LOD 350 is becoming the new baseline for coordination-heavy projects.
LOD 300 can show design intent, but today’s commercial, healthcare, and mission-critical buildings need more than that. They need structural models that support real coordination before construction reaches the field. Openings, sleeves, embeds, connections, penetrations, and trade interfaces need to be visible early, not discovered during installation.
That is why structural BIM is moving from basic modeling to coordination-ready detailing.
In 2026, the question is not whether your model looks complete. It is whether it is detailed enough to prevent costly field conflicts.
At TopBIM Company, we model for coordination, constructability, and clarity from the start.
What are you specifying today: LOD 350 as the baseline, or LOD 400 in critical zones? Let us know in the comments.
