Commissioning

Corporate Data Center

Tier IV Consulting Group was the principal commissioning firm for a large Tier III corporate data center that was constructed in our client’s new World Headquarters building.  The commissioning process followed the guidelines set forth in the ASHRAE Guideline 0.  The commissioning program included review of the Owner’s Project Requirements Document and the Basis of Design Document, a design peer review, a review of all submittals for compliance, input on potential design modifications related to construction cost savings, oversite of factory startup testing and full management and control of integrated testing.  Numerous deficiencies were identified and corrected during the commissioning program that, had they not been identified during construction and commissioning, may have resulted in a failure of the data center.  The owner engaged Tier IV Consulting Group to assist in the development of policies and procedures.  We were also engaged to provide additional training to the onsite facilities staff. 

Corporate Data Center

Tier IV Consulting Group is the principal commissioning firm for a large Tier IV data center that is currently under construction.  This facility will eventually serve as the primary data center for our client.  Our principal role is to oversee the factory startup and individual system commissioning and to perform all integrated testing.  Our integrated commissioning program will include all normal modes of operations.  Where possible, multiple failure modes will be introduced into the system to verify proper system response and notification. 

Annual and Emergency Field Testing

Tier IV Consulting Group is often engaged to conduct component and system level testing in active facilities.  Annual testing programs may include engine generator transient and load testing, UPS System transient and load testing, UPS System Battery load testing and HVAC system and chiller performance validation.  We use the latest test equipment to validate that all systems are operating in accordance with the manufacturer’s specifications and industry standards.  Emergency testing is conducted after there has been a component or system failure.  We often test UPS Systems with artificial load immediately after failed components (inverter or rectifier power transistors, filter capacitors, etc.) have been replaced and prior to returning the critical load to the UPS output.  This test will ensure that the repairs have been properly completed.  It may also identify non-replaced components that may have been stressed but did not fail during the initial event.  This testing provides the owner with a comfort level that his system will operate as designed with critical load connected.
