1 SECTION GENERAL COMMISSIONING REQUIREMENTS GENERAL The University of South Alabama is officially and formally committed to the concept of Commissioning all new buildings and major renovations. This section of the Standard is intended to provide guidance and information regarding the minimum expectations and requirements of the commissioning process at the University. The primary goal of this section is to inform the A/E team of their Commissioning related responsibilities. This section will also detail general Commissioning related responsibilities of various members of the commissioning team. DESCRIPTION OF COMMISSIONING Commissioning (Cx) is a systematic process of insuring that building systems operate and perform according to the owner s project requirements and operational needs. The Commissioning process oversees, verifies and documents that the facility and its systems and assemblies are planned, designed, installed, tested, operated and maintained as required to meet the owner s functional intent and the project contract documents. Specific objectives of commissioning are as follows: Verify that applicable equipment and systems are designed and installed according to the manufacturer s recommendations, to industry accepted minimum standards, and to be safely and adequately accessible for maintenance. Verify and document proper performance of equipment and systems. Verify that O&M documentation submitted is accurate and complete. Verify that the owner s operating personnel are adequately trained. The commissioning process does not take away from or reduce the responsibility of the A/E team or installing contractors to provide a finished and fully functioning product. OWNER'S PROJECT REQUIREMENTS (OPR) Beginning in the early stages of the design phase the Owner, with the architect s assistance, determines the project requirements. The OPR is a written document that details the functional requirements of a project and the expectations of how it will be used and operated. This includes project and design goals, measurable performance criteria, schedules, success criteria, and supporting information. The Owner and architect conduct scoping or programming meetings to develop the OPR. The scoping meetings bring together members of the design team and Owner groups with an interest in the project to document each group s needs. The Owner and architect document the project requirements to establish a baseline of performance expectations to which the actual installed performance is compared. Once approved the OPR in written form is issued by the Owner and A/E Team to the CxA and other project stakeholders. BASIS OF DESIGN (BoD) The OPR provides the explanation of the ideas, concepts and criteria that are considered to be very important to the Owner, resulting from the programming and conceptual design phases. The basis of design is the documentation of the primary though processes and assumptions behind design decisions that were made to meet the design intent. Adequate documentation of the Basis of Design of the energy and comfort related systems in a building are rarely found in bid documents. It is vital, however, that design intent and sequences of operation be documented adequately. That documentation serves as the goal that pre-functional and functional testing seeks to achieve. In addition, the document provides valuable information over the life of the building to the different parties involved in operating, maintaining, and trouble-shooting the building systems. Design documentation is needed from the architect so that the design engineers can design systems and write specifications. Design documentation is needed from the design engineers and architect so that the building contractors and technicians can properly construct the building. Final design documentation is needed from the building contractors and all of the above parties so that the building operator and maintenance contractors can properly maintain the original intent of the systems operations over time.

2 The design documentation evolves from more general descriptors during the conceptual design, to more specific descriptors during actual design, to in-depth and specific descriptors during the specifying stage. The design documentation is completed by fine tuning and adding further detail and specificity for some components during the as-built documentation stage. Though design documentation for some components cannot be completed until the end of building construction, it is not warranted to allow design documentation to be general or incomplete prior to construction. Design documentation should be as firm and complete as possible as early as possible. TIMELINE OF COMMISSIONING For most projects at the University, the Cx process will begin at the beginning of the schematic design phase and continue through and conclude at the end of the first year warranty period. The University will contract directly with the Commissioning Consultant, herein referred to as the Commissioning Authority (CxA). The CxA will be independent of the design and construction teams. The CxA will report to the University Project Manager. The University's Project manager will develop and distribute the Cx Statement of Work (SoW) and Request for Proposal (RFP) for each project. The CxA shall manage the Cx process within the project. COMMISSIONING TEAM The members of the commissioning team shall include the University's Project Manager, the CxA, the architect, the design engineers, the general contractor and/or construction manager, the mechanical contractor, the electrical contractor, the BAS contractor, the TAB contractor, the plumbing contractor, the fire protection contractor and the fire alarm contractor, if different from the electrical contractor. Other members of the Cx Team include the LEED consultant if provided and personnel of the University's ED and C staff. Each Cx Team member shall assign one individual to be the primary point of contact for the commissioning process. COMMISSIONING PROCESS OVERVIEW AND RESPONSIBILITIES DESIGN PHASE The following are general design phase expectations and responsibilities of specific Cx Team members: Owner (University of South Alabama) Produces the Owners' Requirements (OPR) Assign operations and maintenance personnel and schedule them to participate in the various meetings, training sessions, and site observations/inspections. Review and approve any changes made to the Owner's Project requirements. Review and comment on the commissioning authority's Commissioning Cx plan. Provide the CxA the Basis of Design (BoD) for systems being commissioned. Respond to any resulting review questions pertaining to the CxA s review of the BoD. Meet with the CxA to discuss and coordinate the design phase Cx process and review the Cx Plan developed by the CxA. Incorporate into the project specifications the commissioning specifications, and any referenced attachments, provided by the CxA. Coordinate with the CxA which numbering format is being used. Respond to the design review comments provided by the CxA, TAB consultant and BAS Contractor. Provide responses prior to issue of the next progress submittal. The CxA will generally review the following submittals: 100% SD, 100% DD, 50% CD and 95% CD. The TAB consultant will generally review the 50% and 95% CD submittals. The BAS Contractor will generally review the 95% CD submittal. UPDATED - JULY 21, 2017 Page 2 of 7

Note that this list above entails the equipment and systems which fall within the third party commissioning consultants scope of work. Any equipment or systems not listed here does not imply the installing contractor is not obligated to commission his work as required by the project contract documents. USGBC LEED PROGRAM (if required by owner) The CxA SoW will adhere to and generally exceed the USGBC LEED requirements for the following credits, based upon the current version of the rating system: EA Prerequisite 1: Fundamental Commissioning of Building Energy Systems EA Credit 3: Enhanced Commissioning EQ Credit 7.2: Thermal Comfort: Verification FACILITY SHELL COMMISSIONING The Envelope Commissioning Authority (ECx) will be independent of the design and construction teams. The contract with the ECx will generally be held directly by the University, however, this contract can be held by the MEP CxA or the Architect. Consult with the assigned Project Manager and Commissioning Engineer on each project regarding contractual coordination. DESIGN PHASE RESPONSIBILITIES The ECx will review various design phase submittals. Typically, reviews will be done on the 50% and 95% CD submittals. The design reviews will focus primarily on the envelope section details shown in regards to waterproofing and air infiltration. The architect will be expected to work with and meet, as required, with the ECx to discuss review comments. The architect will also be expected to provide written response to each review comment, informing UPDATED - JULY 21, 2017 Page 6 of 7

7 whether the correction was implemented, if more information is required from the reviewer, or if there is a disagreement with the comment. CONSTRUCTION PHASE RESPONSIBILITIES The ECx will be involved in the submittal and shop drawing review process. The architect will be expected to coordinate with the ECx to perform reviews concurrent with the architect reviews. The ECx will conduct pre-construction conference(s) with the envelope construction team. During these conferences, the ECx s submittal and shop drawing review comments will be discussed, along with general coordination and sequence of material installation. The responsible subcontractor will also be expected to provide written response to each review comment, informing whether the correction will be implemented, if more information is required from the reviewer, or if there is a disagreement with the comment. The ECx will conduct periodic site visits during construction to observe below and above grade construction. After each site visit, the ECx will provide an associated field report. The General contractor and the responsible subcontractor will be expected to address any deficiencies identified in the field reports. Written remedial action regarding each identified deficiency will also be expected by the construction team. TESTS During T and B testing, T and B contractor will test 10% of each operational system to verify their operation. The contract documents shall require the contractor to demonstrate water and air tightness on a minimum of 15% of the installed window systems. The contractor will be expected to assist and coordinate with the ECx regarding the level of support required (i.e., man-lifts, water hoses, water, chamber construction, etc.) In general, the ECx will perform to following tests on a representative sample of envelope openings: Nozzle testing per AAMA Static Pressure Chamber testing per ASTME 1105 UPDATED - JULY 21, 2017 Page 7 of 7
