Owners hiring Commissioning providers are typically contracting with an independent third-party verification team that complements and enhances contractor quality assurance and quality control processes, creating comprehensive performance verification that protects all project stakeholders. While Catalyst often plays the role as Owners Commissioning Provider, Catalyst also often contracts with the contractor to support the project’s QAQC requirements. However, it’s not often that we are working for both the owner and contractor simultaneously. This has helped Catalyst develop collaborative relationships with other Commissioning Firms that also provide both of these functions.
Contractor QA/QC focuses on ensuring work complies with contract documents, specifications, drawings, codes, and standards. Contractors verify materials meet specifications, installations follow drawings, workmanship meets quality standards, and testing confirms readiness for functional testing. This internal quality process protects contractors from defect claims, rework, and ensures deliverable quality. Catalyst Commissioning Group provides technical staff to construction managers, contractors, sub-contractors, manufacturers, and integrators to augment their QAQC staff.
Contractors will further augment their QAQC team with added commissioning support responsibilities requiring verification that goes beyond QA/QC compliance checking to test integrated system performance under operational conditions. This helps the contractor team prepare for the Owner’s Commissioning Provider and their requirements at a later phase in the project. While QA/QC verifies a valve was installed correctly, commissioning support verifies the valve operates correctly under available control sequences. While QA/QC confirms ductwork meets specifications, commissioning support works with the testing and balancing contractor to verify the entire air distribution system delivers proper airflow to all zones under varying conditions.
The relationship creates comprehensive verification:
• Installation verification: QA/QC inspects physical installation; commissioning witnesses installation at critical stages and verifies completeness.
• Startup verification: QA/QC performs manufacturer-recommended startup; commissioning observes startup and verifies procedures were followed correctly.
• Pre-functional verification: Commissioning support helps contractors to complete detailed pre-functional checklists confirming equipment readiness for testing, a QA/QC extension ensuring thorough preparation.
• Functional performance verification: Commissioning support prepares the contractors’ installations for rigorous functional testing, demonstrating systems perform as designed under various conditions. QA/QC builds the foundation for reliable functional performance testing.
• Integration verification: QA/QC addresses individual system components; commissioning support verifies systems work together properly, HVAC integrating with controls, controls integrating with BAS, and mechanical coordinating with electrical.
• Documentation verification: QA/QC produces installation documentation; commissioning support verifies documentation availability, accuracy and completeness, identifying gaps requiring correction.
Benefits for contractors:
• Early problem and rework identification when corrections are simpler and less expensive
• Reduced callback risk through thorough verification before owner acceptance
• Documentation protecting against future claims
• Third-party validation of quality workmanship
• Clear acceptance criteria preventing subjective disputes
• Training ensuring operators understand systems, reducing improper operation claims
Benefits for owners:
• Independent verification providing confidence beyond contractor self-inspection
• Comprehensive testing ensuring systems perform as promised
• Documentation supporting warranty claims and operations
• Reduced risk of accepting deficient work
When contracted to an owner, Catalyst Commissioning services do not replace contractor QA/QC. The contractor is still required to provide validation that QA/QC processes were effective and systems actually perform as intended through internal or independently sourced QAQC services.
Catalyst Commissioning Group is constantly on demand by contractors for Commissioning Support and QAQC services (when owners have contracted their own separate commissioning provider).
