What does a BIM object contribute to the project?
If we talk about a generic object, we can say that it provides information of a product (more or less exact), however, when we talk about a brand object we can say that it provides information and additional Identification of the author or manufacturer capable of providing the product in the future.
The prescription of a generic product is useful at an early stage of the design (LOD 100 or even LOD 200). After this phase, a generic object has a limit to the contribution of data and qualities to the project, in which case it is necessary replace it and incorporate a brand object. This is so, because when th eproject goes into constrution there is no other choice and products and materials of the “real” market have to be bought, and this entails buying recognized brands and even white label (behind a white label there is a company that has to answer for that product).

The value of information of a Brand BIM object.
We can say that the brand object is the virtual representation of the product as it is in reality (this from a construction point of view and not from the production of the product). With this we can predict and check how the product will be and what behavior it will have once construction is undergone.
From the BIM brand object we can distinguish two situations at the same time; the first would be in the case that we incorporate a quality (in information and graphics) BIM object and the second when we incorporate a BIM object without quality (unstructured information, inaccurate information, without data, falsified, excess file weight, too much detail, etc).
Quality BIM objects
It is a work tool that accelerates decision making. The quality BIM object, provides reliable information (Remember that the highlight of BIM, is the “I”, of information) and this sets the object for its incorporation into the project.
To get a more accurate idea, when we buy any product, if we are diligent we will read the product labeling (unless we have previous experience with it) and we will see if it responds to the needs we are looking for, or not. In other words, the labeling gives us information to make the decision to buy. The same happens in a virtual environment; based on the information provided by the electronic file we will know if it responds to the needs we need to cover for the project.
Información básica requerida
However, there is another topic that conditions the quality of the BIM object specified in the project. It is the “technique” that the professional applies when incorporating it. If it is done correctly, better data and representations of the project and better calculations can be extracted. To make an incorrect inclusion of the BIM file would be wasting the potential of data and its usability by other professionals.

BIM objects without quality
The consequence of including a low quality BIM product file is, from a technical perspective, a bad experience for the professional that prescribes it since this file generates more problems than benefits (as it is an anti-BIM). The result in this case, is that the file does not provide useful data to the project, and the professional ends up discarding it either because it is inaccurate or because it generates problems in the main project file. On the other hand, the impact of brand image is negatively affected for the professional, since it associates the brand with a low quality BIM file.
Another drawback of prescribing a low quality BIM object, is that, if a quality control filter has not passed regarding its applicability and information, it will end up prescribing a product that is inaccurate for the purpose pursued in the project, and this will undermine the desired result (errors and costs overruns). In this sense the BIM Manager or BIM Modeler must have due diligence and responsibility to detect low quality BIM objects and discard them before they enter the execution process, this is called Responsible Specification.
Let us think for a moment that we prescribe BIM objects without quality (without knowing if it works correctly or not), then we buy the product and place it in the project, after a while we begin to see that the prescribed product does not contain the necessary quality and this manifests itself with cracks, breaks, dispense, etc. A damage to the property or to third parties is generated that must be answered. In this case with BIM it will be possible to detect which agent has prescribed the product, or if the manufacturer has correctly informed about its product or has been deceived or misleading, or if the prescription of the product has been manipulated at the last moment by replacing the product with another different, and finally who is responsible. The BIM software generates a digital trace, which will become an electronic proof if it is needed in a judicial proceeding.
