IQ North Wales - QNJAC Managing Significant Change

Technical event
26 March 2024, 18:00
Colwyn Bay Rugby Glub, Brookfield Dr, Rhos on Sea, Colwyn Bay, LL28 4SW


The North Wales branch welcome members back with a presentation from Thomas Clifford of GEARS and member of QNJAC Geotechnical Group. This presentation will look at the requirements set out in Regulation 34 - Operator’s duties in relation to excavations and tips which are a Significant Hazard.

Each Significant Hazard within a quarry must have a valid Geotechnical Assessment but the operators’ duties don’t stop there as the Geotechnical Assessment is only as robust as the process to manage Significant Change. So, what is Significant Change? Who's responsibility is it? What makes a change a Significant Change? Why should you care about Significant Change… All these questions and more will be answered.

Thomas Clifford is a Chartered Engineer and Geologist who has spent his professional career studying the relationship between geology, quarry design, rock mechanics and blast design. Thomas is well known in the extractive industry having started his career as a Geologist then Geotechnical Specialist at Aggregate Industries. Following his time at Aggregate Industries he joined one of the largest engineering consultancies in the world, Atkins, where he eventually headed up the UK Extractive Industries team and became involved in Expert Witness Services.

In 2021 he joined Ground Engineering Applied Research Services (GEARS) as a Technical Director and has since been developing the Mine to Mill system, which combines the latest advances in blast design, geotechnical engineering, machine learning and full life cycle cost modelling for the quarrying industry.

The event starts at 6pm for a 6.30pm and a buffet will be provided.
