This paper was published in GE’s January/February 1993.
In the May 1987 edition of Ground Engineering (Cole, 1987) the author presented “A strategy for engineering decisions on treatment” under the same general heading as above. Included in that paper was a table reproduced here as Figure 1, setting down risks by ratios (or orders) of 10 against the three subjects (or ‘fields’) of life, property and money, when considering ‘total loss’nly.
It was suggested that similar tables could be drawn up for ‘partial loss’, ‘impairment’ and ‘inconvenience’, and these are presented in this paper, see Figures 4 and 5. Impairment is damage causing weakening or loss of function. Inconvenience is lack of ease or comfort, or state of awkwardness or troublesomeness.
This paper was originally published in Ground Engineering December 1992.Some of the figures were incorrectly reproduced. We are therefore printing the corrected version in full.
