## 1 Introduction  
One of the main objectives of the architecture, engineering and construction (AEC) industry is the constant need to produce more efficient workflows, contributing to increase the quality of the final product and reduce cost. To achieve a high level of efficiency, the use of new digital technologies, which have been introduced in the sector, is necessary in order to facilitate communication and to avoid repetitive and exhaustive tasks that cause inconsistencies and productivity loss [1]. The traditional way of using Computer Aided Design (CAD) tools, based on digital drawings, requires a great volume of manual work, and it is susceptible to misunderstandings and irregularities. As referred by [PERSON] et al. [2], the evolution of the construction industry is associated with the continuous implementation of new technologies. However, it needs to be supported by new technologies that can embrace digital construction by transforming the construction industry into a dynamic environment. The natural evolution has given rise to a new and more complex generation of building design tools that incorporates advanced modelling technologies [3]. Building Information Modelling (BIM) methodology has been implemented in the sector, with recognized benefits registered worldwide. In recent decades, it has contributedto the agility of the project development, replacing the CAD traditional design process. BIM concept is based on the generation of a digital three-dimensional (3D) model, containing the information related to all project disciplines, in a centralized and accessible database, allowing an easy data sharing among all collaborators. Modelling buildings in fully parametric 3D BIM systems offer numerous benefits in terms of productivity, the ability to quickly generate design alternatives at different levels and the reduction of errors of inconsistencies between the design drawings [4]. In this perspective, BIM has revolutionized the collaboration and data sharing processes in the AEC sector. However, the knowledge about what BIM is and what are the potentialities of it, is still not enough disseminated. Nowadays, around the world there is an agreement that BIM is not just software. BIM is a methodology supported in an integrated and collaborative platform that allows professionals to generate and maintain a data enriched source, easily accessed to perform all life-cycle processes, concerning design, construction and building occupation [5]. Currently, BIM is considered as the process of creating and using digital models, braced on the use of advanced technologies based in parametric objects, for design, construction and operations of buildings. The BIM process involves participants from the entire project life-cycle sectors (architect, engineer, contractor, owner or facilities management) that contribute to create, update and manage the BIM model. The model contains a well-organized database of the virtual building, providing a centralized and integrated source for all information associated with the building designing and performance [6]. The BIM adoption promotes collaboration and an accurate detection of inconsistency at the design stage, which naturally leads to less effort and lower costs associated with eventual corrections. Although this methodology is promising, there is still some resistance to its implementation, not only due to the high investment that offices have to make in equipment, software and training, but also due to the knowledge restrictions that still exist in the use of the available BIM based systems [7]. The present study intends to bring some charity and knowledge to this limitation. BIM is a leading technology for AEC practices playing an important role in facilitating projects, delivery through a 3D virtual model with information associated. It allows a real-time track of the project adjustments and progress in different stages of the building life-cycle [8].
