In the context of construction, BIM or Building Information Modelling is the process of delivering and operating built assets. these built assets are created using well structured digital information which is necessary for all concerned parties to have access to.
Information Modelling/Management is a way of working rather than a physical object or entity.
Working on BIM environment requires all the parties to collaborate and share the information from a mutual space. The space can either be online storage on a web server or it can be locally stored on a shared LAN (Local Area Network).
In this way, anyone from the concerned parties can have easy access to that information.
As you may now know the basic concept of what “BIM” actually is, you may be wondering as what that “BIM” can do for you and why so many people are talking about “BIM”, advocating it?
You have probably heard that lot of people are now talking about BIM, and probably might have heard that it is a 3D modelling software and it costs more.
Usually BIM or Building Information Modelling is applied to buildings, or facilities, and it may also be applied to other things like infrastructures and GIS (Geographical Information System) applications.
Using BIM, you can really build anything in the built environment that has a physical form and meaningful data.
Any particular group or certain purposes does not defines BIM.
It is not just for design, construction, or operation. Neither it is limited to design analysis, clash detection, or facilities management, nor it is just for buildings, infrastructures, or GIS. BIM can be used to educate, to inform in contracts, to create VR (Virtual Reality), and for disaster planning too.
The reason you use BIM software and processes is to improve the efficiency and quality of the work you do and are responsible for.
BIM can be used for anything, and you can actually work out how it could benefit what you do. It is an important aspect of BIM processes where each participant is benefiting and will be more powerful to have greater take up, and longevity.
To overcome the less efficient and less accurate methods, BIM is something you can do.
You don’t draw on CAD and model it in other CAD softwares, you don’t manually create data in tabular format or create a table in Microsoft Excel anymore, you can now easily create them on Autodesk Revit.
You don’t do structural design by linking an analysis package to your model and calculate it all out with a pen, paper, and a calculator.
You don’t use a BIM model and a total station to set out ceiling hangers and measure them out with a measuring tape.
You don’t have a room full of project drawings and project folders, now you can have an integrated database of project drawings and folders.
This also applies to management. BIM is a tool to get things done, it is not a thing in itself.
Here are some benefits of BIM.
- BIM reduces rework,
- BIM improves productivity,
- BIM reduces conflicts and changes during construction,
- Clash detection can be done and rework can be avoided,
- Multi-disciplinary collaboration can be done using BIM
Evolution of BIM implementation came in parallel with willingness to collaborate and share project information, the move toward integrated practice that is much talked about in the industry. – Philip G. Bernstein.
