See below for details on our commissioning services offered.

Our commissioning expertise includes new equipment installations, retro-commissioning of equipment for performance and benchmark testing, and retro-commissioning of existing equipment for annual maintenance programs or equipment upgrades and repairs. These services improve resiliency for critical systems and provide functional validation of non-standard system designs. Our staff is uniquely trained to physically perform many of the tests required by commissioning plans and specifications.

CXT Engineering’s commissioning team works with the operations and testing team to guide the maintenance and operations support of commissioned facilities. This collaboration produces a full life-cycle engineering perspective for our clients. These perspectives extend beyond construction close-out and on through facility operation and decommissioning, providing our clients with support throughout their entire process and implementation.

Data Center Commissioning & Testing Service Levels

Level 1: Factory Witness Testing

• This tests the equipment within the facility. Data Center builders outline what is expected of the equipment when purchasing the equipment and the factory witness testing ensures that the equipment is performing to the requirements of the end user and industry standards.

Level 2: Site Acceptance Inspection

• Once the equipment is on site, it is inspected by the commissioning agent. This is to ensure that the equipment brought to the site meets the end user’s specifications before it enters the facility.

Level 3: Pre-Functional Testing

• This is the inspection of the installation of the equipment only. The builder and commissioning agency work together to determine if the equipment was installed correctly and is in compliance with industry requirements and regulations. This is also the first time the equipment is turned over and checked for functionality.

Level 4: Functional Performance Testing

• This is additional testing of equipment to ensure that is working as designed and that the fault systems are properly integrating.

Level 5: Integrated Systems Testing (IST)

• The final tests that include all systems working together as designed. Numerous tests will occur to create a comprehensive test routine and is added into the Operations & Maintenance Manuals (O&M).
