Abstract: 
In 2005, a new city development 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, for which a highest possible durability and service life was required, were finished by 2010, most of which include large underwater parking areas in up to four levels. The whole project was carried out by two different contractors with two different strategies and approaches to the durability and service life of the structures.
For all the concrete substructures in the first four parts of the project, which were produced by one of the contractors, a probability based durability design with performance-based durability requirements were applied. For all the other concrete substructures in the last four parts of the project which were produced by the other contractor, the prescriptive durability requirements according to the current European Concrete Standards for a 100-year service life with some additional protective measures were applied. For all the concrete substructures throughout the whole project, the owner and developer also required a performance-based concrete quality control with documentation of achieved construction quality to be carried out, and this gave a unique opportunity to compare the results and experience obtained by use of performance versus prescriptive durability requirements.
