Civil engineering projects
Pier formwork
A series of support piers for an extension of the Amsterdam main railway station. Columns with a height of 9,2m and a ground section of 3,3m x 1,15m.
It was decided to pump self-compacting concrete from below because of the specific situation:
- A perfect fair-faced finish had to be achieved
- Huge quantity of steel reinforcement
- Big pouring height
- Small opening on top
- Concrete pressures over 200kN/m²
