THE Australian Government-owned company, WSA Co, has announced its procurement strategy for the construction of the $5.3 billion Western Sydney Airport at Badgerys Creek in Sydney's west, which will require 22 million cubic metres of earth to be moved, one million square metres of airside pavements and 30 kilometres of landside roads to be constructed.
There will be three packages of work, with the first and largest encompassing first stage earthworks and utilities and airside pavements. Expressions of Interest for this first package are due to be released in February 2018, with a view to contracting a preferred tenderer in the first quarter of 2019 and for works to commence early in the second half of 2019.
The second major package will be the terminal building and associated airside and landside interface works. The third package will include the landside roads, carparks and associated works.
Together, these packages comprise the Main Works program. WSA Co is already procuring the Airport Enabling Works program, with geotechnical investigations and land survey services recently released to market.
A number of smaller specialist packages, including IT, security and baggage handling systems, will be put out for tender separately and integrate with the main works.
"WSA Co is committed to delivering a world class airport and this decision is essential to achieving that objective by 2026. This strategy allows WSA Co to procure the best expertise that the private sector has to offer," said WSA Co Chair, Paul O'Sullivan.
WSA Co has also signed a contract with the manager and operator of the NSW transmission network, TransGrid, for the relocation of the high-voltage transmission line that currently crosses the site. As part of the contract, TransGrid will relocate the existing 3.2-kilometre section of aboveground high-voltage transmission line to an underground cable route wholly located within the airport site.
The first stage of Western Sydney Airport project will deliver a 3.7-kilometre runway and a terminal with capacity for 10 million passengers a year. It will also include cargo facilities, maintenance areas, a public transport hub, car parking and areas set aside for business parks.
When the proposed airport opens, it is expected to service around five million passengers a year – about the number of passengers that use Gold Coast Airport today. After around five years, this could grow to 10 million passengers each year.
The proposed airport is expected to be progressively developed as demand increases beyond 10 million passengers a year. The need for a second parallel runway would be triggered when demand approaches 37 million passengers annually, which could occur around 2050.
