Use a simple plumb line mark on the formwork with a time log. Or use modern IoT sensors that trigger alarms if the pour rate exceeds your R_max.
Account for localized effects: Pouring methods (pumps, free-fall chutes, tremie), drop heights, and re-entrant corners can cause impact pressures or redistribution; use local reinforcement or blocking where needed. ciria report 108 concrete pressure on formwork
