Substation

The scope of works focused on the detailed design, review, and update of structural and foundation systems across the outdoor yard and associated substation infrastructure, including:

• Foundations for 66kV and 22kV electrical equipment such as isolators, circuit breakers, and transformers
• Structural support systems for bus supports, capacitor banks, and disconnectors
• Footing design for auxiliary infrastructure including yard light posts and station service equipment
• Control cable trench and drainage pit structural detailing
• Review and update of certification documentation (Reg 126) aligned with IFC drawings

A wide range of structural drawings and foundation details were coordinated and delivered as part of the project.

The project required careful engineering coordination and iterative design refinement due to:

• Multiple equipment types and load cases, each requiring tailored foundation solutions across the substation yard
• Ongoing design updates, including revisions to IFC drawings requiring updates to footing designs and certification documentation
• Coordination across disciplines, particularly with electrical layouts influencing structural positioning and foundation requirements
• Optimisation of footing systems for both heavy and lighter equipment to balance performance and cost efficiency
• Compliance requirements, including alignment with Reg 126 certification standards and relevant Australian codes

We provided a robust and coordinated engineering solution through:

• Development of efficient and standardised footing systems across a wide range of substation equipment, improving constructibility and consistency
• Iterative refinement of foundation designs to accommodate updated IFC drawings, ensuring alignment with final project requirements
• Engineering optimisation of both heavy-duty and lighter equipment footings, reducing material usage while maintaining structural performance
• Comprehensive update and coordination of Reg 126 certifications and structural reports, ensuring compliance and facilitating project approvals
• Close collaboration with project stakeholders to resolve design queries and ensure seamless integration with electrical and civil systems

The final outcome delivered a cohesive, compliant, and constructible structural solution, supporting the successful completion of a complex substation project within evolving design constraints.
