| Résumé: | The Plan of Construction Operations (PCO) subsidizes the fulfillment of the cost, term and the expected quality of the work. These have a direct influence on the productivity obtained at the construction site, since information flaw from the generated documentation is interpreted as the main cause-and-effect factor associated with low productivity, waste of materials and workmanship, resulting in poor quality of the final product. The use of Building Information Modeling in civil construction has been proposed as a technological solution for such problems. When BIM is associated with PCO it is recurrent to use the term 4D BIM or 4D modeling. In this way, this article seeks to clarify how to develop the use of 4D BIM for PCO and what benefits and difficulties arise. The issue was addressed through a Systematic Literature Review. Activity sequencing was identified for the development of BIM-based PCO and associated tooling. The main difficulties encountered were associated with the implementation process and the laborious and intense process of 3D modeling required and the disciplined integration with the work schedule. However, 4D BIM for PCO is feasible, showing benefits in providing optimization guidelines for the traditional PCO process, providing solutions for most of the problems inherent in the conventional method, as well as contributing to the reduction of rework through interoperability, integration of communication systems and simulation of the construction process. |
