Commissioning ( Cx ) Management Services

According to CIBSE [1], “the commissioning programmers produced by building services installers and their sub-contractors are frequently over-optimistic and uncoordinated. They assume that others will co-operate in providing water, gas and electric supplies, a weather tight building, unobstructed access and a dust-free environment. A risk of project overrun will exist unless the interdependencies of all the building services systems and plant are identified, together with their integration with on-going construction activities. This complex, and highly fragmented part of the construction process demands good management”. FAC can provide indepandent commissioning management consultancy services.

Benefits of Commissioning Management

Building Energy Systems Commissioning
To verify that the project’s energy-related systems are installed, and calibrated to perform according to the owner’s project requirements ( OPR ), basis of design ( BOD ) and construction documents. Benefits of commissioning include reduced energy use, low operating costs, fewer contractor callbacks, better building documentation, improved occupant productivity and verification that the systems perform in accordance with the owner’s project requirements ( OPR ).

Data Center Commissioning
Due to the enormous investments in the equipment they house, and the essential nature of the information they process, data centre require highly reliable electromechanical systems for electricity supply, space conditioning, fire protection and security.
In order to operate effectively, banks and other financial services companies require reliable communications, data processing and data storage facilities. Major equipment is often housed in dedicated data centres, where 99.9% reliability is not an uncommon requirement.

Heat Load Test (HLT) and Integrated Systems Test (IST)
The data centre is to form a key part of global network for IT, as such any failure and inadequate performance of the cooling capacity would be a major incident for client. To overcome any happening of failure incident or inadequate cooling capacity, elements of the plant and systems should have backups to ensure uninterrupted use of the facility.

To ensure operation of these mission critical systems in emergency or failure, FAC could be appointed as commissioning managers to manage the various stages of commissioning, interdependency testing, heat load test ( HLT ) and the Integrated Systems Test ( IST ).

Heat Load Test (HLT)
The HLT is to test the entire cooling system for the data centre taking into account of the failure and different cooling loadings requirements by simulating corresponding heat loadings provided by electrical heaters at the data hall.

Integrated Systems Test (IST)
The IST is to test the reliability of the E&M system for data centre. By simulating failures at different scenarios and observe the corresponding response of the equipment and the system. This is particularly important for life safety systems and critical environments.
FAC could lead all parties involved in the preparation and planning of the documentation to be used and ensure that all system failure scenarios are tested, with the system set to operate as intended for normal use.
