Integrale projecten in “cost en baet”. De ontwikkeling van een financieel-economisch rekenmodel en aanbevelingen voor kansvolle samenwerking bij geïntegreerde projecten van infrastructuur & vastgoedontwikkeling.

Delft University of Technology is, and wants to be, a university at the forefront of technological development. As such, it is perpetually involved in furthering technological advancement in the interests of society. In line, the Faculty of Architecture wants to be an international leading (designer’s) education for students and scientists all over the world. As a logic result, the faculty wants to be involved in – and contribute to – the quality of the urban and rural areas in our country. In the densely populated country of the Netherlands, and especially in the western ‘Randstad’-region, there is an ongoing challenge to accommodate numerous kinds of functions. This challenge is coupled with the wish to preserve green areas outside of the urban sprawl. As a result, the demand for (development) sites is provoking increasing interest in inner-city (re)developments. In the Dutch cities, road- and railway-infrastructure occupies a significant area. This fact, in combination with environmental measures, health-related issues and expansion of the infrastructure network, assured that the road- and rail-related areas could count on an increasing level of interest in the last few years. The combination of infrastructure and other functions in one integrated project is sometimes unavoidable and can be beneficial because of several spatial, environmental and financial reasons. The combination of infrastructure- and real estate-development hereby results in high-quality areas in which to live and work. The latest projects (Leidschendam-Voorburg, Maastricht, Delft, Dieren, Amstelveen) also show this vision is more and more supported by public and private actors and can result in appealing projects. Despite the technical and spatial aspects involved, those integrated projects are not not only the field of expertise of the civil engineers or the urban designers. This is, because these kind of developments also need a sound financial and legal base to provide not only in a state-of-the-art technical design and spatial plan, but – even more important – also in a realistic and feasible project. To do so, this present thesis examines combined projects of infrastructure- and urban development with a focus on both the financial and legal aspects. This is done, because we know that by making the right decisions now, the Dutch urban and rural areas will be able to preserve and improve their quality and attractiveness, even when the future may bring something unpredictable\u85Real Estate & HousingArchitectur
