Carl Butler
After his PhD, Carl became a post-doctoral research associate in the Chemical Engineering Department at the University of Cambridge. He studied the chemistry involved with the production of high purity silica and also completed research work for industrial clients using fluidised bed reactors. In 1997, Carl moved to the Process Safety Section of the Health and Safety Laboratory (HSL), an agency of the Health and Safety Executive. His work there, initially as a Higher Scientific Officer, involved the assessments of hazards associated with industrial chemical reaction processes, including runaway chemical reactions, BLEVEs and LPG vapour cloud fires, for which he was a partner in a European Joint Industry Project. Later, as Senior Scientific Officer, he led a research team investigating hazards associated with a wide range of processes, including high pressure water-jetting, fire-engulfment valves, LPG-storage and pool fires. Carl was also involved in large-scale testing to assess the hazards presented by the use of hydrogen as a fuel. His work at HSL also included the investigation of a number of incidents and he was an incident officer for the Process Safety Section. He also produced industry guidance on prevention of over-pressurisation of storage silos. Carl joined Hawkins in 2004 and […]

Patrick Barbour
Having obtained a Masters degree in Mechanical Engineering, Patrick spent two years designing sub-sea wellhead equipment for the North Sea oil industry. He then returned to Leeds University to carry out research into the wear of polymers used in artificial hip joints. Having gained a PhD, he continued his research and lectured Mechanical Engineering at Leeds University. Patrick joined Dr J H Burgoyne and Partners LLP in 2000 to investigate incidents involving personal injury and mechanical failure for insurers and solicitors. During this time the findings of his investigations were used in numerous court cases, both civil and criminal, and he attended arbitrations and mediations to present expert evidence. In 2008 Patrick joined Hawkins in our Bristol office where he continues to use his expertise to investigate incidents of personal injury and mechanical failure. Patrick’s cases have involved the safety of systems of work and the failure of engineering components in commercial and domestic installations. These cases can require the analysis of stress and failure modes of a variety of materials, loads generated by static and moving bodies, thermodynamics and fluid flow as well as the safety of systems of work and the safety of interlocking systems intended to prevent […]
Robert Edwards
After completing a Post Doctoral Research Fellowship, Robert joined Liverpool John Moores University as a Lecturer and then Senior Lecturer in Environmental Chemistry. Here he developed a successful research programme in environmental chemistry and environmental analysis, publishing numerous papers in scientific journals and books and presenting research work at many national and international conferences. Robert has lectured extensively on analytical, environmental and corrosion chemistry. He was the course leader for the University’s MSc Analytical Chemistry course and was an assessor for the Higher Education Funding Council (Wales). Robert also gave annual lecture courses and workshops in Universities in Thailand, where he was a visiting lecturer. Since joining Hawkins in 2001, Robert has specialised in post-fire, post-flood and post-chemical spill contamination investigations throughout the world. This work involves determining the effects of contaminants on buildings, production equipment, complex computer systems and products, including food stuffs, and providing advice on the long term effects of the contaminants and best remediation techniques for recovery. During his time at Hawkins, Robert successfully completed the BOHS course for surveying buildings for asbestos and has since carried out asbestos contamination surveys following various incidents in the UK and Europe. Robert has also conducted many forensic fire […]
Andrew Prickett
As part of his first degree Andrew worked for Alusuisse, Switzerland analysing production methods of lithographic alloys and for the Defence Evaluation and Research Agency on new materials for aerospace applications. His career in failure investigation began while carrying out his PhD, which was an investigation to determine the failure characteristics of fibre reinforced composite materials using fracture mechanics and surface analytical techniques, that was sponsored by BAE Systems. After completing his PhD, Andrew continued his interest in failure investigation by undertaking a post-graduate research project for Thames Water on the failure modes of cast iron trunk mains systems.In 2001 Andrew joined Hawkins, specialising in the investigation of materials failures, escapes of water, fires and explosions. He has investigated a wide range of failures in plastic, ceramic, metal and composite materials. He also uses his engineering knowledge and experience of the processes required for a forensic investigation to determine the causes of fires in residential, commercial and industrial premises.Andrew is experienced in the legal process; he is frequently appointed as a Single Joint Expert and has given evidence in the capacity of an expert witness in Magistrates’ and Crown Courts. In 2022, Andrew was promoted to Managing Director and is […]
Jake Irwin
After completing a PhD at the University of Sydney, Jake joined the National Measurement Institute of Australia producing certified analytical reference materials. He then took a Post Doctoral Research Fellowship at the University of Warwick, performing chemical synthesis and analysis for a wide variety of projects. In 2006 Jake joined the Forensic Science Service as a Researcher and then R&D Science Manager in the physical sciences. He led progress in the analytical sciences (in particular the toxicology & illicit drug testing fields) and drove the development and implementation of quality assurance standards at a European level. Jake also worked on many collaborative projects with universities and other research organisations. Since joining Hawkins in 2012 as a fire investigator, Jake has investigated many fire scenes from small domestic losses to large commercial losses. More recently Jake has also investigated chemical, post-fire and post-flood contamination events. Jake is currently a Principal Associate and Regional Manager of our Birmingham office.
Andy Bryce
Andrew’s career in forensic engineering began while carrying out an undergraduate placement at the Royal Aircraft Establishment, analysing the cause of aircraft component failures for the Air Accident Investigation Branch. Following his Masters Degree he joined Rolls Royce plc, Military Engine Division in 1988 where he was trained in the forensic investigation of engine failures for both in-service and development engines. Other areas of responsibility included carrying out in-service turbine component condition assessments and writing quality standards. Andrew resigned from Rolls Royce at Senior Scientist grade and joined Hawkins in 1991. Since joining Hawkins, Andrew has carried out over 1700 forensic investigations involving engineering, fire and explosion incidents both in the United Kingdom and overseas. These cases have covered a great range, from small domestic incidents to multi-million pound losses in shops, warehouses, factories, power stations (gas turbines & compressors), aerospace and marine. Andrew is experienced in the legal process and has given evidence in the capacity of an expert witness in Magistrates’ Courts, County Courts, High Courts, Crown Courts, Coroner’s Courts, mediations and arbitrations on numerous occasions. He is listed as an expert in the Expert Witness Directory. Andrew is currently a Director of Hawkins and based in the […]

Ice, Ice Baby
Winter sees a seasonal increase in escapes of water in both domestic and commercial properties due to the freezing of water pipes. The UK Water Regulations state that “All cold water fittings located within the building, but outside the thermal envelope, or those outside the building must be protected against damage by freezing”.
