Chuquicamata Underground is one of Chile’s most significant mining infrastructure projects, where complex underground conditions require close coordination across multiple teams, disciplines, and construction processes. For ACCIONA, managing this complexity meant transforming how information is shared between the field and office. Dalux provides a common digital environment where teams can access up-to-date project information, coordinate activities, and manage quality and control processes in real time. Activities, inspections, and controls are linked directly to specific project locations, keeping documentation, evidence, and approvals together in one place. This gives teams greater visibility of construction progress, improves traceability, and supports faster, more informed decisions. By making Dalux part of everyday workflows, ACCIONA has strengthened collaboration between teams and established a more connected and structured approach to managing complex underground construction.
