BIM (Building Information Modeling) is a highly collaborative process that allows architecture, engineering, construction project teams to collaborate on the planning, design, and construction of a building within one 3D model. It can also span into the operation and management of buildings using data that owners have access to.
BIM objects, the components that make up a BIM model, are intelligent, have geometry, and store data. This means that if any element is changed, the software understands and reflects the change. This allows the model to remain consistent and coordinated throughout the entire process so that structural engineers, architects, MEP engineers, designers, project managers, and contractors can work in a more collaborative environment.
Levels of Development (LOD)
LOD 100 – Concept or massing model including basic areas and
volumes and orientation
LOD 200 – Generalised systems with approximate quantities, size,
shape, location and orientation
LOD 300 – Accurate and coordinated modelled elements that can be
used to estimate costs and check regulatory compliance.
LOD 400 – Model suitable for fabrication and assembly, with
accurate requirements and specific components.
LOD 500 – Details of how the project has been constructed, for use in operations and maintenance
