Integrated safety and production planning is known as one of the most effective preventive measures to tackle accidents. It is even more important in high-risk construction processes, referred to as critical processes in this paper. A method to plan critical processes in construction is presented in this study. The method was tested in the installation of a pre-fabricated staircase, which was considered to be a critical process in the construction of a hospital. The proposed method has three stages: data collection on process and product characteristics; development and dissemination of plans; adjustments in the plans after the first cycle of execution. The results point out how safety planning and control contribute to establish safe and unsafe working zones as well as how it makes visible the boundaries between those zones.
