What is Level of Accuracy?
The Level of Accuracy (LOA) is a measured or represented accuracy. For BIM, it is a measure of how well a model matches the actual building. The LOA is expressed as a number scale from LOA 10 to LOA 50. An LOA 10 means that the BIM model is within 100mm or 5″ whereas an LOA 50 means that the BIM model is within 1mm or 1/16th of an inch. The higher the LOA, the more accurate the BIM model.
What does LOD stand for?
LOD stands for Level Of Detail/Development/Definition – yes, Level of Development, Level of Detail, and Level of Definition! Three answers! 😖
What is Level of Detail/Development/Definition?
Commonly, LOD is a numbered scale used to describe the amount of detail in a BIM model. In the USA, the scale goes from LOD 100 to LOD 500.
There is a lot of controversy around the use of LOD as its definitions can vary in each country. Generally, the higher the number, the more detailed the model.
For example, an LOD 200 element might just show the overall shape of a door, while an LOD 400 element would show all the small details, such as door handles, panels, hinges, and details required to fabricate the door.
What does LOG stand for?
LOG stands for Level of Geometry.
What is Level of Geometry?
Level of Geometry (LOG) is also a scale that focuses on the amount of geometric detail in a BIM model. There are many versions of LOG, so be careful to specify/clarify exactly what the requirements are!
What does LOI stand for?
LOI stands for Level of Information.
What is Level of Information?
The Level of Information (LOI) scale measures how much non-geometric data is in a BIM model. This data can include material properties, thermal properties, weight, etc. Using a single LOI number to specify a long list of requirements can be confusing because some requirements might not actually be needed. It is usually better to define the actual requirements more clearly using the Level of Information Need framework.
What does LOIN stand for?
The standard forbids abbreviating this term, but many people still do it.
So to help you out when you hear LOIN in reference to BIM (and not your Sunday dinner 🥩), LOIN refers to the Level of Information Need.
What is Level of Information Need?
Level of Information Need (LOIN) is a framework to help define the amount and types of data required for a particular purpose. The requirements are defined by 1) Geometry, 2) Information, and 3) Documentation. The Plannerly scope module provides the exact framework required to follow the Level of Information Need principles.
What does MPS stand for?
MPS stands for Model Progression Specification.
What is Model Progression Specification?
A Model Progression Specification (MPS) defines how a BIM model should be developed over time. It is usually expressed as a series of milestones, each with its own Level of Detail/Development/Definition.
