O autorze

Alun Thomas is an independent tunnel designer and the founder of All2plan Consulting ApS. Having graduated from Cambridge University in 1994, he went on to work for several major design companies with a short stint working on site for contractor. Alun has a broad experience of many types of tunnelling methods from immersed tubes to segmental linings, from closed face TBMs to hand excavation under compressed air. He is a recognised expert in sprayed concrete lined (SCL/NATM) tunnels and numerical modelling, having completed his PhD at Southampton University in those fields. Alun has been involved in promoting the use of innovative technologies such as permanent sprayed concrete, fibre reinforcement, GFRP rock bolts and spray-applied waterproof membranes. He has been involved in many of the recent major UK tunnelling projects such as the Jubilee Line Extension, Heathrow Express, Thameswater Ring Main, Terminal 5, Victoria Station Upgrade and the Elizabeth Line (Crossrail), as well as working on design and construction of tunnels internationally. Alun has been an active member of several industry bodies, notably participating in writing guidelines for BTS, ITA and ITAtech technical committees.
