BIM (Building Information Modelling) methodology has meant a paradigm shift in the concept of project design and management. It is a leap forward in the evolution towards excellence and the technification of the construction process, like the leap that, in its day, was made with CAD (computer-aided design) systems as opposed to manual pencil drawing. The advantages of carrying out integral projects in BIM as opposed to traditional engineering lie mainly in the fact that we have the precise geometric representation of all the components of the project in a digital, integrated and coherent environment that allows us greater control of the information and its subsequent exploitation in the maintenance and operation phases. Without a doubt, the benefits that BIM brings us are multiple: it saves costs and execution time, improves the detection of interferences and errors, improves processes and allows information to be shared in real time between all the agents involved in the project, combines with other technologies, allows integration with databases for its exploitation in the maintenance and operations phase, etc. BIM is here to stay and is gaining ground in all sectors, being essential to optimise business productivity and not lose competitiveness, but implementing BIM methodology in our production system is a great challenge and it is essential to establish a strategy tailored to the needs of each company. But it all starts when we decide to implement it.
