Steel form for AMETI bridge – unique shape with all surfaces curved in 3 dimensions.
Key elements:
- Pier a unique 3-dimensional shape.
- 2 forms to cast a total of 4 Piers.
- Steel plate with intermittent ribs.
- Rebate section removed first after casting.
- Two fluted forms bolted to the rebate section.
- PFS took engineer's design and produced detailed design for forms.
Challenges:
- Steel Plate tad tricky to bend in two directions.
- Numerous design innovations made to achieve practical solutions.
- Bolted Joint between form sections was a channel which twisted in 3D.
- Obround shape fabrication was particularly interesting for form face, ribs, and stiffeners.
- Face of steel was exceptional in achieving high off-shutter concrete finish.
