A concert hall in Cardiff will remain closed until 2025 due to concerns over crumbling concrete.
Cardiff Council has said the roof of St David’s Hall will need to be completely replaced – work which could see the venue close for around 18 months.
Over the past few months, several public buildings across the UK have been targeted reinforced autoclaved aerated concrete (RAAC)including hospitals and schools.
The Health and Safety Executive (HSE) has said that the building material has now passed its intended lifespan and could collapse without warning.
Experts have been carrying out tests at St David’s Hall in recent weeks since RAAC panels were identified.
A number of the more than 900 panels in the roof are either classified as “red – critical” or “red – high risk”, according to a council report.
The engineers’ recommendation is that the site remains closed until temporary emergency measures are put in place or the entire roof is replaced.
The council says remedial measures will take “at least six months to install” and are likely to cost “several millions”.
However, the roof still had to be replaced regardless, and Cardiff Council’s cabinet are now recommending that it be repaired in one go.
Stars scheduled to perform at the venue over the coming months included Strictly Come Dancing featuring Janette Manrara and Aljaz Skorjanec, singer Sophie Ellis-Bextor, writer Grayson Perry and the bands Wet Wet Wet and Go West.
The council was in the process of entering into a lease agreement with AMG.
AMG remains committed to investing in St David’s Hall, according to the council, and it plans to reopen the venue “well before” the BBC Cardiff Singer of the World competition in the summer of 2025.
