ABSTRACT

This paper deals with the Economic End of Life Indicator (EELI). This indicator was developed at Rijkswaterstaat as an indicator for the "end of life" of objects. It is defined as the ratio between:

the life-cycle costs of maintaining a structure and replacing in a statistically expected replacement year

the life-cycle costs of direct replacement and subsequent maintenance.

If this ratio approaches the value of 1, then maintaining becomes less profitable compared to replacement, and it makes sense to assess the functional aspects to evaluate whether replacement may be more beneficial. The EELI can be calculated on the fly as part of an Asset Management System, if all necessary information is available. The EELI is a simple, powerful tool to assess the economical end of life for structures. This paper describes how the EELI works, and how it is used at Rijkswaterstaat.
