A combined LBA / Costain team are presenting a tunnelling success story at this year’s Instrumentation and Monitoring Conference at Inmarsat 29 – 30th March.

The 5.5m external diameter Mixshield for the Shieldhall Strategic Sewer. The tunnel was driven beneath a busy railway line in Glasgow with 3.5m of cover between the tunnel and the railway. The crossing was undertaken during a weekend possession, minimal effect was incurred on the overlying railway and the line was re-opened in time for traffic on Monday morning.

LBA’s Dave Terry, the Contractor’s Engineering Manager for the tunnelling works, will present alongside Costain’s Neil Grosset, the Project Director.
