As architectural design projects tend to tackle larger scales and become more complex, multiple involved actors often need to work from different remote locations. This increased complexity impacts the digital design-to-fabrication workflows that become more challenging, as each actor involved in a project operates on different software environments and needs to access precise fabrication data of specific design components. Consequently, managing and keeping track of design changes throughout the design-to-fabrication workflow still remains a challenge for all actors involved. This paper discusses how this challenge can be tackled through both Speckle, a complete open source data platform for the Architecture, Engineering and Construction (AEC), and SpeckleViz, a custom web-based interactive Activity Network Diagram (AND) built upon Speckle. SpeckleViz continuously maps data transfers across design and building processes, enabling the end-users to explore, interact and get a better understanding of the constantly evolving digital design workflows. This is demonstrated in this paper through a computational design and digital fabrication workshop conducted at the Centro de Estudios Superiores de Diseño de Monterrey (CEDIM), during which an integrative, file-less collaborative design workflow has been set through Speckle, connecting different Rhino-Grasshopper sessions acting as discrete computational design pipelines.
