Section 3:
CARETAKER MAINTENANCE
General. As stated in para. 1.3.2, caretaker maintenance refers to
3.1
the level of maintenance performed on an inactivated facility to preserve its
weathertightness, security, and protection from fire, rodents, birds, or human
damage. Caretaker maintenance also includes performing those tasks necessary
to keep an inactivated facility aesthetically acceptable when it is located
among other active facilities.
The process for maintaining an inactive facility is the same as for
maintaining an active facility, only the degree and frequency of task
execution may be different. All relevant Navy instructions and publications,
such as NAVFAC MO-321, Facilities Management; MO-322; and OPNAVINST 11010.34B
Instructions for Preparation and Submission of the Type "A" Annual Inspection
Summary and Narrative Assessment, still apply. The cyclical sequence of
inspection and maintenance procedures must still be followed. NAVFAC's
philosophy of controlled maintenance still applies. This section relates the
various maintenance and inspection procedures to caretaker efforts.
Types of Maintenance Actions
3.1.1
Preventive Maintenance. This category involves the day-to-day
3.1.1.1
effort required to keep a facility, piece of equipment, or system functioning.
The intent is to reduce downtime by anticipating problems and taking necessary
actions to prevent them. Preventive maintenance actions are usually low cost,
have little impact of activity resources, and are performed by operators,
rather than maintenance personnel.
3.1.1.2
Corrective Maintenance. Corrective maintenance involves the
planned replacement of material or components that have worn or failed,
thereby causing a degradation of a system or facility to operate at full
capacity. This category involves maintenance efforts that are more involved
than preventive maintenance and are usually accomplished by maintenance
technicians.
3.1.1.3
Breakdown Maintenance. Breakdown maintenance is necessary when an
unplanned building or system failure occurs. It is the most costly type to
perform because it cannot be routinely planned. Maintenance personnel must
react to breakdown situations immediately, interrupting other planned work.
Also, proper spare parts or other materials may not be readily available,
causing a need to substitute less adequate material or cannibalize some other
system.
Borrowing. In the normal maintenance of active facilities, there
3.1.1.4
is a tendency to "borrow" parts or components from buildings or facilities in
an inactive status. This "borrowing" or `cannibalization" appears prudent at
the time since it saves the time required to obtain the parts from normal
channels. The intent is always to reorder and eventually replace the borrowed
