Samenvatting

In the past decade, large infrastructure projects in the Netherlands have often been implemented through Public-Private Partnerships (PPPs), specifically using Design-Build-Finance-Maintain (DBFM) contracts. While the decision to implement projects through PPPs is based on expected advantages for internal parties – the public and private partners in the PPP –, there is a call for more focus on the advantages and disadvantages of PPPs for external stakeholders. External stakeholder management in DBFM projects is based on a contractual division of risks and responsibilities between the partners. However, it is clear from the literature that the contract does not guarantee successful stakeholder management. Relational aspects are important. Little research has been done, however, into the interplay of contractual and relational aspects in achieving successful stakeholder management. This article addresses this research need. A comparative case study was conducted into the PPP projects A9 Gaasperdammerweg and A16 Rotterdam. The study first shows that sanctions, when combined with a relational approach, have a positive effect on the relationships with stakeholders. Second, external stakeholder management cannot be simply outsourced to the private partner and continuous involvement of the public partner is important for success.
