BIM Terminology

There are so many different technical terms relating to BIM that it can be difficult to keep track. To make things easy for you, here is a list of some of the most important BIM terms.

3D, 4D, 5D, 6D, & 7D

In addition to 2D and 3D computer-aided design (CAD) modelling, there is also 4D, 5D, 6D and 7D. 3D refers to three-dimensional geometry. 4D refers to construction sequencing information that includes the three spatial dimensions and an additional dimension of time.

5D includes 4D plus “cost”. It integrates design with the estimating and scheduling of costs including labour and productivity rates.

6D and 7D include aspects like sustainability and facility management and other concepts like the Internet of Things (IoT).
