Ah Gary, what fun we had, you teaching me all about tunnels and me your willing pupil. You gave me a tour of Connaught Tunnel, explained how you’d taken the value from a few quid for a little bit of leak sealing injection, to £Millions for wholesale rebuilding of large sections. We took a trip to Puymorens Tunnel in the Pyrenees, and you told our host he was doing the sheet membrane all wrong. But your teaching worked, I became a “10-minute” tunnel expert and we only went and won SPT! It was brilliant working with you. You will be so sorely missed. Thanks for all the great memories and rest in peace old friend.
