Accoya® Bridge Set To Span the Flow of Time
Published: 25/09/2014 by Accoya®
Accoya®, the world-leading modified wood manufactured by Accsys Technologies, has been used to create a unique “floating” bridge in the Dutch city of Bergen op Zoom.
Completed earlier this year, the bridge spans Pielekenswater and its design was inspired by the work of Dutch military engineer Menno van Coehoorn, who built the 18th century Revelijn op den Zoom fortress in the same location.
Ro Koster and Ad Kil, of Bergen op Zoom-based RO&AD Architects, who also mastered the famous and award winning Moses Bridge in Halsteren, designed the 80m floating pedestrian bridge to allow access to the 18 century fort’s entrance. Its snake-like path mimics the journey and motion of the boats which originally travelled there.
The deck of the bridge, which is made entirely from Accoya, sits close to the water at Pielekenswater. Thanks to Accys Technologies’ proprietary acetylation process the wood is well equipped to deal with such a high-moisture environment. With class one durability guaranteed for 25 years and dimensional stability that sees swelling and shrinkage reduced by 75% and more compared to other wood products.
Exceeding the high-quality and aesthetic attributes of tropical hardwoods, Accoya also boasts excellent environmental credentials; it is sourced from FSC® certified forests and certified at Gold level by the Cradle-to-Cradle Products Innovation Institute.
The bridge was built by Alldlex Watersports, from neighbouring Halsteren.
Ro Koster, of RO&AD Architects, said: “In building the floating bridge, we were inspired to take people back in time to when regular journeys were made from the city to Van Coehoorn’s fort to supply troops with equipment.
“Accoya was the automatic choice for this project. Its strength and durability combined with its construction flexibility made it the ideal wood to work with. Accoya’s environmental credentials are also appealing - we wanted to work with a timber which would not only deliver excellent strength and durability but was also sustainably sourced. Given Accoya’s modification process is C2C certified, the product fitted seamlessly with our principles of sustainability.”
Bryan Crennell, director of sales and marketing at Accsys Technologies said, “The Moses Bridge has become quite an iconic structure and Ro Koster and Ad Kil’s new floating bridge is just as impressive. Following the success of the Moses Bridge we are delighted RO & AD Architects have selected to use Accoya for this project. The stability and durability of Accoya will ensure that the cultural and architectural history at Bergen op Zoom can be enjoyed for generations to come.”
Accoya has, to date, been used in a number of marine applications including a boat house and horning on the Norfolk Broads and canal lining in the Netherlands. Its ability to withstand the risks posed by exposure to water coupled with its outstanding aesthetic qualities and sustainability credentials make it the ideal material for the market.
