationship, reset relationship and P/I

reaction. Reconnect sensor. Make a reading with a calibrated test instrument within 6 inches of

the site sensor. Verify that the sensor reading (via the permanent thermostat, gage or building

automation system (BAS)) is within the tolerances in the table below of the instrument-measured

value. If not, replace sensor and repeat. For pressure sensors, perform a similar process with a

suitable signal generator.

Critical Applications. For critical applications (process, manufacturing, etc.) more rigorous

calibration techniques may be required for selected sensors. Describe any such methods used on

an attached sheet.

that valve or damper is closed and adjust output zero signal as required. Command valve or

damper open, verify position is full open and adjust output signal as required. Command valve or

damper to a few intermediate positions.

Closure for heating coil valves (NO): Set heating setpoint 20°F above room temperature. Observe

valve open. Remove control air or power from the valve and verify that the valve stem and

actuator position do not change. Restore to normal. Set heating setpoint to 20°F below room

temperature. Observe the valve close. Restore to normal.

Closure for cooling coil valves (NC): Set cooling setpoint 20°F above room temperature. Observe

the valve close. Remove control air or power from the valve and verify that the valve stem and

actuator position do not change. Restore to normal. Set cooling setpoint to 20°F below room

temperature. Observe valve open. Restore to normal.

E. Execution of Prefunctional Checklists and Startup.

1. Four weeks prior to startup, the Subs and vendors schedule startup and checkout with the,

Contractor and CA. The performance of the prefunctional checklists, startup and checkout


(BID #2205-18)



are directed and executed by the Sub or vendor. When checking off prefunctional checklists,

signatures may be required of other Subs for verification of completion of their work.

2. The CA shall observe, at minimum, the procedures for each piece of primary equipment,

unless there are multiple units, (in which case a sampling strategy may be used as approved

by the A/E). In no case will the number of units witnessed be less than four on any one

building, nor less than 20% of the total number of identical or very similar units.

3. For lower-level components of equipment, (e.g., VAV boxes, sensors, controllers), the CA

shall observe a sampling of the prefunctional and start-up procedures. The sampling

procedures shall be identified in the commissioning plan.

4. The Subs and vendors shall execute startup and provide the CA with a signed and dated copy

of the completed start-up and prefunctional tests and checklists.

5. Only individuals that have direct knowledge and witnessed that a line item task on the

prefunctional checklist was actually performed shall initial or check that item off. It is not

acceptable for witnessing supervisors to fill out these forms.

F. Deficiencies, Non-Conformance and Approval in Checklists and Startup.

1. The Subs shall clearly list any outstanding items of the initial start-up and prefunctional

procedures that were not completed successfully, at the bottom of the procedures form or on

an attached sheet. The procedures form and any outstanding deficiencies are provided to the

CA within two days of test completion.

2. The CA reviews the report and submits either a non-compliance report or an approval form to

the Sub or PM. The CA shall work with the Subs and vendors to correct and retest

deficiencies or uncompleted items. The CA will involve the Contractor and others as

necessary. The installing Subs or vendors shall correct all areas that are deficient or

incomplete in the checklists and tests in a timely manner, and shall notify the CA as soon as

outstanding items have been corrected and resubmit an updated start-up report and a

Statement of Correction on the original non-compliance report. When satisfactorily

completed, the CA recommends approval of the execution of the checklists and startup of

each system to the Contractor using a standard form.

3. Items left incomplete, which later cause deficiencies or delays during functional testing may

result in backcharges to the responsible party. Refer to Part 3.7 herein for details.

3.5 PHASED COMMISSIONING

A. Phasing will be planned and scheduled, if necessary, in a coordination meeting of the CA, ,

mechanical, TAB and controls and the Contractor. Results will be added to the master and

commissioning schedule.

3.6 FUNCTIONAL PERFORMANCE TESTING

A. This sub-section applies to all commissioning functional testing for all divisions.

B. The general list of equipment to be commissioned is found in Section 019113, Part 1.7. The

specific equipment and modes to be tested are found in the Division 23 Sections

C. The parties responsible to execute each test are listed with each test in Section 230800

D. Objectives and Scope. The objective of functional performance testing is to demonstrate that each

system is operating according to the documented design intent and Contract Documents.

Functional testing facilitates bringing the systems from a state of substantial completion to full


(BID #2205-18)



dynamic operation. Additionally, during the testing process, areas of deficient performance are

identified and corrected, improving the operation and functioning of the systems.

In general, each system should 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.

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. Specific modes required in this project are given in the Division

23 Sections .

E. Development of Test Procedures. Before test procedures are written, the CA shall obtain all

requested documentation and a current list of change orders affecting equipment or systems,

including an updated points list, program code, control sequences and parameters. Using the

testing parameters and requirements in Division 23 , the CA shall develop specific test procedures

and forms to verify and document proper operation of each piece of equipment and system. Each

Sub or vendor responsible to execute a test, shall provide limited assistance to the CA in

developing the procedures review (answering questions about equipment, operation, sequences,

etc.). Prior to execution, the CA shall provide a copy of the test procedures to the Sub(s) who shall

review the tests for feasibility, safety, equipment and warranty protection. The CA may submit the

tests to the A/E for review, if requested.

The CA shall review owner-contracted, factory testing or required owner acceptance tests which

the CA is not responsible to oversee, including documentation format, and shall determine what

further testing or format changes may be required to comply with the Specifications. Redundancy

of testing shall be minimized.

The purpose of any given specific test is to verify and document compliance with the stated

criteria of acceptance given on the test form.

The test procedure forms developed by the CA shall include (but not be limited to) the following

information:

1. System and equipment or component name(s)

2. Equipment location and ID number

3. Unique test ID number, and reference to unique prefunctional checklist and start-up

documentation ID numbers for the piece of equipment

4. Date

5. Project name

6. Participating parties

7. A copy of the specification section describing the test requirements

8. A copy of the specific sequence of operations or other specified parameters being verified

9. Formulas used in any calculations

10. Required pre-test field measurements

11. Instructions for setting up the test.

12. Special cautions, alarm limits, etc.

13. Specific step-by-step procedures to execute the test, in a clear, sequential and repeatable

format

14. Acceptance criteria of proper performance with a Yes / No check box to allow for clearly

marking whether or not proper performance of each part of the test was achieved.

15. A section for comments

16. Signatures and date block for the CA


(BID #2205-18)



F. Test Methods.

1. Functional performance 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

dataloggers. Division 23 sections specify which methods shall be used for each test. The CA

may substitute specified methods or require an additional method to be executed, other than

what was specified, with the approval of the A/E. This may require a change order and

adjustment in charge to the Owner. The CA will determine which method is most

appropriate for tests that do not have a method specified.

2. Simulated Conditions. Simulating conditions (not by an overwritten value) shall be allowed,

though timing the testing to experience actual conditions is encouraged wherever practical.

3. Overwritten Values. Overwriting sensor values to simulate a condition, such as overwriting

the outside air temperature reading in a control system to be something other than it really is,

shall be allowed, but shall be used with caution and avoided when possible. Such testing

methods often can only test a part of a system, as the interactions and responses of other

systems will be erroneous or not applicable. Simulating a condition is preferable. e.g., for the

above case, by heating the outside air sensor with a hair blower rather than overwriting the

value or by altering the appropriate setpoint to see the desired response. Before simulating

conditions or overwriting values, sensors, transducers and devices shall have been calibrated.

4. Simulated Signals. Using a signal generator which creates a simulated signal to test and

calibrate transducers and DDC constants is generally recommended over using the sensor to

act as the signal generator via simulated conditions or overwritten values.

5. Altering Setpoints. Rather than overwriting sensor values, and when simulating conditions is

difficult, altering setpoints to test a sequence is acceptable. For example, to see the AC

compressor lockout work at an outside air temperature below 55F, when the outside air

temperature is above 55F, temporarily change the lockout setpoint to be 2F above the current

outside air temperature.

6. Indirect Indicators. Relying on indirect indicators for responses or performance shall be

allowed only after visually and directly verifying and documenting, over the range of the

tested parameters, that the indirect readings through the control system represent actual

conditions and responses. Much of this verification is completed during prefunctional

testing.

7. Setup. Each function and test shall be performed under conditions that simulate actual

conditions as close as is practically possible. The 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 all affected building equipment and systems, due

to these temporary modifications, to their pre-test condition.

8. Sampling. Multiple identical pieces of non-life-safety or otherwise non-critical equipment

may be functionally tested using a sampling strategy. Significant application differences and

significant sequence of operation differences in otherwise identical equipment invalidates

their common identity. A small size or capacity difference, alone, does not constitute a

difference. It is noted that no sampling by Subs is allowed in prefunctional checklist

execution.

A common sampling strategy referenced in the Specifications as the “xx% Sampling—yy%

Failure Rule” is defined by the following example.

xx = the percent of the group of identical equipment to be included in each sample.


(BID #2205-18)



yy = the percent of the sample that if failing, will require another sample to be tested.

The example below describes a 20% Sampling—10% Failure Rule.

a. Randomly test at least 20% (xx) of each group of identical equipment. In no case test

less than three units in each group. This 20%, or three, constitute the “first sample.”

b. If 10% (yy) of the units in the first sample fail the functional performance tests, test

another 20% of the group (the second sample).

c. If 10% of the units in the second sample fail, test all remaining units in the whole

group.

d. If at any point, frequent failures are occurring and testing is becoming more

troubleshooting than verification, the CA may stop the testing and require the

responsible Sub to perform and document a checkout of the remaining units, prior to

continuing with functionally testing the remaining units.

G. Coordination and Scheduling. The Subs shall provide sufficient notice to the CA regarding their

completion schedule for the prefunctional checklists and startup of all equipment and systems.

The CA will schedule functional tests through the, Contractor. The CA shall direct, witness and

document the functional testing of all equipment and systems. The Subs shall execute the tests.

In general, functional testing is conducted after prefunctional testing and startup has been

satisfactorily completed. The control system is sufficiently tested and approved by the CA before

it is used for TAB or to verify performance of other components or systems. The air balancing

and water balancing is completed and debugged before functional testing of air-related or water-

related equipment or systems. Testing proceeds from components to subsystems to systems.

When the proper performance of all interacting individual systems has been achieved, the interface

or coordinated responses between systems is checked.

H. Test Equipment. Refer to Section 019113, Part 2.1 for test equipment requirements.

3.7 DOCUMENTATION, NON-CONFORMANCE AND APPROVAL OF TESTS

A. Documentation. The CA shall witness and document the results of all functional performance

tests using the specific procedural forms developed for that purpose. Prior to testing, these forms

are provided to the Contractor for review and approval. The CA will include the filled out forms

in the O&M manuals.

B. Non-Conformance.

1. The CA will record the results of the functional test on the procedure or test form. All

deficiencies or non-conformance issues shall be noted and reported to the Contractor on a

standard non-compliance form.

2. Corrections of minor deficiencies identified may be made during the tests at the discretion of

the CA. In such cases the deficiency and resolution will be documented on the procedure

form.

3. Every effort will be made to expedite the testing process and minimize unnecessary delays,

while not compromising the integrity of the procedures. However, the CA will not be

pressured into overlooking deficient work or loosening acceptance criteria to satisfy

scheduling or cost issues, unless there is an overriding reason to do so at the request of the

PM.


(BID #2205-18)



4. As tests progress and a deficiency is identified, the CA discusses the issue with the executing

contractor.

a. When there is no dispute on the deficiency and the Sub accepts responsibility to correct

it:

1) The CA documents the deficiency and the Sub’s response and intentions and they

go on to another test or sequence. After the day’s work, the CA submits the non-

compliance reports to the Contractor for signature, if required. A copy is

provided to the Sub and CA. The Sub corrects the deficiency, signs the statement

of correction at the bottom of the non-compliance form certifying that the

equipment is ready to be retested and sends it back to the CA.

2) The CA reschedules the test and the test is repeated.

b. If there is a dispute about a deficiency, regarding whether it is a deficiency or who is

responsible:

1) The deficiency shall be documented on the non-compliance form with the Sub’s

response and a copy given to the GC and to the Sub representative assumed to be

responsible.

2) Resolutions are made at the lowest management level possible. Other parties are

brought into the discussions as needed. Final interpretive authority is with the

A/E.

3) The CA documents the resolution process.

4) Once the interpretation and resolution have been decided, the appropriate party

corrects the deficiency, signs the statement of correction on the non-compliance

form and provides it to the CA. The CA reschedules the test and the test is

repeated until satisfactory performance is achieved.

5. Cost of Retesting.

a. The cost to retest a prefunctional or functional test, if the Contractor is responsible for

the deficiency, shall be born by the Contractor.

b. For a deficiency identified, not related to any prefunctional checklist or start-up fault,

the following shall apply: The CA will direct the retesting of the equipment once at no

“charge” to the GC for their time. However, the CA’s time for a second retest will be

charged to the GC, who may choose to recover costs from the responsible Sub.

c. The time for the CA to direct any retesting required because a specific prefunctional

checklist or start-up test item, reported to have been successfully completed, but

determined during functional testing to be faulty, will be backcharged to the

Contractor,.

d. Refer to the sampling section of 019113, Part 3.6 for requirements for testing and

retesting identical equipment.

6. The Contractor shall respond in writing to the CA at least as often as commissioning

meetings are being scheduled concerning the status of each apparent outstanding discrepancy

identified during commissioning. Discussion shall cover explanations of any disagreements

and proposals for their resolution.

7. The CA retains the original non-conformance forms until the end of the project.

8. Any required retesting by any contractor shall not be considered a justified reason for a claim

of delay or for a time extension by the prime contractor.

C. Failure Due to Manufacturer Defect. If 10%, or three, whichever is greater, of identical pieces

(size alone does not constitute a difference) of equipment fail to perform to the Contract


(BID #2205-18)



Documents (mechanically or substantively) due to manufacturing defect, not allowing it to meet its

submitted performance spec, all identical units may be considered unacceptable by the A/E. In

such case, the Contractor shall provide the A/E with the following:

a. Within one week of notification from the A/E, the Contractor or manufacturer’s

representative shall examine all other identical units making a record of the findings. The

findings shall be provided to the A/E within two weeks of the original notice.

b. Within two weeks of the original notification, the Contractor or manufacturer shall provide a

signed and dated, written explanation of the problem, cause of failures, etc. and all proposed

solutions which shall include full equipment submittals. The proposed solutions shall not

significantly exceed the specification requirements of the original installation.

c. The A/E will determine whether a replacement of all identical units or a repair is acceptable.

d. Two examples of the proposed solution will be installed by the Contractor and the CA will

test the installations for up to one week, upon which the A/E will decide whether to accept

the solution. The Contractor will be responsible for the cost of such testing.

e. Upon acceptance, the Contractor and/or manufacturer shall replace or repair all identical

items, at their expense and extend the warranty accordingly, if the original equipment

warranty had begun. The replacement/repair work shall proceed with reasonable speed

beginning within one week from when parts can be obtained.

D. Approval. The CA notes each satisfactorily demonstrated function on the test form. Formal

approval of the functional test is made later after review by the CA, if necessary. The CA

recommends acceptance of each test to the A/E using a standard form. The A/E gives final

approval on each test using the same form, providing a signed copy to the CA and the Contractor.

3.8. OPERATION AND MAINTENANCE MANUALS

A. Standard O&M Manuals.

1. The specific content and format requirements for the standard O&M manuals are detailed in

Section 017823. Special requirements for the controls contractor and TAB contractor are

found Section 230800

2. CA Review and Approval. Prior to substantial completion, the CA shall review the O&M

manuals, documentation and redline as-builds for systems that were commissioned and to

verify compliance with the Specifications. The CA will communicate deficiencies in the

manuals to the, PM or A/E, as requested. Upon a successful review of the corrections, the

CA recommends approval and acceptance of these sections of the O&M manuals to the PM

or A/E. The CA also reviews each equipment warranty and verifies that all requirements to

keep the warranty valid are clearly stated. This work does not supersede the A/E’s review of

the O&M manuals according to the A/E’s contract.

B. Commissioning Record in O&M Manuals.

1. The CA is responsible to compile, organize and index the following commissioning data by

equipment into labeled, indexed and tabbed, three-ring binders and deliver it to the

Contractor, to be included with the O&M manuals. Three copies of the manuals will be

provided. The format of the manuals shall be:

Tab I-1 Commissioning Plan

Tab I-2 Final Commissioning Report (see (B.2) below)


(BID #2205-18)

Tab 02 System Type 2......repeat as per System 1

2. Final Report Details. The final commissioning 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 in the following areas: 1) Equipment meeting the equipment

specifications, 2) Equipment installation, 3) Functional performance and efficiency, 4)

Equipment documentation and design intent, and 5) Operator training. All outstanding non-

compliance items shall be specifically listed. Recommendations for improvement to

equipment or operations, future actions, commissioning process changes, etc. shall also be

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.

3. Other documentation will be retained by the CA.

3.9 TRAINING OF OWNER PERSONNEL

A. The Contractor shall be responsible for training coordination and scheduling and ultimately for

ensuring that training is completed.

B. The CA shall be responsible for overseeing and approving the content and adequacy of the training

of Owner personnel for commissioned equipment.

1. The CA shall interview the facility manager and lead engineer to determine the special needs

and areas where training will be most valuable. The Owner and CA shall decide how rigorous

the training should be for each piece of commissioned equipment. The CA shall communicate

the results to the Subs and vendors who have training responsibilities.

2. In addition to these general requirements, the specific training requirements of Owner

personnel by Subs and vendors is specified in Divisions 23 and 26. .

3. Each Sub and vendor responsible for training will submit a written training plan to the CA for

review and approval prior to training. The plan will cover the following elements:

a. Equipment (included in training)

b. Intended audience

c. Location of training

d. Objectives

e. Subjects covered (description, duration of discussion, special methods, etc.)


(BID #2205-18)



f. Duration of training on each subject

g. Instructor for each subject

h. Methods (classroom lecture, video, site walk-through, actual operational

demonstrations, written handouts, etc.)

i. Instructor and qualifications

4. For the primary HVAC equipment, the Controls Contractor shall provide a short discussion

of the control of the equipment during the mechanical or electrical training conducted by

others.

5. The CA develops an overall training plan and coordinates and schedules, with the Contractor,

the overall training for the commissioned systems. The CA develops criteria for determining

that the training was satisfactorily completed, including attending some of the training, etc.

The CA recommends approval of the training to the A/E using a standard form. The PM also

signs the approval form.

6. At one of the training sessions, the CA will give a presentation discussing the use of the blank

functional test forms for re-commissioning equipment.

7. Video taping of the training sessions will be provided by the CA with tapes cataloged by the

CA and added to the O&M manuals.

8. The mechanical design engineer shall at the first training session present the overall system

design concept and the design concept of each equipment section. This presentation shall

include a review of all systems using the simplified system schematics (one-line drawings).

3.10 DEFERRED TESTING

A. Unforeseen Deferred Tests. If any check or test cannot be completed due to the building structure,

required occupancy condition or other deficiency, execution of checklists and functional testing

may be delayed upon approval of the A/E. These tests will be conducted in the same manner as

the seasonal tests as soon as possible. Services of necessary parties will be negotiated.

B. Seasonal Testing. During the warranty period, seasonal testing (tests delayed until weather

conditions are closer to the system’s design) of heating or refrigeration equipment shall be

completed as part of this contract. The CA shall coordinate this activity. Tests will be executed,

documented and deficiencies corrected by the appropriate Subs, with facilities staff and the CA

witnessing. Any final adjustments to the O&M manuals and as-builds due to the testing will be

made.

3.11 WRITTEN WORK PRODUCTS

A. The commissioning process generates a number of written work products described in various

parts of the Specifications. The Commissioning Plan—Construction Phase, lists all the formal

written work products, describes briefly their contents, who is responsible to create them, their due

dates, who receives and approves them and the location of the specification to create them. In
