Procurement type and quality in infrastructure projects
(English)Manuscript (preprint) (Other academic)
One of the major goals of any project is to achieve the highest possible quality level without adversely affecting the anticipated cost and schedule. The final quality of a project is determined by a number of factors and there is no simple deterministic relation between these underlying factors and the level of quality. A fundamental question is whether quality can be increased by choosing a particular procurement method or the risk for low quality is higher with certain procurement method. Despite the existence of large literature in this area, there has not been clearly formulated that quality is independent from the choice of procurement type. We argue that given the right conditions all procurement methods can give good results, and given the wrong conditions all of them can lead to low quality.
The aim of this paper is to try to synthesize both theoretical and empirical results about the performance of different procurement method and present arguments that make this statement convincing. The theoretical framework used in this paper is general contract theory and transaction cost theory while the result from questionnaire carried out within the project provided important empirical background.
Two questions that are central to the debate of the choice of procurement method in relation to quality of the final project are who should do the detailed design and should construction and operations be bundled. A client with low technical competence may choose design-build procurement method as the client then only has to specify the characteristics of final product. This same client can also contact with technical consultant and make the detailed design together that would allow client to use design-bid-build procurement method. The main conclusion is that there is no quick fix when it comes to improving quality in infrastructure projects and there is no a procurement method that guarantees a better quality than another.
