Abstract: The implementation of SCC in addition to new reinforcement and form techniques make it possible to increase the degree of industrialisation at construction sites markedly. It has been found that detailed planning and optimization of the building process, following the Lean Construction Principles, are essential utensils to successfully introduce such new techniques.
Main findings of a full scale case study, "the Industrialized Concrete Bridge", are discussed. It was found that significant manpower reductions, improved working environment and higher quality of final result were facilitated by increasing the degree of industrialisation.
The success was, to some extent, dependent on how criteria of SCC were defined and how the concrete properties - and their variation - fulfilled the criteria. Thus, discussion is given on the optimization of robust SCC mixes and test results both from laboratory and building site.
