Unpublished © Council on Tall Buildings and Urban Habitat / Frits Scheublin Tall Buildings in the Netherlands, Constraints to Innovation, a tool to preserve green fields. Prof. Ir Frits J.M. Scheublin Royal BAM Groep nv, Bunnik, The Netherlands, Tel: +31 30 659 8677 Eindhoven University of Technology, The Netherlands, Tel: +31 40 247 8391, Email: [email protected] Abstract The Netherlands is a densely populated country with 16 million inhabitants. About 50% of the population lives and works in an area about as large as London or Paris, cities of about 8 million people. The green fields in this country are, step by step, being lost to city planners in need of more land. Environmentalists are not able to stop this land-swallowing trend, which is becoming a monster. High-rises seem to be a suitable solution to limit the urban growth and preserve the green fields that are left. Currently, high-rise buildings dominate only a minor part of the skyline in The Netherlands. Therefore, a research project was defined to inquire into the constraints of High-Rise construction. The project, in particular, focussed on the question of whether innovative construction processes could possibly lower the construction costs of Tall Buildings. Consequently, could the use of high-rises, as a solution for housing needs, also be a preservation tool for the remaining green fields.

CTBUH 8th World Congress 2008 1 Tall Buildings in the Netherlands, Constraints to Innovation, a tool to preserve green fields. Prof. Ir Frits J.M.

Consequently, could the use of high-rises, as a solution for housing needs, also be a preservation tool for the remaining green fields. The questions to be answered in this research were: x Will lowering the cost of high-rise construction effectively encourage project developers to propose more high-rises? x Why does high-rise construction not provide more benefits from the economy of scale and why is little significant innovative progress demonstrated? x How could we improve the conditions for innovation in high-rise projects? x What type of innovation is most needed in high-rise construction?
