This section covers the Contractor's responsibilities for commissioning; each subcontractor or <br /> installer responsible for the installation of a particular system or equipment item to be <br /> commissioned is responsible for the commissioning activities relating to that system or equipment <br /> item. <br /> C. The Commissioning Authority(CA)directs and coordinates all commissioning activities and <br /> provides Prefunctional Checklists and Functional Test Procedures for Contractor's use. <br /> D. The following HVAC equipment is to be commissioned, including commissioning activities for the <br /> following specific items: <br /> 1. Control system. <br /> 2. Existing VRF system. <br /> 3. DOAS unit <br /> 4. Exhaust fan <br /> 5. Piping systems and equipment. <br /> 6. Ductwork and accessories. <br /> 7. Other equipment and systems explicitly identified elsewhere in Contract Documents as <br /> requiring commissioning. <br /> E. The Prefunctional Checklist and Functional Test requirements specified in this section are in <br /> addition to, not a substitute for, inspection or testing specified in other sections. <br /> 1.02 REFERENCE STANDARDS <br /> A.

System name. <br /> 2. List of devices. <br /> 3. Step-by-step procedures for testing each controller after installation, including: <br /> a. Process of verifying proper hardware and wiring installation. <br /> b. Process of downloading programs to local controllers and verifying that they are <br /> addressed correctly. <br /> c. Process of performing operational checks of each controlled component. <br /> d. Plan and process for calibrating valve and damper actuators and all sensors. <br /> e. Description of the expected field adjustments for transmitters, controllers and control <br /> actuators should control responses fall outside of expected values. <br /> 4. Copy of proposed log and field checkout sheets to be used to document the process; include <br /> space for initial and final read values during calibration of each point and space to specifically <br /> indicate when a sensor or controller has "passed" and is operating within the contract <br /> parameters. <br /> 5. Description of the instrumentation required for testing. <br /> 6. Indicate what tests on what systems should be completed prior to TAB using the control <br /> system for TAB work.
