Preventive Maintenance Plan
Playing a key role in facilities management, preventative maintenance serves to ensure regular
functionality and sustainability of an establishment through regular and routine scheduling of
maintenance activities. The main objective of an effective preventive maintenance plan is to
prolong the lifetime of equipment and assets as well as preventing equipment failure or reducing
potential downtime. Typical equipment included in a preventive maintenance plan include the
following:
1. Genset engine (“Diesel engine”) – A “genset”, also referred to as a generator set, is a
reliable solution providing portable power as well as a reliable source of energy if there is
none. Genset engines are a key component of business continuity and serve to protect
commercial interests by restoring normal power when the main electrical supply is
disrupted due to bad weather, a blackout or scheduled maintenance. These engines
operate by converting chemical energy from fuel (diesel) into mechanical energy which is
then converted into electricity by means of other equipment. To ensure that it performs
when needed, regular inspections are implemented. Maintenance actions, such as
cleaning or replacing parts is done as needed or by supplier recommendations.
2. Genset generator – To generate electricity gensets require the use of an alternator to
convert mechanical energy into electrical energy. To maintain a seamless transition from
the main power supply to a genset engine, the use of equipment such as a system control
panel and transfer switch is utilized. This also serves to reduce downtime as the generator
does not require human intervention to commence operation. Regular servicing of these
electrical equipment is necessary but for the most part consists of inspection for leaks and
signs of corrosion. Maintenance will also include in regular observations of performance,
recording data and carrying out tasks such as replacing minor parts based on operating
hours, schedule or as needed.
3. HVAC – An important aspect of any establishment involves the heating, ventilation and
air-conditioning or HVAC system. HVAC systems are responsible for maintaining
occupancy comfort through the regulation of heat, airflow, and air quality in any
building. This includes the air-handling (indoor) units, condensing (outdoor units), the
exhaust fans, grilles, and louvers. As HVAC equipment are required to operate for most
of the day and in many cases, constantly (24/7), it is necessary to schedule regular
maintenance. A routine preventive maintenance not only prolongs the life of the HVAC
equipment but also improves its efficiency, thus reducing operating costs. Another added
benefit is improved air quality and occupancy comfort.
4. Fire pump – Much like generators, fire pumps operate as part of an emergency system
and are triggered by an unwanted event. In the event of a fire, the fire protection system
engages to quickly dispatch the danger. To carry this out in an efficient manner, the
system needs to maintain a consistent water pressure and volume, which is achieved with
the use of a fire pump. As such, there is a need for this equipment to be readily available
and when needed, perform without fault. In this case a preventive maintenance plan
would prove to be a worthy asset. Activities such as routine inspection for leaks and
changes in pump performance.
5. Water pumps – Whether it is utilized for a potable water supply or to work in conjunction
with other equipment (HVAC – Chilled water systems), water pumps play an important
role in providing a consistent water flow rate and supply. In larger buildings this is
necessary as the pipe length as well as height will result in a loss of flow. With the use of
VFD technology, modern water pumps can efficiently pump water to various sections of
a building while maintaining pressure. Similar to HVAC, as this equipment runs
consistently, routine inspection and maintenance as per the supplier recommendations is
strongly advised.
Preventive Maintenance Tools / Corrective Action
1. Common tools and equipment used to carry out preventive maintenance:

Multimeter – Ammeter, ohmmeter, voltmeter

Terminal screwdriver, screwdrivers, and nut drivers

Pliers

Labelling machine

Measuring devices – Tape measure, level, pressure gauge, temperature gauge.

Power drill

Power washer

Refrigerant recovery machine

Wet/dry vacuum

Air compressor

PPE – Safety glasses, steel toe shoes, dust mask etc.
2. Similar to how the plan was created an excel document would be utilized to record and
report data recorded from periodic (daily, weekly, and monthly) maintenance activities.
Given its flexibility and practicality, the data could be used and presented in numerous
ways. Specific dates, readings and tasks can be recorded, and filtered according to
various elements.
3. Corrective action
a) Fuel leak from Genset – To correct a fuel leak, one must first stop any operation
of the equipment. Secondly, minimize hazard by placing a suitable container to
catch any fluid. The source of the leak should then be identified through visual
inspection. Depending on the location, the equipment manual can be used to
identify the correct course of action to remedy issue whether to repair, replace
part or to tighten joint.
b) Pipe water leak from pump connection - To correct a fuel leak, one must first stop
any operation of the equipment. Upon identifying the source of the leak through
visual inspection, the equipment manual can then be used to identify the correct
course of action to remedy issue whether to repair, replace part or to tighten joint,
packing, gaskets, or O-ring.
c) Vibration on pump motor – To correct vibration, one would first consult the
Installation and Operations Manual to troubleshoot issue. As noise and vibration
is generated by the revolutions of the pump motor, it can be assumed that the
issue is isolated to that location. Following the procedure provided in the IOM,
one can narrow the issue down to, misalignment, failure in support, failure in
vibration damper etc. and correct as needed.
Safety Training
A vital component of any work environment is safety. A safe and flourishing workplace serves to
protect its workers from injury and illness as well as increase productivity, efficiency, and
employee satisfaction. For positions with high risk, a well thought out and successful training
program is to be implemented. Under facilities management, groundskeeping is not only
important but is of high risk as it consists of a wide range of maintenance, and landscaping tasks.
If important safety guidelines are not followed this may result in bodily injury and/or illness. It is
therefore imperative that the following considerations are taken when carrying out these tasks.
1. Personal Protective Equipment (PPE) – For any employee working with safety hazards it
is important to be informed of the appropriate PPE for the relevant tasks. This includes
protection for the head, face, eyes, ears, body, and feet. This can be outlined in an
informative presentation followed by a demonstration.
2. Chemical Hazard Awareness – As chemicals are utilized in cleaning, maintenance, and
gardening tasks, it is important to be informed of the responsibilities, storage, and
handling procedures, and first aid treatment. The employee can be educated on how to
read the safety data sheets, chemical labels and where to easily locate information. This
can be outlined in a presentation along with provided brochures.
3. Electrical Equipment and Machine Safety – As groundskeepers may work around hazard
areas as well as with machinery, it is key that the employee is trained on how to approach
possibly dangerous situations. Hazards such as electrical shock and mechanical harm may
be caused in such environments. A presentation, demonstration and tour of the facility
would be valuable in this case.
4. Tool Safety – In many instances groundskeepers may employ the utilization of tools as
well as small to large machinery (from power drills to lawnmowers) to assist in carrying
out general maintenance tasks. As such, appropriate procedures and demonstrations must
be done to properly educate employees on how to handle such equipment. This can be
outlined in a presentation and demonstration session.
5. Assessment – Following the presentations, demonstrations, and overall tour of the facility
(approximately 6 hours), the groundskeeper can then be subjected to an assessment of
whether he/she has retained such information and is ready to carry out such duties.
