Specifications include, but are not limited to: The work included in the commissioning process shall involve a complete and thorough evaluation of the operation and performance of all equipment and systems installed under this project. Equipment and systems that shall be evaluated include, but are not limited to, the HVAC systems and the Plumbing systems. Documentation required from the Mechanical Contractors, as part of the commissioning process shall include as appropriate the HVAC Systems and Plumbing systems Documentation required from the Mechanical and Plumbing Contractors as part of the commissioning process shall include as appropriate and applicable: Equipment submittals and shop drawings for CxA review. Progress and status reports, including deficiencies noted. Manufacturers' suggested pre-functional checklists for CxA's use in developing pre- functional procedures. Start-up and testing documentation associated with systems being commissioned including but not limited to the following: duct leakage, pipe pressure, electrical testing, flushing / cleaning, etc. Performance (sign-off) of pre-functional checklists documentation. Including completed manufacturer start-up reports. Training agenda and material for CxA's review. Operation and maintenance (O&M) manuals. Pre-functional Checklists, Tests, and Startup: Pre-functional checklists (PC) are important to ensure that the equipment and systems are hooked up and operational and that functional performance testing may proceed without unnecessary delays. Each piece of equipment receives full pre-functional checkout by the Contractor. No sampling strategies are used by the contractor. In general, the pre- functional testing for a given system must be successfully completed prior to formal functional performance testing or equipment or subsystems of the given system. Pre-functional checklists are primarily static inspections and procedures to prepare the equipment or system for initial operation (e.g., oil levels OK, fan belt tension, labels affixed, gages in place, sensor calibration, etc.). However, some pre-functional 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 “pre-functional” refers to before functional testing. Pre- functional checklists augment and may be combined with the manufacturer's start-up checklist. Contractors typically already perform some, if not many, of the pre-functional checklist items the commissioning authority will recommend. This project requires that the procedures be documented in writing by the installing technician where detailed in the project MEP specifications. The CxA does not witness most of the pre-functional check listing, except for testing of larger or more critical pieces of equipment and some spot-checking. It is noted that the checklists generated by the CxA do not take the place of manufacturer or contractor required checklists. The CxA, with assistance as required from the installing contractor, will complete checklists that are generated by the CxA. Commissioning Tests: Detailed testing shall be performed on all installed equipment and systems to ensure that operation and performance conform to contract documents and the design intent. All functional tests shall be witnessed by The Commissioning Agent. The following testing is required as part of the commissioning process: Verification Functional Tests: Verification tests shall be comprised of a full range of checks and tests to determine that all components, equipment, systems, and interfaces between systems operate in accordance with contract documents and the design intent. This shall include all operating modes, interlocks, control responses, and specific responses to abnormal or emergency conditions. Functional Performance Tests: Functional performance tests shall determine that the commissioned systems are operating in accordance with the Contract Documents and the design intent.
