Edinburgh Council has said that early indications show that structural faults have been found at all of the 17 schools currently closed.
Almost 6,000 pupils in the city have been affected and the Council is making alternative arrangements for education provision while repairs are carried out on the schools built through the PPP1 scheme.
Council leader Andrew Burns said: “Yesterday evening the Council received early indications that suggest evidence of faults across all 17 affected schools to a varying extent. At the moment it is too early to say what the impact will be as full survey results from Edinburgh Schools Partnership have not been yet been received. Some faults may be easy to fix and may not present a major problem while others could be longer term.
“We will provide parents with further information on the impact of individual school surveys once the full reports are received and assessed.
“What is certain is that we won’t take risks with the safety of our schools children and schools won’t reopen until Edinburgh Schools Partnership can assure us of their safety. As part of the contract, Edinburgh Schools Partnership own, maintain and assure the safety of the affected buildings.”
Structural surveys are continuing this week and Galliford Try is already completing repairs to the four schools for which it has contractual responsibility.
Safety concerns were originally raised in March after a wall collapsed in high winds at Oxgangs Primary School.
City of Edinburgh Council said engineers working on remedial works at the school had found an absence of “header ties”, the sliding links that connect the inner block wall to the structural steel frame.
