Efforts made to save Bergen's warfside "Bryggen"
The engineers are trying to find a way to get the ground water piped back underneath the pier; work that can be detrimental to the World Heritage city’s future.
After an SAS-hotel in Bergen was built in the early 1980s, there have been several ground water leaks underneath the Bergen pier. This has caused damages, and resulted in the foundation of several of the old heritage buildings almost collapsing. A large wall of iron plates was mounted several meters below ground when the SAS-hotel was built. The problem was that the wall wasn’t completely closed, and allowed for water to leak from the ground underneath the protected buildings. Recent measurements show that the ground water underneath the pier is two meters below normal. The reason why is it crucial to keep levels high is because the wood will rot more easily when the water disappears and the level of oxygen increases. The work was started on Friday, but will take time due to the many heritage buildings. The improvements will also be important to help protect archeological materials located underneath the pier from rotting. The damages were first noticed 10-12 years ago, and were first thought to be due to vibrations caused by traffic. Further examinations confirmed that disappearing ground water was the root of the problem. (NRK) Julie Ryland
