DESCRIPTION:Seminar overview:\nShotcrete (or sprayed concrete) tunnel lini
 ngs are loaded at early age as the tunnel advances. Therefore to construct
  sprayed concrete tunnels safely\, we need to know the current stress stat
 e and the current strength of the lining\, as well as its geometry and qua
 lity\, with the aim of estimating the factor of safety. However\, to appro
 ach the face of a tunnel puts workers at risk of falling ground or fresh s
 hotcrete. This talk will describe a novel method of measuring shotcrete st
 rength from a remote location using a thermal imaging camera and propose w
 ays that this may be incorporated into an automated system for monitoring 
 factor of safety. Along the way we will also discuss technology adoption i
 n the construction industry and finding the right partners.\n\nShort biogr
 aphy:\nBenoît Jones graduated from the University of Bristol in 2000 with
  a First Class Honours degree in Civil Engineering with Study in Europe (P
 olytech’ Grenoble\, France). He then joined Mott MacDonald as a Graduate
  Tunnel Engineer. Between 2002-2006 he undertook research for an EngD at t
 he University of Southampton with Professor Chris Clayton as his superviso
 r\, sponsored by Mott MacDonald and the EPSRC. After working on Crossrail 
 MDC3\, in late 2007 he went to work for Morgan Est (now Morgan Sindall) as
  Section Engineer on the King’s Cross Underground Station Redevelopment\
 , then as Engineering Manager on the Stoke Newington to New River Head Tha
 mes Water Ring Main Extension Tunnel. In Autumn 2010 he joined OTB Enginee
 ring\, a small consultancy specialising in tunnelling and geotechnics\, wo
 rking on temporary works designs for Tottenham Court Road Station Upgrade 
 and for the Crossrail Eastern Running Tunnels (C305). From September 2011
  to December 2015 he worked at the University of Warwick\, where he set u
 p and ran a new MSc in Tunnelling and Underground Space. He joined the Uni
 versity of Cambridge in January 2016 as Course Director of the Constructio
 n Engineering Masters Programme.\n\n
