Tenders and contracts

We outsource work on state highways to private sector suppliers, including consultants and contractors. We do this on a competitive basis as part of ensuring our investment achieves best value for money.

In this section you'll find information on how we procure these services, as well as upcoming, advertised and awarded contracts, and a summary programme of major state highway projects underway and planned for the next few years. You'll also find information on our contractors' prequalification scheme - including how to register to join it.
