In this paper, we present Joint Descriptive Model (JDM). Concepts and tools that support an integrative design procedure are missing. 2016) and therefore the fabrication and assembly strategies as a whole. This requires multiple iterations of the design, particularly in the case of timber structure where slight changes of the geometry significantly impact the connections that constitute a decisive part of the structure (Willmann et al. This is because all the stockholders are not known initially, in addition to other aspects such as administration or tendering that do not get decided until later stages. In a large-scale project, it is very difficult (and often impossible) to have an overview of different components, fabrication techniques, and logistic considerations during the early design phase. While these parametric models can provide an extensive overview of the design, the seamless translation from design model to fabrication files to assembly instructions is still limited to research and academic fields, where the global design parameters are known in advance (Stehling et al. Complex structures can then be described with an exhaustive parametric model that breaks down the complexity into several separated relatively simple elements and becomes more manageable. Simultaneously, digital fabrication machines’ proliferation is pushing toward an uninterrupted chain from the design-to-fabrication process (Beorkrem 2017). With the rapid advances in computer-assisted design tools and parametric modeling in architecture designing and manufacturing, and assembling buildings with complex geometry is becoming more accessible, especially within the timber construction field. Finally, we suggest a seed of a joint’s library with some common joints. Based on this, we introduce a comprehensive descriptive language called Joint Descriptive Model (JDM) that leverages industry standards to convert a joint into a usable output for both fabrication and assembly simulations. We developed a workflow that allows us to identify the fundamental data to describe a given joint geometry, machine-independent fabrication procedures, and the assembly sequence. This paper introduces a novel approach to timber joints design that embed both fabrication and assembly considerations within the same model to avoid mistakes that might cause delays and further expenses. Complex architectural topologies require thorough planning and scheduling, as it is necessary to consider numerous factors such as structural stability, fabrication capabilities, and ease of assembly. Joints design is an essential step in the process of designing timber structures.
