    Section(s) for such item and/or in accordance with the manufacturer's written

    recommendations, the Contract Documents, and the Commissioning Plan.

    C. Contractor shall operate each component device and each building system to the full extent

    of its capability, from minimum to maximum, and under automatic control and manual

    control.

    D. Contractor and manufacturer's representatives shall supervise and coordinate adjustments

    and balancing of all devices and systems for proper operation prior to requesting the

    Functional Performance Test(s).

    E. Sampling: [AE shall create a list of electrical system equipment with the appropriate

    FPT’s to check the capacity of the building central systems and initially optimize system

    settings. This will typically be done using the preheat system to false load the cooling

    system. This test will incorporate varying the load to check central systems response.

    W. “Crash Testing”: Contractor shall analyze systems to identify possible conditions where

    functionality may be compromised. Contractor shall design non-destructive tests that will

    demonstrate either the automated response to the conditions or so that team can identify the

    best method for responding or fixing the condition. All tests and their findings shall be

    documented in a Microsoft Excel spreadsheet.

    3.05 PARTICIPATION

    A. Required participating parties are indicated with the individual tests. Typically, multiple

    parties are required for any given test, yet participation for any given party is only required

    for the respective portion of the test for which the party is responsible. In many cases, the

    maximum required time in hours is indicated in parenthesis for any given test. The time is

    typically per unit system unless indicated otherwise. If no time is indicated, participation is

    required throughout the entire test.

    B. Frequently, on multiple samples where a given party does not directly conduct the test, the

    participation of that party will only be required for an initial quantity of systems/equipment. It

    is required that the parties be available on-site throughout the testing of any given system for

    which they are required participants. Therefore time for which they are not directly involved

    can be spent performing other work (typically addressing identified punch list items or failed

    test).

    C. No party involved with the Project is prohibited from participation in or witnessing of any

    tests. Any Subcontractor may elect to witness all tests on their systems even if their

    involvement is not directly required.
