BIM and CAD represent two fundamentally different approaches to building design and documentation.

CAD (Computer Aided Design) applications imitate the traditional “paper & pencil” process in so far as two-dimensional electronic drawings are created. Lines, hatches and text, etc., are created independently from each other so design changes need to be followed up and implemented manually on each CAD drawing.

BIM (Building Information Modelling) applications imitate the real building process. Instead of creating drawings from 2D line-work, buildings are virtually modelled from real construction elements such as walls, windows, slabs, roofs and the complete range of engineering services elements etc. This allows Architects, Structural and Building Services Engineers to design buildings in a similar way as they are built. Since all data is stored in the central virtual building model, design changes are automatically followed-up on individual drawings generated from the model. With this integrated model approach, BIM not only offers significant productivity increase but also serves as the basis for better-coordinated designs and a computer model based building process.


BIM encourages and promotes a collaborative approach to solutions by forming the central framework through which all parties can come together and integrate the differing disciplines, systems and components.

The model becomes a common project through the whole design and construction team affording shared problem solving and design development.

Ameon’s Engineers are fully trained and experienced in the use of BIM software products such as Autodesk Revit, Navisworks , 4p, Buzzsaw etc allowing 3D BIM Modelling of projects for Design, Construction and Building user operation and Maintenance Instructions.
