The New Norm of Circular Construction: Accelerating successful employment of vertical integration of modular construction’s project- and product value chains. An empirical single case study of an integrated modular building company

In recent years, the housing market has been under pressure due to growing demand for (inner-city) housing and a lack of supply. Housing is in high demand as a result of factors such as population growth, rapid urbanization, smaller households, the freezing of "mobility in houses, and so on. The low developing speed to cater to these issues...

Prototyping a domain-task ontology for facilitating strategic decisions of asset managers of public sewerage systems

The current research stems from the motivation of reducing the information loss that asset managers face in the operation & maintenance phase of the project. Most of the public infrastructure assets’ condition nowadays deteriorate due to ageing and municipalities confront challenges to manage their portfolios effectively by adopting...

Explorative case study to gain insight on the consequences of circular infrastructural construction projects: Investigating the effects of circularity in construction projects on project process and construction costs.

The aim of this research was to investigate the effects of implementing circularity in infrastructural construction projects. As a very polluting sector, circularity is becoming a more and more popular theme in the construction industry. Driven by both governmental regulations of reaching a full circular economy in 2050 and intrinsic motivation,...

Triggering Social Entrepreneurship Initiatives: Investigating the role of Dutch national government policy in triggering social entrepreneurship initiatives focusing on delivering affordable owner-occupied housing

The Netherlands is currently facing a shortage of affordable housing, specifically for middle-income households. These households with too much income to qualify for social housing but not enough to buy a home tend to squeeze into the free rental market increasingly. Housing specifically targeted at this group is known as intermediate housing,...

Circularity in infrastructure projects with Early Contractor Involvement: Investigating the knowledge contribution of contractors towards circular construction in the design process

The number of raw materials consumed and waste generated by the construction industry is no longer a viable solution in the future. It is required for the construction industry to move from a linear towards a circular economy (CE) by circular construction (CC). The unfamiliarity in actions that need to be taken for CC is still new terrain for...

Blockchain for Circularity: Hyperledger Fabric-based Material Passport Framework

The Linear Economy currently follows the Take - Make – Dispose model. This paradigm is based on the consumption of resources rather than the preservation of their value. If this model remains dominant, it will lead to material scarcity, thereby increasing materials prices. The linear economy has a negative effect on nature as this model creates...

Implementation fidelity of circularity in publicly tendered civil engineering projects

With the current urgency to become more circular, procurement presents the primary method to deliver the circular policy ambition by purchasing circular products and stimulating circularity in the market. In the building and infrastructure sector, civil engineering projects offer unique opportunities for circularity. This research presents an...

Radical Vernacular: A New Ethiopian Urbanity

Addis Ababa is a city experiencing a huge population boom, and where the vast majority of housing can be classified as “slum”. State-owned kebele housing, which houses an estimated 40% of the city’s inhabitants, has very low rents but is not maintained, leading to deterioration. Thus, the city is left with a severe shortage of adequate housing....

Talking circularity - the influence of actors on the building process: A study into actor networks and influence on decision-making regarding the implementation of circularity into the building process.

The purpose of this master thesis is to gather information from current practices and make recommendations to facilitate implementation of circularity in the building process. The past years, circularity has become a popular term in the built environment. This approach prefers a more circular way of perceiving the building process. Literature...
