Crossrail has started the hunt for a contractor to carry out £401 million worth of M&E and power line work in the main tunnel sections.
The 70 month “C610 Systemwide main works” project covers a range of packages for work principally between Westbourne Park, Pudding Mill Lane, and Plumstead.
- Track and overhead line electrification - the design and installation of standard track slab, ballasted track and OHLE installations. Installation of employer’s designed floating track slab,
- Mechanical & electrical installations - the design and installation of the M&E installations, including tunnel ventilation. This contract will also provide an installation service for cabling for others,
- Logistics services - logistics services would include the provision and management of railheads and works trains, including trains for other contractors,
- The contractor will also act as the principal contractor for works in the tunnels and on open route sections.
Construction of Crossrail’s tunnels will get underway in spring 2012 when the first tunnel boring machine is launched from Royal Oak.
By late 2014, the construction of over 21km of twin-bore tunnel, stretching across the capital via central London and Docklands, will have been completed.
The fit-out of the tunnels with will follow before the line goes live in 2018.
This will include the installation of over 40km of track, overhead electric conductor rails to power the trains as well as ventilation and drainage systems.
Crossrail programme director Andy Mitchell said:“As the new Crossrail tunnels are completed, work will get underway to fit the tunnels out with the necessary track and overhead power equipment to enable the railway to operate. Such is the scale and complexity of the task it will take several years to complete the fit-out works with people working around the clock to complete the job.”
The new Crossrail tunnels will also require over 50 ventilation fans, 40km of walkways, 60 drainage pumps, 30km of fire mains as well as lighting throughout the entire length.
The contract will be awarded in late 2012, providing the chosen contractor with sufficient time to undertake detailed design and planning before fit-out work commences in 2014.
