Oslo municipality's ambition is to limit social dumping and working life criminality through systematised inspections and analyses of suppliers and their manpower in all building and construction sites where Oslo municipality is the builder. A core system shall thus be procured for the receipt, storage, inspection and analysis of manpower data, data on suppliers' and sub suppliers'compliance with financial obligations, as well as possible integration with public registers and internal systems in Oslo municipality. The system shall have flexible functionality and a large potential for further development. The system can later be used for other exposed branches than building and construction.
