Results of the pressure tests on Large Panel Systems following Ronan Point collapse

Dear Ministry of Housing, Communities and Local Government,

The report of the public inquiry into the collapse of the Ronan Point tower block was published in 1968. Following this, the Large Panel System buildings industry wanted to know a standard to build to. Circular 62/68 was published which said that every tower block should be able to withstand an explosive force of 5Psi (34kN/m2) It is understood that every block failed these tests at that time.

Under the Freedom of Information I would like to request:

1) All documents on this matter, relating to which tower blocks were tested, and what the results of those tests were for each block.

2) Information on any retesting that may or may not have been done following the publication of Circular 72/68 which said that if piped gas was removed, the explosive force could be reduced to 2.5psi (17kN/m2)

Yours faithfully,

Danielle Gregory
