Infrastructure projects can act as niches for innovation development, contribute to strategic goals of network owners, and drive broader systemic transitions. However, limited research has examined how sustainability transitions are shaped through narratives and counternarratives around infrastructure projects. Using a case study of the port of Rotterdam, we analyze how three embedded projects - Maasvlakte 2, RDM Campus, and the Hydrogen Pipeline - reflected and shaped evolving narratives and counter-narratives over 20-years. Grounded in the Multi-Level Perspective (MLP), the study demonstrates how an infrastructure owner like the Port of Rotterdam Authority (PoRA) strategically mobilized narrative framing to reshape existing regimes over time. The study contributes to the debate on project management and transition studies by highlighting how infrastructure project owners respond to transition-related tensions by shaping, defending, and adapting project narratives over time, thereby influencing sustainability trajectories.

This editorial scrutinizes the dichotomy of a project’s success and failure, which, in our opinion is too rigid, inflexible, and unnuanced. The aim of this special issue is to nuance this dichotomy by moving toward a process view on how imperfection is brought about in projects. We introduce and discuss five topics important for such a process view: (1) improvisation, (2) temporality, (3) power and politics, (4) transition, and (5) intentionality. We argue that a holistic, processual view of imperfections premises emergence and continuous learning and judgments of the project both in and over time. All five articles in this special issue deal with at least one of the discussed themes of our proposed process view on imperfect projects.

Transferring knowledge across strategic projects is challenging. This study investigates how informal practices of members of the parent organization shape the transfer of knowledge across strategic projects. This was addressed through an in-depth case study of strategic projects in an innovation trajectory of a large public organization aiming to accelerate to transition towards circular construction. We identified five disabling practices: shaming and blaming, disconnecting, holding onto the department and project boundaries, fostering one-way relationships and avoiding internal conflict. Furthermore, we identified three enabling practices: supporting circular projects, sharing similarities across projects and integral visioning. The results contribute to the cross-project knowledge transfer literature by showing how members of partner organizations can enable or disable knowledge transfer across strategic projects. Furthermore, the results contribute to the strategic project literature by illuminating the importance of informal practices of members of the parent organization.

Construction work is associated with high risks of fatalities. Effective, deep and lasting learning from incidents is important for the safety of employees, but not well developed in the construction sector. We studied the organizational processes after a fatality through an auto-ethnographic field work study and found three distinct, but interrelated processes to normalize construction work; juridical, ethical and operational processes. Balanced attention to all three processes supports an effective, deep and lasting learning from incidents. We contribute to the learning from incidents literature with the insight that balanced attention for all three processes helps to learn from incidents and to improve the safety of workers. Furthermore, second victims can be important for the learning of incidents process. Finally, the findings throw new light on inadequate supervision of safety procedures, as the temporary characteristics of projects forces workers to deviate from safety procedures.

For projects to contribute to sustainability transitions, traditional roles of project actors need to be challenged. This paper focus on the changing role of demolishers in circular construction projects. We explore the role changes needed and the tactics adopted to negotiate these changes. Therefore, we collected data across 10 demolishers and two construction projects in the Netherlands. We identified required changes related to task, timing, position, and image. The studied demolishers adopted six different tactics to negotiate these changes. These findings contribute to the sustainability transitions literature by highlighting the important function of projects in operationalizing role changes and enabling change in the roles of incumbent actors. Furthermore, the results contribute to the debate on roles in sustainable projects, and on the roles of demolishers in particular, showing the different elements and non-linear nature of role change, including the unique challenges and tactics adopted by demolishers to negotiate these changes.

This study focuses upon knowledge governance mechanisms of integrating specialised knowledge on underground utilities in large infrastructure projects. The integration of knowledge is essential for the realisation of such projects. The study explores the formal and informal knowledge governance mechanisms in three large infrastructure projects and compares these mechanisms to reveal their effects on knowledge integration. The findings show that combining reward systems, project culture and trust are targeting the motivation of underground experts to share their knowledge and allocation of authority and project network are mechanisms aimed at the coordination between managers and underground experts to integrate knowledge. We contribute to studies on knowledge governance by enabling further empirical insight in the relationships between formal and informal mechanisms.

This chapter presents a holistic investigation into construction culture from an organisation studies as well as project management perspective, mobilising the concept of toxic project cultures as a novel conceptual lens to explore new ways to transform the construction industry into a more dynamic, innovative, and socially responsible sector. All levels of culture will need to change, and to be effective, attention on the part of project leadership to the change process is required on an everyday basis. Inter-organisational strategic change projects can serve as 'temporary trading zones', in which actors from different organisations bring in different work practices, narratives, norms, and values, thus creating opportunities for experimenting, knowledge exchange, and changing behaviour. In these arenas, doing things in unusual ways should always be on the agenda, to unlearn ingrained routines. Unlearning involves very different cognitive processes to learning.

This paper addresses the lack of attention for the behaviours and agency of actors in organizations in the sustainability transitions literature by focussing on practices of inter-organizational collaboration in the transition to circular construction. Practices of inter-organizational collaboration can slow down this transition and are deeply embedded in the construction regime, creating critical points of intersection. This research therefore investigated how reflective interventions can enable project actors to change their practices and support the transformation of critical points of intersection into points of opportunity in circular construction. To answer this question, we adopted a case study approach with action research elements. The results of this study contribute to the sustainability transitions literature by showing how reflective interventions can assist in the transformation of critical points of intersection through five processes, including prioritising reflection on practices, critically evaluating practices, creating a breeding ground for new practices, implementing new practices and embedding new practices in partner organizations. Furthermore, we move away from the focus on policy interventions and offer more room for the agency of actors in projects, by showing how reflective interventions can create experimental environments close to the day-to-day activities of project actors enabling them to simultaneously unlearn obsolete practices and learn new practices.
