RAAC (REINFORCED AUTOCLAVED AERATED CONCRETE) IN TfL BUILDINGS
Dear colleague,
Following receipt of information from your London Regional Transport Organiser, I wrote recently to TfL seeking assurances about the possible presence of RAAC (Reinforced Autoclaved Aerated Concrete) in any TfL buildings of infrastructure.
TfL has now published the following statement. This information is welcome and RMT will continue to be alert to the issue:
No known RAAC on our network and we're continuing to investigate.
We regularly inspect and review our entire estate and all of our assets to ensure they are safe for our colleagues and our customers.
Reinforced Autoclaved Aerated Concrete or RAAC (the building material that has led to recent public sector building closures) has not been specifically flagged in our inspections and it hasn't been registered in our database.
We can't completely rule out its use because our records vary, but the likelihood is low.
RAAC is not a material typically used in our infrastructure and, unlike other parts of the public sector, we bring together technical and operational specialists to evaluate the condition of our assets using multiple sources of data and information. We always take action when necessary to ensure our assets are safe.
We continue to make assessments that will identify and assess any potential risk from RAAC. We will take steps to mitigate the issues where it's needed. We're also working to identify how we identify RAAC as part of visual surveys.
Our assets managed by TTLP (our commercial property company) tend to be larger and older, so we're carrying out a programme that is assessing the use of RAAC in these locations.
Please continue to report any faults or concerns you have with any of our assets through our regular fault reporting processes.
Yours sincerely,
Michael Lynch
General Secretary
