Kevin Stewart, from the Ellon area, was preparing a room in a hotel for painting on Tuesday September 4 when he sustained “serious head injuries” at the new £333 million development.

Emergency services were called to the scene and he was placed in an induced coma at Aberdeen Royal Infirmary.

The 51-year-old later died in hospital.

An investigation into the incident is underway.

A spokesperson for Robertson Group, which is constructing the complex on behalf of Aberdeen City Council and its development partner Henry Boot Developments, said: “We are devastated by the news that Kevin Stewart, a contractor who was working at the new AECC site, has passed away over the weekend. Our thoughts are with his family, friends and colleagues at this very difficult time.

“The Health and Safety of all our employees and contractors remains our top priority, and we are committed to supporting the ongoing Police and Health and Safety Executive investigation into the incident.

“Employees on the AECC site who feel affected by this tragic incident have been offered the use of a free counselling service, which is open to all employees.”

Detective Inspector Allen Shaw said: “Our enquiries are continuing, with officers working alongside the Health and Safety Executive.

“Our thoughts are with the family of this man at this very sad time.”

A HSE spokeswoman added: “HSE is aware of the incident and is making enquiries.”
