How To Explain BIM To Your Grandma
Sometimes it can be difficult explaining what BIM is to non-BIM’ers. Here’s a little story that could help explain BIM to your grandparents, family or even your boss?!?
Grandma: What is this “BIM” thing you always talk about?
Me: Well… [long pause]
“BIM” is short for Building Information Modeling – and er…
Maybe you’ve started a conversation like this too?
I then remembered at high school my Design Technology teacher, Mr Ormrod, taught us about physical prototyping.
In nearly every industry we are trained to prototype a few times before we build the final product.
Me: Well Grandma BIM is kinda like a prototype – a goal of using BIM is to find errors and reduce cost before building.
At high school we even went on a field trip to the Lotus car factory to see some prototyping in action!
This is great but we chose to work in the design and construction industry – not manufacturing!
For us we usually design and then work out all the mistakes during construction.
Rework is included in most pricing and contracts – sometimes at about 30% waste 😱
Can you imagine a contractor building the Burj Khalifa (the world’s tallest building) a few times in a remote location before building the real one in downtown Dubai?
Getting back to the conversation with Grandma:
Grandma: How do you create a prototype for a whole building?!?
Me: Well… [medium pause]
They’re actually digital prototypes.
Grandma: Digital prototypes? How does that work?!?
Me: Well Grandma why don’t I just show you an example of BIM?

Grandma: I see, so BIM is this “Revit” software thing?
Grandma: BIM is just simply a quicker way to create 2D drawings??
Me: Sorry I see that the software demo might be confusing – BIM* is actually so much more than just building the digital prototype.
Once the 3D model is created it can be used for everything from winning a project to analyzing how people would move through the building and from clash detection to automatically generating quantities for estimating construction costs – it’s pretty cool!
Some popular “BIM Uses”:
Grandma: Ok, now I’m a little confused! How do you organize all of this?
I think my Grandma now understands a little more about BIM but just in case you need additional details here’s the answer from the BIM Dictionary:
*Building Information Modelling (BIM) is a set of technologies, processes and policies enabling multiple stakeholders to collaboratively design, construct and operate a Facility in virtual space. In ISO 19650 part 1, BIM refers to the “use of a shared digital representation of a built Asset to facilitate design, construction and operation processes to form a reliable basis for decisions” ISO 19650-1.
The term BIM continues to evolve over the years and is thus best understood as an ‘expression of digital innovation’ across the construction industry and the overall Built Environment.
