In fact, very often a task is considered to be completed in short-term control, but no quality checking has been performed. The aim of this research work is to propose a model for production control that integrates task completion and quality control, with the support of Information and Communication Technologies (ICT). It is built on a previous version of the model, which was strongly based on the Last Planner System ® . Thus, the model was further developed and tested through the use of commercial software packages, which has also enabled the use of BIM for visualizing control data. Besides monitoring quality conformance and the completion of tasks, the model can also be used for measuring some types of waste, such as making- do and unfinished work. Two empirical studies were developed in construction sites located in Brazil. In this paper, some of the results obtained from the instantiation of the model are briefly presented, as well as some suggestions for future research on this topic. KEYWORDS Production control, quality control, unfinished work, informal work, making-do. INTRODUCTION Despite the advances in production planning and control that have been achieved by the adoption of Lean Production ideas in construction projects, especially by the dissemination of the Last Planner System ® , few efforts have been undertaken by the Lean Construction community in order to improve the quality of the final product during site installation (Leão et al. 2014; Rocha 2015). 1 Civil Engineer, Master Student, Building Innovation Research Unit (NORIE), Federal University of Rio Grande do Sul (UFRGS), Porto Alegre, RS, Brazil, josevillamayor86@gmail.com 2 Ph.D., Professor, Building Innovation Research Unit (NORIE), Federal University of Rio Grande do Sul (UFRGS), Porto Alegre, RS, Brazil.
