Sobre a implementação do BIM na indústria do concreto pré-moldado

Abstract

Civil construction is one of the most traditional sectors of the economy, however new forms of building development are being applied, making processes more profitable and efficient, including precast concrete construction. Nevertheless, despite recognizing its benefits to boost the construction industrialization, this type of industry faces a challenge in its production process, requiring methodologies that help to tackle adversities. Thus, this study aims to identify the main problems existing in the design, manufacture and assembly process of precast concrete structures, in order to present and discuss possible solutions by means of the adoption of Building Information Modeling (BIM). The research has an exploratory nature, with a technical procedure of systematic review by using the adapted application of the PRISMA methodology. The results point to the main fields of constructive flow in which problems are detected: coordination, modeling and management. Among the identified problems, we mention: delivery delays, ineffective modeling systems and unnecessary or inefficient allocation of precast elements. As proposals for solutions, the analyzed articles present: fundamentals use of the BIM methodology and some of its tools related to the coordination between construction processes and employees; creation and use of new methodologies, information and families in BIM programs pertained to the specificities of manufacturing and assembly of precast elements; and use of 4D BIM integrated with tracking systems. It is concluded that the BIM methodology has the capacity to solve problems in the precast concrete industry, by considering its versatility and efficiency.
