The construction industry has faced major changes in the last few decades including a reduction in profit margins, the government’s requirements for quality management certification and an increasing level of quality demanded by consumers. Moreover, intense competition between companies has stimulated interest in developing innovations in managerial systems, seeking to improve product quality while reducing its cost. Recent studies have pointed out a category of waste, called makingdo, which occurs when a task starts before all inputs are available. There is evidence that this type of waste is closely related to the execution of informal packages, and that it is the root cause of other types of waste in construction, such as accidents, material waste and rework. Integration between production control and quality management has been pointed out as a means to reduce the incidence of informal packages and, hence, making-do. This type of integration needs the support of information technology, due to the amount of data that needs to be processed by the same person, and also the need to synchronize the application of some controls. Hence, this research study explores the use of information technology in production control systems. A control model was devised and tested in a Brazilian construction company involved in the development and construction of low-cost housing projects. The control model was implemented in one of the company’s construction sites, where a set of quantitative and qualitative data were collected, including making-do events, the occurrence of informal work-packages, project completion and quality control indicators. The paper will present some production control data that were produced in the empirical study, as well as a preliminary assessment of the model that was devised.
