In the contractures and engeneer/architecture office, usually, there are big concernings to avoid interference between all the projects that comprise the edification planing. Thus, it’s necessary to do compatibilizations, that now in the days, most of the times, it’s achieved by the software autocad. Those compatibilizations are necessary, beacuse enable the reduction in the construction cost  in a way that not spend the money with new materials, manpower and rework. However, when the bim platform is used, provides a new experience, like agility in the work group to compatibilibilize with much better quality. This article have a goal to study the cases of the following projects: architecture, structure, hidrosanitary and eletric of a familiar residence program named my house my life, made by federal economic caixa, in software revit, as well as the incompatibilities identification between the projects quoted and the solutions, to make viable a new way of compatibilization to popular projects with better quality. The floor plane of the archtetonic project was inserted in revit software, to start the modeling, serving as the basis for the other projects. It was united in a fale the architectural and structural projects, and separated the hydrosanitary and eletric. The files were entered in the navisworks software to check for incompatibilities between the projects in the report.  The incompatibilities were found between electrical and hydraulic, hydraulic and structural and electrical and structural projects. Therefore, the bim platform is very necessary to identify the incompatibilities quickly and simply.

The population growth fostered several segments of industry, in which one finds among them the construction industry can. In this sense of growth, the construction of houses passed and be considered a fundamental part of the economy of the country, by employing a large amount of manpower besides fomenting a whole chain of suppliers. To boost the construction, the reinforced concrete had a primordial role because with its use it was possible to optimize time and resources, obtaining safer constructions and of better quality. The objective of this work is to demonstrate the use of reinforced concrete in the structural systems of buildings, observing the different normative criteria in relation to the understanding of the design and dimensioning of the structures. The paper describes the history of reinforced concrete in civil construction, exposing its evolution that was provided by the technical diffusion of the methods of calculations; presents the reinforced concrete and its components, the structural elements of the reinforcing concrete, the technical procedures for the use of this constructive system. In demonstrating the general aspects of the reinforced concrete and the technical procedures for its use, it is intended to contribute to projects being better observed in their elaboration, so that the specifications and procedures are followed during the execution.

The elaboration of this article occurred after a research in which the comparative analysis of the influence of heating and cooling on concrete strength was studied. For this, tests were carried out in the laboratory, in addition to the concreting of the concrete in concrete mixer, where it was observed that the use of the trace of the material mentioned above, refers to the characteristic resistance of the compression of 25 Mpa. The research also made a comparative study between natural concrete and another that was exposed to high temperatures, in a gas furnace and soon after removed, subjected to a cooling with water, whose objective is to analyze the control and qualification of this concrete. As previously stated, the tests were all done in the laboratory in order to demonstrate the influence at high temperatures and in its instantaneous drop, where a trace of concrete was executed, that shaped 25 specimens of which twelve were made to prove if the trace contains the required characteristic resistance. As the tests were carried out after seven days, twenty-one days and twenty-eight days, it was observed that in all of them, the concrete did not gain resistance, but lost much of it, reaching a reduction of 66.74%. This draws attention to the importance of being aware of the material and its behavior, since a fire in structures such as those analyzed can lead to massive cases of death and material loss. Therefore, it is extremely important to make such an assessment, to avoid possible tragedies.

This article is inserted in the scope of construction planning, and it sought to compare construction techniques aiming at their best cost benefit, seeking to achieve efficiency and economy for the project proposed and maintaining the quality of the service. It is of utmost relevance to understand more deeply the various execution procedures provided by engineering because they tend to clarify the pros and cons of the project, which is essential for the decision making process. This work aims to carry out a comparative study between two technologies of formwork performance, using metallic and wooden materials. The study was carried out through the application of these technologies in the planning of the construction project of the Teaching Pavilion of the Military School of Belém, Pará, using a reference pricing list from the Secretariat of Public Works of the State of Pará. The study analyzed the labor cost, the material and the total value of each construction technique as well as their respective execution time. It was verified that the wooden formwork presented greater viability, representing an economy of approximately 14% in relation to the metallic formwork for the project aforementioned. Therefore, for the case analyzed, the wooden formwork proved to be more viable, reducing the construction cost by approximately R$ 130,000.
