|dc.description.abstract||Up to this date, the construction sector has barely integrated technological innovation and progressive management, being one of the sectors with low level of productivity and competitiveness compared to the rest of the industrial sectors. This is a common characteristic in all countries, which is surprising due to the economic and social importance that construction has. Until this moment, the traditional methodology of development and management of the construction process did not facilitate the incorporation of sufficiently effective tools to reduce the degree of uncertainty, nor increase the reliability and accuracy of compliance with the objectives in terms of time, cost and quality. Therefore, the need to modernize the construction industry was more than evident, demanding a qualitative leap to a global digital environment, allowing to cover the entire life cycle of a project (from its beginning to its demolition or change of use), promoting the integration and collaboration of all the agents involved in the process. This change in the execution of the projects can be achieved with the new methodology called BIM (Building Information Modeling). However, despite the apparent growth in the adoption of this work tool, it is necessary to understand that there is a large number of people in the construction sector who are not yet informed about new technological advances, and, therefore, are opposed to this new methodology, defending the traditional one. This work aims to inform about the general aspects of BIM and the benefits it brings in the construction sector, as well as the numerous applications available. In this work, the emphasis will be placed on the advantages of this new methodology applied in the rehabilitation sector. Six practical rehabilitation cases were studied, citing the benefits of this new methodology for each of them. You can see with these cases, the numerous applications that BIM system has for this sector. It can be used as a tool to detect errors, thus saving material and labour costs, since it is not the same to detect it in the design phase than in the execution phase. Also, as a visual tool to understand the project in a way closer to reality. Also, avoid misunderstandings with the different agents working on the same project since all work with the latest update of the project thus avoiding the current errors of the traditional system, which must be constantly correcting and modifying the plans for lack of communication... Currently, the biggest problem of buildings and construction in general, are the "unforeseen". That many times, they are simply lacking foresight. As a solution to these unforeseen events, this BIM methodology is born, which allows for more information, more quantifiable data of the building. And the more data we can give the project, we can get more accurate information and closer to reality. The main difference with the traditional methodology is that it gives top priority to the information. Many times, with the traditional system the final cost of the project is more expensive than expected and several times is because the company or person who calculated it, did it wrong. It did not take into account all the data, did not take into account all the necessary information unlike this new methodology. In any case, the BIM serves to better manage the design and construction of a building. All this information will be complemented with a practical case, to demonstrate in a practical way the advantages of using this new methodology. The Revit program will be used, with which I became familiar from the first weeks at the beginning of the present work.
