The report utilizes clear charts and tables to derive coefficients ($C_1$, $C_2$) based on concrete temperature and cement type. For a site engineer or temporary works coordinator, the workflow is logical and easy to follow. The pressure diagrams (showing hydrostatic head vs. the design envelope) visually explain why the pressure is calculated the way it is.
For normal internal vibration (the standard for most construction), the characteristic maximum lateral pressure is given by: ciria report 108 concrete pressure on formwork
