Planned Preventative Maintenance ("PPM") is the scheduled maintenance of plant and equipment to ensure that the equipment is operating correctly and to therefore avoid any unscheduled breakdown and downtime. PPM is pre-programmed with maintenance being undertaken for every items separately according to manufacturer's recommendation or legislation.

The primary goal of PPM is for the equipment to make it from one planned service to the next planned service without any failures caused by fatigue, neglect or normal wear and prevent failure before it actually occurs which Planned Maintenance and Condition Based Maintenance help to achieve. It is designed to preserve and restore equipment reliability by replacing worn components before they fail. Maintenance activities include partial or complete overhauls at specified periods, oil changes, lubrication, minor adjustments and so on. In addition, workers can record equipment deterioration so they know to replace or repair worn parts before they cause system failure. The ideal machine maintenance program would prevent any unnecessary and costly repairs. 

 

PPM has advantages over reactive maintenance in that easier planning of maintenance and ordering spares and costs are distributed more evenly. 

Analytics is an overlay to the building controls that allows for the detailed interrogation of the plant and controls functions. The building is monitored and over a short time, discrepancies in operations are flagged for investigations by others. This will identify operational issues that inspection during normal maintenance may not pick up or detect.

Machine maintenance for various equipment and facilities is quite nuanced. For instance, maintaining certain equipment may include a "preventive maintenance checklist" which includes small checks that can significantly extend service life. Furthermore, other considerations such as weather and equipment are taken into account. In the case of HVAC systems, maintenance is often performed before the hottest time of the year.
