Reconstruction of the Bergerstraße Bridge

BIM Management Phases 1 – 8 for the Bridge Project on Bergerstraße

The Bergerstraße Bridge in Cologne, a key link between the districts of Porz and Eil, is an 11-span structure that crosses six tracks of the DB AG railway. As a central east-west connection, it has played a critical role in the city’s traffic flow since its construction in 1965. Due to its poor condition, the City of Cologne has decided to demolish the structure and plan a replacement.

One of the key challenges of this project is the proximity of residential buildings and the extremely tight space available on site. Particularly on the western side, the ramp of the bridge directly borders the tracks of KVB AG, adding further complexity to the planning and execution of the replacement. The high volume of traffic, with trains passing by every minute, requires precise coordination of the construction processes to minimize disruption to residents and public local, long-distance, and freight transportation.

SD Engineering is supporting the client and planners as an external BIM manager in developing and implementing the BIM methodology for the project. Given the increased demands on the existing model, the BIM methodology is intended to facilitate conflict-free planning and execution of the demolition and reconstruction, especially regarding the processes and construction logistics under the challenging spatial constraints on site.
