Phase One of High Speed 2 (HS2) is a high-speed railway currently being built between London and Birmingham. The Colne Valley Viaduct, part of this project, is set to become the longest railway viaduct in the UK.
Â
Challenges
The Colne Valley Viaduct had to meet functional priorities set by HS2, while also being a "Beacon Structure" of international significance. The design of fixed buttress piers proved to be one of the biggest challenges due to their complex geometry and intricate reinforcement detailing.

Achievements
- Through a collaborative approach between the client, contractor, and designer, the project successfully broke through traditional barriers.
- Tekla software played a crucial role in enabling 3D rebar modelling, resolving clashes, improving constructability, and enhancing communication between teams.
- The integrated team's efforts resulted in the viaduct being engineered as a buildable and maintainable structure while adhering to sustainability and safety principles.

Using Tekla software
- Tekla software facilitated collaboration between the designer and contractor, allowing decisions to be made early in the design stage.
- It aided in efficient planning, prefabrication of rebar cages, risk reduction, and improved communication on-site.
- Asset management was also considered, with 3D scanning tools being used for as-built information and Tekla Warehouse for modelling insert elements.
