A teaching-learning experience focused on the promotion of specific transversal competencies (self-learning, efficient oral and written communication and team working) integrated into the curriculum of Bachelor in Industrial Engineering (BIE) is presented. With the aim of reinforcing some traditional lacking aspects in old engineering curricula, some core subjects linked to project-based learning activities have been included in the new curriculum of BIE given by the School of Engineering of Barcelona (UPC). The current curriculum includes two mandatory subjects aimed to the acquisition of professional competencies. Students can choose from a list of fifteen available projects. An example of the type of projects offered on the course is given here. It is an interdisciplinary project combining Mechanics of Materials, Statistics and Engineering Project disciplines. Teaching learning methodology and benefits of the approach followed for promoting professional skills are presented. The final section summarises the main results provided by the experience against conventional activities
