Maintenance
action of keeping in effective
condition , in working order , in repair ;
deals with the specific procedures,
 The
tasks, instructions, personnel,
qualifications, equipments and resources
needed to satisfy the maintainability req.
within a specific use environment.
{Hudson,Infrastructure Management p.221]
Maintenance
that set of activities required to
keep a component , system,
infrastructure asset, or facility
functioning as it was originally
 Is
designed and constructed to
function

Maintenance
Subset of maintenance :
1. Preventive Maintenance : ( proactive maintenance )
is performed to retard or prevent
failure of a component or system
deterioration or
2. Corrective Maintenance : ( reactive maintenance )
is performed to repair damage and/or to restore
infrastructure facilities to satisfactory operation, or function
after failure
Maintenance
Subset of maintenance :
3. Routine Maintenance :
is any maintenance done on a regular basis or
schedule . It is generally preventative in nature , but may
be corrective.
4. Hard – time Replacement : ( HTR )
is replacement after a certain length of time,
regardless of whether the component has failed or not. It is
therefore a type of routine maintenance , but may also be
corrective or preventive
Maintenance
Subset of maintenance :
5. On-condition Maintenance : ( OCM )
is any maintenance done in response to conditionmonitoring actions indicating impending deterioration or
failure. By definition it is a type of preventive
maintenance
6. Critical maintenance :
is defined by some as the maintenance that must be
done immediately to prevent imminent collapse or
functional failure
Maintenance
Maintenance standards treatments :
1. Preservation
2. Rehabilitation
3. Restoration
4. Reconstruction
Maintenance
Preservation 
the act or process of applying
measures necessary to sustain the
existing form, integrity and materials of
historic property
Maintenance
Restoration
the act or process of accurately
depicting the form, features and
character of property as it appeared at
a particular period of time
Maintenance
Reconstruction 
the act or process of depicting by means
of new construction the form, features
and detailing of a non-surviving site,
landscape, building, structure or object , for
the purpose of replicating its appearance at
a specific period of time and in its historic
location.
Rehabilitation
Rehabilitation :
The act
or process of making possible
a compatible uses for a property through
repair, alterations, and additions , while
preserving those portions or features that
convey its historical , cultural, or architectural
values. [Hudson,Infrastructure Management p.233]
Rehabilitation
Key ideas of Rehabilitation :[Hudson,Infrastructure Management p.233]
1. Use
the property as it was used
historically, or find a new use that
minimize retention of
distinctive features
Rehabilitation
Key ideas of Rehabilitation :[Hudson,Infrastructure Management p.233]
2.
Preserve the historic
character .
Do not make changes that falsify
the historical development
Rehabilitation
Key ideas of Rehabilitation :[Hudson,Infrastructure Management p.233]
3.
Repair deteriorated features.
Replace a severely deteriorated
feature with a matching feature ( eg
substituted materials )

Infrastructure Alternatives
• Infrastructure planning involves multiple ideas
• Infrastructure planning involves multiple tasks
• Infrastructure planning involves the identification of
alternatives
• Infrastructure planning involves the comparison of
alternatives
Infrastructure Alternatives
• Methods for comparing and Prioritizing
[Goodman. Infrastructure Planning Handbook p 6.2]
Simple cost basis :
–
–
–
–
–
–
Construction cost
Investment cost
Annual Cost
Cost per unit of constructed infrastructure
Cost per unit of services or output
Present, future and annual value of a stream of costs
over a specific period of service for an infrastructure
facility
Infrastructure Alternatives
• Methods for comparing and Prioritizing
[Goodman. Infrastructure Planning Handbook p 6.2]
Simple cost basis plus consideration of other
Specified engineering factor , including :
–
–
–
–
Length of useful life
Quality of construction and durability of facilities
Associated problems of maintenance and operation
Susceptibility to unforeseen problems of construction,
maintenance and operation
– Flexibility of facilities for expansion and/or replacement
in the future
Infrastructure Alternatives
• Methods for comparing and Prioritizing
[Goodman. Infrastructure Planning Handbook p 6.2]
Life cycle cost basis ( Present value basis ) :
– Costs only
– Costs offset by savings to beneficiaries of facilities
– Costs offset by savings ang by values of other types of
benefits
Infrastructure Alternatives
• Methods for comparing and Prioritizing
[Goodman. Infrastructure Planning Handbook p 6.2]
Cost basis including adjustment made for
additional screening criteria:
– Adjustment of estimates made by others of cost ,
capacity and output
– Adjustment of estimates made by others to reflect
sponsor’s special requirement
– Adjustment of estimates made by others to reflect
analyses of local and regional infrastructure system
Infrastructure Alternatives
• Methods for comparing and Prioritizing
[Goodman. Infrastructure Planning Handbook p 6.2]
Additional preliminary cost-driven methodologies
for state and local infrastructure system:
– Routine maintenance and replacement decisions
based upon engineering judgments as to a priorities
and the availability of fund
– Analyses based upon cost-effectiveness
– Comparison of alternatives based upon additional
measure of performance incl. effectiveness in
providing services, reliability and cost
Infrastructure Alternatives
• Methods for comparing and Prioritizing
[Goodman. Infrastructure Planning Handbook p 6.2]
Full Financial Analyses:
– Development of arrangements to implement
project, with term and conditions of financing.
– Cost per unit of services product, and
comparison with existing market prices and
with willingness and ability to pay
– Annual years analyses of all monetary input
and output at market prices with inflation
effect and subsidies.
Infrastructure Alternatives
• Methods for comparing and Prioritizing
[Goodman. Infrastructure Planning Handbook p 6.2]
Economic Analyses ( or benefit cost
analyses):
– Year by year analyses off all cost and benefits
in which monetary amounts are in terms of
their economic values
– Extended analyses that consider regional
benefits that are in addition to direct benefits
to users of project services and product
Infrastructure Alternatives
• Methods for comparing and Prioritizing
[Goodman. Infrastructure Planning Handbook p 6.2]
Multi Dimensional Analyses:
– Matrices, account of several categories for
considering multiple attributes of alternatives
– Display techniques that consider broad
multiple objectives
Infrastructure Alternatives
• Methods for comparing and Prioritizing
[Goodman. Infrastructure Planning Handbook p 6.2]
Multi Dimensional Analyses:
– Mathematical model and methods designed to
consider trade-off and produce an optimum
alternative
– Other decision-oriented methodologies such as AI (
Artificial Intelligence) based method or AHP (
Analytical Hierarchy Process )
Infrastructure Alternatives
• Methods for comparing and Prioritizing
[Goodman. Infrastructure Planning Handbook p 6.2]
Special Studies:
– Government agency formal protocol to
perform the planning functions of
identification, preliminary screening of
alternatives
Infrastructure Alternatives
• Methods for comparing and Prioritizing
[Goodman. Infrastructure Planning Handbook p 6.2]
Special Studies:
– Regional simulations and other types of
system analyses having outputs in such
terms as economic impact and/or
degrees of attainment of specified goals
or objectives
