  • Client: Multiple Organisations
  • Location: National
  • Sector: Education, Government
  • Services: Building Surveying, Funding/Bid Writing, Structural & Civil Engineering


Following a DfE alert, all schools across the UK were required to identify and mitigate against a potentially dangerous form of concrete, RAAC. Barker mobilised and completed over 600 surveys and supported schools and trusts in dealing with RAAC where found.

Barker also worked with leading sector bodies Confederation of School Trusts (CST) Association of School and College Leaders (ASCL), Institute of School Business Leadership (ISBL) and The Trust Network (TTN) to provide advice on guidance and best practice through briefing notes and webinars.

The Brief

With our multi-disciplinary team of surveyors, structural engineers and education sector specialists, Barker were ideally placed to rapidly deploy staff to deal with the urgent survey requirements and advise schools on their options where RAAC had been identified.

The Challenge

The government’s announcement in August 2023 that required all school buildings with RAAC to close, marked a significant change in policy. Being close to the start of a new school year placed huge pressure on schools, responsible bodies and the sector. It was critical to ensure the safety of buildings whilst minimising disruption to teaching and impact on staff and students.

The Outcome

Barker supported over 600 schools and trusts across the country with a range of services:

  1. Surveying buildings to identify RAAC
  2. Arranging emergency facilities and temporary accommodation
  3. Designing and implementing mitigation measures
  4. Arranging removal and replacement of defective elements.

Barker continue to work with clients and the wider sector to provide longer term solutions including removal of RAAC where necessary.
