Millions of Pounds saved by "Flexiarch" on London Underground

Millions saved by London Underground and Bridge Owners through research by QUB team

£80m has been saved since 2008 by London Underground (LU) and yet more by bridge owners in the UK as a direct result of using the Arching Action (AA) enhancements in strength predicted by our research. The associated disruption would have resulted in enormous congestion, losses economically of £ billions and negative social impact. Multi-million $ savings have also accrued in North America from the use of corrosion free deck bridges, which have minimum maintenance, as has our innovative flexible concrete arch (patented 2004) which has been used for over 40 FlexiArch bridges (£15m in contracts) since 2008.
