This paper aims at proposing a method of Knowledge Management in project documents to acquire and integrate data, information and knowledge. Exploratory, descriptive and propositive research was conducted in documents of different projects run by the Transportation and Logistics Laboratory of the Federal University of Santa Catarina, Brazil. The method encompasses 22 phases and three gates for the analysis of the continuity of the base building process. The results contribute to the reuse of project knowledge by interweaving data, information and knowledge to facilitate future management and collective learning. Finally, this paper suggests the development of intelligent systems for automatic and dynamic knowledge mapping in project documents as well as for its electronic sharing. Such systems would provide fast search to support decision-making and optimization of efforts expended in future projects through the reuse of good practices and lessons learned.
