Lean construction involves a set of concepts and principles that aim to increase the efficiency of the construction production process. Transparency is one of these processes, which can be defined as the ability of a production process to communicate with people. The objective of this paper is to evaluate the use of transparency practices on construction sites and identify a set of transparency practices that help reduce construction site deficiencies related to organisation, productivity, and production planning and control. This paper uses the exploratory research method based on five case studies in the city of Salvador-Bahia-Brazil and another case study in the city of Fortaleza in Ceará, Brazil, using document analysis techniques, interviews and direct observation for data collection. The main findings show a low level of transparency practices implemented within the construction sites visited. This indicates a great potential for improvement through using such practices, particularly when compared to the higher level of implementation of such practices found in the case study in Fortaleza. It was also observed that the transparency practices tend to contribute directly or indirectly towards the three expected improvement areas: improved construction site organisation, increased productivity levels and a more efficient production planning and control (PCP).
