Trondheim municipality, hereafter called the contracting authority, invites tenderers to a restricted tender contest for the establishment of a dynamic purchasing system (DIO) for the procurement of services for alterant training sessions for pupils at primary and secondary school level in Trondheim municipality. The contracting authority would like qualification requests from actors who can offer training on alternative training arenas for pupils of different thmodations with different needs at primary and secondary school level. It is desirable to get many tenderers into the scheme so that the school has variation in the activities in order to cover the pupils ́needs throughout the entire lifetime of the scheme. In order to participate in the scheme's first competitions, tenderers must be qualified by 18 May 2026. The places will be divided from the competitions that will be held within the dynamic purchasing system. The contracting authority is expected to spend around NOK 2- 4 million per annum on these services. Suppliers can continually qualify for participation in the scheme. Only qualified tenderers will have access to published competitions. A more detailed description can be found in this document with annexes, as well as the Mercell portal.
