In this short video we’re going to introduce the definition of BIM.
Of course there’s hundreds of definitions of BIM out there, this is the definition that I will use consistently across all videos for the BIM Framework.
So, how do we define BIM? The BIM Framework adopts a very general and wide definition of BIM.
It first says that BIM means Building Information Modelling, is not Building Information Model,
like some companies, users and researchers, especially in the US, use the BIM acronym for.
So we’re gonna be using Building Information Modelling.
And Building Information Modelling is defined as a set of technologies, processes and policies, so is not just about technologies and tools and software,
but is also about processes. Also it doesn’t stop at processes and workflows, it also includes policies and protocols and stuff like that.
And these technologies, processes and policies combined, enable multiple stakeholders. So we are discussing really all the supply chain across the whole project lifecycle.
And designers, contractors, operators to collaboratively, together whether by exchanging or interchanging (we’re going to be covering this in the future), to design, construct and operate a facility.
So really, we’re discussing the whole lifecycle here. And when we say 'facility' we don’t just mean a building, it could be a bridge,
it could be an airport and even we could extend it to include some mining facilities, and train stations and other overlaps with other acronyms like GIS.
So, another way of understanding Building Information Modelling is to flip the term:
So, by saying, we’re trying to model information, so we are modelling or shaping, forming, presenting, scoping information with an organized set of data to do something to this building, to that structure.
With this information we are trying to virtually construct a building, or to extend the analysis of it, or to calculate the construction coast of it.
We’re going to cover this in the future on something called Model Uses.
Another aspect of Building Information Modelling, which is very important in order to separate what is BIM, and what is not BIM, is the type of underlying technology we’re using
and we’re always discussing Building Information Modelling as an object-based technology, where we have these typical objects like a column, or a window, or a door being embedded inside a building, which is actually a database.
And while embedding these into a building, these objects are still persistent, they do not dissolve within that building so we can still query them, we can still count then, we can add specifications to them, etc.
So we are really, when we’re discussing Building Information Modelling as a term, we are depending, of course, on using object-based technologies in order to develop, deliver a facility.
Finally, there are five typical deliverables of BIM.
So if we’re using Building Information Modelling tools, workflows and processes and policies, we are expecting to deliver five main types of deliverables.
Of course there are hundreds of possible deliverables, but they fall under five main types.
This is just a basic understanding of them, we’re going to be covering this in more detail under 'Model Uses'.
But if you’re using BIM, you can expect - you don't have to - but you can expect to, get some parametric, algorithmic 3D graphical views.
To get some 2D drawings out of the 3D model and you are expecting to get some scheduling, quantities out of the model and specifications,
and most importantly you are also expecting to get some kind of model-based analyses of spatial design for thermal design, for seismic design, wind studies,
also we’re going to be covering this under something specific called 'BIM Uses' or 'Model Uses'.
I hope this definition makes sense to you. In the future as we add more videos, hopefully all things will look very well connected for you.
