Safety paramount
The total stations are functioning well with millimetre accuracy achieved. Data is recorded every 15
minutes, 24/7 providing valuable insights into the tunnel behaviour beyond what could have been
learned the traditional way. The system has proved to be a cost-effective, sophisticated high-end
solution, measuring data reliably and robustly, providing reassurance for site personnel that the
tunnel was reacting in a manner that was within safe engineering tolerances. It also provided
reassurance to Network Rail that the tunnel as a whole (eastern, central and western bores) was
structurally integral, and safe for the travelling public. By installing this innovative equipment, Amey
Consulting removed all boots on ballast during the construction phase of the project.
