The City Surveys Group surveying team have been chosen by Network Rail to work on an investigation project of Disley Tunnel.

Disley Tunnel [UK] was built by the Midland Railway in 1902 on its line between New Mills South Junction and Manchester Central, which was more direct than the congested and difficult lines through Stockport Tiviot Dale.

The team will be working out of hours on this busy line investigating the tunnel, compiling masonry core logsand inspections with an Endoscope.

The team will also be using a state-of-the-art C-ALS laser system that maps cavities and provides point clouds to feed into project models.

The team is looking forward to taking on this challenge and reviewing the results.

Richard Furlong, Chief Operating Officer commented…

‘We are excited about this new piece of kit in our surveying armoury, it will be instrumental in uncovering hidden areas once inaccessible to conventional surveying techniques. We are working with Network Rail on this project and plan to carry out many more investigations like this’.

More about the C-ALS laser system….

C-ALS (Cavity Auto-scanning Laser System) is a unique specialist underground laser cavity monitoring system that enables mapping of previously inaccessible parts of mines, safely and quickly.

C-ALS grants access to concealed cavities

C-ALS cavity monitoring system can be used in a wide range of applications, where an inaccessible void exists and accurate data is required to monitor excavations, assess risk or design solutions.

Once deployed, C-ALS gives more detailed, accurate data than alternative technologies, such as ground-penetrating radar, and is the only borehole-deployable laser solution on the market.

  •   Plan new projects: Assess risk, design solutions based on accurate underground data, add C-ALS data to your existing maps and devise new programmes of work.
  •  Transform productivity: With accurate maps of voids, you can design plans, which allow for efficient mining or construction projects.
  •  Improve safety: Map inaccessible underground areas to ensure operations keep employees safe.

Applications where C-ALS provides data when manned entry may not be possible:

  •         sub-surface voids and cavities
  •         undercrofts
  •         underground chambers and tanks
  •         duct surveys
  •         inaccessible roof spaces
  •         subsidence investigations
  •         collapsed mine workings
  •         culverts
  •         shafts and bunkers
  •         underground caverns
  •         industrial production facilities where access is limited or unsafe

C-ALS offers new capabilities, safety and cost benefits in a wide range of underground applications.
