De Bolder (?The Bollard?) is a 42.5 metre-high building with a circular cross-section of 30 metres and a weight of 25,000 KN. It was built in an industrial plant, transported a considerable distance across water, subsequently put ashore and placed on a foundation. This study focuses on the differences in construction methods and the consequences of these differences. Research aim: How can the De Bolder study results be used to improve traditional construction techniques? Research questions: What are the differences between construction of De Bolder and construction on a traditional site? Where do these differences stem from? To what extent do these differences impact the actual construction period? Results: use of this method depends on the characteristics of the object (volume, design and weight) and circumstantial attributes (transportability). The dynamics of transport determine the building?s design; planning of an off-site construction process entails other dependencies, such as blurring of the distinction between structural works and finishing works.
