Round 1 Bowling and Amusement 12/09/2024 Paradigm Design <br />Main Place Mall Expansion Grand Rapids, MI <br />Santa Ana, California <br />Project #2309147GR <br />B.Partial Owner Occupancy: Owner may occupy completed areas of building before Substantial <br />Completion. Cooperate with Owner during TAB operations to minimize conflicts with Owner's <br />operations. <br />1.7 COORDINATION <br />A.Notice: Provide seven days' advance notice for each test. Include scheduled test dates and <br />times. <br />B.Perform TAB after leakage and pressure tests on air and water distribution systems have been <br />satisfactorily completed. <br />PART 2 - PRODUCTS (Not Applicable) <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 />B.Examine systems for installed balancing devices, such as test ports, gage cocks, thermometer <br />wells, flow-control devices, balancing valves and fittings, and manual volume dampers. Verify <br />that locations of these balancing devices are accessible. <br />C.Examine the approved submittals for HVAC systems and equipment. <br />D.Examine design data including HVAC system descriptions, statements of design assumptions <br />for environmental conditions and systems' output, and statements of philosophies and <br />assumptions about HVAC system and equipment controls. <br />E.Examine ceiling plenums and underfloor air plenums used for supply, return, or relief air to <br />verify that they meet the leakage class of connected ducts as specified in Division 23 Section <br />"Metal Ducts" and are properly separated from adjacent areas. Verify that penetrations in <br />plenum walls are sealed and fire-stopped if required. <br />F.Examine equipment performance data including fan and pump curves. <br />1.Relate performance data to Project conditions and requirements, including system effects <br />that can create undesired or unpredicted conditions that cause reduced capacities in all or <br />part of a system. <br />2.Calculate system-effect factors to reduce performance ratings of HVAC equipment when <br />installed under conditions different from the conditions used to rate equipment <br />performance. To calculate system effects for air systems, use tables and charts found in <br />AMCA 201, "Fans and Systems," or in SMACNA's "HVAC Systems - Duct Design." <br />Compare results with the design data and installed conditions. <br />G.Examine system and equipment installations and verify that field quality-control testing, <br />cleaning, and adjusting specified in individual Sections have been performed.
