This paper reports a 6-year experience teaching building information modeling (BIM) methodology in the undergraduate/graduate architecture, engineering, and construction (AEC) program at the Pontificia Universidade Catolica do Rio de Janeiro (PUC-Rio), Brazil. This work is part of the long-term goal of developing a new BIM AEC-based curriculum track for engineering and architecture students at this university. The paper also reports the results of a survey on the student’s perception on how this knowledge has affected their way of working with other disciplines and how it has influenced their professional lives. The adopted approach involved theoretical lectures, computer laboratory practice, student oral presentations, and the complete project of an enterprise. The lectures delivered by specialists with practical experience in the subject exposed the students to BIM concepts. In the laboratory, students were trained in the software tools that enables BIM activity. To develop the project, multidisciplinary teams of students were formed and each team was challenged to emulate the change in process that BIM implies. The task was to develop the complete project of an enterprise considering all different specialties involved in its design, detailing, and planning. More specifically, these specialties consisted of architecture, structural engineering, mechanical and electrical systems, and BIM management. The teams made oral presentations to the client (the professor) and consultants roughly on a weekly basis. In each year, the students´ performance was evaluated in several ways. In particular, a 360° evaluation tool was used, which was crucial to provide feedback to each team member during the exercise. The culmination of this experience is the elaboration of this article that aims to describe the challenges and the successes of the adopted approach.

There has been an increasingly global tendency in the adoption of Building Information Modeling (BIM) paradigm in Architectural, Engineering, and Construction (AEC) projects. At the same time, Structural Optimization (SO) has received a lot of attention in the construction industry to reduce material and to enhance structural performance. However, the lack of communication between structural engineer and architect is a well-known problem discussed in the literature. This can lead to inefficient projects, thus increasing cost and time. The purpose of this work, thus, is to understand how SO can be inserted in a BIM project, specifically analysing the information exchanges between architects and structural engineers, to mitigate the problem related to lack of communication. The investigation included a systematic literature review to comprehend the current scientific scenario in these areas. It identified that there is still a research gap related to the adoption of SO to facilitate the communication between architects and structural engineers in a BIM environment. To help answer this question, an Information Delivery Manual (IDM) structure was developed which maps the information flow to connect architects and engineers through SO in a BIM environment, aiming to optimize the information exchanges. By applying the methodology to three experiments of increasing complexity, the proposed framework proved to improve the collaboration issue beyond other project benefits, such as reduction of material consumption, improvement of sustainability indexes, and structural performance. Thus, the main finding of this study is that the connection between BIM and SO can improve the collaboration between these two players in the early design stages and, thus, it can potentially lead to a more efficient design process. More studies are still necessary to solve technological barriers related to software interoperability.
