Until the structure can safely resist groundwater uplift, often well beyond the excavation stage. That point comes from the structural design, once enough of the structure is in place to resist uplift with the required margin, so ACTION agrees switch-off with the programme engineer.
ACTION designs and operates dewatering systems for the full duration required. AURA, ACTION’s Unified Real-Time Assurance layer, predicts where intervention is needed for as long as the system runs. AURA signals; qualified engineers decide and act.
