The quality of data<\/strong> and collaboration <\/strong>is 90% of what makes a BIM methodology work.<\/p>\n\n

Data<\/strong><\/h2>\n\n

Data is like cells in the human body – just as the body is made up of cells, the BIM model is made up of data.<\/p>\n\n

A BIM model is made up of a lot of data
<\/p>\n<\/div>\n<\/div><\/div>\n\n

<\/div>\n\n

And the data content is fundamentally determined by three factors: <\/p>\n\n

    \n
  1. the BIM objectives<\/strong> set at the beginning of the project<\/li>\n\n\n\n
  2. the information needed<\/strong> for each project phase<\/li>\n\n\n\n
  3. classification<\/strong> of data.<\/li>\n<\/ol>\n\n

    What does it mean?<\/p>\n\n

    For example, a BIM objective<\/strong><\/a> might be to use the model to feed the FM software that will be connected later (7D BIM<\/a>), to simulate the entire construction process (4D BIM<\/a>), or to be able to query the entire project cost in real time based on the model data (5D BIM<\/a>).<\/p>\n\n

    To achieve the desired BIM goals, we need to be able to collect the right data and incorporate it into the model at the right time.<\/a><\/p>\n\n

    Not too much, not too little.<\/p>\n\n

    On the one hand, data management requires a lot of design, management, and engineering man-hours, which is very expensive, so it is important to avoid including unused data in the project<\/strong>, only the needed data.<\/p>\n\n

    Of course, this also requires that the planner and the client, and in general the stakeholders, do not misunderstand each other<\/strong> at all – the importance of EIR, BEP and the Common Data Environment (CDE) is discussed in this article<\/a>, while the importance of the model’s information content<\/a> (LOIN) is discussed here.<\/p>\n\n

    This will provide the information needed to serve the project properly at every stage.<\/p>\n\n

    But we can only search, incorporate and use data properly if it is properly classified<\/strong><\/a>. It is useless to have a large amount of data, but with a non-uniform, incomplete or poorly managed dataset, our problems (data exchange, data maintenance, coordination, automation, communication, etc.) will only increase <\/p>\n\n

    So the data provides the framework for the project, but for it to work, the elements need to work well together.<\/p>\n\n

    Cooperation<\/strong><\/h2>\n\n

    Think of the body again: even if we have all the cells to perform the functions, they need to work together to make our bodies work well. And not just any way: it would cause a lot of problems if our neural pathways only knew part of what they were doing, or if our hands instead of our feet were activated by a misinterpreted command. <\/p>\n\n

    The quality of collaboration is so important that the market specifically classifies BIM projects into different quality levels<\/strong>.<\/p>\n\n

    \u261b BIM levels<\/a> represent the collaboration between project stakeholders – this shows how “mature” the BIM workflow is.<\/p>\n\n\n\n

    As the cooperation between the different actors increases, the more efficiently and integrally the information content of the model is used. <\/p>\n\n\n\n

    The different BIM levels and their characteristics are summarised in this article<\/a>.<\/p>\n<\/div>\n<\/div>\n<\/div>\n\n
