New Construction Commissioning: NC-Cx

Commissioning is a quality focused process for enhancing the delivery of a project. The process focuses on verifying and documenting that the facility and all of its systems and assemblies are planned, designed, installed, tested, operated and maintained to meet the Owner's Project Requirements (OPR).

Step 1: Pre-Design Commissioning

  • Pro-MEC assists in the development of the Owner’s Project Requirements (OPR) and the Basis of Design (BOD). As your Commissioning Authority, Pro-MEC insures clarity of both documents and consistency between them.
  • OPR – Completed by the Owner, Commissioning Authority (Cx-A), and Project Team. The OPR compiles the communication and documentation of –
    • Owner and User requirements
    • Environmental and sustainable goals
    • Energy efficiency goals
    • Indoor Environmental Quality requirements (IEQ)
    • Equipment and System expectations
    • Building occupant and O&M personnel requirements
  • BOD – Completed by the Design team – a narrative description proposing how the OPR will be achieved –
    • Primary design assumptions
    • Standards
  • Draft initial Commissioning Plan
    Pro-MEC creates the Project Commissioning Team with you, collaborating to draft the Commissioning Plan with the intent to describe the scope of commissioning, the schedule for commissioning activities, propose initial commissioning field checklist formats and highlight potential format for Owner training.

Step 2: Design Commissioning

  • Review Design documents for compliance with BOD/OPR
  • Review mechanical submittals and begin entering data into Construction Phase commissioning checklists
  • Meet with TAB and Controls Contractor
    Review prints and verify presence/location of balancing devices; gather all applicable TAB certification materials, draft of TAB plan, and review potential scheduling of TAB/control system operation for coordination of system startup, TAB and FPT.

Step 3: Construction Commissioning

  • Modify Commissioning Plan prior to construction phase commissioning activities
    Review initial draft of Commissioning Plan and update as applicable to include any added items
  • Review construction for compliance with BOD/OPR and contract documents, applicable submittal review
  • Pre-installation Verification (PIV)
    A verification of equipment as it is delivered. These "off the truck" checks are intended to verify that the correct equipment has been delivered, is correctly tagged and is not damaged upon receipt.
    Additionally, methods of onsite storage are reviewed.
  • The forms and which equipment they apply should be included in the bid pack for the contractor review prior to bidding
  • A copy of all PIV forms is placed on the jobsite for the contractor to complete
  • As your Commissioning Authority (Cx-A), Pro-MEC follows-up on a random assortment of these verifications; if found to be falsified and/or non-compliant in excess of a pre-stated percentage, these verifications will be corrected and re-checked by contract
  • Pre-Startup Verification (PSV)
    PSV is a verification of all installed systems for compliance to plans and specification. Each type of inspection form is described in detail as part of the Commissioning Plan.
  • The forms and which equipment they apply to is included in the bid pack for the contractor to review prior to bidding
  • A copy of all PSV forms is placed on the jobsite for the contractor to complete
  • As your Commissioning Authority (Cx-A), Pro-MEC follows-up on a random assortment of these verifications; if found to be falsified and/or non-compliant in excess of a pre-stated percentage, these verifications will be corrected and re-checked by contractor
  • Startup Testing and Verification (STV)
    STV tests verify proper start-up of all equipment and systems
  • The forms and which equipment they apply to is included in the bid pack for the contractor to review prior to bidding
  • A copy of all STV forms and requirements is placed on the jobsite for the contractor to complete
  • As your Cx-A, Pro-MEC follows-up on a random assortment of these tests; if found to be falsified and/or non-compliant in excess of a pre-stated percentage, these verifications will be re-checked by contractor

Step 4: Acceptance Commissioning

  • Functional Performance Testing (FPT)
    FPT tests verify that all systems are functioning and interacting with other systems correctly
  • These procedures are included in the bid pack for the contractor to review prior to bidding
  • A copy of all FPT requirements is placed on the jobsite for the contractor to view at any time
  • As your Cx-A, Pro-MEC carries-out these tests with the Controls contractor; if found to be non-compliant in any manner, the issue will be resolved and the FPT will be re-started until full compliance is attained with respect to the intended sequence of operation
  • Operator and Owner Training
    Pro-MEC aids in the preparation and administration of an owner training seminar. The seminar covers operation and maintenance of each piece of equipment and system. Each vendor and contractor shall provide training in the applicable area of responsibility. Typically, this is a mix of classroom and on-site training with the system in operation. We try to video tape the entire event for re-use and training of new employees. Training will be conducted by the design engineers, the equipment vendors, the Cx-A, and any/all contractors as originally specified in the project at hand.
  • Commissioning Report
    As your Cx-A, Pro-MEC compiles a complete Cx report. The report includes all Commissioning check sheets for the design phase, PIV, PSV, STV and FTP tests and observations. Also to be included will be all Cx documentation and correspondence. The report contains a complete operating narrative for each system explaining the sequence of operation for each function.

Step 5: Warranty Commissioning

  • Deferred or Off-Season Testing
    As your Cx-A, Pro-MEC and appropriate contractors provide an off season FPT for the HVAC system. The test covers the ability of the system to maintain control setpoint during the opposite season from the original Cx season. Pro-MEC as Cx-A provides a post-Off-Season Cx report. This completes the New Building Commissioning process (NB-Cx). Pro-MEC provides a final Cx report, featuring an operational review.
