ITM begins monitoring £75M A19 Silverlink Roundabout

Lagan Sisk JV have awarded ITM the monitoring works on the £75m lowering of the A19 beneath the existing A1058 Coast Road.

The junction, used by thousands of people every day is on the main route to and from the Tyne Tunnel. The job involves:

  • Building two bridges to carry the roundabout traffic across the lowered A19
  • Construction of a replacement bridge to support the A1058 Coast Road across the junction
  • New slip roads to provide access to the junction to and from the lowered A19
  • Two footbridges across the A1058 for pedestrians and cyclists.

The solution

ITM introduced a number of wireless monitoring techniques and as a result provided key value engineering benefits and improved health, safety and environmental metrics on the project through reducing the number of visits to site. The system being installed is based upon continuous remote structural health monitoring and utilises the following equipment:

  • Wireless linear potentiometers
  • Wireless tilt meters
  • Inclinometers
  • Piezometers
  • Manual surveying of targets.

All project-wide data is transferred to ITM’s own data visualisation package, Calyx OMS, which has received extensive praise across the construction industry for its ease of use and ability to manage multiple sites for  clients, notably Network Rail and The Coal Authority.

Monitoring on the project will continue for the next two and a half years, with ITM providing continual support throughout construction.


Looking ahead

ITM’s expertise in delivering large-scale remote monitoring systems for highways projects has resulted in a number of large contract wins, most noteworthy being the A50 Growth Corridor and A9-A85 Perth Junction Improvements. Rhiannon Walker, Business Development Manager at ITM highlighted that “..the open consultation we provide often enables key savings on large projects. We work closely with all clients to produce fit for purpose and effective monitoring schemes, which as a result reduce CO2 emissions and increase health and safety”.
