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

Back to basics with cut and cover
13 July, 2012
Cut and cover. Bachy Soletanche UK’s director Chris Merridew and business development manager Paul Hodgson get back to basics on the cut part of the method, while Alex Conacher speaks to Bernhard Lindner of Germany-based Peri about the concerns of formwork manufacturers in providing the cover

Primary risk reduction
18 April, 2012
It is notable that many treatises on the subject of project risk management do not pay much attention to the subject of site investigation (SI), even though the gathering of accurate information before a tunneling project commences is bound to decrease risk to a project. Today there is a wide array of techniques available to collect such information and costs that can be balanced favourably against overall project expenditure. Maurice Jones reviews some of these

Grouting supports tunnelling market
24 August, 2011
The principles of grouting to improve the stability of ground around underground excavations has been known for a long time, but greater attention to the basic questions of ‘where?’ and ‘when?’ has led to grouting operations that are much more sophisticated than pumping mortar into the ground more in hope than judgement. Maurice Jones explores some of the more advanced grouting techniques now being used and how they help make more tunnelling projects possible or easier

The work includes tunnelling under waterways in tricky, soft-ground conditions and utilising an existing, but unused tunnel. Maurice Jones reports from Antwerp

From the ground up - to project control
14 March, 2011
What happens when underground construction practice doesn’t follow design theory? How can engineers find out what is actually happening with accuracy to reduce risk? The principles of structural monitoring have been known for many years but technical developments in instruments to test ground conditions in situ have increased reliability and reduced cost to such an extent that the wealth of information available has required new thinking in data handling, analysis and presentation. Maurice Jones checks with some leading participants on how data is now collected handled and used, plus how improvements might come about
