SECTION 019100 - BUILDING SYSTEMS COMMISSIONING

PART 1 - GENERAL

1.1 DESCRIPTION

A. Commissioning this project shall include MEP systems installation and operations. The commissioning process shall generally follow the ASHRAE Guideline 0 and ASHRAE Std 90.1 I- P. Commissioning for this project shall be as necessary for full compliance with 2021 IECC commissioning requirements.

B. Commissioning Agent (CA): The owner will engage the CA under separate contract.

C. Mechanical and plumbing commissioning shall be done by the registered design professional or approved agency.

D. For electrical commissioning, the registered design professional shall provide evidence that the system is operating in accordance with the construction documents.

E. Commissioning: Commissioning is a systematic process of ensuring that all building systems perform interactively according to the design intent and the owner's operational requirements. Commissioning during the construction phase is intended to achieve the following specific objectives according to the Contract Documents:

1. Observe and document equipment and systems installations and operations.

2. Observe and document proper performance of equipment and systems per the construction documents.

3. Review systems manual and closeout documentation.

F. 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, equipment, or system.

G. Abbreviations: The following are common abbreviations used in the specifications and in the Commissioning Plan.

A/E Architect & Design Engineers FT Functional Performance Test CA/CxA Commissioning Agent GC General Contractor

H. Divisional specifications sections related to commissioning activities are as follows:

1. Division 01 - General Requirements

2. Division 22 - Plumbing

3. Division 23 - HVAC&R

4. Division 26 - Electrical

1.2 COORDINATION

A. Commissioning Team: The members of the commissioning team consist of the Commissioning Agent (CA), the owner’s Project Manager (PM), the designated representative of the owner’s Construction Management firm (CM), 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 report directly to the Owner for commissioning related functions and copy the Architect and Contractor as required. The CA directs and coordinates the commissioning activities and reports with the CM and PM. All team members work together to fulfill their contracted responsibilities and meet the objectives of the Contract Documents.

C. Scheduling: The CA will work with the CM and GC according to established protocols to schedule the commissioning activities. The CM will notify the CA as to the readiness of systems and equipment for functional testing. The CA will provide sufficient notice to the CM and GC for scheduling commissioning activities for such equipment and systems upon notification from the CM that said systems will be ready for testing and or commissioning.

The GC will integrate all commissioning activities into the master project schedule and will provide a copy of the schedule, including all updates, to the CA for his use in commissioning this project. All parties will address scheduling problems and make necessary notifications in a timely manner in order to expedite the commissioning process. It is understood that the progress for commissioning of systems will be dependent upon the progress of the following:

1. Response Times: Timelines for delivering information requested, required, or providing responses to the CA are essential to providing the construction product to the owner on time as well as facilitating the commissioning process. The contractor shall adhere to the following to meet this objective:

a. Written response to Issue Log, Punchlist, Site Observation report, or request for information, clarification, or other documentation necessary to facilitate and carry out the commissioning process: 07 Calendar days from the date request was received by contractor in writing.

b. Discrepancies identified in record drawings during the construction phase: 15 calendar days.

1.3 COMMISSIONING PROCESS

Longview, Tx. 75604 3 5/2/2025 EMA Engineering & Consulting

A. Commissioning Plan: The Commissioning Plan provides guidance in the execution of the commissioning process. The CA will update the plan which is then considered the “final” plan, though it will continue to evolve and expand and be updated on a regular basis for content by the CA 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.

C. Equipment documentation is submitted to the CA during normal submittals and concurrent with the design team submittal submission, including detailed start-up procedures.

D. In general, the check-out and performance verification proceeds from simple to complex;

from component level to equipment to systems and intersystem levels with CHECKLISTS being completed before functional testing.

E. The Subs, under their own direction, execute and document the CHECKLISTS and perform start-up and initial check-out.

F. The checklist procedures are executed by the contractor responsible for their respective systems and under their respective scope of work. An example of a coordinated procedure would be an AHU that requires Electrical, FA Duct Smoke Detector, DDC Controls, and a VFD for operation. This would require a signature from the Mechanical, Electrical, Fire Alarm, Controls contractor, and TAB sub.

G. Functional Testing of the MEP SYSTEMS shall be scheduled by the CA and GC and shall be conducted by the appropriate sub-contractor. The CA will direct the testing and sub-contractor will carry out the test.

H. Items of non-compliance in material, installation, or setup are corrected and the system is to be retested at the contractor’s expense.

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

J. Commissioning is completed before Substantial Completion.

K. Deferred or seasonal testing is to be conducted as specified and as required.
