prof.dr.ir. L. Volker (Leentje)

My name is Leentje Volker and I am a Professor of Integrated Project Delivery (IPD) at the Department of Civil Engineering and Management (CEM) of the Faculty of Engineering Technology (ET) at the University of Twente (UT), The Netherlands. Next to this I am a member of the Dutch Council for the Living Environment & Infrastructure (Rli). In this role we advice the Dutch central government on issues related to how we governance our built environment. 

Intrigued by interaction between people and the public built environment, the aim of my IPD group is to create feasible and integrated civil engineering solutions that add value to society and stimulate innovation in the construction industry. For me, public infrastructure projects are collaborations between public and private partners that facilitate strategic infrastructure asset management decisions. 

As an construction management scholar, I mainly focus on the initialisation, design, realisation and maintenance of civil infrastructure assets in networks and (eco)systems. This includes procurement and contracting of (a portfolio of) physical infrastructures, the design of collaborative project organisations and the inter-organisational aspect of project practices. 

Integrating individual, organisational and institutional levels of socio-technical engineering solutions in a project based environment like construction contributes to a wide range of social, technical and economic values. Moving towards a more ecosystemic way of working in the built environments requires that these values are balanced between a complementary set of actors that both create and capture values. 

My co-creative and multidisciplinary empirical research approach often leads to interesting and innovative results that bridge the gap between theory and practice. This fits with my active social engagement in (advisory) committees and boards and strengthens my role of change agent in the construction industry.

Feel free to walk into the Horst Z219 or send me an email if you would like to join me on this co-creative process of developing knowledge, competences and innovations together.

Most of my research focuses on the creation of values for the complete construction ecosystem by explicating the tensions and dilemmas between fragmentation and integration, formal and informal rules, legal and social systems. I find it particularly important to exploit the exploration phase and explore the exploitation phase in collaborative construction processes.

Most of my research is related to: procurement and contracting of civil infrastructure, project organising and construction management, strategic asset management processes, collaboration between public and private partners in the construction industry, developing innovation and governing business ecosystems, and business model design.

I have a co-creative, design oriented and qualitative multidisciplinary research approach which leads to interesting and innovative results that bridge the gap between theory and practice. Most of my research data is collected through interviews, (participant) observation, workshops, serious gaming, or surveys, often in engaged scholarship with practitioners.
