Project
In Perth, Western Australia, the PTA Sutherland St. Load Upgrade project is helping modernize the city’s electrical infrastructure to support its growing public transport system. APD Global is responsible for the engineering and detailed design of a new 132/22kV Bunning Lake switching substation, which is critical to enhance the electrical supply capacity and reliability for the Public Transport Authority. The project aims to support the growing demand for electricity in the area and ensure a stable power supply for public transport operations. APD Global is delivering the full spectrum of multidisciplinary engineering and detailed design for the 132/22kV Bunning Lake Substation. The project is currently in the construction phase and the expected to complete in 2027. APD Global uses Bentley software to coordinate across disciplines, reduce design errors, and ensure compliance with safety and performance standards. This initiative is a key part of Perth’s strategy to build a more resilient and efficient energy network.

Solution
To overcome the challenges of fragmented workflows, limited visualization, and inefficient collaboration, APD Global adopted Bentley’s suite of integrated digital tools for the project. The team used MicroStation for detailed design and drafting, ensuring precision and compliance with engineering standards. OpenUtilities Substation supported utility network design and visualization, streamlining the planning of complex electrical systems.
iTwin Capture was deployed to gather high-resolution reality data, enabling the creation of accurate 3D models that reflected existing site conditions. This data was processed using Bentley Descartes, which allowed for advanced point cloud modeling and seamless integration into design workflows. These tools helped align civil and structural elements with electrical infrastructure, reducing errors and improving coordination.
Bentley LumenRT helped create digital twins with immersive real-time visualization, making it easier to communicate project scope and progress to stakeholders. This enhanced understanding and alignment across teams. The use of ProjectWise ensured a single source of truth, facilitating real-time updates and collaborative reviews.
Together, these tools enabled automatic report generation, reduced manual errors, and minimized site visits. The digital-first approach improved efficiency, reduced material waste, and delivered a high-quality design that met all stakeholder expectations.
Outcome
The adoption of Bentley technology led to a 15% reduction in both design time and overall project completion time, translating into significant cost savings. Material waste was reduced by 1% to 2% through clash detection and optimized design. The project’s digital workflows improved collaboration across disciplines and minimized risks of delays and rework. Enhanced visualization and reality modeling ensured accurate alignment with existing infrastructure, while reduced travel and site visits contributed to a lower carbon footprint. Ultimately, the project delivered resilient and sustainable power infrastructure that supports Perth’s growing public transport needs and improves quality of life for its residents.
