Project Description

Geometric clarification prior to execution

Banedenmark constructed four new bridges (Lot 1.) for the Electrification of the Railway line Køge Nord-Næstved. The project consisted of four geometrically challenging bridge decks. CN3 solved the geometric challenges with geometric clarification, including setting out data based on the 3D production models. Furthermore, CN3 performed cutting & bending schedules and workshop drawings for reinforcement. CN3 delivered a 100% buildable basis and ensured a productive building process by basing production data for reinforcement and setting out data on the detailed 3D models.

3D models were based on 2D geometry and reinforcement drawings from the tender. Due to the bridge decks’ relatively high geometric complexity, the 3D models raised several questions to the design team. By clarifying these questions in the virtual model instead of on the construction site, Banedanmark could build the bridges based on a well-coordinated and buildable basis. This reduced the number of technical queries in the execution stage and eliminated waiting time in the field. CN3 reduced waste and potential sources of error to a minimum by extracting CNC cut & bend from the model.
The 3D production models have been used to provide a fully digital production basis for reinforcement.

CN3 provided detailed workshop drawings for the reinforcement work on the bridge decks. The drawings are based directly on the constructible 3D model, ensuring complete consistency between the shown and the delivered reinforcement.
Setting out data and the basis for producing rafters is also based on the 3D model, ensuring the overall consistency throughout the entire execution stage.
