We have searched for research-based knowledge of interactions that have been conducted in Norway.

It has been difficult to find reports through open sources.

Under NTNU's leadership, a comprehensive research program called Concept is being conducted. This research programme deals with research related to the development and quality assurance of large investment projects in Norway. As of 2024, this has resulted in three reports addressing interactions in construction or construction contracts. The reports are published in 2016, 2020 and 2023, respectively. We have written a summary from each of these where the two largest amount to more than 100 pages. Reports and other materials at NTNU can be found here.
