On the 15th and 16th of November 2017, the team had the pleasure of hosting Dr Richard Yelf in Singapore. He had kindly shared with us his knowledge on using Ground-penetrating radar (GPR), an equipment that uses radar pulses to image the subsurface of walls and floors, often making the invisible visible. This is a non-destructive testing method adopted to detect subsurface objects, voids and cracks, etc. during site inspections and investigation for various projects.
Richard provided many subtle but critical pointers of the technique. He passionately shared his experience and discussed many cases during the site training involving various modern and old architecture.
Our team members have shared that what they learnt in these two days spent in the office and at site with Mr Richard were very helpful as the knowledge learnt could be applied to the works they undertake.
