The aim is to procure a cloud based (SaaS) system that can as far as possible contribute to the Customer being able to comply with legal and regulation requirements connected to the Norwegian model, including the requirements for an electronic crew list in the builder regulations § 15, the control obligations connected to, among other things, wages and working conditions, as well as following up the Oslo model ́s seriousness requirements. The contracting authority shall revise the seriousness requirements in 2026, which can lead to changes in the municipality ́s follow-up need. The system shall therefore be flexible and scaleable for the municipality. This implies, among other things, that the Customer: * Can apply the solution to contract areas that are particularly vulnerable in relation to working life crime and social dumping, both now and in the future. * May cooperate with other public authorities in following-up work crime and social dumping. * Can see to other needs closely related to this type of follow-up. The system shall be built for high accessibility, safeguarding privacy as well as supporting automated data processing in real time where possible, so that the Customer can safeguard their responsibility in an efficient and secure manner. At the same time, the system should be user friendly with a low response time, simple navigation and work flow, limited risk for error registrations, as well as flexible for comparing and visualising relevant data. See SSA-L, annex 1 for further information on the Contracting Authority as well as its purpose and extent.
