In construction, the composition costs and forecast are factors to generate uncertainty and, sometimes, lead vague and inaccurate values, which refer to projects incomplete or poorly detailed. This setting can be changed through a three-dimensional model with a large amount of aggregate information, created from parameterized objects.
Its main objective is to assimilate all the ramifications of the project, being: planent, budget, architectural, structural, building installation, operation, construction and maintenance. Such integration gives a model representation of a building which is being held in the more realistic manner possible, idealizing all nonconformities presented at construction site, as well as shorter deadlines for exempt revisions due to errors and interference problems between elements.
According to PMI (2013), at all stages of the work, essentially the initiation, planning, execution, monitoring and control and finishing, are necessary and reliable information available. Currently it is common to separate different parts of the project: architecture, structures, electrical, hydraulic and fire being developed by different teams. BIM technology provides a versatile platform where all this integration takes place in the same central model, where each team can only change its scope, cutting step of compatibility and avoiding subsequent adjustments.
The 2D model contains possible sources of error and accuracy, addition to its time consuming review. With this new tool, it is required more planning and less running. Projects become more determined in their documentation, specifications and budgets, allowing the investigation of failures, delays, errors, waste, among others. This study includes the entire building life cycle: project - construction - maintenance - demolition.
To apply BIM ((Building Information Modeling - Building Information Modeling) the projects is the great advantage of health professionals in this promising scenario in construction.
