    description:
    Direktoratet for forvaltning og økonomistyring (DFØ) v/ Statens innkjøpssenter skal gjennomføre en anskaffelse av statlige fellesavtaler om leie av kjøretøy. Anskaffelsens formål er å inngå fellesavtaler som dekker Oppdragsgivernes behov for leie av kjøretøy. Avtalens volum er estimert til mellom 45 – 60 MNOK årlig, og samlet 240 MNOK over fire år. Avtalens totale maksverdi, inkludert opsjoner, er 350 MNOK. Fellesavtalen er delt i to (2) kategorier, én for personbiler og én for varebiler og nyttekjøretøy. For personbiler skal det inngås fellesavtaler på totalt sju (7) delkontrakter. For kategorien varebiler og nyttekjøretøy har avtaleeier til hensikt å inngå én nasjonal avtale. Etter kunngjøring av konkurransen vil avtaleeier avholde et informasjonsmøte om anskaffelsen den 19. april 2023, og interesserte leverandører oppfordres til å delta. For mer informasjon om påmelding til informasjonsmøte og detaljene i anskaffelsen, se vedlagte anskaffelsesdokumenter.

    description:

Anskaffelsens formål er å inngå fellesavtaler som dekker Oppdragsgivernes behov for leie av kjøretøy. Avtalens volum er estimert til mellom 45 – 60 MNOK årlig, og samlet 240 MNOK over fire år. Avtalens totale maksverdi, inkludert opsjoner, er 350 MNOK. Fellesavtalen er delt i to (2) kategorier, én for personbiler og én for varebiler og nyttekjøretøy. For personbiler skal det inngås fellesavtaler på totalt sju (7) delkontrakter. For kategorien varebiler og nyttekjøretøy har avtaleeier til hensikt å inngå én nasjonal avtale. Etter kunngjøring av konkurransen vil avtaleeier avholde et informasjonsmøte om anskaffelsen den 19. april 2023, og interesserte leverandører oppfordres til å delta. For mer informasjon om påmelding til informasjonsmøte og detaljene i anskaffelsen, se vedlagte anskaffelsesdokumenter.

How an AI agent should use this page

Ground rule: Navigate with HTML GET links to keep explanations and relationships. Use the page's JSON alternative only when concrete values must be extracted, compared or computed.

How to use the search_doffin lookup

  1. Replace the placeholders in the HTML GET template; remove optional parameters you do not need.
  2. Check types, units, limits and ID formats in the parameter table.
  3. Follow linked results to canonical pages before combining sources.

Misreading to avoid: An empty list means "no results for this lookup". An error message or unavailable source does not mean the data does not exist.

Source-specific next step

Go to the source page for other operations. Use the JSON template only after the HTML result shows that the parameters and source are correct.
