Crossrail’s first fully assembled TBM
in each station to create an integrated line-wide identity. This design work encompasses wall and floor finishes, lifts, escalators, lighting and signage suitable for use in all the new stations. This sys- tematic approach will create a unified look, max- imises value for money and yet allows each station to retain its individual identity. To develop and test designs for the under-
ground station platforms, a life-size ‘mock-up’ of a below ground Crossrail platform has been created. The mock-up has been built to help Crossrail understand how the new designs for new below ground platforms will look in real life and to determine from a practical perspective whether any design modification needs to be made ahead of station construction commencing. The mock-up will help inform final design deci-
sions about the below ground station environment. It is critical that Crossrail gets the internal design of stations right as the new stations have been designed to last for the next one hundred years. The mock-up of the Crossrail platform section is
life sized, measuring 20m in length, 10m in width, with a ceiling height of 5m above the platform- edge doors. It also contains a 4m long side-tunnel entrance providing entrance and exit. The mock-up has been created using film set
design techniques to replicate the feel of actual finishes, which are significantly cheaper than using actual construction materials.
Construction update Construction of Crossrail’s western tunnels between Royal Oak and Farringdon is being undertaken by a UK joint venture comprising BAM
Nuttal, Kier Construction and Ferrovial Agroman – the UK subsidiary of Spanish multinational Ferrovial. Over 150 people are currently employed at the Westbourne Park site. Andrew Wolstenholme, Crossrail's chief exe-
cutive said: “Crossrail is an infrastructure project of national significance. Tunnelling for the major new rail tunnels under London will get underway in just one month from now. Over 3,000 people are now employed on Crossrail with thousands more to be employed at the height of construc- tion. Contracts worth £3 billion have been awar- ded to-date providing a much-needed boost to the UK economy. At least 90 per cent of all Crossrail expenditure will be invested within the UK. Further high-value contracts will be awarded later this year including the main construction contracts for Liverpool Street and Tottenham Court Road stations.” The first Crossrail TBM is due to undergo
testing ahead of the start of tunnelling. Work is well underway to re-assemble the second TBM that will launch from Royal Oak Portal in April. Next month, the first TBM will be launched into
one of the twin bores at Royal Oak Portal tun- nelling east towards Farringdon. A second TBM will subsequently be launched in April through the second bore. At over 140 metres long and weigh- ing around 1,000 tonnes the TBMs will travel 6.4km (4 miles) eastbound under London via Paddington, Bond Street and Tottenham Court Road before reaching Farringdon in 2013. This will be followed later this year by the
launch of a further two TBMs from Limmo Peninsular in the Royal Docks that will travel a
Whitechapel
total of 8.3km (5 miles) towards Farringdon via Canary Wharf, Whitechapel and Liverpool Street. Towards the end of 2012 another two TBMs will
begin construction of the South East section of the route, launching from Plumstead portal in the South East and travelling a total of 2.6km to con- struct the Thames Tunnel. Two TBMs will also be used to create nearly 3km of twin-bore tunnels between Stepney Green and Pudding Mill Lane. A total of eight tunnel boring machines (TBMs)
will construct 21km of new twin-bore tunnels (42km in total).
