For several years, the Centre for Smart Infrastructure and Construction (CSIC) at Cambridge University has been researching the potential for use of fibre optics within the civil engineering industry. More recently, Huesker have developed a manufacturing process to incorporate fibre optic cables into geogrid, forming a Sensorgrid, which has shown promising performance when tested under laboratory conditions.

This talk summarises the approach and findings of recent trials to investigate the performance of this technology at a larger scale, under site conditions, together with concepts for future applications. The trials were designed by Jacobs and constructed at the HS2 Phase 1, C1 site by ALIGN. Funding for the trial was provided by the HS2 Learning.
