The brief

Design and analyse a precast Super-T girder bridge to Australian Standard AS5100-2017 — the standard that governs bridge design across the country. The work had to hold up the way a real submission would: modelled, loaded, checked, and justified.

The process

Built the girder model in SpaceGass, ran it through the load cases AS5100 requires — dead load, live load, dynamic load allowance — and checked the outputs against the standard's capacity requirements at every stage, not just at the end.

What it demonstrated

Why it matters

This is the kind of check that sits behind every bridge a design engineer signs off on in Australia. Running it end to end — not just the theory, but the actual model and the actual numbers — is what the graduate roles this portfolio is built for actually ask for.
