Project Delivery Methods in Large Public Road Projects – A Case Study of E6 Jaktøyen - Sentervegen.

In recent years, the size of road projects has increased significantly. These projects face several challenges due to the size and the complexity of the projects. The purpose of this paper is to identify the project delivery method of a large road project in Norway and to explore the nature of the challenges the project faces. In addition, the paper will assess how implementing early contractor involvement (ECI) affects these challenges in the case project. In addition to a literature study, a case study on a public road project was carried out. The case study was conducted by a document study and semi-structure in-depth interviews with ten key personnel. The key personnel include representatives from the client side as well as representatives from the design team and the main contractor. Even though the project is large and complex, the client has used design-bid-build (DBB) as project delivery method. By using this project delivery method, the client faced several challenges during the early stages of the project execution. Some of the client's challenges were shortcomings in the design, as well as lack of control of the subcontractors. By involving the contractor's knowledge in the early phase, some of the challenges could have been reduced. Since the project will not be fully implemented until the spring of 2019, the paper addresses challenges in the early execution phase of the project. ECI should be considered in such large and complex road projects to reduce challenges that could appear in the execution phase. Since several large and complex road projects are coming, the experience from this case study could help them to decide the project delivery method. [ABSTRACT FROM AUTHOR]
