De invloed van contractuele en relationele aspecten op stakeholdermanagement

Een casusstudie van de A9 en A16 DBFM-infrastructuurprojecten

Tijdschrift Beleid en Maatschappij, Aflevering 1 2021
Trefwoorden infrastructure projects, public-private partnerships, contractual governance, relational governance, stakeholder management

SamenvattingAuteursinformatie

    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.

Het prestatievoordeel van publiek-private samenwerking

Een analyse van transportinfrastructuurprojecten in Nederland

Tijdschrift Beleid en Maatschappij, Aflevering 3 2020
Trefwoorden Public-Private Partnerships (PPPs), Cost Performance, Time Performance, Netherlands, Principal-Agent Relationships

SamenvattingAuteursinformatie

    Compared to regular contracts, infrastructure development and management through Public-Private Partnerships (PPPs) is expected to lead to better cost and time performance. However, the evidence for this performance advantage of PPPs is lacking. This article analyzes the performance differences of projects with a Design-Build-Finance-Maintain (DBFM) contract (a type of PPP) and a Design-and-Construct (D&C) contract. Project performance data were collected (N = 65) from the Project Database of Rijkswaterstaat and analyzed using non-parametric tests. Rijkswaterstaat is the executive agency of the Ministry of Infrastructure and Water Management. The results show that DBFM-projects have a significantly higher cost performance than D&C-projects. In particular, DBFM-projects have less additional costs related to technical necessities in the implementation phase. Regarding time performance, DBFM-projects seem to perform better although the difference with D&C-projects is not statistically significant. The article discusses explanations for the performance advantage of PPPs, rooted in principal-agent theory. From this discussion, an agenda is presented for further research into the performance advantage of Public-Private Partnerships.

Slimme sturing van publiek-private samenwerking bij publieke infrastructuur

Tijdschrift Bestuurskunde, Aflevering 2 2018
Trefwoorden Public private partnership, DBFM(O)-contracts, Public infrastructure projects, Relational contracting
Auteurs Joop Koppenjan, Erik Hans Klijn, Rianne Warsen e.a.
Samenvatting

    In the Netherlands, the Dutch government public private partnerships (PPP) using DBFMO contracts has become the default option for realizing complex public infrastructures. DBFMO contracts imply the integrated outsourcing of the design (D), building (B), financing (F), the maintenance (M), and also often the exploitation (O) of projects to private actors. The general idea is that by bundling public and private resources, the increasing complexity of today’s public infrastructure projects can be tackled more easily. However, reality is contumacious. As a consequence of several problems related to DBFMO collaborations, the Dutch highway and water management agency Rijkswaterstaat and several private actors recently put forward a new market vision. This vision is a call to reinvent the dominant collaboration practice between public and private actors: relational aspects should be central. In managing projects, more attention should be given to the quality of relations, attitudes, openness and trust. Recent research confirms that the success of DBFMO projects is not only contingent on contractual aspects but also, and maybe even more importantly, on relational aspects. Smart governance involves a shift from the current dominant financial economic-oriented contractual approach to PPP towards a more sociologically inspired relational form of governance.

Publiek-private samenwerking in Nederland en Vlaanderen: een review van veertien proefschriften

Tijdschrift Bestuurskunde, Aflevering 2 2016
Trefwoorden Flanders, Netherlands, public-private partnerships (PPP), review
Auteurs Dr. Marlies Hueskes, Prof. dr. Joop Koppenjan en Prof. dr. Stefan Verweij
Samenvatting

    Public-private partnerships (PPPs) have attracted considerable attention in the Netherlands and Flanders, as witnessed by the recent wave of doctoral theses on this topic. This article presents a review of fourteen Dutch and Flemish doctoral theses, published in the period 2012-2015. The main purpose of the review was to examine what the theses’ most important findings and conclusions are. We found that they mainly focus on themes related to effectiveness, transaction costs, and legitimacy. However, although PPPs are often part of a debate between opponents and proponents, none of the studies found convincing arguments for or against the use of PPPs. Instead, most studies stressed the importance of contextual factors for the success of PPPs. The doctoral theses provided various valuable recommendations for practitioners regarding, e.g., the optimization of PPP procurement and the importance of soft management aspects such as collaborative working and process management. We observed that most theses studied PPPs by applying traditional theories and methods and that the majority focused on the early project phases of planning, procurement, and contracting. More research is needed into the later project phases. Finally, since the generalizability of the theses is limited, more programmatic, quantitative, and (international) comparative research is required.
