Beyond Economic Repair (BER)

An asset is considered beyond economic repair when it is more cost-effective to replace the asset than it is to repair it.  

BER forms one of the later stages in a deterioration model, occurring after potential failure ("P)" has been established but before functional failure ("F) of an asset.


Identification of BER

BER is defined when the density of deficiencies or significance of deficiencies has exceed a  threshold and renders repair uneconomical compared to replacement. 



Attributes of BER
Listed below are some of the key attributes of BER:

Action Strategies upon BER
Listed below are some of the key strategies to consider once BER is established
  • Run to Failure - In some cases it may be appropriate to let the asset run to failure. 
  • Adjust the Maintenance mix to increase the CbM to TbM ratios
  • Implement a preventive replacement program
Attempts at a repair would likely only be satisfactory as a band-aid interim solution.

BER therefore forms part of a compelling argument to be made for a policy of preventive replacement rather than failure replacement of assets. It is important to recognize that there are non-economic reasons that drive the replacement of assets, such as safety, legal and aesthetic.


Evaluation
Listed below are some of the limitations of BER as a concept:
  • BER is not always simple to calculate.
