Lucko, G; Vorster, M C and Anderson-Cook, C M (2007) Unknown element of owning costs-impact of residual value. Journal of Construction Engineering and Management, 133(1), pp. 3-9. ISSN 0733-9364
Abstract
Residual value is a largely unknown element within the cost calculations for construction equipment that equipment managers are preparing. Traditional estimation methods fall short of capturing its actual nature over time in detail. In this paper we consider the current state of knowledge on residual value and on other cost elements for used heavy construction equipment as implemented in a spreadsheet tool for owning and operating cost calculation. The potential influence of the factor residual value on the total owning costs, and ultimately on total hourly rates, is examined for several different types of heavy equipment. Representative examples of cost calculations are used to perform a sensitivity analysis. Intuitive contour diagrams of the total hourly cost are introduced. The need for an extended examination of residual value of construction equipment is demonstrated using statistical tests. Residual value is found to have a statistically significant contribution to the total hourly cost.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
