Construction companies are facing nowadays several problems. The lack of projects for construct is one of the problems in the construction sector. With the problem of existing less projects, come high competition between national and international companies for awarding the projects. This competition, leads in many cases to prices given just to award the project. As a consequence many losses occur from this works, which lead to more problems into the company. But, most of the losses occur due the lack of communication and organization inside the organization. There is no collaboration between the teams and the departments. The work processes are done as if the departments were different organizations.

A new approach is emerging in the construction sector, Building Modelling Information (BIM). BIM is praised as been a collaborative tool. However, BIM is still trying to have its affirmation into the construction sector. BIM has revolutionized the design process of the projects with its Parametric Building Design technology. The objects have the capacity to carry information, the models can be visualized in 3D. With BIM, the construction process can be simulated, by adding the time a the costs to the 3D models. A visualization close to the reality can be achieved through these simulations. Many projects were already made by using BIM to support the design, construction and facility management processes along its lifecycle. However very few or none infrastructure projects where yet analysed.

The present work intends to study the information process within construction companies. The idea of this study is to analyse the collaborative feature of BIM to help in the information sharing. Based on the project lifecycle, the construction stage is analysed for information sharing and transference. Since this is a new approach which is starting to be implemented, the organizational and works processes are further studied. When studying BIM, some of the existing tools are analysed. At the same time, based on an infrastructure project, the application of BIM in these type of projects is studied.

Thus, the present work is organized into six chapters. The first chapter, the Introduction, presents the structure of this thesis, the initial ideas and impressions, the problem and the scope of the project. In chapter two is presented the methodology used for doing this work. The third chapter have a approaches the topic of construction management and project management. In this chapter are defined the concepts which are used for analysing the problem. Chapter number four contains the state of art. BIM topic is developed in this chapter by presenting what is it. Also, what has been done so far with BIM and it's level of development are shown here. BIM's history is presented, together with some case studies. The fifth chapter is where the problems are analysed. The current situation, the needs and the possible future solutions are presented in this chapter. Chapter six contains the discussions about the most relevant problems and respective conclusions. This chapter also contains the future perspectives, with some suggestions for future works and research.
