Maintenance The action of keeping in effective

condition , in working order , in repair ; deals with the specific procedures, tasks, instructions, personnel, qualifications, equipments and resources needed to satisfy the maintainability req. within a specific use environment. {Hudson,Infrastructure Management p.221]

Maintenance

Is that set of activities required to keep a component , system, infrastructure asset, or facility functioning as it was originally designed and constructed to function [Hudson,Infrastructure Management p.221]

Maintenance

Subset of maintenance : [Hudson,Infrastructure Management p.231] 1. Preventive Maintenance2. Corrective Maintenance 3. Routine Maintenance 4. Hard – time Replacement 5. On-condition Maintenance6. Critical maintenance

Preventive or Proactive Maintenance

On-condition Maintenance

On-condition Maintenance

Hard-TimeReplacement

RoutineMaintenance

MaintenanceSubset of maintenance :

1. Preventive Maintenance : ( proactive maintenance )

is performed to retard or prevent deterioration or failure of a component or system

2. Corrective Maintenance : ( reactive maintenance )

is performed to repair damage and/or to restore infrastructure facilities to satisfactory operation, or

function after failure

MaintenanceSubset 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

MaintenanceSubset of maintenance :

5. On-condition Maintenance : ( OCM )is any maintenance done in response to condition-monitoring 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

MaintenanceMaintenance standards treatments :1.Preservation 2.Rehabilitation3.Restoration4.Reconstruction

MaintenancePreservation

the act or process of applying measures necessary to sustain the existing form, integrity and materials of historic property

MaintenanceRestoration

the act or process of accurately depicting the form, features and character of property as it appeared at a particular period of time

MaintenanceReconstruction

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.

RehabilitationRehabilitation :

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


2. Preserve the historic character . Do not make changes that falsify the historical development

Rehabilitation


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



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



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



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



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.



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



Multi Dimensional Analyses:– Matrices, account of several categories

for considering multiple attributes of alternatives

– Display techniques that consider broad multiple objectives



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 )



Special Studies:– Government agency formal

protocol to perform the planning functions of identification, preliminary screening of alternatives



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
