DocuSign Envelope ID: 9826C043- 4C32- 49CD- A4CC- DC28ABAB7CE7 <br />SECTION 238000 — TEST AND BALANCE <br />B. Special Guarantee: Provide a guarantee on NEBB forms stating that NEBB will assist in completing <br />requirements of the Contract Documents if TAB firm fails to comply with the Contract Documents. <br />Guarantee shall include the following provisions: <br />1. The certified TAB firm has tested and balanced systems according to the Contract <br />Documents. <br />2. Systems are balanced to optimum performance capabilities within design and installation <br />limits. <br />C. Adjustments: For one year after Owner occupancy, provide the services of a qualified TAB <br />technician upon request of the Designer to take readings and make adjustments as necessary and <br />directed by Designer for comfort conditions. <br />PART 2 - PRODUCTS/VENDORS <br />2.1 ACCEPTABLE TAB CONTRACTORS <br />A. The following TAB agents are acceptable to Owner and Designer for providing TAB services: <br />1. Palmetto Air and Water Balance, Inc. (Asheville, Charlotte, Raleigh NC and Greenville, SC) <br />2. Watts Services (Morganton, NC) <br />3. Hall Technology, Inc. (Leesville, SC) <br />4. Test and Balance Corporation (Winston - Salem, NC) <br />5. The Phoenix Agency (Winston - Salem, NC) <br />B. The Designer will consider other TAB agents as acceptable under the following conditions: <br />1. Request to consider another TAB agent is received from a Prime Bidder or HVAC Contractor <br />intending to bid the project. <br />2. Request to consider another TAB agent is submitted at least 10 days prior to receipt of bids. <br />3. Proposed TAB agent is certified per this specification. <br />4. Approval for a proposed TAB agent to bid the project will be communicated via Addendum <br />prior to receipt of bids. <br />PART 3 - EXECUTION <br />3.1 EXAMINATION <br />A. Examine the Contract Documents to become familiar with Project requirements and to discover <br />conditions in systems' designs that may preclude proper TAB of systems and equipment. <br />1. Verify that balancing devices, such as test ports, gage cocks, thermometer wells, flow - control <br />devices, balancing valves and fittings, and manual volume dampers, are required by the <br />Contract Documents. Verify that quantities and locations of these balancing devices are <br />accessible and appropriate for effective balancing and for efficient system and equipment <br />operation. <br />B. Examine approved submittal data of HVAC systems and equipment. <br />C. Examine Project Record Documents described in Division 01 Section "Project Record Documents." <br />D. Examine design data, including HVAC system descriptions, statements of design assumptions for <br />environmental conditions and systems' output, and statements of philosophies and assumptions <br />about HVAC system and equipment controls. <br />E. Examine equipment performance data including fan and pump curves. Relate performance data to <br />Project conditions and requirements, including system effects that can create undesired or <br />unpredicted conditions that cause reduced capacities in all or part of a system. Calculate system <br />effect factors to reduce performance ratings of HVAC equipment when installed under conditions <br />different from those presented when the equipment was performance tested at the factory. To <br />calculate system effects for air systems, use tables and charts found in AMCA 201, "Fans and <br />Systems," Sections 7 through 10; or in SMACNA's "HVAC Systems - -Duct Design," Sections 5 and 6. <br />Compare this data with the design data and installed conditions. <br />F. Examine system and equipment installations to verify that they are complete and that testing, <br />cleaning, adjusting, and commissioning specified in individual Sections have been performed. <br />G. Examine system and equipment test reports. <br />H. Examine HVAC system and equipment installations to verify that indicated balancing devices, such <br />as test ports, gage cocks, thermometer wells, flow - control devices, balancing valves and fittings, and <br />manual volume dampers, are properly installed, and that their locations are accessible and <br />appropriate for effective balancing and for efficient system and equipment operation. <br />I. Examine systems for functional deficiencies that cannot be corrected by adjusting and balancing. <br />J. Examine HVAC equipment to ensure that clean filters have been installed, bearings are greased, <br />belts are aligned and tight, and equipment with functioning controls is ready for operation. <br />K. Examine terminal units, such as variable- air - volume boxes, to verify that they are accessible and <br />their controls are connected and functioning. <br />L. Examine plenum ceilings used for supply air to verify that they are airtight. Verify that pipe <br />penetrations and other holes are sealed. <br />M. Examine strainers for clean screens and proper perforations. <br />N. Examine three -way valves for proper installation for their intended function of diverting or mixing fluid <br />flows. <br />O. Examine heat - transfer coils for correct piping connections and for clean and straight fins. <br />P. Examine system pumps to ensure absence of entrained air in the suction piping. <br />Reece, Noland & McElrath, Inc. 238000-2 Orange County Board of Elections <br />Orange Co., NC 05/04/18 <br />
