Desenvolvimento de orçamento de custos via BIM 5D integrado com a elaboração de projetos e cronograma em BIM 3D e 4D: um estudo de caso

Abstract

This paper has as its main goal, to develop a cost estimating of a popular home in BIM 5D environment, run simultaneously and seamlessly with project design (3D BIM) and schedule (BIM 4D). The cost estimating was made on a specific module of an ERP named SIENGE, based on a schedule and on a 3D model, developed by other authors, mentioned throughout this paper. The Sistema Nacional de Pesquisa de Custos e Índices da Construção Civil (SINAPI), was used as a database for this budget, both for inputs, services and compositions, as in the adopted prices. The project`s quantity takeoff was made by the author directly from the 3D model, through the Revit program, from Autodesk. The quantities were inserted on the budgeting schedule on SIENGE. With the budget concluded, in the own ERP, it was generated the synthetic budgeting reports, as well as reports from the ABC curve of inputs and services. The generated budget served as support to performing a 5D simulation, where a project`s evolution time lapse 3D video was made, showing its correspondent cost at every moment.
