Level of information need
Ever feel like you’re drowning in BIM data you don’t need, or scrambling for details that should’ve been there? Enter the concept of Level of Information Need. It’s a straightforward idea buried behind a not-so-straightforward name (looking at you, BS EN ISO 7817-1:2024). In plain English, a Level of Information Need defines exactly what information should be delivered – no more, no less – for a given BIM use case or project stage.
