Commissioning (Cx) is a crucial phase in the construction process, ensuring that all systems — design, installation, testing, operation, and maintenance — meet the owner's specifications. This meticulous process involves thorough review and verification to guarantee efficient and effective building operations.
Commissioning Managers Josh Natale and Preston Sartain provide insight into the commissioning process in the architectural, engineering, and construction (AEC) industry.
The importance of building commissioning
Building commissioning plays a vital role in ensuring not only the seamless and efficient operation of systems, but also the safety of occupants. It involves a comprehensive assessment and testing of mechanical, electrical, and plumbing (MEP) systems to validate their functionality and performance.
From HVAC systems to controls, every component undergoes rigorous testing and validation to meet design specifications and operational requirements. This approach enhances energy efficiency and mitigates potential hazards and operational disruptions post-occupancy.
"When mechanical, electrical, and life safety systems are commissioned properly, we can verify that these systems are installed correctly and will operate as designed," Preston said.
Types of building commissioning services
A comprehensive commissioning approach covers every phase of the process, ensuring buildings operate at peak efficiency and comply with industry standards.
Pre-commissioning review
Ensures the project complies with all codes and industry standards by thoroughly analyzing documentation to align design and construction with specific codes.
Building automation system (BAS) review
Utilizes advanced automation to optimize facility performance, particularly in HVAC integration and specialized controls.
Construction support
Provides hands-on guidance during construction, including site observations and issue resolution, to maintain stringent standards.
Field installation
Ensures equipment installations meet exact standards through comprehensive field testing before occupancy.
Functional and operational performance testing
Implements rigorous protocols to confirm flawless system operation from day one, minimizing post-occupancy issues.
The building commissioning process
Every construction project requires custom building commissioning to ensure excellence in the final product. Minimum repeatable processes and standards are in place to ensure quality installation, often outlined in contract requirements. Unique or unfamiliar systems receive extra attention.
The Cx deliverables provided to a client ensure they are prepared upon building turnover. These deliverables may include:
"Commissioning is a planned and organized approach to placing systems into service by qualified personnel participating as a team. During the design phase various reviews are performed, schedules are planned, and logic is established to match the project," Josh said.
"During construction we eventually move from a static phase to the dynamic state where equipment is started, checks and tests are performed, schedules are realigned with reality, and performance is verified. Afterwards the project is transitioned into a completed state with ongoing warranty commitments, and often long-term monitoring and verification with retro commissioning, maintenance, and additional work as needed," he continued.
Benefits of building commissioning services
Building commissioning services offer numerous benefits that significantly enhance building performance, energy efficiency, and compliance, including:
Building and equipment performance
Building commissioning identifies inefficiencies and opportunities for improvement, reducing energy consumption and utility costs while promoting sustainability.
Sustainability
By optimizing energy usage and minimizing environmental impact, commissioning supports sustainable building practices and aligns with global sustainability goals.
Regulation compliance
Adhering to industry standards and regulations, as outlined by organizations like the National Environmental Balancing Bureau (NEBB), helps avoid penalties and ensures legal compliance.
Streamlined owner transition
Building commissioning supports a smooth transition from construction to operation, ensuring the owner is prepared for the next project phase with quality installations and equipment.
Design improvement
Commissioning professionals often identify design issues that can be addressed to improve future projects, benefiting manufacturers, contractors, and owners alike.
"When the various MEP systems are commissioned, we provide our clients with a proven system that they can have faith in," Preston said.
Building commissioning is an essential aspect of the construction process going beyond verifying systems — it ensures that every component of a building functions as intended, aligning with the owner's vision and regulatory standards. Through comprehensive testing, expert oversight, and meticulous documentation, commissioning not only enhances the performance and efficiency of building systems, but also contributes to sustainability and occupant safety.
