The study investigates the implementation of Building Information Modeling (BIM) in the Spanish construction industry. It highlights that BIM is primarily used in the design stage of residential buildings, with limited application in construction, operation, and maintenance. The research surveyed 548 Spanish AEC professionals, revealing that the majority of BIM users are architects aged 35-49, self-taught and focused on design. The study also notes that BIM adoption is still in its early stages, with professionals estimating it will take 3-5 years to fully implement BIM in projects. Despite the potential benefits of BIM, such as improved design quality, cost reduction, and efficiency, the use of BIM tools in construction and operation stages remains limited. The study also identifies challenges such as software costs, lack of trained personnel, and the need for more awareness and training. The research emphasizes the importance of formal training that covers not only the use of modeling software but also interoperability and project management. The findings suggest that the Spanish construction industry is still in the early stages of BIM adoption, with significant potential for growth and improvement. The study concludes that BIM is important for improving professionalism in the construction sector, but its full implementation requires time, investment, and education. The research also highlights the need for collaboration and standardization in the industry to fully realize the benefits of BIM.The study investigates the implementation of Building Information Modeling (BIM) in the Spanish construction industry.
