No lessons learned following Ronan Point
Large Panel System (LPS) built tower blocks was the cheap and expedient response to post war housing need. Yet the system was fatally flawed and now widely discredited. Yet it seems many seriously unsafe buildings remain. It is 50 years since Ronan Point collapsed and in the wake of the disasters at Lakanal House and Grenfell Tower Danielle Gregory from Ledbury Estate calls for urgent action. She says " It was thought that the Ledbury Estate was a one-off, one estate which had somehow slipped through the net and not been strengthened." Through her initial research Danielle has identified that there are potentially at risk blocks in Hackney, Haringey, Hammersmith & Fulham, Leicester, Lewisham, Rugby and more.
She calls for Government action now " 50 years ago, the Government of the day issued circulars and effectively left building owners to get on with it. Who was checking that the strengthening work was ever actually carried out on these buildings? Apparently nobody. Who was checking that if strengthening was done, that it actually worked and was effective in making these buildings resistant to the vulnerabilities of progressive collapse? Apparently nobody.
If the Government do not step in now and offer support, funding and a dedicated body to address the issues in Large Panel System blocks, then we are at risk of seeing another Ronan Point."
This is an example of the importance of listening to the voice of tenants and residents who know their blocks. Read the full article with images at: wwww.ledburyestate.com/Campaign blog. Or here is the plain text version.
No Lessons Learned Following Ronan Point
By Danielle Gregory,
Wednesday 16th May 2018 marks the 50th anniversary of the partial collapse of Ronan Point, a 22 storey tower block in Newham, East London. On 16th May 1968, tenant Ivy Hodge lit a match to light her gas stove, resulting in an explosion which brought down one side of the building, killing four people and injuring many more. Ivy Hodge herself survived the blast.
Ronan Point was a Large Panel System tower block, built cheaply and quickly in response to the urgent need for housing in the UK following WWII. Taylor Woodrow Anglian were a newly formed company who began building these blocks in the late 1960's. They had purchased a licence for a method of construction from Denmark called 'Larsen Nielsen' - this method was originally designed to be built only up to 6 storeys high. Taylor Woodrow Anglian built blocks using this method nearly four times as high as recommended. The large concrete panels were bolted together onsite, using unskilled labour. They have no supporting frame, and only their own weight and gravity holding the structure together.
Following the collapse of Ronan Point, the UK Government quickly issued circulars (62/68 and 71/68). These documents said that if these types of Large Panel System tower blocks could not withstand certain blast pressures, then gas supplies needed to be removed, and the buildings must undergo structural strengthening.
Ledbury Estate Southwark
Fast forward nearly 50 years to the discovery at the Ledbury Estate, that four 13-storey Taylor Woodrow Anglian tower blocks had never undergone this structural strengthening, they were also fitted with a gas supply. An explosion at any time over the past 50 years could have led to collapse. Upon learning this, Southwark Council turned off the gas supply and instructed ARUP engineers to design a strengthening solution for the Ledbury towers, which would bring them up to meet the building regulations. In the meantime, the towers are in the process of being decanted for either major works, or demolition ahead of a decision by Southwark Council on the future of the four towers in September.
