Crossrail shortlist for Connaught Tunnel and Pudding Mill Lane jobs revealed

Crossrail has shortlisted four teams for both the Connaught Tunnel refurbishment and the Pudding Mill Lane Tunnel Portal with Vinci making the cut on both jobs.

The four shortlisted for the C315 Connaught Tunnel package – worth between £25 million and £100m – are:

  • Vinci
  • Hochtief/Murphy
  • BAM Nuttall
  • VolkerFitzpatrick/Barhale

The bidders for the C350 Pudding Mill Lane Tunnel Portal – thought to be worth in excess of £100m – are:

The invitations to tender for both contracts will be issued next month with the contracts awarded next year.

To deliver the Crossrail branch to Abbey Wood, a major proportion of the construction work involves reusing disused rail infrastructure including the Connaught Tunnel on the former North London Line branch to North Woolwich and disused National Rail tracks to Custom House – which both closed to passenger traffic in December 2006.

The Connaught Tunnel is around 550 metres long and runs between Royal Victoria Dock and Royal Albert Dock close to London City Airport. The tunnel dates back to 1850.

Crossrail will be enlarging the existing tunnel to accommodate Crossrail trains and overhead line equipment.

Around 100 metres of tunnel wall will be removed and will be replaced with a new tunnel lining. The existing brick arches, part of the tunnel approaches, will be retained and repaired.

Pudding Mill Lane will be the second tunnel portal for the main running tunnels will be constructed. The other tunnel portal will be located at Royal Oak. Preparatory work at the Royal Oak tunnel portal site got underway in January 2010.

Crossrail tunnelling activity will get underway in 2011. Tenders have been received for main tunnelling contracts C300 (Royal Oak to Farringdon) and C305 (Limmo to Farringdon) and are currently being evaluated. Bids for the third tunnelling contract C310 (Plumstead to North Woolwich) are due to be received this month.

Meanwhile tenders for the four station tunnel contracts at Bond Street, Liverpool Street, Tottenham Court Road and Whitechapel will all have been submitted by the end of September.
