Cx Field Report 002 - 10/14/2011

Cx Activity & General Progress

  • Reviewed status of Unit Checks (Installation and Start-Up Checks).
    • No change to Cx forms but start-up matrix being used by GGCxM to indicate what has been checked out. Click here to review progress.
    • Received mfg. start-up report on Altherma.
    • Received revised test and balance report for air and water systems.
      • Report indicates deficiencies in airflow on booster fan.
      • All fan wheels were adjusted to get proper air gap on wheel assembly. This changes capacity that fan delivers.
      • Expert Mechanical assisted GGCxM to confirm new airflows and find voltage settings on variable speed control to obtain correct volumes.
    • Check for mfg. start-up reports on major equipment (ERV, fans).
  • Continued Technical Integration Testing (System Verification).
    • Sensor testing and back-checking of Cx issues that have been resolved is nearing completion.
    • Refer to sensor and device checkout sheet for items that require repair or adjustment, items that are missing, or requests for clarification.
    • Completed point-to-point checks on all dampers.
    • Tested all modes of ventilation operation.


Cx Issues Update

  • Please see linked documents for Cx Issues found.
    • Cx Issues Log (sorted by Status) is a short summary of issues in PDF format for tracking purposes with active items listed first.
    • Cx Issues is the full description of issues in PDF for record purposes.
    • Cx Issues Resolutions is an interactive Google Docs version of the issues with space for the resolution to be recorded along with name and date of responsible party taking care of the issue. Yellow highlights indicate spaces that should be completed as issues are completed or as questions get answered. Please feel free to put updates in this document that describe what will be done, but only add name and date when issue is truly physically resolved. Access to the document will be coordinated through J. Gallagher.


Next Steps

  • Note: Dates and responsible parties to be confirmed by Construction Manager.
  • Receive manufacturer's check/test/start documentation for ERV, booster fan, and earth room fan. (Expert Mechanical)
  • Verify Unit Testing (Installation & Start-Up Checks) on x. (GGCxA Team)

Look Ahead

  • Prioritize basic cooling testing before weather too cold and so transition to heating mass thermal storage can begin to occur.
  • Need to understand plan for system/equipment alarms - priority, where alarm routed to, what action is required when alarm received (messaging).
  • Need to understand trending capabilities and when it will be available to perform System Level Testing (functional performance testing).
  • Schedule submission of O&Ms manuals for review - completeness, specific to project.
  • Substantial completion and warranty start date - coordinate with warranty review session scheduling.
