This project covered both the design and fabrication documentation of a steel staircase for a project in Germany. Based on architectural drawings and structural calculation files, the steel system was designed with a focus on structural safety, functionality, and manufacturability. The staircase was modeled in a 3D CAD environment, and all components were detailed for production. Complete fabrication and assembly drawings, along with production-ready files, were prepared to support efficient manufacturing and on-site installation.
