An inquest into the deaths of four men from Stanton and Rickinghall is due to open at Sprowston Manor Hotel, in Norwich, on Monday.
Brothers Daniel and Tom Hazelton, aged 30 and 26, and friends Peter Johnson, 41, and Adam Taylor, 28, were killed in an industrial accident on Claxton Engineering’s site, Great Yarmouth, in January 2011.
Hannah Clarke, a personal injury specialist at Ashton KCJ solicitors, will be representing the men’s families.
She said: “The incident has already been the subject of a joint investigation between the Norfolk Constabulary and the Health & Safety Executive.
“The project on which the men were working was a pressure test facility for the oil and gas industry. Although taking place on the Claxton Engineering site, the project was being run by Encompass Project Management Limited who had sub-contracted work to Hazegood Construction Limited.
“The structure on which they were working was designed by URS Infrastructure and Environment UK Limited. One of those killed was a director of Hazegood Construction Limited and the other men who died were employed by Hazegood.”
She added: “From the families’ perspective there are many questions which remain unanswered and we will be attending the inquest on their behalf in order to provide any assistance we can to Coroner Jacqueline Lake in ascertaining the exact circumstances that led to their tragic deaths.”
