Field studies in construction equipment economics and productivity

Earthmoving and construction equipment have evolved significantly during the past century. During the same time, our ability to study and understand equipment economics and productivity has also gained significant ground. This paper relates some of the recent academic research to industry practices. In doing so, it validates some parts of the research and makes new observations in three areas: repair costs, residual values, and total cost of ownership (TCO) and productivity. It also provides a few pointers for future research.
