Rate (R)
The magic of CIRIA 108 lies in accurately capturing and Setting Time (E) . Misjudging these is the primary cause of formwork failure.
Dependent on the formwork's dimensions and shape; it distinguishes between walls and columns. cap C sub 2 (Material Coefficient): ciria report 108 concrete pressure on formwork

What is concrete pressure on formwork?
CIRIA 108 is intended for stationary forms. For slipforming, dynamic pressures are higher—consult separate guidance. CIRIA Report 108: Concrete Pressure on Formwork -
Outcome:
The formwork supplier designed ties at 1.2 m horizontal × 1.5 m vertical spacing, versus 0.6 × 0.8 m for hydrostatic. Material savings: 60% less tie hardware, lighter walers, and faster assembly. The pour completed without any deflection or leakage. This project alone saved over £15,000 in formwork materials. The Formula 3
