Innovative renovation of Dutch steel bridges
Eight significant steel bridges linking major roads in the Dutch highway system are suffering early fatigue in the orthotropic decks and require renovation. Any repairs involving public highways bring potential congestion for all users of the road network. Innovative solutions which minimise disruption and prolong the lifespan of the bridges are needed to avoid further repairs and consequent disruption, while offering best possible value for public money.
Royal HaskoningDHV, together with Arup and Greisch, form the consortium appointed to deliver the project under a management contract. Royal HaskoningDHV has a record of applying innovative, sustainable solutions to infrastructure development, as well as appreciating the added value of these projects for society as a whole. A pioneering engineering approach is being used in the renovation which involves the application of high strength concrete on steel decks. This will increase the lifetime of each bridge by 30 years at minimal financial cost and decreases negative social impacts through avoiding lengthy traffic delays. The approach prevents extensive steel production and, in reducing the environmental burden, provides a solution which is sustainable as well as economical and practical.
