Abstract: In 2005, a new city development on Tjuvholmen in the harbor region of Oslo City began. This development project includes a number of concrete substructures in seawater with depths of up to 20 m, on top of which a number of business and apartment buildings have been built. All the concrete substructures were finished by 2010, most of which include large underwater parking areas in up to four levels. For all the concrete substructures, the owner and developer of the project required a service life of 300 years. For all the substructures in the first four parts of the project which were produced by one contractor, a probability-based durability design according to the recommendations and guidelines from the Norwegian Association of Harbor Engineers was carried out. For all the other substructures in the last four parts of the project which were produced by another contractor, the durability specifications were primarily based on current Norwegian concrete codes for a 100-year service life with some additional durability requirements. For all the concrete substructures throughout the whole project, the developer also required a performance-based concrete quality control with documentation of achieved construction quality, the results of which are briefly outlined and discussed in the present paper.
