The Cross City Motorway Consortium (and its successor, Cross City Motorway Pty Ltd), was responsible for maintaining performance standards and handing the Cross City Tunnel to its public partner after the concession period expiry in agreed condition (Roads and Traffic Authority 2008: p.25). This arrangement included the implementation and maintenance of an Operation and Maintenance Plan, Operation and Maintenance Manuals and the preparation of an Operations Rail Safety Plan (Roads and Traffic Authority 2008: p.26). The responsibilities of Leighton Contractors (as a member of the consortium) extended to the full maintenance, operations and asset management services of the Tunnel, including the communication networks, mechanical and electrical systems, traffic safety, and the tolling system (Leighton Contractors 2009: p.2). These accountabilities are typically commensurate with concessionaire responsibilities for other such Economic Infrastructure projects and where the public partner has oversight responsibility for ensuring the documentation is complete and remains up-to-date.
