“…Therefore, design offices usually spend significant time and resources to contact various public and private companies to gather as much existing data as possible at the beginning of the planning phase for large tunnel projects. Norway's National Database for Ground Investigations (NADAG) [9], launched in 2016 by the Norwegian Geological Survey (NGU), is the first nationwide web-enabled open database that archives and distributes all types of ground investigations in Norway. The NADAG database contains many gaps, and raw data are usually unavailable to ensure the quality of geotechnical interpretations [10].…”

In the past decades, Norwegian tunnelling has undertaken a major digital development in all operations from planning to the excavation phase. The breakthrough is driven by digital contract requirements from forward‐leaning clients and innovative industrial stakeholders, aiming for ever more efficient, quality‐oriented and risk‐reducing operations. A formal milestone documenting this development was the publication of Digitalisation in Norwegian Tunnelling in 2019. From 2019, most contracts of new infrastructure tunnels must deliver a level 3 Building Information Modeling (BIM) model. Control systems for drilling jumbos are fully digitalised. All drilling must be monitored and documented with Measurement While Drilling techniques. Via cloud servers, the drilling information is interpreted and delivered live to face engineers for decision support. Sensors are used to monitor rock grouting flow and pressure in each drill hole. Digital electronic detonators with exact delay time are used for blasting. Geotechnical mapping is carried out on field tablets. High‐resolution scans with RGB imaging must be carried out on the exposed rock surface and after rock support/linings. The next step is to utilise all the collected data to a higher degree by advanced analysis with machine learning (ML) and similar techniques for automation and optimisation. This study reviews and exemplifies the digital focus and achievements in core operations in Norwegian tunnel excavation.

“…Such historical geotechnical data are most often useful for getting basic information on the underground geology and its properties, and access to these older surveys and engineering project reports is essential. As an example, the National Database for Basic Underground Surveys (NADAG) Nor and NVE (Solberg et al 2017). Other actors have also joined useful input along the way in development, and Statsbygg was the first to provide a nationwide dataset.…”
