BIM is a strong methodology that took almost 20 years of development to reach its current state (Bargstädt, 2015). This tool is a methodology for sharing information and for communication between all the actors in a construction, and in all of its phases. It is based on a digital model of the work, including 3D views, accessible by software which allows the virtual manipulation of said work. It is thus possible to follow and develop the construction in a tri-dimensional way, which, in turn, enables a timely planning. The use of BIM tools has been driven by architects, engineers and consultants, to improve job performance. Below is a list of opinions (Sulankivi et al., 2010; Kumar & Cheng, 2015; Sulankivi et al., 2013; Azhar & Behringer, 2013) on the advantages of using BIM:

− It works as a common database platform for those involved in the Work, supporting information sharing and avoiding loss of information;

− It allows you to go beyond 2D visualization, enabling 3D visualization in a simple way;

− The time required to obtain detailed results is less than in the manual case, and results can be obtained in seconds;


1.1 Introduction

This study aims to describe a means to minimize risks related to the construction site of the Marão tunnel (built using the Conventional Excavation Method-CEM) by using BIM technologies. The use of this methodology intends to minimize the risk of run-overs/hits associated with the usual tasks in the sites during the whole construction phase of the Work, thus contributing to increase the safety of all those involved.
