What is BIM?
Building Information Modeling (BIM), also known as “information modeling for building” is the digital representation of the physical and functional characteristics of an installation during its life cycle.
BIM is a resource that generates all the information about a construction taking into account the geometry of the building, the spatial relationships, the geographic information and the quantities and properties of the components used; It defines from the earliest conception to its demolition.
When we think of BIM, we often think of better design coordination and the construction process. But the real value can come after the delivery, when the owner or the administrator of the installation receives all the information of the same in full. Even more so, BIM provides an interrelated information system. For example, the model objects are linked to information provided, including manuals, specifications, commissioning data, photographs and warranty details. This allows the owner or administrator of the facility to efficiently and accurately manage the property. Since 75% of the cost of an installation is incurred after delivery.
BIM: A radical change for the construction sector
In the early stages, where the project evolves and is being generated, the BIM methodology helps us easily extract floors and sections from a single 3D model. This model is the germ of the project and thanks to the different screens, it allows us to understand the different proposals of the client and our own team, and all that in real time.
Due to the importance of the implementation of the project in its place and its adaptation to the environment, it is valuable the information that we can obtain about the energetic evaluation of the building. In this way, they are generated from the initial comparative phases of different sustainable solutions, allowing us to select the most appropriate from the conceptual phase. For this, the BIM model is used to study the optimal orientation of the rooms, the amount of solar radiation and the lower environmental impact (6D). If necessary, we can export the model to specific tools that complement the information obtained from the native model.
Phases of the BIM Methodology
Phase 1: Design
With the BIM method, we design your project digitally to know its aspect, execution time, cost, environmental impact and maintenance before building it.
The client can visit his project with virtual reality glasses and change all those details that he does not like before starting the construction.
This intelligent three-dimensional model allows us to:
- Save time and money
- Anticipate and resolve possible errors before starting to build.
- A more detailed planning of the phases of work and necessary resources.
- Draw up plans for manufacturing, execution and subsequent maintenance.
Phase 2: Off-Site Industrialized Construction
From this digital model we elaborate the manufacturing plans with cutting-edge technology.
We manufacture the elements that make up the building in our factory for subsequent transfer and assembly on site.
The % of prefabrication of the project varies depending on the location of the building and its typology.
When making the production at the same time as the works of adaptation and foundation of the land we improved the delivery time by 50%.
Phase 3: Transportation and Assembly
The building is transported to its final location for assembly.
The pending works on site are the minimum required by the project and do not usually last more than 3 or 4 weeks.
The final delivery of the building, completely revised and in operation, takes place in record time.
The coordination of the design team begins to gain importance in the intermediate stages. From the beginning, domains and the ability to modify the different design elements of each team member must be managed. BIM model and an open environment, allows several design teams to simultaneously design different parts of the project, without interfering and streamlining the process.
Some unique elements require special attention during the development of the projects. For this, we can see the design options thanks to the use of parametric tools. With them we can investigate and compare in detail alternatives that allow us to choose the most convenient solution for our client. These tools are used to develop facades, finishes and even unique elements in the interior design phase through the use of interoperable formats we can design exclusive and unique furniture that adds value to the proposal.
At the time of preparing the documentation of the work, the use of the BIM methodology ensures the correct coordination between the three-dimensional model (3D), the two-dimensional plans exported to various formats (2D). Also, the use of model screens – with specific applications for mobile devices – allows a much more complete and updated reading of the project. This information is always available to the work team and the client. Finally, we can also export the IFC file model to the measurement and budgeting programs (5d) and also the simulation, planning and construction management (4D) to complete the information we can extract from the model. Once the project is built, the BIM model can continue to be used to carry out the integral management of services and maintenance of buildings (7D).
The BIM methodology is definitely not a technological transformation by itself, it is not a software, it is a change of mentality. Interoperability in complex processes has become essential in the market, the traceability of actions and the inherent responsibilities of each participant in the development is essential for the proper functioning of the project. The client’s access to all the information in a simple and practical way in real time, is nowadays possible and desirable.
