BIM Level of Detail / Development

A BIM’s Level of Detail / Development, LOD, measures the level of refinement of the 3D geometry of the building model. This is used as a measure of the service level required. We create BIM models from LOD 100 to LOD 500. These are described below:

TO BE DEVELOPED

1D BIM is a basic 3D model of the building is created; this allows one to understand the shape and massing of the building and its elements.

2D BIM MODELS
Plans, Sections, Elevations & Schedules

2D BIM incorporates details of all elements of the model sufficient enough to obtain 2D CAD drawings and schedules from the model. The drawings thus derived will then need to be further detailed and coordinated to produce construction information.

3D BIM MODELS FOR CONSTRUCTION
Clash Detection, Walk Throughs, Assembly Sequence Drawings

3D BIM incorporates specific 3D data of the building elements which are coordinated with each other in 3 dimensions to remove clashes, display assemblies or assembly sequences, create walk throughs and produce construction information with little addition of 2D CAD drawings.

4D TIME
Construction Sequencing

A 4D BIM adds an additional dimension of information in the form of scheduling data to various elements of the model. This allows obtaining accurate program visualizations and shows just how the project will develop sequentially.

5D COST
Bill of Quantities & Cost Management

A 5D BIM applies the cost element to the elements of the model. This allows for obtaining accurate quantities and overall cost of the project, which is automatically updated as the model develops. Along the Construction Sequencing this further allows for budget planning.

6D SUSTAINABILITY
Energy Performance of Buildings

A 6D BIM incorporates information on the energy performance of the building elements and itâ€™s systems. This allows for calculation of energy performance of the building at an early stage.

7D MANAGEMENT
Asset Management & COBie

A 7D BIM incorporates asset data such as component status, specifications, maintenance/operation manuals, warranty data etc. This information can be extracted in COBie format to be used outside the BIM software by 3rd party building management programmes and even Microsoft Excel. This allows for easier and quicker parts replacements and a streamlined asset life cycle management over time. The model can be continually updated during the life time of the building to help manage the asset from design to demolition.

BIM Dimensions

A BIM’s Dimensions stipulates the type of information that is added to a building model. We can add 7 types of information to a building model, in other words we can add 7 dimensions of information to a building model. These are described below:

1D CONCEPT
Early Stage Modeling

1D BIM is a basic 3D model of the building is created; this allows one to understand the shape and massing of the building and its elements.

2D BIM MODELS
Plans, Sections, Elevations & Schedules

2D BIM incorporates details of all elements of the model sufficient enough to obtain 2D CAD drawings and schedules from the model. The drawings thus derived will then need to be further detailed and coordinated to produce construction information.
