Abstract [en]

The Göta älv-bridge is a welded steel

bridge which is located in Gothenburg,

it connects the inner city of Gothenburg

with the island Hisingen. Cracks was

discovered in the steel in 1999-2000

which started an investigation of the

bridge to clearify the condition of the

bridge. The conclusion was a monitoring

system based on laser light sent through

an optical fiber.

This report describes the bridge, the

damages, the monitoring system and the

traffic on the bridge.

Stefan Pup, at Vectura Borlänge was my

supervisor during this work. In my

investigation the costs of the

monitoring system and the costs of

closing the bridge is compared and

evaluated. The biggest investigating

part is the costs of closing the bridge.

The results of my investigations is that

closing the Göta älv-bridge would cost 1

107 300 SEK / day. The monitoring system

has a cost based on actual costs til

today, and forecasts until 2020 when a

new bridge is expected to be in place,

ending up at 41 144 086 SEK.

To close the bridge would cost a lot of

money. The monitoring system pays back

in about a month with my calculations.

That is a quite short time in comparison

with the 15 years that the bridge has

this monitoring system.
