Old Age (50 years and Beyond)

The five lifecycle stages of buildings are identified as follows:

The 5th life stage of a building starts at about 50 years.  

It is important to note that there is no direct correlation between the age and the condition of a building. Some older building can be in very good condition as a result of the owners having replaced the assets at the ends of their useful service lives. Similarly, some young buildings may be in poor condition due to inadequate maintenance or premature failure of some assets. 

Project planning in this life phase is generally back-end loaded.

Decisions will arise as to the relative merits of continued reinvestment or redevelopment.

Renewal Projects
Listed below are some of the long-life assets that are sometimes renewed during this stage in the life of a facility:

  • Cladding assemblies
  • Glazing assemblies
  • Transformers
  • Sanitary and stormwater collection.
Functional obsolescence sometimes drives adaptation of non-residential facilities during this life stage.

Most buildings will continue to operate for many decades beyond life cycle 5. The necessary and sufficient maintenance during each life stage, coupled with timely renewal of assets, will ensure that the owners receive many decades of good value from their real estate investment.



Attributes
Buildings in the old age lifecycle stage tend to have the following attributes
