Level of Development (LOD)

Improve downstream collaboration on your building projects with AIA standard Level of Development.

We enable you to streamline your workflow with BIM and adopting all its parameters; including the AIA specified standards for Level of Development for each component. We create 3D models with and without the non-graphical data add-ons, for the different LoD specifications from LoD 100 through to LoD 400. We have successfully delivered BIM LOD500 solution for a university hospital building as per AIA standards in Saudi Arabia, which reduced their liabilities, wastage of materials, manpower and time.

Level of Development

Level of Development (LOD) for BIM Processes:

LOD 100: Represents a conceptual model where overall building mass is indicative of area, height, volume, location and orientation that may be 3D modeled or represented by other data.

LOD 200: Model is represented as a generic system, object or assembly with approximate quantities, size, shape, location and orientation. Here non graphic information may also be attached to the model.

LOD 300: Accurate modeling and shop drawings where elements are defined with specific assemblies, precise quantity, size, shape, location and orientation. Here too we can attach non- geometric information to the model elements.

LOD 350: LOD 350 includes model detail and element that represent how building elements interface with various systems and other building elements with graphics and written definitions.

LOD 400: Model elements are modeled as specific system, object or assemblies, with complete fabrication, assembly, and detailing information in addition to precise quantity, size, shape, location and orientation. Non- geometric information to the model elements can also be attached.

LOD 500: Elements are modeled as constructed assemblies for Maintenance and operations. In addition to actual field verified representation in terms of size, shape, location, quantity, and orientation, also non-geometric information may be attached to modeled elements.

As the models are purpose built for various stages of design, visualization, scheduling, construction-caliber quantities,, cost estimation, onsite project control and fabrication, they support clients to streamline workflows, gain better control over projects and increase productivity.

Level of Development Vs Level of Detail

A lot of confusion stems from the fact that both level of detail and level of development are abbreviated as LOD. However level of development as defined by AIA is a measure of how seriously you take the information that is represented by a BIM element. Contrary to this level of detail talks about the graphical details, as the level increased the model is more detailed.

Level of development is a concept that refers to the certainty about an object. Hence a model that is meant for a contractor and the one that is developed for a fabricator will have different types of information.
