Early contractor involvement in dutch infrastructure development: Initial experiences with parallel procedures for planning and procurement

Traditionally, in the Netherlands, the procurement procedure for infrastructure does not start until the public decision-making procedure is fully completed. In the new procurement strategy, early contractor involvement is applied by carrying out the procurement procedure and the public planning procedure simultaneously. This article explores the first experiences and lessons learned with early contractor involvement in four Dutch infrastructure projects. It can be concluded that the new strategy adds value in terms of time gains, improved project control and more innovative solutions. However, to optimize early contractor involvement, the differences between the competitive procurement procedures and the open, cooperative public planning procedures need to be bridged.
