All dimensions of BIM
Over the course of the year we have explored some of the dimensions of BIM, but how many are there, and above all what do they refer to?
Let's see in detail every single dimension of BIM, from 3D to 7D, also including the new dimensions not yet regulated.
WHAT ARE BIM DIMENSIONS
BIM is not a simple 3D model of the work created or to be created. We can in fact consider it a database, complete with all the information relating to the entire life cycle of the work, from the conceptual design phase to disposal.
In this database the information is carefully sectorized by theme and each theme is managed within its specific dimension.
Each dimension therefore concerns a specific aspect of the project, for example timing, management costs or facility management.
At the moment the
Italian (UNI 11337) and European regulations recognize the dimensions
of BIM from 3D to 7D , let's see what they concern and what are the
new dimensions that we are starting to talk about.
THE STANDARDIZED
DIMENSIONS
- 3D BIM
3D BIM concerns the digital, three-dimensional model of the work, which contains all the information on its geometry and is practically identical to the real construction. With 3D BIM it is possible to:
– See the project in its entirety even before its construction;
– Make changes to the model in advance, saving time and money. - 4D BIM
The 4D dimension deals with the analysis, organization and management of project timelines. Allows:
1 | Analyze the progress of activities in real time;
2 | Automate the processes that allow this;
3 | Coordinate work more effectively;
4 | Optimize times. - 5D BIM
5D BIM is about cost management of the entire project. From the early stages, with 5D it is possible to make an accurate estimate of the costs of the entire life cycle of the work and save on costs by quantifying the specific prices of each individual component and process included in the project.
- 6D BIM
(In the European BIM 7D regulation) BIM 6D defines the Facility management of the project, i.e. its management and maintenance throughout its life cycle. Contains all information relating to systems and components, maintenance manuals, warranties, specifications etc.
- 7D BIM
(In the European BIM 6D legislation) BIM 7D is the dimension that deals with the sustainability of the project, analyzes its performance and evaluates the impact this has on the surrounding environment, in order to improve not only the energy but global performance of the project. 'building.
THE NEW DIMENSIONS,
FROM 8D TO 10D
In addition to these,
recently we are starting to talk about three new dimensions of BIM, which are
not yet regulated and which are still being debated: 8D, 9D and 10D.
- 8D BIM
8D BIM is related to everything that concerns workplace safety on construction sites. Thanks to this dimension it is possible to create a digital model of the construction site in which:
– Predict the risks that may exist;
– Define the actions to be carried out to prevent accidents;
– Carry out a scenario analysis to eliminate any type of criticality. - 9D BIM
When we talk about 9D BIM we are talking about Lean construction, an approach that digitizes processes and monitors the management of raw materials, allowing you to save time and money and avoid waste. - BIM 10D
BIM 10D concerns construction in its entirety and takes a step further than previous dimensions, working on the industrialization of construction, i.e. on the centralization of data and the use of new technologies to speed up and improve the processes of the construction sector.
