CTS Engineering are uniquely placed to provide full tunnel lining investigation reports for brick and stone masonry lined tunnels. CTS offers full bore LiDAR scanning combined with down-core-hole videography and photogrammetry with LiDAR, to enable the assessment of the lining intrados and extrados. This is then summarised in a report of the asset lining which can then be used to more efficiently manage the tunnel in future and make engineering assessments regarding repairs. - Please contact one of our team for more information on this service
