Circular construction offers sustainable solutions and opportunities to disentangle a project’s life cycle, including demolition, deconstruction and repurposing of architectural, civil engineering and infrastructure projects from the extraction of natural resources and their wasteful usage. However, it introduces additional layers of novel risks and uncertainties in the delivery of projects. The purpose of this study is to review the relevant literature to discover, classify and theorize the critical risk factors for circular construction projects.

The paper conducted a systematic literature review to investigate the risks of circular construction projects. It deployed a multistage approach, including literature search and assessment, metadata extraction, citation frequency analysis, Pareto analysis and total interpretive structural modeling.

Sixty-eight critical risk factors were identified and categorized into nine broad taxonomies: material risks, organizational risks, supply chain risks, technological risks, financial risks, design risks, health and safety risks, regulatory risks and stakeholder risks. Using the Pareto analysis, a conceptual map of 47 key critical risk factors was generated for circular construction projects. A hierarchical model was further developed to hypothesize the multiple possible connections and interdependencies of the taxonomies, leading to chain reactions and push effects of the key risks impacting circular construction projects.

This study constitutes the first systematic review of the literature, consolidating and theorizing the chain reactions of the critical risk factors for circular construction projects. Thus, it provides a better understanding of risks in circular construction projects.

The aim of this study is to report and reflect on the development of a tailored executive education programme rooted in state-of-the-art research and focused on enhancing and embedding project leadership competences in a multi-national project-based organisation.

Through a detailed description of an example of a leadership development programme, the paper reflects on the learning journey. Drawing on research in management education, leadership and project management competence development, the authors present the rationale, design, delivery and participant and organisational experiences.

Reflections on the learning journey identify five key points: a) the fundamental role of a programme champion, b) the importance of balancing rigour and relevance in executive education programme design, c) the importance of attending to the milieu of the clientele in terms of culture, demands and where they are in terms of their learning journey, d) the significant role that reflection can play in personal development and e) the competences necessary for project leadership.

This paper reflects on a single programme for a single organisation and is therefore at risk of being idiosyncratic and not generalisable. This is indeed a limitation. However, the authors are all experienced in delivering executive education – and therefore can use those experiences to view the reflections. Many of the considerations noted here resonate with other programmes (both in support and through experience of omission having detrimental effects).

The paper provides new insights into developing enduring and effective leadership competences in complex project management, i.e. one that has a lasting impact on the organisation and is recognised to provide benefits. The reflections on how the authors charted a course and embarked on a journey are deemed of relevance to academics and industry.

The paper provides, for both industry practitioners and academics, new insights into effective leadership development in complex project management, one that has a lasting impact on the individual and the organisation and is recognised to provide benefits.
