A design planning and control model for modular construction companies

Abstract Modular construction consists of the prefabrication of modules in controlled environments which are assembled in construction sites. The design process is crucial for the timely definition of modular components. This study aims to devise a collaborative planning and control model to improve the design process in modular construction companies, addressing project complexity and stage integration. The Design Science Research (DSR) approach was adopted, and two empirical studies were conducted in different projects. The model is grounded in the Last Planner System (LPS), being supported by collaborative practices and visual management tools. The results indicated that the model enhanced information exchange, transparency, and shared commitment. Furthermore, the implementation of collaborative meetings, supported by visual tools, improved integration among internal and external design team members, helping reduce inconsistencies and delays in the design process.
