BIM is an acronym for Building Information Modelling, a design activity which uses 3D computer modelling technology such as Revit to create a shared knowledge resource that supports collaboration between the various design disciplines, owners and other stakeholders in a construction project.
BIM has also been successfully applied to infrastructure and other construction projects that are not buildings! BIM models provide accurate geometry plus sufficient data to support construction, fabrication, and procurement needs and can even be used to support ‘Facilities Management’ functions throughout the building’s lifetime! CADS customers that that have adopted or utilised BIM say the benefits include scheduling, estimation and risk analysis, more collaborative processes and improved communication between all those involved. Indeed BIM provides a unique opportunity to prototype and even ‘virtually construct’ the building before committing to site thus avoiding many of the cost problems and delays that were previously considered to be an intrinsic and inevitable part of the construction process.
The experienced team at CADS can deliver your design faster and at a lower cost than traditional design methods allow. Our unique ability to connect SCIA Engineer 3D FE design software to Revit and back means we can take full advantage of existing design information, collaborating fully with our clients or the in-house design team at CADS.
BIM levels of development
LOD 100 – Concept design
The building 3D model is developed to represent the information on a basic level. Thereby, only conceptual model creation is possible in this stage. Parameters like area, height, volume, location and orientation are defined.
LOD 200 – Schematic design
General model where elements are modelled with approximate quantities, size, shape, location and orientation. We can also attach non-geometric information to the model elements.
LOD 300 – Detailed design
Accurate modelling 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 400 – Fabrication & assembly
Model elements are modelled as specific assemblies, with complete fabrication, assembly, and detailing information in addition to precise quantity, size, shape, location and orientation. Non-geometric information can also be attached to the model elements.
LOD 500 – As-built
Elements are modelled as constructed assemblies for maintenance and operations. In addition to being accurate in size, shape, location, quantity, and orientation, non-geometric information is attached to modelled elements.
