In order to combat crime, Norwegian authorities have introduced action plans and strategies. This study concentrates on experiences Norwegian contractors have had with a requirement of maximum two contract tiers in their vertical supply chain. Six semistructured interviews with project managers and advisors from contractors in Norway have been conducted, in addition to a literature study. The findings show that the contractors have close to never experienced challenges with the requirement of maximum two contract tiers. The only challenge in this matter is when their sub-sub-contractor needs specialist competence or specialist equipment and are not allowed to use another contract tier. By discussing why the requirement of maximum two contract tiers seemingly works, how it is organized and what perceptions that have been made, this study are among the first to document the conctractors’ experiences from allowing maximum two contract tiers.
