Local governments face growing challenges in delivering infrastructure that meets rising population demands, operates within tight budgets, and withstands public scrutiny. While advanced design technologies have transformed major civil infrastructure projects, many councils still rely on traditional, less efficient methods. This paper explores how adopting 3D design platforms can enhance efficiency, collaboration, and long-term asset management.

Tools such as Revizto, Navisworks, and 12d integrate multi-disciplinary inputs into a unified model, automate clash detection, and streamline stakeholder engagement. These technologies reduce rework, cut costs, and improve safety-in-design by embedding compliance and hazard mitigation into the design phase. Transitioning from 2D drawings to data-rich 3D models provides councils with a centralised digital resource, improving decision-making and reducing manual processes.

A key focus is model-based design’s role in post-construction asset management and digital twin technology:

• Accurate Asset Information: Metadata-rich models serve as a single source of truth, enabling precise tracking of component specifications and lifecycle management.
• Proactive Maintenance Planning: Embedded data helps councils visualise and prioritise maintenance based on real-time conditions, extending asset lifespan.
• Digital Twin Integration: Dynamic digital replicas enable performance monitoring, future scenario simulation, and improved community engagement.

Integrating these models with GIS platforms supports geospatial analysis, optimising land use and smart city initiatives.

Case studies highlight scalability:

1. North East Link Central Package (Victoria): SMEC’s digital workflows, including automated clash detection and metadata environments, demonstrate how councils can improve communication, reduce errors, and streamline approvals.
2. Warralily Master Planned Community: 3D models optimised visualisation, enabling better stakeholder engagement and decision-making.

Transitioning to model-based design streamlines compliance, enhances efficiency, and future-proofs infrastructure management, empowering councils to deliver resilient, sustainable communities.
