SECTION 01 91 13

GENERAL COMMISSIONING (CX) REQUIREMENTS

PART 1 GENERAL

1.1 GENERAL DESCRIPTION

A. Commissioning (Cx) is the process of ensuring that all building systems are installed and perform interactively according to the design intent and meet the Government’s operational needs; that the installation is adequately documented; and that the Operators are adequately trained.

Commissioning helps minimize post-occupancy operational problems and establishes testing and communication protocols that advance the building systems from installation to full operation.

Commissioning plans must be prepared and passed to the GSA for review and approval. This process can take up to 14 calendar days.

B. The specification sections dictate all requirements of the commissioning process relative to the construction contract. The Commissioning Plan outlines the commissioning process. The Contractor shall be responsible for complying with any additional duties or responsibilities contained in the Commissioning Plan that are not otherwise specified in the Contract Documents.

C. Equipment and system start-up is a Contractor responsibility with all equipment tagged with the Individual’s name and date. Contractor shall submit sample tags for GSA approval. Individuals who start the equipment shall provide their name and date. Coordinate with Mechanical Specification 230553 for further tag guidance The GC shall be responsible for all costs incurred by the Government due to the Contractor's failure to perform any of its responsibilities pursuant to this section.

1.8 COMMISSIONING SEQUENCING AND SCHEDULING

A. Commissioning will be categorized into Phases as indicated below. Note that per schedule, different systems and/or areas may be in different phases at any given time given that the Cx and testing process will be integrated into the construction process:

1. Construction Phase Commissioning: This is the period of time where the systems are installed, much of the commissioning documentation is developed, the systems are started, and the majority of the Contractor required training is performed. On any given system or area, the Construction Phase will end when the CxP approves proceeding with the Functional Performance testing.

2. Acceptance Phase Commissioning: This is the period of time where the systems will be functionally tested and the systems will operate through any endurance period.

B. Prior to submission of the baseline schedule, the Contractor will coordinate with the Commissioning Agent (CxP) to specifically include the detailed tasks involved in the commissioning (Cx) process.

Contractor shall incorporate the commissioning tasks for EACH SYSTEM. MEOR shall address any negative pressure conditions. In addition MEOR shall provide testing concepts and various testing conditions for all key systems and components.

C. Contractor shall notify the CxP in writing at least 14 days in advance of any tests, start-ups, or training. CxP shall witness selected tests and start-ups.

1.9 START-UP PROCEDURES AND DOCUMENTATION

A. Equipment and system start-up is a Contractor responsibility. The CxP will selectively witness start-up and will consolidate all the start-up documentation provided by the Contractor. The Contractor will coordinate with the CxP to establish standard processes for witnessing all tests.

B. Mechanical and Electrical Sections 15995 and 16995 specify minimally acceptable Start-up Procedures for a variety of mechanical and electrical systems. Start-up procedures and protocols will differ by manufacturers.

C. Prepare and submit required draft Start-Up Procedures and submit along with the manufacturer’s installation and start-up information. Provide the manufacturers preprinted and standard Start-Up Checklists, forms, and protocols in an acceptable electronic format, both for review early in the construction process and to document the start-up process towards the end of the Construction Phase.

D. GC shall start-up, test, adjust, and balance systems and equipment prior to verification and performance testing by the Commissioning Authority. Provide skilled technicians qualified to do the work required. Provide factory trained/authorized technicians where required by the contract documents and stated in the applicable technical section. Generally, Start-Up and testing shall proceed from device checkout, to component checkout, to system checkout, to interrelated system checkout. Tag equipment that is started with the Individual’s name and date.

E. Completed start-up checklists for all pieces of equipment shall be submitted to CxP prior to any associated functional performance testing. Any outstanding item shall be clearly indicated and an associated action Item must be tracked to resolution.

F. Contractor is responsible for having equipment ready for start up and testing. If CxP is not able to test then the contractor will be responsible for additional costs incurred.

1.10 FUNCTIONAL PERFORMANCE TESTING

A. Functional Performance Testing demonstrates that each system is operating according to the

Contract Documents. Functional Performance Testing facilitates bringing the systems from a state of Substantial Completion to full dynamic operation. Additionally, during the functional testing process, areas of deficient performance are identified and corrected, improving the operation and functioning of the systems.

B. Contractor shall completely install, thoroughly inspect, start-up, test, adjust, and balance systems and equipment. All activities shall be documented per specified procedures and progress tracked on the construction schedule. Contractor shall notify the CM and CxP in writing that systems are complete and ready for verification and functional performance testing.

C. The Contractor will work with the CxP to develop all Functional Performance Testing procedures to ensure feasibility, safety and equipment protection. The Contractor will provide necessary written alarm limits to be used during the tests. Damage caused to equipment performed in accordance with the approved procedures will be the responsibility of the Contractor.

D. The commissioning-related responsibilities of the Contractor during Functional Performance Testing are:

1. Assist CxP in functional performance testing. Assistance will generally include the following:

a. Manipulate systems and equipment to facilitate testing.

b. Provide any specialized instrumentation necessary for functional performance testing

c. Manipulate BAS and other control systems to facilitate functional performance testing.

2. Correct any work not in accordance with Contract Documents.

3. Maintain record documentation, update and resubmit it after Functional Completion.

E. The CxP will record the results of the functional test. All deficiencies or non-conformance issues shall be noted as Action Items and reported to the CM. Corrections of identified minor deficiencies may be made during the tests at the discretion of the CxP and will be documented. If there is a dispute about a deficiency, regarding whether it is a deficiency and/or who is responsible, the issues should be addressed in writing to GSA’s construction manager on site and copied to the project manager and contracting officer.

1.11 TRAINING EVENTS

A. The Contractor shall prepare and conduct training sessions specified in the contract. The CxP will witness the training concerning the installed systems and equipment. The Contractor shall be responsible for ensuring all training is performed in accordance with the Contract Documents.

B. The Contractor shall provide training to Government operators on individual systems and equipment only after successful Start-Up. These training events cover proper operation, maintenance, repair, and diagnosis of the systems, equipment, and components installed by the Contractor.

C. Training shall not be conducted until the system or equipment is operating properly and after it has been successfully started per the commissioning requirements.

D. The Contractor must provide an electronic copy of all documents used in the training sessions and shall provide a list of the names of the attendees.

E. The Contractor shall provide training to Government operators on whole-building operation. The focus is primarily on BAS control of building systems and operation, and its impact on building performance. System interactions shall be presented and discussed (such as a combined air handler, chilled water, boiler, and terminal unit system), along with a detailed presentation of the sequences of operation and their relationship to the BAS. After all individual FPTs have been successfully completed, conduct final whole-building systems operation training.
