Column Formwork is to be designed to be able to accommodate relatively high fresh concrete pressures as comparatively small cross-sections are concreted quickly. ... Column formwork is comprised of panel formworkelements or based on individual formworkgirders; steel formwork is also available.
Formworks are measured in terms of area. So any unit such as square meter, square foot, square centimetre can be adopted. But generally, square meter and square foot of the contact area with concrete is taken as the unit of measurement.
