A second public building has been partially closed in Hampshire after it was found to contain prone-to-collapse reinforced autoclaved aerated concrete (RAAC).

Hampshire County Council confirmed earlier this week that temporary work had been taken to make a building at Cranbourne College secondary school in Basingstoke safe.

And on Thursday, the council also confirmed RAAC has been found at South Ham Community Library, also in Basingstoke.

A spokesperson for Hampshire County Council, said: “In relation to public buildings maintained by Hampshire County Council, we can confirm two known cases of RAAC.

“Cranbourne College in Basingstoke is the only school site under our management where RAAC has been identified. Temporary work has already been undertaken to one section of the building to make sure it is safe, and another area has been taken out of use since the beginning of the year. The school has reopened for the new academic year as normal. 

“Following a detailed structural survey carried out on Wednesday, September 6, RAAC has been confirmed within an area of South Ham Community Library in Basingstoke, in an area of the building that is owned by Hampshire County Council.

"This area is used by a community group, and we have notified them of the outcome of this survey. As a precautionary measure we have instructed that the impacted areas are closed immediately and remain closed until appropriate mitigation measures have been implemented.

"Other areas of the building are owned by Basingstoke and Deane Borough Council, and we have notified them of the outcome of our investigation.

“The county council is responsible for a large estate, and we have a comprehensive inspection programme in place for all our buildings, including structural surveys by qualified engineers. 

"Through these, RAAC has not been identified elsewhere, however we continue to monitor the position with RAAC across our estate and would investigate, and take appropriate action, should issues be identified.”

The government published an official list of 147 schools in England it says have the crumbling RAAC concrete on Wednesday.

Four of these schools are teaching all pupils online as a result of RAAC, according to the government.

The DfE list only includes schools in which RAAC had been found by surveyors appointed by the DfE– so excludes schools that have done their own surveys or those that confirmed they had used the concrete more recently.

According to the list, 19 schools in England, with around 9,731 pupils, have delayed the start of the new school year.

Another four schools, with 2,960 pupils, are undergoing fully remote learning and 22,339 pupils across 20 schools are receiving a mix of face-to-face and remote learning.
