Abstract:
A new development comprising a number of business and apartment buildings was completed in 2010 in the harbor region of Oslo, Norway. The development was constructed on concrete substructures positioned in seawater up to 66 ft (20 m) deep. The project was carried out by two different contractors. To achieve the specified service life of 300 years, the first contractor applied the DURACON (Durability Design of Concrete Structures) Model to select the cover thickness, concrete mixture proportions, and reinforcing materials; and the second contractor followed the prescriptive-based durability requirements according to the then-current European concrete standards with some additional requirements and protective measures. The performance of the two contractors are compared.
