The construction sector is essential for societal functioning yet faces significant challenges, including shortages in physical and human resources, extensive material and energy use, and low productivity growth. The Dutch construction industry, in particular, is grappling with a housing deficit, rising construction costs, and restrictive nitrogen policies. Additionally, a complex situation with infrastructure rehabilitation, known as the V&R challenge, demands immediate attention. This research focuses on the rehabilitation of bridge infrastructure assets, many of which were built in the 1950s and 1960s and now require renovation or replacement. The surge in demand for these activities is expected to surpass the current supply capacity, necessitating a transition in infrastructure project execution towards industrialisation.

The study analysed the concept of industrialisation in the Dutch bridge infrastructure context, aiming to understand how innovations and sector characteristics influence the potential for an integrated industrialised value chain. Using a qualitative methodology, the research employed the Technological Innovation Systems (TIS) approach, supported by semi-structured interviews. The findings indicated that while numerous innovations could contribute to industrialisation, no singular combination ensures an industrialised value chain due to contextual factors. A proposed framework, the Industrialised Infrastructure Construction (IIC), outlined conditions necessary for a functioning industrialised system, including continuity of demand, standardisation, and long-term relations, amongst others.

The TIS analysis identified several systemic barriers: lack of upfront coordination and long-term planning, insufficient support for innovation and knowledge exchange, a conservative culture in a competitive sector, and insufficient interdisciplinary collaboration. Addressing these barriers through policy instruments and organisational strategies is crucial for fostering transition efforts. Further research is recommended to validate the IIC framework and explore the cultural impacts on sustainable innovation. Practical recommendations emphasise the importance of interdisciplinary collaboration and long-term commitment to standardisation for all actors involved in bridge rehabilitation.

Public clients in the Netherlands have committed to dramatically reduce CO2 emissions. To achieve that, Circular Economy is proposed and more specifically a tool that can lead to Circularity, called Product Service Systems (PSS). PSS is a business tool that is innovative for infrastructure, and public clients are investigating the transition towards service-oriented projects. Literature suggests that when public actors undergo transitions, their public values are also affected. It is yet not thoroughly studied how the public values are coupled with PSS. Aim of this research is to investigate how public values are affected when public actors that own infrastructure assets implement PSS. Firstly, a literature review concerning public values is conducting. Then, the PSS characteristics, barriers and benefits are theoretically studied. A framework that couples public values with PSS is designed. To analyze and enrich this framework, a real-life implementation is studied. The Province of North Holland (PNH) served as case study, and more specifically the guardrails pilot that PNH realized within the Circular Road Program. Interviews were conducted to collect the data. To analyse the interviews, thematic analysis was utilized. Two rounds of analysis were conducted, a deductive and a reflective round. The findings of the thematic analysis were validated and generalized by an expert panel consisting of three experts. As a result, the empirical findings of the results were found. An overview is designed and the theoretical and empirical results are presented and compared. The values that are mostly affected when PSS is implemented are Lawfulness, Accountability, Collaboration and Innovation. The overview is a useful input for public clients, because they can gain knowledge about how they can include the values perspective in their decision-making process.
