Saikei Civil — Native IFC Roadway Design for Bonsai BIM

Saikei Civil is an initiative to bring professional roadway design capability to Bonsai/IfcOpenShell. The goal is to add tools, features, and functionality to Bonsai that will enable BIM-type modeling of roadways (and eventually other horizontal infrastructure), making use of the IFC 4.3 schema. This proposal aims to deliver the core tools for roadway design in 3 milestones: Vertical alignments (horizontal already implemented), Cross-section profiles, and Corridor generation. Once complete, Bonsai will be the first program capable of roadway model authoring natively in IFC, eliminating massive time and effort toward export processes, and will prevent large amounts of data loss from said exports.
