Road grading was modelled on the Development Application (DA) design. Orion then undertook checks to ensure Austroads compliance, making any necessary adjustments.
For the stormwater design, Orion carefully considered staging of works, coordinating with existing and future development, ensuring the system would operate during all stages of development.
The client’s simultaneous development of building product for each lot alongside civil plans preparation necessitated a focus on lot benching and retaining walls. Orion ensured model alignment with the client’s design brief, adding value by incorporating floor slabs to match the proposed site product.
An obstacle arose with traditional drawing methods that can lack a genuine 3D perspective and be time-consuming for client reviews. Orion resolved this by providing the client with a simplified viewer version of the 3D model, offering a clear depiction of the site’s grading. This on-demand export approach saved Orion unnecessary drafting time and allowed the client to review the model at their convenience to ensure it met their expectations
The development included creating a new T-intersection by extending Hambledon Road to connect with the existing Garfield Road East formation. Garfield Road East falls under TfNSW jurisdiction, with long-term plans to elevate the road above flood levels. Meanwhile, Hambledon Road’s design, funded by SIC (Special Infrastructure Contributions), is under council control. Orion’s task involved documenting the intersection upgrade, necessitating substantial coordination with TfNSW and Blacktown City Council to ensure the intersection complied with the council’s Hambledon Road design, the future upgrade for Garfield Road East and coordinating with existing road formation, all to limit the extent of required temporary works.
