3. Construction Phase

The construction phase continues the commissioning authorities responsiblity to verify that the owner's project requirements (OPR) are being achieved.  At this point in the project, the commissioning authority will have finished updating the OPR to reflect any changes approved by the owner.  The OPR and contract design documents will mirror each other ensuring the contractors have the information they need to build a facility fully capable of meeting the owner's needs.
Commissioning tasks during the construction phase typically include all or some of the following.
  • Assist in Pre-Bid
  • Lead Commissioning Team
  • Submittal Review
  • Create Pre-functional Checksheet Templates
  • Develop Functional Performance Tests
  • Direct Testing
  • Verify Training and Systems Manuals
As always, the owner's tolerance for risk will dictate which activities will be included in the commissioning process.  All of the tasks listed above limit the owner's risk to some degree and the owner will have to decide which set of activities provide the level of risk they are willing to accept. 
If the project has been setup to achieve a LEED rating, commissioning is required.  However, there are two levels of commissioning that include a prerequisite (required) level and the Enhanced Commissioning for an extra LEED point.  Each has a different combination of required tasks with Enhanced more closely reflecting the American Society of Heating Refrigeration and Air Conditioning Engineers (ASHRAE) standards for the full commissioning process.
