Imagine constructing a 643—meter-long cantilever concrete bridge, with over 200,000 reinforcing bars and 200 separate pour phases, 55 meters above a Norwegian valley— without traditional 2D drawings. It's an ambitious vision brought to life by the Randselva Bridge.
When the Norwegian public roads administration asked the design-build team to deliver the Randselva Bridge entirely in 3D, the request was met with cautious optimism. Relying solely on a Building Information Modeling (BIM) for a project of this size was unheard of, but the design-build team of Sweco, PNC, Armando Rito Engenharia and Isachsen was up for the challenge.
The design team was led by Tiago Vieira, Managing Director, at Armando Rio Engenharia who then collaborated extensively with the engineering team at Sweco led by structural engineer, Øystein Ulvestad.

EPISODE 1: DEATH TO DRAWINGS (4:00)
Trimble’s structural BIM software, Tekla Structures, coupled with parametric design principles and data sharing, became the central nervous system of the project. The ability to visualize every component to a high level of detail in 3D provided the clarity needed to deliver a bridge with such intricate geometry and heavy reinforcement.
Designers located across Norway, Finland, Denmark and Poland collaborated seamlessly using Tekla Model Sharing, which eliminated information latency and ensured teams were always working from the latest information.
If you put every piece of information that you need into the BIM model, you'll always have up-to-date information available for everyone involved in the project which has massive, massive benefits.
