Storm surge barriers, a critical component of the Dutch Delta Works, faces growing operational challenges due to climate-induced sea-level rise and increased storm intensity. These developments are expected to lead to significantly more frequent closures, creating not only ecolog ...

Improving sustainability in property asset management companies

Exploring the role of the Corporate Sustainability Reporting Directive (CSRD)

In recent years, sustainability has become an increasingly important topic for property asset management companies. However, implementing it within daily operations remains a significant challenge. While regulatory initiatives like the Corporate Sustainability Reporting Directive ...
This thesis addresses the persistent challenge of cost estimation inaccuracies in the Dutch road construction industry, with particular emphasis on learning from previous projects to improve forecasting practices. Despite substantial progress in estimation techniques, cost overru ...

Human-Centric Project Performance in Construction Projects

Integrating Behavioral Team Dynamics into Project Management Frameworks

This thesis investigates the integration of human-centric factors (HCFs) of communication, trust, and flexibility into project management frameworks to enhance performance in civil and offshore constructions. As a reaction against the usual 20-45% cost overrun and 30% schedule de ...

Timber in Transition

Examining Socio-Technical and Enabling Processes in Residential Construction from a TIS framework perspective

The construction industry is under growing pressure to reduce carbon emissions in response to climate change and regulatory demands, particularly in the Netherlands, which has set a goal of cutting greenhouse gas emissions by 55% by 2030. Timber construction emerges as a promisin ...
Megaprojects are inherently uncertain due to their scale, complexity, and unique, one-time nature, making accurate forecasting challenging. Throughout the project lifecycle (PLC), multiple internal and external stakeholders often perceive uncertainty differently due to their vary ...
The Dutch Climate Act (2019) requires a substantial reduction in greenhouse gas (GHG) emissions, targeting a 49% reduction by 2030 and 95% by 2050. The construction sector, which is responsible for 15% of the Netherlands' CO2 emissions, largely relies on concrete, a material that ...

Managing Transitions Toward Adaptive Delta Infrastructure

A framework for improving the decision context stage

Because of the potential consequences of sea level rise, decision-making to set adaptive strategies to handle the uncertainty over these consequences is required. There are several decision-making methods to deal with deep uncertainty and attempt to contain the impacts of sea lev ...
Mumbai,as a rapidly growing megacity faces considerable challenges with its CDWM endeavours. This research is motivated by the unique context of the city, characterised by its highly fragmented construction industry in critical need of government interventions, to promote effect ...
This research is about the contribution of community engagement professionals (CEPs) to project result. CEPs focus mainly on stakeholder management but also have other responsibilities like permits, claim handling and cables and pipes detection. There are several studies on stake ...

Sustainability, a requirement in projects

An exploratory research to develop a framework for sustainability requirements management in Transmission System Operators (TSO) projects

Sustainability has become a prominent term in policy-oriented research as an expression of what public policies seek to achieve (Kuhlman & Farrington,2010). It has been a developing idea, frequently receiving attention from society, governmental agendas, and the innovative fi ...

Flood Risk Assessment Isiolo River Basin, Kenya

Feasibility of the SLAMDAM in the Isiolo River Basin using the FIS Tool

This report provides a flood risk assessment of the Isiolo River Basin, in collaboration with Nelen & Schuurmans (3Di, FIS Tool) and Zephyr Consulting (SLAMDAM). This flood risk assessment includes a study of the current flood risk management in Kenya, and in the Isiolo River ...
Recently, the construction industry has been confronted with changing regulations, especially with the advent of sustainability goals and circular economy ambitions. The Dutch government wants to accomplish its ambitious initial objective of using 50% fewer primary resources by 2 ...
The Architecture, Engineering, Construction and Operations (AECO) industry can be descripted as a fragmented industry, with relatively low productivity and efficiency. Digital solutions like Building Information Modeling (BIM) can increase an organization's productivity. However, ...
