Abstract

In the construction industry, the relationship between clients and contractors has been usually characterized by uncertainty and adversarial behaviour. More recently, their relationship is said to be changing from a traditional and arms-length basis to more collaborative forms, e.g. partnering. There is evidence that such collaborative forms can have a substantial impact on project performance, not only with regard to time, cost and quality objectives, but also with regard to more general outcomes, e.g. greater innovation and improved user satisfaction. However, such benefits are less well understood due to limited research and in particular an absence of robust and appropriate methods of evaluation. The purpose of this research is to address this shortfall and seek to evaluate these wider aspects of project performance relative to different degrees of collaborative working. To achieve this, collaborative working and project performance first need to be transformed into a measurable form by breaking them down into a variety of attributes or indicators. Surrounding these attributes/indicators, item statements are developed and a Likert Scale is then adopted for questionnaire design. Questionnaires were mainly administered by semi-structured interviews in which the client and contractor from the same project were invited to evaluate their collaborative working and the corresponding project performance. After unidimensionality and reliability testing for the composite measures, the response difference between client and contractor group is explored through conducting paired samples t-test. Subsequently, cluster analysis is conducted to produce a taxonomy of collaborative working and correlation and regression analysis are conducted to explore the associations between collaborative working and project performance. The final conclusion strongly supports the existence of a strong positive linear relationship between collaborative working and project performance, provides valuable regression formulas to make project performance predictions and gives a more precise classification of collaborative working to help reduce the confusion over its definitions in a novel way.
