The paper presents the preliminary results of an ongoing research project which aims to develop a method for controlling waste on building sites. The main focus of the method is to establish waste control procedures as part of site management on a routine basis, using a pull learning approach and emphasising the principle of process transparency by using qualitative and quantitative data collection techniques. The study also intends to make some contributions for the consolidation of the Lean Construction theory, through the application of some of its principles in practice.
