How geometry, tolerances, transport and erection strategy define steel details in infrastructure projects.
Control complex geometry
Horizontal and vertical curves, crossfall, skew and bearing levels make bridge geometry complex. The model must remain aligned with project coordinates.
Tolerances and connections
Workshop tolerances, surveys and erection gaps must be assessed together. Segment joints and temporary stability elements depend on the erection method.
Model the erection sequence
Access, transport limits, crane capacity and traffic management can govern segment size. Detailing must describe not only the finished structure but also how it will be assembled.
