In November 2020, the AGS launched their second photography competition, this time to source a suitable cover for the third edition of the UK Specification for Ground Investigation (Yellow Book) which is due to be published in early 2022.

A staggered 83 entries were submitted, each covering a range of topics across the geotechnical and geoenvironmental sector including site work, team work, landscape imagery and machinery shots.

AGS Chair, Sally Hudson, AGS Past-Chair, Julian Lovell and AGS Instrumentation and Monitoring Leader, Jonathan Gammon took on the challenging task to judge the images by scoring across four criteria;

  • Originality and Relevance
  • Composition
  • Colour, Lighting, Exposure and Focus
  • Overall Impression, Impact and Visual Appeal
  • Suitability for Yellow Book

Four images were shortlisted, and we’re pleased to announce that Mark Lindahl of Bridgeway Consulting was the overall winner of the competition and won a luxury Fortnum and Mason Hamper.

Our three runners up, who each won a bottle of Champagne are Bryan Laycock (Dunelm Geotechnical & Environmental Ltd), Jim Shields (BAM Ritchies) and Jon Ohashi (Soils Limited).

Image description: This was taken using a 360 camera. The image was taken in the following weeks after Rob Ainsworth sadly passed away, I was pretty close with that guy and was fortunate to be able to call him my friend, not just a brilliant boss! He always pushed for me to take photos not only for work but because he really liked them (I hope 😅) and he thought I had an eye for it.

The AGS would like to thank all those who took the time to enter the competition. The overall standard of entries was extremely high, and the judging panel found the task challenging in shortlisting the top four entries.
