Bergen International Airport is located on the west coast of Norway, where it provides services to the inhabitants of Norway's second largest city.
The runway in Bergen International Airport is designed according to the NATO standard where each end consists of PCC (Portland Cement Concrete) and the central part consists of asphalt. Over time distresses on the east end of the runway have developed and they had at the time of the project reached a state where works needed to be carried out.
Thus, Ramboll was approached to carry out a feasibility study for assessing the development of the distresses and determining the optimum repair alternative that would provide most value for money for the operator. The works comprised identification of the cause of distresses and determination of three different repair alternatives that could be implemented considering the operational constraints for an international airport with only one runway. The assessment of the most cost-beneficial repair alternative was based on a 20 year life cycle analysis where the net present values of the different options were determined and compared.
