Despite the lean construction community criticism of Critical Path Method (CPM), it is impossible to ignore its widespread use. Furthermore, CPM is commonly considered a contractual requirement demanded by owners. On the other hand, Location-Based Management System (LBMS) and Last Planner System (LPS) have been successfully implemented in many construction projects. This article puts forward the proposition that there are synergies between these tools and their combined use could provide great benefits and fill some gaps. The aim of this paper is to propose a practical process for integrating LBMS, LPS and CMP, in an attempt to improve planning and controlling processes in general, besides filling gaps related to delay analysis. A constructive research was developed through a case study, collecting data of a planning and controlling system used by a large construction company, which applies CPM and LPS tools. The processes and the main decisions of the project team were systematized in an integrated model, taking into consideration the project phases. Two additional propositions were formed to be validated in future case studies. Firstly, the integrated sources of data will help professionals to support decisions. Secondly, the schedules created with this integrated approach are better able to model workflow.
