Denmark’s first cantilevered bridge in 50 years

Innovative collaboration

Several innovations streamlined project delivery and contributed to works being completed three months ahead of schedule. BESIX partnered with Rizzani de Eccher (Italy) and Acciona Infraestructuras (Spain) to form the RBAI joint venture. The project was delivered using a highly collaborative model with all project stakeholders participating in regular LEAN sessions. This model enabled each project stakeholder to be equally involved in understanding project requirements, which optimised productivity, improved decision making and increased time efficiencies by addressing potential challenges before they arose.  

A ‘launching gantry’ was commissioned to install the bridge deck. Specifically designed for this project, this type of horizontal crane allowed the precast deck segments to be fitted one by one. This methodology enabled several production lines to be running concurrently further streamlining the construction process. 

Meticulous environmental planning

Roskilde Fjord is a declared EU Natura 2000 zone and is home to some of Europe’s most valuable and endangered species. Meticulous planning and monitoring ensured BESIX met rigorous environmental and social requirements to protect the fjord’s natural beauty and habitats as well as minimising impacts on the community. This included gaining insight into the migratory patterns of birds that nested on the fjord and planning potentially disruptive works for times when they were away so nesting behaviours would not be impacted. Construction methods were carefully evaluated to ensure selected methodologies would conserve the aquatic environment. Close monitoring during construction ensured that the sediments did not negatively affect aquatic plants such as the protected eelgrass species.
