Long-Life Asset

An asset whose typical service life is longer than 30-years. 


Attributes
Long life assets may have one or more of the following physical and financial attributes:


    Examples
    Some typical examples of long-life assets, sorted by system, are listed below: 

          Enclosure System
    • Masonry cladding assemblies (40+ years)
    • Some glazing systems (30-40 years)
    • Sloped metal roofs
    • Soffits
    • Slab on grade
           Mechanical System
    • Drainage collection systems (50+ years)
           Electrical System
    • Unit substations (35+ years)
    • Transformers (35+ years)
    • Electrical distribution
          Sitework System
    • Asphalt paving (but this may be a borderline medium life asset)
    • Concrete slabs (80+ years)

    Management Principles
    The renewal of long-life assets are contemplated in the strategic planning horizon and are characteristic of projects in the old age life stage of a building.
