      NAKSIN (Nye aktsomhetskart for snøskred i Norge) er et verktøy under utvikling/uttesting for å identifisere potensielt skredfarlige områder med hensyn på snøskred. Verktøyet har som mål å skulle erstatte det eksisterende ...

    • I hvilken grad kan digitalisering føre til økt produktivitet? 

      Antonsen, Mia (Master thesis, 2019)
      Produktivitet er et omdiskutert tema i byggeindustrien, hvor det ofte blir poengtert at denne bransjen har lavest produktivitetsvekst sammenlignet med andre næringene. Dette kommer mye av at bygg- og anleggsbransjen er en ...
