Delivery and Governance
The main works for the project will be delivered through a single-package, lump sum Design and Construct Contract, awarded to Salini Impregilo-NRW Joint Venture (SI-NRW) in April 2016.
The main works contract, carried out by SI-NRW, will include the design and construction of all major work elements, including the tunnel and civil infrastructure, track, stations and rail systems (such as signalling, communications and power). SI-NRW will also be responsible for some maintenance works for 10 years following completion of the project.
In addition to the main contract, the PTA has also let a small number of forward works contracts. These were limited to:
- relocation of significant identified utility services
- provision of a construction power connection near the High Wycombe portal location
- provision of a fibre optic connection along the existing Midland Line.
The PTA will then be responsible for managing the new rail line once it is operational, via the relevant business units such as Network and Infrastructure, and Transperth Train Services.
