Level of detail (LOD)
What is LOD?
In the world of BIM (Building Information Modeling), LOD can stand for "Level of Detail" or "Level of Development". It's a term used to describe the accuracy of a model.
First and foremost, the LOD highlights the model's reliability to all project stakeholders, thereby increasing their confidence in it. The more reliable the information in the model, the more likely it is to be taken up by project stakeholders. Information passes quickly from one person to another, and decision-making becomes faster.
The Level of Development (LOD) specification is a reference enabling structural engineering offices to specify and clearly state the content and reliability of building information models (BIM).
With a LOD 350 the model element is represented graphically in the model as a specific system, object or assembly in terms of quantity, dimension, shape, orientation, and interfaces with other building systems. Non-graphical information can also be attached to the model element.
LOD + BIM execution plan = savings
When we look at the cost breakdown of major construction projects, we see that, thanks to 3D software, the manufacturing phase is extremely efficient. Design and manufacturing together account for only around 15% of an average construction budget.
