Roof AOV Access Ladder System
A public-safe roof access assembly for Automatic Opening Vent (AOV) maintenance. The model combines a vertical ladder, guarded top access area, support framing, mounting brackets, anti-climb protection, and controlled handrail geometry into a coordinated fabrication package.
Project Overview
This project demonstrates mechanical design and fabrication documentation for industrial use. The focus is on creating a practical, safe, and manufacturable solution with clear CAD modelling, assembly structure, and production-ready drawings.

Engineering Challenge
The engineering challenge involved balancing access, safety, fabrication, installation, dimensional control, component layout, and drawing clarity. Special attention was paid to site obstacles, pipework clearances, and minimizing on-site weldments.
Design Solution
The solution was developed through meticulous CAD modelling, detailed assembly planning, fabrication-ready documentation, and clear communication of components, fixings, sections, and manufacturing requirements. Parametric constraints were added to speed up future revisions.
