Abstract [en]

Public sector clients play different roles in the provision of transport infrastructure projects. They are responsible to identify the needs of end-users, determine performance objectives of projects and ensure that the most appropriate procurement method that minimizes risks and optimizes outcomes is chosen. Public sector client could also have a major influence on the actions and behavior of other actors in the sector that ultimately improve the overall performance and productivity of construction sector.

The purpose of this paper is to present and argue for a number of statements about what is important in order to improve quality in new infrastructure projects. The paper tries to synthesize both theoretical and empirical results concerning organizational performance, especially the role of client competence for the quality of the project. Results from the questionnaire carried out within the project but presented elsewhere and extensive literature review are mainly utilized.

We argued that knowledge and incentives are two crucial dimensions for getting high quality. The internal process of client organization such as design type, procurement method, and construction procedures could be influenced by client’s internal resource capacity. Thus, a more structured and proper knowledge management will not only minimize the loss of tacit knowledge and enhance public sector’s internal process capacity but will also reduce reliance on specific procurement method without economic and technical justifications. Furthermore, certain strategies such as incentive schemes, second opinion practices, post-review reporting for accountability and transparency purposes could improve public sector’s knowledge assets. It is expected that only a public sector client with skilled and experience workforce supplemented with appropriate knowledge management can succeed to fulfill their societal responsibilities.

Abstract [en]

The performance of the construction industry and its contribution to the welfare of society in comparison to other industries such as the manufacturing industry has lately been the focus of many commissioned reports and academic research publications. The so-called “iron triangle” of time, cost and quality have been the most important metrics of construction project performance, especially for the selection of appropriate procurement methods. The perceived inefficiencies emanate from, among other things, increasing construction costs, conflicts and client dissatisfaction, the fragmented nature of the industry, low competition, cost overruns and delays, and lack of quality improvement. There is observed disparity in increases in housing construction costs and an apparent lack of quality improvement of infrastructure transport projects. In Sweden, metropolitan regions experienced higher construction cost increases, while small regions showed less costs increases during economic booms. In order to address these perceived inefficiencies, numerous strategic and project level decisions that influenced the way that publicly owned properties and projects are procured, constructed, operated, and maintained have been made. The decision to transfer quality-related activities and quality assurance responsibilities from client to contractor approximately 25 years ago is one of the decisions that could have an impact on current quality of infrastructure transport projects. The disparity in increases in construction costs and quality improvement concerns could not only influence the performance of construction projects, but also can affect the way different actors in the sector interact with each other and achieve their divergent objectives.

The aim of this study is twofold. First, it tries to explain the observed disparity increases in construction costs between big (metropolitan) and medium/small regions. Second, it attempts to ascertain the extent of quality problems in infrastructure transport projects after the transfer of quality assurance responsibilities, and suggests measures that could improve the quality of infrastructure transport projects. Surveys and interviews were used as a means to collect data concerning both supplier structure in relation to housing construction costs and quality of construction projects. Other empirical data from a secondary source were also used.

The first part of the research offers an understanding of the behavior of contractors in specific economic situations, specifically by taking into consideration the long-run relationship between contractors and owners/developers. It ascertains that if contractors/subcontractors display opportunistic behavior during the economic boom, the result will be increased higher construction costs. We utilized transaction cost theory in exploring construction sector structures in an attempt to understand changes in the sector from an efficiency perspective. The analysis can also enrich the current understanding of the governance structure of Swedish construction firms and how they could influence construction costs.

As the response from the survey suggests, quality of infrastructure projects has not decreased after the transfer of quality assurance from client to contractor. However, the high number of respondents that indicated quality is the same as before the transfer raises a concern of lack of quality improvement. Respondents have overwhelmingly indicated that the lack of public client competence was one of the contributing factors of quality problems. It is argued that with client competence it is important to build-up through proper knowledge management, incentive systems, and training. Further, the retention of new skilled and experienced workers is an essential element for continuous quality improvement goals and objectives. A second opinion practice from independent experts and committees that focuses on the quality aspect of the projects can be introduced in the provision of infrastructure transport projects. Finally, it is argued that without client competence and a company culture that creates the right incentives, no procurement method can guarantee high quality.
