BIM 1D, 2D, 3D, 4D and 5D CAD explained

The Computer Aided Design (CAD) software application ranging from one to 1D to 5D CAD is a dynamic process and when integrated provides a true realisation of the Building Information Model (BIM) process. This 5D CAD is the future of the Architecture, Engineering, and Construction industry (AEC). To further explain  this process see explanation below:-

1D CAD which involves the program data.
2D CAD involves a design base upon the data that was program
3D CAD involves data intelligence and linking of a database to generate BIM
4D CAD involves the scheduling and sequencing of construction process
5D CAD involves the cost and resources to complete the project.

Details on 5D CAD


The benefits derived from the 5D CAD process are as follow:-

  • Data integration and tracking
  • Quick analysis
  • Graphical integration
  • Architect, Engineer and Construction processes combine into single environment
  • Coordinating the designs and the construction work by real-time updating process.
