Steel Step-Over Platform
A modular step-over platform designed for service routes crossing roof-level obstructions. The public-safe model shows the access geometry, guarded stair sections, perforated tread layout, support bases, and bolted assembly strategy without exposing confidential project identifiers.
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.
Key Features
- Adjustable feet with rubber 'Big Foot' floor sockets
