Abstract:The change from Design-bid-build to D&C and DBFM-contracts in the Dutch civil engineering industry comes with numerous challenges for the main contractor. One of these challenges is how to outsource to subcontractors. A main contractor can chose between outsourcing only the construction phase or use a more integral approach and outsource design and design verification tasks as well as construction tasks. In this research, a framework is developed based on literature and expert sessions. This framework guides the main contractor in finding the appropriate division of verification tasks between the main contractor and the subcontractor. This framework is confronted with practice in a case study. Based on literature, four factors are determined that influence the appropriate division of verification tasks: the technical complexity of the design, the design verification knowledge and experience of the subcontractor, the size of the outsourcing and the uncertainty of the interfaces of the part that is outsourced has with other parts. The results on the case study match with what was expected based on the literature. The in the literature identified factors seem therefore to be applicable in determining the right division of design verification tasks between the main contractor and the subcontractor in the Dutch civil engineering industry.
