Civil works, airports 

Airport civil works comprise design, tendering, contracting and supervision services in connection with runways, taxiways, aprons and landside access facilities.

The design of airport civil works requires the knowledge of pavement specialists due to the extreme loads that the pavement is exposed to from the heavy aircraft in different climatic conditions ranging from extreme cold weather in the arctic to hot weather in the tropics. At the same time certain parts of the pavement are exposed to fully loaded aircraft at creep speed and other parts only to occasional passes of service vehicles.

Geometrical design

COWI uses programs showing the path of all parts of different types of aircraft enabling us to secure that all requirements of ICAO and FAA will be met, when designing runways, taxiways and apron. In order to accommodate different aircraft mixes flexible aircraft stands has been introduced in order to minimise the length of building facades and thereby reduce cost now and in the future.

Pavement design

COWI applies modern pavement designs using both externally and in-house developed programs in order to cater for different climatic and loading conditions. We use new technologies such as recycling of asphalt and concrete pavements when existing airfield pavement is rehabilitated, giving savings of 20 - 40 % compared to traditional rehabilitation methods.
