The use of prefabricated building systems has grown in several segments of the construction industry, especially in emerging economies, due to the need of reducing project duration and costs, improving safety, and dealing with the shortage of skilled labor. Most companies that operate in this market are engineer-to-order (ETO) organizations, in which there is a need to integrate the planning control processes concerned with design, manufacturing and site assembly. One of the approaches used to address these issues is to adopt hierarchical levels for planning and control, in which there are order confirmation points considering the lead-time of some tasks. The aim of this research project is to propose guidelines for integrated production planning and control in ETO prefabricated concrete building systems. It is based on two case studies carried out a leading company in this segment in Brazil. The research method involved interviews with different stakeholders, participant observation in planning meetings, and direct observations in two construction sites. The main contributions in this study are related to enhance the integration between plant and site assembly. Also, use of 4D BIM simulations for analysis of physical flows and evaluate and control the assembly process.
