Rufus Foster

Technical Director, GScan

Rufus is a Chartered Structural Engineer, experienced in the inspection, testing, structural assessment, design, and strengthening of bridges and heavy civil infrastructure.

He recently joined GScan as UK Technical Director where he is leading the adoption of muon tomography in the bridges and civil infrastructure sector. This ground-breaking non-destructive testing technology enables engineers to visualise the previously unseen by generating high-resolution 3D images of hidden elements buried deep within structures.

Muon Tomography in Practice: Revealing the Hidden Details of Llanrhystud Bridge

11:50 - 12:10

  • Llanrhystud Bridge on the A487 faces uncertainty due to missing drawings and undocumented post-tensioning and reinforcement.

  • Conventional investigations (GPR, coring) failed to confirm these details, limiting structural assessment.

  • Muon tomography, proven in Structures Moonshot, was deployed for the first time on a live UK bridge to deliver deep, high-resolution internal imaging.

  • The presentation covers the on-site deployment, key challenges, and insights from the measurements.

  • It also offers a customer perspective, outlining lessons learned and future applications for ageing, undocumented assets.
