Nordic Study of Classification Systems for Infrastructure & Transportation Author: Phil Jackson Version 1.0 July 2020 bSI Document Number: IR-2020-1022-TR Practical Requirements for Classification of Information in Digital Engineering & BIM Report Key Contributors: Knowledge without understanding is meaningless. – Douglas Adams – ‘The Hitchhikers Guide to the Galaxy’ We are stuck with technology when all we really want is just stuff that works. How do you recognize something that is still technology? A good clue is if it comes with a manual. – Douglas Adams – ‘The Salmon of Doubt: Hitchhiking the Galaxy One Last Time’ 2 Table of Contents 1 Executive Summary
