I have a cut-and-fill civil drawing for a flood-mitigated house pad centred on a 30-acre site, plus two surveyed control points out at the frontage. All spot heights are already referenced to AHD, and the plan shows pad size, design levels and existing ground elevations. I now need that information modelled as a true-to-scale 3D surface and exported as a Land XML file. You are welcome to work in CAD 3D or 12D—either environment is fine—as long as the output imports cleanly back into 12D and is ready for Truflow flood-study validation. Key expectations • Recreate the terrain and proposed earthworks accurately from the supplied drawing, honouring the two survey points. • Maintain all AHD elevations and flood-mitigation cut/fill extents exactly as drawn. • D...
The work starts with a whole-building review, then zooms in on one representative space, and finally brings everything together to show how the environmental systems are woven into the architecture. Scope of analysis First, needs toredraw accurate plans and sections in Rhino and export them to Illustrator to build clear, annotated environmental diagrams. The study then moves on site where I will collect data with lux and sound-meter apps. Grasshopper and Ladybug may come into play if they help illustrate findings, but the emphasis is on measured performance rather than full-blown simulation. Primary focus The core of the brief is thermal performance, with particular attention to: • Heating and cooling efficiency • Thermal comfort levels Lighting and acoustic observat...
