An Oxford College has been forced to restrict access to “certain areas of its site” in response to finding reinforced autoclaved aerated concrete (RAAC) in its buildings.

More than 100 schools have been forced to close across the country due to the detection of RAAC.

St Catherine’s College has since revealed that it has closed off areas of its site as a “precautionary measure” due to “safety concerns”.

A statement published on their website said: “The College has recently engaged independent consultants to undertake appropriate risk assessments of the affected areas, which are principally located within the original Arne Jacobsen site.

“While these investigations are ongoing, the College has decided to restrict access to the affected areas temporarily, to enable investigations and assessments to take place, and mitigations to be put in place.”

The College said it would keep the restrictions “under continuous review with the expectation of lifting restrictions prior to the arrival of students in October”.
