Orange County West Campus Office Building -HVAC PDC Project 23020 General Commissioning Requirements 01 91 13 - 5 1.If difficulty in correction would delay progress,report deficiency to the Commissioning Authority immediately. 3.05 FUNCTIONAL TESTS A.A Functional Test is required for each item of equipment,system,or other assembly specified to be commissioned,unless sampling of multiple identical or near-identical units is allowed by the final test procedures. B.Contractor is responsible for execution of required Functional Tests,after completion of Prefunctional Checklist and before closeout. C.Commissioning Authority is responsible for witnessing and reporting results of Functional Tests, including preparation and completion of forms for that purpose. D.Contractor is responsible for correction of deficiencies and re-testing at no extra cost to Owner;if a deficiency is not corrected and re-tested immediately,the Commissioning Authority will document the deficiency and the Contractor's stated intentions regarding correction. 1.Deficiencies are any condition in the installation or function of a component,piece of equipment or system that is not in compliance with Contract Documents or does not perform properly. 2.When the deficiency has been corrected,the Contractor completes the form certifying that the item is ready to be re-tested and returns the form to the Commissioning Authority;the Commissioning Authority will reschedule the test and the Contractor shall re-test. 3.Identical or Near-Identical Items: If 10 percent,or three,whichever is greater,of identical or near-identical items fail to perform due to material or manufacturing defect,all items will be considered defective;provide a proposal for correction within 2 weeks after notification of defect,including provision for testing sample installations prior to replacement of all items. 4.Contractor shall bear the cost of Owner and Commissioning Authority personnel time witnessing re-testing. 5.Contractor shall bear the cost of Owner and Commissioning Authority personnel time witnessing re-testing if the test failed due to failure to execute the relevant Prefunctional Checklist correctly;if the test failed for reasons that would not have been identified in the Prefunctional Checklist process,Contractor shall bear the cost of the second and subsequent re-tests. E.Functional Test Procedures: 1.Some test procedures are included in Contract Documents;where Functional Test procedures are not included in Contract Documents,test procedures will be determined by the Commissioning Authority with input by and coordination with Contractor. 2.Examples of Functional Testing: a.Test the dynamic function and operation of equipment and systems (rather than just components)using manual (direct observation)or monitoring methods under full operation (e.g.,the chiller pump is tested interactively with the chiller functions to see if the pump ramps up and down to maintain the differential pressure setpoint). b.Systems are tested under various modes,such as during low cooling or heating loads, high loads,component failures,unoccupied,varying outside air temperatures,fire alarm, power failure,etc. c.Systems are run through all the HVAC control system’s sequences of operation and components are verified to be responding as the sequence's state. d.Traditional air or water test and balancing (TAB)is not Functional Testing;spot checking of TAB by demonstration to the Commissioning Authority is Functional Testing. 3.PECI (Samples)found at http://www.peci.org/library/mcpgs.htm indicated anticipated level of detail for Functional Tests. F.Deferred Functional Tests: Some tests may need to be performed later,after substantial completion,due to partial occupancy,equipment,seasonal requirements,design or other site conditions;performance of these tests remains the Contractor's responsibility regardless of timing. 3.06 SENSOR AND ACTUATOR CALIBRATION Docusign Envelope ID: 8DED1454-68D2-4E36-9FC6-E56FF2124E5D
