Sydney Airport and Port Botany are two of the most important gateways in Australia, facilitating the movement of people and goods in and out of New South Wales. It follows that the transport network around these hubs is one of the busiest in Sydney during peak hours and improved access was needed.
Airport East Precinct included the upgrading of roads east of Sydney Airport and removing the General Holmes Drive rail level crossing by constructing a road underpass.
This project has also improved the movement of rail freight to and from Port Botany.
Aurecon was engaged by New South Wales Roads and Maritime Services as the lead consultant for detailed design, technical design support and environmental impact assessment assessment for the project. The design services covered the roads east of the airport, including General Holmes Drive, Joyce Drive, Botany Road, Wentworth Avenue and Mill Pond Road.
The detailed design services included:
The project area to the east of Sydney Airport comprises critical utilities, rail freight lines, residential and business areas and along with airport related restrictions, added to the complexity of the project.
Aurecon took a digital approach to this challenge, using visualisation expertise and Aurecon Digital Tool siteLab® to bring the project to life. The model produced led to a successful collaborative experience with the client and construction teams.
The interactive model was used on site, communicating several major constraints, including gas, rail, sewer, flood and aerospace, and detailed some of the construction staging of the bridge structure.
