From a technical and economical point of view the design-build project can be regarded as successful. The cost was normal and the technical outcome good, or even in some respect very good. This VTI report concludes and analyses a design-build procurement on road N610, north of the city of Halmstad in Sweden, after a seven year contract period with performance requirements. This object has been followed up by others from the stage of preparing the procurement documents to the stage of opening the road for traffic. The object has also been part of the efforts of the Royal Swedish Academy of Engineering Sciences (IVA) to facilitate development of procurement forms. This report focuses on the more technical aspects of the project, in particular the relationship between procurement design and the outcome in terms of measured technical parameters and the economical result of the bonus-malus system.
This project is one of few that have been followed up to document and share ideas and results in the current development of procurement forms so desperately needed. In Sweden, the project should also be used in the context of the substantial share of contracts today offered as design-build or even with extended responsibilities for maintenance or operations (performance contracts). Ten years ago, however, the experience was limited of these contracts and it is evident that this project has been a learning process for both contractor and client.
Moreover, it can be concluded that there are requirements and measurement methods that are unreliable but this cannot be proven to have influenced the result in a negative way.
