The banana plantation worker, as the main actor in a manufacturing process that provides 35% of agricultural produce in the country, has been relegated to a working field in spaces conditioned only for productive processes, leaving aside the possibility of designing working environments that consider vital aspects in their workplace, such as the correct dispositions of working planes, visual ergonomics and hygrothermal comfort, factors that affect the well-being, health, and productivity of individuals. The Urabá zone, located in the department of Antioquia, produced, according to data provided by AUGURA, 73% of national banana exports during 2013, positioning itself as the biggest banana zone in the country, which is a relevant condition for the development of this research, which starts with the architectural survey, spatial, functional and working conditions of a banana packing plant (BPP) in the municipality of Apartadó, from which analysis benchmarks of the conditions of the banana production process are established, and fundamental aspects for an optimized rehabilitation plan of BPP's are identified. The theoretical framework of the research considers the analysis of the environmental conditions in a warm humid climate, workspace and process occupation areas assessment, study of human factors associated with the stations’ operation, and analysis of ergonomic and dynamic anthropometric conditions. The result of this research is a series of rehabilitation guidelines for BPP's, which influence in the quality of working environments and the productivity of the process. Relevant aspects obtained from this research, will be discussed with the banana producing factories and export companies and those could be projected on production business models, from the architecture, human factors and ergonomic's.
