Wall and Vertical Element Formwork

Design starts from pour rate and concrete temperature, which govern lateral pressure. On a tall wall, the gap between a cautious assumption and an accurate one is several rows of form ties — meaning material, assembly time and cost.

  • Bridge abutment
  • Portal frame strut
  • Bridge pier cap and column
  • Circular and rectangular columns
  • Shear wall and basin

Structural Slab Formwork

From bridge deck to multi-storey building slab, the design accounts for camber, the stripping schedule and the chosen pour sequence.

  • Bridge deck
  • Portal frame deck and thick slab
  • Bridge pier cap and column
  • Commercial and multi-storey building slab
  • Tank and basin slab

Non-Conventional Element Formwork

Complex architectural shapes, vaults, tunnels. When the geometry repeats, custom steel formwork pays for itself quickly. When it does not, we look for the lightest solution.

  • Complex and repetitive architectural shapes
  • Specialized custom steel formwork
  • Vault and tunnel formwork

Multi-Storey Shoring and Reshoring

Reshoring analysis determines how many levels stay shored and when you can strip without overloading the slab below. We also produce slab capacity analysis — typically for crane installation or relocation — and building structural analysis for atypical work methods or sequencing.

  • Multi-storey reshoring analysis
  • Slab capacity analysis (e.g. crane installation or relocation)
  • Building structural analysis for atypical work methods or sequencing (e.g. seismic analysis for temporary shear-wall support)
