Work Begins On Crossrail Portal

A Costain-Skanska joint venture has begun work on the initial stage of creating the Crossrail rail route that will eventually traverse London, with commencement of the project to create the tunnel portal at Royal Oak, west of the city centre, next to Paddington Station.

When complete in 2017, Crossrail will offer a new, high-frequency rail route starting at Maidenhead in the west through central London and out to the east, forking to Shenfield, near Brentwood in Essex and to Abbey Wood in southeast London. The central section through the capital will require the driving of major new tunnels under the city.

When entering the tunnel, overground trains will start descending several hundred yards before the portal. It is on this gradient that the Costain-Skanska team at Royal Oak is now working.

The initial stage is to create diaphragm walls on either side of the route. This involves excavating a deep trenched panel followed by creating the wall structure within it.

"The diaphragm wall is pretty much a huge retaining wall, around 200 metres long and around 27 metres deep at its maximum," explained Project Manager, Dr Vicknayson Thevendran. Once the two diaphragm walls on either side of the route are completed, bulk excavation commences between them which is twenty metres wide over the length of 200 metres. You then build a slab at the bottom of it and lay the tracks on top.

"The main problem facing the 100-strong team on the site is extremely tight working conditions. One side of the site is just three metres from the 630-volt live track for London Underground's Hammersmith and City Line, while the other side is bounded by the A40, a major road artery for Transport for London.

"The proximity of other transport links creates complexities when handling the inevitable paperwork. We need to submit every document to Crossrail, Network Rail, London Underground and, on instances where we're close to the A40, we need to liaise with Transport for London."

Work on the diaphragm walling began in late August and is planned to be completed just before Christmas.

Work set to start on Tunnelling and Underground Construction Academy (TUCA)

Work is set to start on a new academy which will give thousands of young people the skills and training needed to kick-start a career in construction after VolkerFitzpatrick was notified of Crossrail's intention to award the contract to them.

Next month sees the start of the new Tunnelling and Underground Construction Academy (TUCA) in east London, which will use Crossrail, Europe's largest transport infrastructure project, to offer training to at least 3,500 people in underground construction alone over the lifetime of the project

Crossrail at its peak will employ some 14,000 people and will provide a crucial boost for London's economy. The Tunnelling and Underground Construction Academy aims to address the shortage of people with the necessary skills to work on Crossrail and other tunnelling projects across the UK.

TUCA will start to offer training in spring 2011 and the building will be fully open by summer 2011. Following the completion of Crossrail the academy will remain providing a lasting legacy for London and the UK construction industry.

The establishment of a Tunnelling and Underground Construction Academy is an important part of Crossrail meeting its commitments to improve skills and create employment opportunities within the industry. It will provide training on the key skills required to work in tunnel excavation and underground construction.

The Tunnelling and Underground Construction Academy will be a purpose-built facility providing training on the key skills required to work in tunnel excavation and underground construction. Whist the UK has tunnelling expertise and knowledge there is not a purpose-built training facility in the UK to act as a focal point for the industry. Currently the nearest tunnelling and underground training centre is in Switzerland.

The Academy will be located at Aldersbrook Sidings on the border of Newham and Redbridge, close to Ilford town centre. Enabling works are currently taking place on site ahead of main construction starting.

Crossrail tunnelling activity will get underway in late 2011. In just over one year from now the first tunnel boring machines will start on their journey from Royal Oak towards Farringdon. This will be followed shortly by the launch of further tunnel boring machines in Docklands that will head towards Farringdon under central London. Teams of dedicated construction workers will be working 24 hours a day to complete the tunnels with thousands of others employed to upgrade the existing rail network and build major new stations along the central section of the route.

Terry Morgan, Crossrail Chairman, said: “As well as delivering much needed additional rail capacity, Crossrail has an important role to play in supporting regeneration and the economy. Ensuring that job opportunities are made available to Londoners - and that Londoners have the skills required - is a vital part of Crossrail's approach to construction.

“Contractors winning work with Crossrail will recruit and employ local people along the construction route and it is likely many of these people will attend training at the Academy. This will ensure that we have people with the right skills in place to deliver Crossrail for London and many other vital infrastructure projects in the future.”

The volume of tunnelling and underground construction work taking place in the UK over the next decade is unprecedented. Aside from Crossrail, Thames Water will be constructing the Thames Tideway Tunnel sewerage scheme while National Grid will be constructing new electricity cable tunnels under London.

Crossrail needs the new Academy to address the shortage of people with the necessary skills to work on construction of the new railway. The Academy will ensure that all people working underground on Crossrail sites achieve the Underground Safety Passport. Crossrail anticipates that 3,500 underground workers will require training of some sort over the lifetime of the project.

To meet the needs of the Crossrail construction programme, training at the Academy will initially be provided to people working on Crossrail to meet the needs of the construction timetable. The training at the Academy will include National Vocational Qualifications such as NVQ Level 2 in Tunnelling Operations. The course content for this is currently being developed.

The Tunnelling and Underground Construction Academy will provide training for contractors working on other major London tunnelling projects, as well as the potential to assist European projects including Dublin Metro. The new Academy will ensure that there are sufficient numbers of people with the skills to work safely in underground construction to satisfy industry demand.

Crossrail will also leave a skills legacy for London and the UK. It is planned that the Tunnelling and Underground Construction Academy will be operated as an independent organisation once the Crossrail construction is complete and become a long-term provider of tunnelling skills to the construction industry.

I've read that the new rolling stock for the Thameslink programme is going to be a template for Crossrail. Does that mean that the Thameslink platforms are being upgraded to handle a non-UK loading gauge?

As for Crossrail, it would be interesting to see a blend of Bombardier's Electrostar and Spacium trains as the rolling stock.

I think you will find that the Crossrail line will be built to continental loading (as a form of future proofing) but the trains will be built to UK loading as the trains will run on existing lines at each end. So no upgrade to those lines and no change to Thameslink.

They need them to keep an eye on the disproportionate ammount of women who use the station.

Oh absolutely. The Metropolitan Police has the ability to monitor every movement of everyone in virtually every street of London thanks to CCTV. It's the most watched capital in the world.

Forget the West End, Crossrail’s real beneficiary is sure to be Farringdon


On the money: development at Tottenham Court Road is well on track but Charles Pinchbeck of Jones Lang LaSalle sees great potential to the east.

“Farringdon” was the answer two experts gave to the question “which location will see the greatest uplift in commercial and residential property prices come 2018, when Crossrail is finished?”

Computer images of the new £1 billion station at Tottenham Court Road were published this week which should allay any fears the 73-mile pronged railway linking Maidenhead with Shenfield might be consigned to the sidings.

If you do have any doubts, go and look at the huge building site paralysing the eastern end of Oxford Street.

The works underway at Farringdon are even bigger. The redevelopment, which embraces the north-south Thameslink line, is so extensive it fills the gap between the existing station and Barbican.

Developers such as Derwent London long ago figured prices around Tottenham Court Road would rise and bought into the area. Farringdon is another story.

“There will be an incredible improvement in the accessibility at Farringdon” says Jones Lang La Salle's Crossrail expert, Charles Pinchbeck. “You will be able to get to Heathrow, Gatwick, Luton and Stansted airports very quickly.”

Second expert, architect Rab Bennetts, is trying to persuade a client to “do something cultural” in the area. “Farringdon will become a new hub,” he predicts. So, are those sneaky developers already piling in? “No, not yet,” says Pinchbeck. Go for it.

Yes, but that's not the choice is it? No one said should we have too much security or none at all.
The Champions League final is televised with fewer cameras.

If they think that's necessary to keep it safe, so it be.

It's possible for security to be too much if it starts disrupting passengers and reducing service for little gain(like the increasing airport paranoia these days), or if it's easily abused. There's also the issue of cost. Personally I think the whole issue of too much CCTV in the UK is exaggerated and overblown by some people, but I can see where they're coming from.

Anyway, I don't know why but that Crossrail render reminds me of the ticket hall at the new Sheperd's Bush station.

How can CCTV disrupt the service?
