Bifrost Bimodular formable robust timber bridge

Purpose and goal:

The purpose of the project was to further develop the concept, Bifrost, from a technical and architectural perspective, i.e. to develop the technical solutions, and to develop the bridge design with regard to durability and aesthetics. Furthermore, we have also worked with the safety of the bridge, based on a human experience but also visually and aesthetically.

To shed light on these questions, a workshop was held, which in itself was an objective within the project. The project has created a more refined product that can provide a climate-smart alternative to a concrete or steel bridge. Expected results and effects:

An insight has been that bridge design is a very complex and interwoven design process, where a great common understanding of the various aspects that affect a bridge is necessary to reach good results. The project´s results are a step in the right direction towards the goals of Agenda 2030. This is because the bridge is mainly built from renewable and reusable materials.

The proposed innovations that have been developed within the project promote an ecologically and economically sustainable transport infrastructure that contributes to climate-neutral transportation. Approach and implementation:

The project has been carried out within the triple helix model of innovation, i.e. a close collaboration between academia (KTH), business (TBS, Gaia, Funkia) and the public sector (City of Stockholm). 3 parallel work packages (WP): WP1 Design, aesthetics and durability; WP2 Construction and load-bearing capacity; WP3 Administration, Communication and Marketing has been completed. WP2 and WP3 have delivered expected results within time and budget with support from WP3.

The close collaboration between the group members has been necessary and rewarding to achieve the good results.
