Mechanical Contractor shall be responsible for complete system start-up prior to testing, adjusting, and balancing and shall demonstrate operation of each item of mechanical equipment. 2. Motor amp draw shall be checked and adjusted to within 80% of rated amp draw during start-up procedures on all motors. Replace drive packages as necessary to achieve design conditions. 3. Set return air velocity to 500 fpm at each air unit inlet during start-up procedures. 4. Attend pre-balancing conference with testing agency to demonstrate operation of system. 5. Install clean filters in all air units. 6. Verify that systems are complete and operable. Refer to Part 3, Paragraph 3.1A. 7. Cooperate with Testing and Balancing Agency to provide all necessary data on the design and proper application of the system components and furnish all labor and material required to eliminate any deficiencies or malperformance. Resolve all operational deficiencies prior to submission of final TAB report. 8. Install all valves, dampers, sheaves, and miscellaneous adjustment devices in a manner that will leave them accessible and readily adjustable. The TAB Agency may be consulted if there is a questionable arrangement of a control or adjustable device. 9. Cooperate with Commissioning Provider to provide all necessary assistance in demonstration and operation of all HVAC system components. Provide test reports as required by Commissioning Provider for functional performance testing. B. Responsibility of Testing, Adjusting and Balancing Agency (TAB): 1. During construction, inspect the installation of ductwork, Facility Management System and all other components of the HVAC system. Inspection will cover that part of the work relating to proper arrangement and adequate provisions for the testing and balancing. The inspections shall be performed periodically as the work progresses with a minimum of two inspections as follows: a. When 60% of ductwork is installed in each building. b. When 90% of ductwork is installed in each building. 2. Submit brief written report of each inspection to Owner, Architect, Engineer, and Contractor. 3. Provide all instruments and equipment required to accomplish necessary testing, adjusting, and balancing and as required by the Engineer to verify performance. All instruments shall be in accurate calibration and shall be calibrated in ranges that will be expected. 4. Field verify equipment nameplate electrical data. Do not derive data from submittal documents. 5. Upon completion of the installation and start-up of the mechanical equipment by the Mechanical Division, the Testing, Adjusting and Balancing Agency will test, adjust, and balance the system components to obtain optimum conditions in each conditioned space in the facility. TAB Agency shall work with the Automatic Temperature Controls Contractor in commissioning the operation of all motorized/balancing duty control dampers. The TAB Agency is advised that deficiencies in HVAC construction are often encountered during final TAB services and Agency should include in bid proposal an amount it deems adequate to compensate for time in identifying the deficiencies to the Mechanical Contractor and awaiting their correction. 6. As soon as possible or a minimum of fourteen days, or earlier, prior to Owner's Final Inspection as requested by the General Contractor, the Testing and Balancing Agency shall prepare seven copies of the completed Testing and Balancing Report and submit one copy to Owner and six copies to the Architect/Engineer. The reports shall be certified accurate and complete by a principal Engineer of the Agency. Resolve all operational deficiencies prior to submission of final report. 7. Cooperate with Commissioning Provider to provide all necessary assistance in demonstration and operation of all HVAC system components. Provide test reports as required by Commissioning Provider for functional performance testing. 8. Commissioning: a. Refer to Specification Section 20 00 10 for commissioning plan and commissioning requirements. b. Cooperate with Commissioning Provider to provide all necessary assistance in demonstration and operation of all HVAC system components. Provide test reports as required by Commissioning Provider for functional performance testing.
