The contracting authority estimates that the total purchase over four years will be approx. NOK 8 - 9 million excluding VAT (including options). This estimate includes all four lots. The scope of this framework agreement will vary from year to year, depending on many different factors. The contracting authority has therefore set an upper limit to this contract in order to ensure continuity in deliveries and an increased predictability for the contracting authority and the chosen tenderer. The upper limit is set at NOK 12 million excluding VAT, including options, in total for all four lots and over four years.
