Considering the industrialized manufacturing process of mass timber structures, an issue that is constantly mentioned in the literature is the failure of communication between design and manufacturing. Consequently, there are greater material waste and a more complex and time-consuming assembly than it would be necessary. Therefore, the problem addressed in this paper is the search for optimization of CLT (Cross-Laminated Timber) and Glulam (Glued Laminated Timber) structures regarding the construction process of these technologies. The authors propose to determine indexes to quantitative measure the structural shape, as a result of the architectural shape, concerning the rationalization of the construction process. To do so, initially, the research aims to identify the variables inherent in the technology's construction process that interfere with the optimization of this process and simultaneously have a direct relationship with the architectural design. The research methodology involved the study of the construction process of the first national CLT manufacturer, as well as two case studies of structures designed, manufactured, and assembled by the same producer. Based on these studies and analysis, three indexes were defined to evaluate the manufacture and assemble process of the structures. It is considered that these should be incorporated from the beginning of the architectural conception, enabling the creation of a structural form aligned with the premises of the technology used. As future developments of this research, these indices could potentially be incorporated into a parameterized digital design tool.
