Livestock Gate CAD Design & Documentation

I am looking for an experienced mechanical designer / CAD engineer with practical experience in livestock gate / steel gate fabrication.

I need a 3D design and technical documentation for a welded steel animal gate system, based on my dimensions and reference image.

### Scope of work:
- design post A
- design fixed section B
- design movable section C
- section C must open on hinges and slide telescopically
- design the wall-mounted steel closing plate / bracket
- adapt the design to the existing concrete step / wall condition
- prepare the full 3D model
- check loads on wall / concrete / mounting points
- select suitable steel tube sections / profiles / materials
- prepare production drawings with dimensions in mm
-
### Important:
- I already have a reference image / 3D concept showing how the gate should work
- all dimensions must follow my provided measurements
- I need a practical fabrication-ready solution, not only a concept

### Deliverables:
- 3D CAD model
- production drawings
- mounting details
- material / profile selection
- basic load check
- PDF + source CAD files

Please apply only if you have real experience designing gates, welded steel structures, or livestock barriers for fabrication

This will be part of a fencing system for heifers weighing between 200 kg and 600 kg—we’re basing the load calculation on this range.
I’d also like a report on the load calculations, even if it’s just a photo, so I can be sure of the quality of the calculations.
