Maintenance and repair of mechanical hard facilities systems
Overview
This standard is about planning and completing a range of planned and reactive maintenance and modification/repair work across industrial and commercial mechanical Hard Facilities systems to ensure they continue to operate to their design specification. This includes heating, ventilating, hot and cold water supplies, soil/waste (effluent discharge) drainage systems and sanitary components.
The standard requires a high level of individual autonomy, highly developed diagnostic skills and detailed knowledge of system operating principles.
The standard is relevant to engineers and technicians who undertake maintenance, repair and modifications to Building Services Engineering Hard Facilities systems.
