**5. Conclusions**

This bibliometric approach can meaningfully contribute to the ongoing manual review of BIM. Conference papers are the main source of scientific publications, followed by scientific article and reviews. Experts and researchers mostly contribute to expanding BIM literature through these channels, and the rest are published through book chapters, conference reviews and article publications. The scientific contribution in this study refers to 4307 articles associated with BIM, where only 6.4% of these articles related are to BIM in universities and 46% is published in just three countries, which are the USA, UK, and China. The bibliographic records provide users with necessary data about the affiliation of di fferent articles. Furthermore, four out of sixteen universities are present for both of the research topics BIM and BIM in universities. Georgia Institute of Technology and Pennsylvania State University are the leaders in this emerging area of research. It is also observed that the countries that made the usage of BIM mandatory in the regulation of construction are the ones which have the most interest in researching and developing this concept. The five clusters obtained in BIM research are those of the cycle in which all phases related to the construction industry are found: construction management, documentation and analysis, architecture and design, construction / fabrication, and operation and maintenance (related to energy or sustainability). However, the clusters of the last phases such as demolition and renovation are not present, which indicates a field that still needs to be developed and researched. With regard to the evolution of research, it has been observed how information technologies have been integrated with IoT. Finally, a key factor in the implementation of the BIM is its inclusion in the curriculum of technical careers related to construction such as civil engineering or architecture. Therefore, in order to remain up to date and meaningful, education in construction needs to take advantage of the opportunities and overcome the challenges presented by BIM. This bibliometric analysis provides a general overview of the subject in order to concentrate on the strategies that are still relevant and to open up promising new lines of research. This work opens new perspectives for the use of the BIM in universities, which has been found to be less extensively covered than BIM at a global level.
