About Me

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. Intrigued by interaction between people and the public built environment, the aim of me and my group is to create feasible and integrated civil engineering solutions that add value to society and stimulate innovation in the construction industry. 

As an construction management scholar, I focus on the realisation and maintenance of infrastructure assets in networks and (eco)systems. This includes procurement and contracting of (a portfolio of) social and economical infrastructure, the design of project governance and the reality of project organising.

I consider construction projects in the public sector as collaborations between public and private partners that involve strategic asset management decisions for public infrastructure. Connecting individual, organisational and institutional levels contributes to balanced way of value creation and value capture of a wide range of values.

My co-creative and qualitative multidisciplinary research approach often leads to interesting and innovative results that bridge the gap between theory and practice. This fits with my active social involvement in committees, boards and public meetings. Feel free to walk into the Horst Z226 or send me an email if you would like to get to a higher level of knowledge together.

I believe that value can be created for the complete construction ecosystem by explicating the tensions and dilemmas between fragmentation and integration, formal and informal rules, legal and social systems. Therefore I find it particularly important to exploit the exploration and explore the exploitation in 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 models design.

I have a co-creative 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.
