Although BIM methodology is not a current topic, there are still companies that resist its use, believing that it is an expensive investment with no potential for return.
The truth is that, very soon, this will not only be a necessary investment, but a mandatory one, since many countries have adopted the use of this methodology, and some public bodies have already started to demand that projects be presented in BIM format.
If you are just entering our blog and getting to know about BIM, you must be wondering what sets it apart from other methodologies. When we talk about BIM, we talk about Building Information Modelling, that it is a methodology that goes far beyond 3D drawings.
We can understand better from the following examples:
In CAD format, we draw the walls with lines, because we know that it is a universal language to represent walls, doors and other elements present in the project. However, they are just “lines” if we do not manually assign the information.
We only see a 2D drawing, with only length and thickness information. All other data such as area, materials, heights, and so many others that we can collect from a project, in this case they need to be assigned manually.
This technology is effective, but very susceptible to human error. It is recurrent to have flaws in the compatibility between an architectural project and hydraulic projects, for example, in addiction to quantitative errors that imply the final budget of the work, precisely because it depends directly on the human handling of information.
On the other hand, projects developed with BIM methodology allow a wealth of immediate information from the technology itself:
Through BIM technology, the professional builds the project virtually, managing to extract all the quantitative and metric data, prepare budgets, plan deadlines, the project life cycle until the completion of the work. Through this tool, it is also possible to reference geographic data, manage suppliers and employees responsible for each stage of the work, among other features and data.
From the modeling of an element, the user will automatically have the model information in detail. We talk about information such as coatings, materials, and dimensions.
Thus, any change made to the project, the platform will automatically update the data provided. Below is an example of some data provided by modelling a wall:
In addition to all the data management features, BIM also offers the possibility to visualize the project in 3D format in a way that is compatible with the current construction result.
3D modelling allows the professional to identify in “reality” the result of its construction, and facilitates the identification of possible divergences in the project, allowing for early decision-making. This will reduce the execution time of the work and the future increase of the work budget.
Now that we have discussed the main differences between a project developed with traditional tools (with 2D results), and a project developed with BIM methodology, there is no doubt that the process of adapting to this technology will increase more and more.
Companies will save time and money and become more efficient in the execution, communication, and development of all the processes of a project.
As we increasingly live with the concern of being a sustainable world, it makes sense to talk about the contribution of BIM to the result of more sustainable works. The use of this method will result in a reduction of waste and the extension of working time, which cause an increase in pollutant gas emissions and the degradation of the environment.
