The aim of this article is to list the main causes of delays in Brazilian real estate projects. Based on a literature review, this article starts by identifying the factors that affect construction times around the world, focusing on developing countries. The conditions and difficulties that entrepreneurs and builders face in those countries are probably the same as those in Brazil. Based on this list of delays, a classification and correlation was established, identifying possible causes. This framework was used to perform analytical research in 32 construction works executed in the metropolitan region of São Paulo in the past 7 years. The results showed that although entrepreneurs' interference significantly affects the projects (at least in this sample), the main problems seem to be related much more to internal and organizational issues on the construction site, which are the responsibility of construction managers, than to issues external to the construction environment (rain, soil, market changes, suppliers, customer engagement, etc.). This aspect reinforces the importance of investing in training, planning and control systems and methodologies, even if simplified.
