Planejamento da segurança na construção utilizando a modelagem virtual

Resumo

The architects and engineers can incorporate safety and health aspects of construction workers through “Prevention Trough Design” (PtD). This tool aims to integrate decisions of the safety and health at all stages of the development of the project. There is computational support for PtD with the use of virtual prototyping. The objective of this paper is to demonstrate the technical viability of integrating the planning of collective protection systems (SPC) to the schedule using the PtD (virtual prototyping) concept in a BIM-4D model. The research approach was divided as follows: Definition of the chosen SPC design; Elaboration of the corresponding BIM library; Inclusion of SPC in the BIM-3D model; Planning of activities and simulation of model integrating activities related to temporary structures; Identification of opportunities for improvement in programming, especially with regard to site safety. As a result, the deficiencies were detected in programming, such as lack of guard-rails in perimeter of slabs that were being prepared for concreting. Finally, the incorporation the PtD concept is technically feasible and can help builders to anticipate risk and plan safety resource allocations in advance.
