Obsolescence Management (Revitalization)

The means, methods and techniques for identifying, quantifying, and mitigating against the effects of different types of obsolescence through adaptive renewals.


Nuanced Concepts - Revitalize vs. Modernize?
  • obsolescence vs, 
  • modernization vs. 
  • revitalization
  • upgrade
  • Adaptation
  • Qualitative vs. quantitative
  • "Times are changing"
  • "We need to push our facility to the next level"

Types of Obsolescence
Separate from physical deterioration, the five primary type of obsolescence are identified as follows:

Obsolescence can also be classified in a variety of other ways, including:
  • External obsolescence vs. internal obsolescence
  • Curable obsolescence vs. incurable obsolescence.


Causes of Obsolescence

Obsolescence can arises as a result of a variety of factors impacting upon individual assets and facilities. Some common forces of retirement are listed below:
  • Physical aging
  • New codes and standards (legal obsolescence)
  • Changing demographics
  • Changing needs of the space users (functional obsolescence)
  • New products introduced to the market (technological obsolescence and economic obsolescence)
  • Changing cultural norms and values
  • Planned obsolescence


Impacts on Different Sectors
Included below is a brief outline of some of the ways obsolescence impacts the different sectors.
  • Residential Sector - legal obsolescence
  • Care Sector - legal obsolescence
  • Commercial Sector
  • Hospitality Sector - style obsolescence
  • Civic Sector
Some sectors are more susceptible than others. The following chart lists the sectors, starting with those that are most susceptible:



Methodology

Measuring Obsolescence - FPAs, etc
Included below are some of the primary method for establishing:


Assessing Obsolescence - KPIs, etc
Listed below are some of the Key Performance Indicators that can be used to establish different degrees of obsolescence:

Obsolescence Management by System





Obsolescence Management by Lifecycle

The five general lifecycle stages of facilities can be identified as follows:



Techniques for Mitigation
Listed below are some of the techniques for mitigation of obsolescence on a facility
  • Adaptation - Adaptive renewals
  • Retrofits
  • Modernization
  • Revitalization - to make a facility active, healthy, or energetic again. Revitalization” is an exercise that extends far beyond facility renewal measures

    including the principles and concepts of:



    Principles
    • Short life, medium life and long-life assets


    Adaptive Renewal (Retrofit) Projects
    Listed below are some examples of retrofits (Adaptive Renewals) that form part of the obsolescence management program:

    Replacement Policies
    Listed below are some of the primary replacement strategies that can be applied to different types of assets.

          Group 1: Preventive Replacement        Group 2: Failure Replacement: The relative merits and limitations of each of these policies is discussed in more details on their respective pages in this online glossary.



    Major Strategies
    Included below are some of the asset management principles to consider.
    • "Push the facility to the next level". Times are changing
