    Anskaffelse av rammeavtale for service og vedlikehold av porter
    description:
    Anskaffelsen omfatter service og vedlikehold av porter. Oppdragsgiver har garasje-, gang- og kjøreporter og andre porter særlig på sykehjem, brannstasjoner, større og nyere barnehager, skoler samt andre bygninger. For at disse tekniske installasjonene skal oppnå forventet funksjonstid og for å unngå driftsstans, bør det gjennomføres jevnlig ettersyn på installasjonene. Formålet med anskaffelsen er å få etablert en rammeavtale for periodisk oppfølgning av alle slike installasjoner, samt uttrykning og håndtering av akutte feil. Velfungerende anlegg vil bedre kundetilfredsheten og redusere kostnader knyttet til reparasjon og utskiftinger. Nærmere beskrivelse av formålet med anskaffelsen og innholdet i leveransen fremgår av Vedlegg 2 Ytelsesbeskrivelse.

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.
