What is the meaning of BIM?

• A. Building Information Modelling
• B. Building Information Model
• C. Building Information Modelling
• D. Building Integrated Modelling

Answer: (C)

BIM means Building Information Modelling, a digital representation of a building that combines its geometry with rich information about every component. It’s not just a 3D model; it’s a process and a shared data environment used across design, construction, and operation so teams can access reliable information about costs, quantities, performance, and maintenance throughout the building’s life.

This is the best answer because it captures both the modeling aspect and the information attached to the model. The other options either imply a single model rather than a process and data-rich environment, or use a term (Integrated Modelling) that isn’t the standard expansion of the acronym. The wording here reflects the common phrasing (Modelling) used in many contexts, while the idea remains the same: BIM is the model plus the information that supports lifecycle decisions.
