Effects of Procurement on Project Performance: a Survey of Swedish Construction Clients

In order to increase the efficiency of the construction industry development and improvement of procurement procedures is vital. The purpose of this investigation is to increase the understanding of how procurement procedures affect project performance. A procurement model including eight hypotheses is first developed on the basis of a literature review and then tested through multivariate statistical techniques based on empirical data collected through a survey investigation of 106 Swedish construction clients. The results of hierarchical regression analyses show that cooperative procurement procedures positively affect collaboration among project actors and that collaboration in turn have positive effects on project performance. In general, however, cooperative procurement procedures do not have direct effects on project performance.
