East of the city of Växjö in the South of Sweden, two major highways, Highway 25 and Highway 27 intersect. Today, these two roads converge at a large roundabout that also connects a number of local streets. This road system has been causing issues for a long time, including congestion and poor accessibility. Therefore, the Swedish Transport Administration, in collaboration with the Växjö municipality, decided to construct an interchange allowing both Highway 25 and Highway 27 to bypass and be separated from local streets and pedestrian and bicycle traffic.
WSP is one of the world's leading consulting and engineering companies and its Jönköping office has been working on the reconstruction of Highway 25 in Växjö for many years. Throughout the entire project, the work has been model-based, using Trimble Novapoint software and Trimble Quadri collaboration platform along with other software tools.
"WSP has been involved in this project in various capacities since the road planning stage in 2014," says Axel Erixon, group leader at WSP's office in Jönköping and a seasoned designer and BIM coordinator on Swedish Transport Administration projects. "Right from the beginning, we have been working with a model-based approach. The client, the Swedish Transport Administration (Trafikverket), set BIM requirements from day one. As for tools, we have been using Trimble Novapoint and Quadri consistently, gradually updating the models without losing data, which I consider a strong endorsement of the software."
