A perfect storm 30 October, 2015 The UK pipe jacking industry is in a sharp, albeit brief slump. Several factors have come together to make what was supposed to be an end to the rollercoaster of water work, into a complete halt in activity. Alex Conacher reports.

Fit for purpose 30 October, 2015 An expanded concrete lining was suffering in void-filled, desiccated Lambeth Group geology, before London Underground intervention to re-line the operational tunnel with SGI saved the day. Alex Conacher speaks to LU’s lead tunnel engineer and CDM designer/coordinator Neel Goorvadoo.

Can someone please explain exactly what is SCL? 30 August, 2012 A speedy and uncomplicated method has fallen prey to overdesign and endless codes. David Hindle, partner of OTB Engineering speaks out on the present state of SCL design in the United Kingdom

Advances in SCL design and construction 30 August, 2012 This article presents the state of the art use of sprayed concrete with a variety of waterproofing solutions on major projects in the UK. It discusses the current design of permanent sprayed concrete and sprayed waterproof membranes and how SCL design may progress in the future. Report by Andrew Pickett and Simon Stephenson of Mott MacDonald

Crossrail planning dock breakout 16 July, 2012 When Crossrail took over the ancient Connaught Tunnel as part of its route through east London, it was envisaged that it would be brought up to standard with a fill and re-excavate procedure, but further site investigations led to concerns that will now be tackled by open excavation through the Royal Docks

And Claus Mayer, managing director of Nordseetaucher gave an account of his experiences with HPCA

Power up the future 17 May, 2012 UK gas and electric power network operator National Grid is engaged in a major renewal programme to ensure power supplies for the future. One aspect is to install high-voltage cables underground to renew the grid in major urban areas, starting with London. Maurice Jones visited one of the current tunnel drives in a 32km-long network that started recently in north London

The drive to save on light energy 17 May, 2012 Lighting is a key factor in minimising transport tunnel operating costs whilst maintaining or improving safety. New designs of low-energy, low-maintenance luminaires promise much, but equally important is how they are installed and used. Maurice Jones checks out some of the latest installations

Tunnelling induced settlements in London clay 20 April, 2012 Robert Mair of Cambridge University, Jamie Standing of Imperial College and Keith Bowers of London Underground presented three papers on the effects of settlement in London Clay at a joint meeting of the BTS and British Geotechnical Association in January

Getting to the core of the matter 19 April, 2012 Since there still seems to be a marked reluctance in many quarters to spend much on site investigative work before main tunnel construction commences, it is fortunate that drilling, probing, sampling and testing methods are gradually becoming more efficient in terms of speed, accuracy and, hopefully, cost. However this demands a much higher level of sophistication in the technology employed. Maurice Jones checks on what is available

Crossrail countdown 17 April, 2012 With the first Herrenknecht TBM launching as T&TI goes to press, Alex Conacher takes a look back to site visits in early February as segment production had just begun, and the machines were being assembled in the west London mud
