The Port Authority of New South Wales sought to create a dynamic digital representation of their physical assets across six geographically dispersed ports, accessible to multiple departments and stakeholders to improve collaboration, decision-making, and operations. Their previous, static, file-based system lacked spatial context and trusted data, taking days to compile requested information. To accommodate the voluminous, multisourced data and ensure they retained accurate, high-fidelity engineering information, they needed to establish a connected utility network and single source of truth.They selected ContextCapture to create accurate 3D reality models of the port sites, and OpenCities applications to establish a GIS and digital twin platform accessible to users for remote asset inspection. Using Bentley technology streamlined workflows and reduced travel between ports, optimizing collaboration and accurate data sharing among departments and stakeholders, which is expected to save 50% in time compiling data requests. The digital twin solution provides a holistic asset view spanning multiple lifecycles, increasing data transparency, eliminating redundancy, and promoting community engagement and collaboration with environmental and marine agencies.
