AUTOMATION AND DATA SYNCHRONIZATION LIGHT THE WAY TO TUNNEL SUCCESS

The Bjonnas tunnel is the second longest tunnel on the newly built motorway E18 from Langangen to Rugtvedt. The project includes several cross passages and technical buildings. In order to complete the tunnelling works as fast as possible, the excavation is ongoing simultaneously in various places. With 4 blasts per day, this is quite a challenge to survey and document.

Tunnels & Tunneling International published the article describing the daily routine, tasks, and challenges of the surveying team.
