A theoretical model for optimum project (time) performance based on European best practice

Abstract

The authors have over recent years performed extensive empirical research into European (UK, French and German) construction contractor performance. This paper represents the culmination of that research, by presenting a model for achieving optimum project time performance based on European best practice. By removing or neutralizing the impact of external factors (e.g. procurement method), the research concentrated on contractor practices and their direct impact on construction time performance. A variety of European contractor performance data were analysed to identify optimum solutions (i.e. contractors� construction practices) for achieving fastest project completion. The principal theme of the paper is graphical presentation and description of a theoretical model for optimum project (time) performance based on European best practice. Further, characteristics of UK, French and German variants of the model are presented. The application of multiple regression analysis to the data suggests that there are other factors, not embraced by the model, that may also impact significantly upon construction time performance. European contractors and clients may wish to consider the characteristics of these model(s) in striving to achieve earliest project completion.
