Integração projeto-produção no processo de desenvolvimetno de projeto: uma alternativa para melhoria da qualidade no setor de construção de OAE

Abstract

The construction sector presents a historic of problems related to the quality of its products, services and processes. Many researches and initiatives against such problems have been conducted by researchers, professionals and organizations from the wide field covered by this sector.Making use technological innovations, methods and tools adapted from other industrial sectors and experiences gathered from development of the design and execution processes, the construction sector in Brazil has shown progress on the performance improvements, due to efforts undertaken in the last decades, mainly on the buildingconstruction segment.Part of the solutions to these problems points to the need of improvement in the management mechanisms of the design process and the integration between the design and execution activities. This research takes this field for granted, leading the focus to the special art constructions, expression used to kinds of constructions such as bridges and viaducts. The methodology of the case study was used to attend of a large sized viaduct project development in which some basics of the Concurrent Engineering are evaluated in order to improve the quality of the product and also of other processes involved in construction sector. This approach is based on the methods and tools studied on the literature revision; in the specific features of the sector, completed by a research done with the professionals of the bridges and viaducts designs; and also by the analysis of the case studyemphasizing the aspects of the design-production integration in the design process, besides a discussion about the way of contracting engineering services. The case study shows that a bigger integration between design and production using the Concurrent Engineering concepts, has allowed the constructive rationalization and the decrease of the costs in the construction.
