Förebyggande Brounderhåll

Sammanfattning: Abstract The Swedish Road Administration in the region of Mälardalen has since 2004 worked to in¬crease the efficiency of the maintance of bridges based on limited functional requirements and time demanded action. The maintenance of the bridges is contracted in the county of Uppsala since 2004, and Örebro since 2007. The county of Nyköping and Västerås is contracted by the traditional system. The contractor will perform a regular maintenance on all bridges. The bridges are inspected by the contractor at least once every year. The contractor registers the result of the inspection in a database called BaTMan. BaTMan is a Bridge and Tunnel Management system and is a strictly web solution were the user logs in via the internet. The Swedish Road Administration also inspects the bridges to se that the demands on the bridges are followed. My work is to compare these different inspections and to see any development.
