The Fifteen Billion Pound Railway – Documentary on CrossrailBack to Forum
Anonymous23 Jul 2014
Just wondered if any of the UK-based BTers was watching the above documentary on the Crossrail project in London? I caught up on the first episode and it’s absolutely fascinating to see the engineering skill involved (the way they drilled past the escalators was incredible). As a Londoner, it was also great to see what those giant holes are for as I’d been wondering about them for ages but could never see any signage to explain what they were for.
Only thing that struck me was with the Soho House plaster damage – I wished they’d explained why the damage had got so bad given they were using the injection device to try and stop it. Would have been good to be told if it wasn’t working or if they’d left it too late or if the damage was inevitable (and if so, what Crossrail was going to do to fix it and when they’d do it).
Tonight’s episode focuses on tunnelling under the Thames. I had some involvement with London Underground a few years ago so I’m looking forward to this because of the technical challenges.
Anyway, given the controversy about the project I was interested in knowing what other posters here thought. 🙂

I watched it last night – very interesting, and astonishing how they can lift up parts of the Square which are subsiding.
I got the impression that the monitors showed the movement, and so the work was done to prevent any further damage.
Just a point – Soho House http://www.sohohouse.com/ is a members club nearby but it was unaffected – this was the House of St Barnabas, also a members Club, but not-for-profit23 Jul 2014
Am waiting to find out where those millions of tons of “London Clay” that have been dug out are being disposed of.
And yes Tom high pressure mortar injection is moving/raising buildings!23 Jul 2014
BigDog, it is my understanding that the tunnel workings are being loaded onto barges and are being towed somewhere along the Thames Estuary/East Anglian coast where the spoil is being used for coastal barrier defences in conjunction with producing wet lands for a bird sanctuary. But others may have more up-to-date knowledge.
I shall have to catch up with this on iPlayer upon my return to DoB.24 Jul 2014
Information on Wallasea Nature Reserve that Crossrail is building with the RSPB using the spoil can be found here:24 Jul 2014
