Design-Build, innovation, and competition: The role of smaller contractors

Paper i proceeding, 2017

Design-build (DB) contracting can be used to promote innovation in the infrastructure sector. Alongside innovation, public clients often wish to encourage competition.

More risk on the contractors stemming from DB might not appeal to small and medium-sized enterprises (SMEs), as they, ceteris paribus, have a risk disadvantage compared to larger firms. The research question is how more DB contracting will affect competition from a SME perspective. A simple model is provided to show how DBB stimulates competition and DB encourages innovation. Supported by semi-structured SME interviews from Sweden, it is discussed how the hybrid version of a controlled DB contract is inferior to alternative contract designs. The controlled DB contract does not stimulate competition nor provide incentives for innovation
