Contractors and materials should have been organised ready to arrive on site when schools finished in July
The timeline is:
2018: Primary school ceiling collapses in Kent. If kids had been in the building at the time (it was the weekend), there could have been fatalities. It is clear that RAAC is actively dangerous and poses a risk to life and limb.

Dec 2022: The risk of school building collapse is upgraded from critical to very likely
March 2023: Schools are sent a survey asking if they have an RAAC in their buildings
June 2023: The DfE sets up a call centre to phone schools asking why they haven't filled in the survey. Answer "Do I have RAAC? No idea"
Last of week August 2023: Some schools who do know they have RAAC are contacted by the government and informed that they have to close immediately because their schools are too dangerous to open.
