Metro viaduct design — substructure to drawings

One engine, end to end

From alignment to BOQ.

One model carries the whole viaduct — scroll through the workflow.

01 · STRUCTURAL

Substructure to superstructure, parametric.

Change a parameter — chainage, span, soil, load — and the model regenerates. Stations share the same model.

02 · LOADING & VALIDATION

Every combination. Every check.

Analysis-integrated. Forces, stiffness, geotech, ULS & SLS — validated before review.

03 · REAL-WORLD CONTEXT

Alignment, against the terrain.

Geo-referenced terrain catches sight-line, corridor and ROW conflicts before drawings.

04 · DRAWINGS

2D drawings, from the model.

Sections, elevations and plans auto-derived. Dimensions and schedules update with every change.

05 · OPTIMISE & COST

Live BOQ, alternatives, savings.

Rebar curtailment and configuration trade-offs. BOQ tied to your rate book, updated live.
