    Creating a fully attributed 3D model to satisfy the BIM requirements of a project has become a requirement for many projects due to the BIM Level 2 government mandate. Current BIM software is primarily focused on architectural applications and overlooks the specific requirements of complex and large-scale landscape architecture (LA) and master planning (MP) projects. The talk will outline how we developed a script for Civil 3D to add additional attributes to C3D and AutoCAD objects; Surfaces, Blocks and Solids, the challenges we faced, and how we approached them. The class will follow our workflow on a 200 ha site for a major event, where we used C3D to create a BIM model for LA, lighting, and signage elements, importing them into Navisworks for clash detection and collaboration with other disciplines, such as civil engineers and architects. We will also cover the fundamentals of what attribute data was required, the rationale behind the choices, and how we managed data drops.

    Key Learnings

    • Understand the challenges facing landscape architects and urban designers in a BIM environment
    • Understand the process involved in developing attribute data, applying it to objects, and exporting it
    • Understand the workflow used to deliver a large-scale landscape project in a BIM environment
    • Understand the collaboration process undertaken
