Grenfell Tower inquiry: combustible insulation product
The inquiry heard that safe mineral wool product was ruled out because ‘aspirational’ efficiency target would not have been hit.
A Mechanical and Electrical systems consultant (M&E Engineer) on the Grenfell Tower refurbishment project recommended the use of combustible insulation on the outside of the block as a way to meet an “aspirational” thermal efficiency target.

Grenfell Tower inquiry: combustible insulation
Rydon’s refurbishment director on the Grenfell Tower refurbishment, Stephen Blake, has admitted to being “haunted” by the lack of scrutiny of the ill-fated project’s cladding and window designs.
Stephen Blake said that in hindsight key elements of the tower block’s refurbishment had been presumed to be correct when they were not.
He also advised that he believed it had been original project architect Studio E’s responsibility to arrange – and pay for – any specialist fire safety advice required, even after Rydon was appointed main contractor on the project and Studio E novated to it.
Fire specialist Exova was hired by the client (Kensington & Chelsea Tenant Management Organisation) and produced an outline fire safety strategy for the refurbishment in 2013.
However the firm was not novated once Rydon was appointed in 2014.

Grenfell Tower inquiry: combustible foam boards
The refurbishment specification was to pack the gaps around the windows with non-combustible Rockwool insulation fibre, but Mark Dixon’s company, SD Plastering, instead used combustible foam boards apparently.
The Rydon manager in charge of the project, Simon Lawrence told the inquiry that he didn’t read a bill of works that showed SD Plastering planned to use Celotex panels, at odds with the safer specification. This was in breach of building regulations. The inquiry has already concluded that the foam insulation in the window surrounds “contributed to the rate and extent of vertical flame spread”.
When Simon Lawrence inspected the works in 2015, there were missing finishes and gaps. Emails at the time showed he thought it was “a disaster”.
Simon Lawrence received an email from the Tenant Management Organisation (TMO) – which ran the tower in North Kensington – seeking clarity on whether the new cladding would resist a fire.
There is no evidence that he or anyone from Rydon replied to that email.

Grenfell Tower residents branded as “rebels”
The builder in the Grenfell Tower refurbishment branded residents who questioned the quality of works as “rebels” and complained that they were “persistent and aggressive”.
Evidence has exposed the toxic atmosphere between contractors and occupants of the west London council block. The inquiry also heard there were allegations of harassment and threats by employees of Rydon and of the K&C tenant management organisation (TMO).
Rydon manager Simon Lawrence admitted in an internal email that the site was “poorly performing”. He also apparently noted they were using “cheap incompetent sub-contractors”.
Neil Reed, head of project delivery at the landlord’s agent, complained: “I have never worked with a contractor operating with this level of nonchalance.”

Grenfell Tower inquiry: Lead fire consultant ‘ignored’ cladding email
The lead fire safety consultant of the Grenfell Tower refurbishment ignored documents outlining proposed cladding and insulation materials.
Terry Ashton, of fire engineering company Exova, said he did not read an email from Studio E architects detailing a planned cladding system because he was not the “primary recipient”.
He also failed to read the architect’s progress report.
The inquiry has concluded that cladding fuelled the 2017 fire in west London.
Grenfell Tower cladding – for top and bottom of the building, the principal cladding appears to be noted as ‘3’ (medium grey, ACM) and ‘5’ (white, rainscreen) in the top left key, ie ACM panels:

The email from architects Studio E on 23 October 2012 included attachments containing details and drawings of a planned cladding system.
Asked why, he told the hearing that people are often copied into emails on big projects in “a sort of scattergun approach”.
He also did not read the architect’s progress report which he was sent on 31 October 2012, and failed to mention plans to cover the tower block in cladding in his first fire safety report published on the same day.
He had no formal training as a fire engineer, despite working as a fire consultant for 25 years.

Grenfell Tower inquiry: Fire ‘inextricably linked with race’
The inquiry returned this week after a four-month break due to coronavirus.
Leslie Thomas, who is representing survivors and bereaved families, said the 2017 fire was “inextricably linked with race”.
There were 72 victims.
Legal submissions made to the inquiry explain there were 4 visitors to the tower among the dead and also a stillborn baby and then adds: “Of the remaining 67, 57 were from BAME (black, Asian and other ethnic minority) communities.
On Monday, a senior fire safety engineer advised the inquiry he did not think putting cladding on Grenfell Tower would pose any “issues” for safety.

Grenfell Tower Refurb Architects Attacked
Studio E Architects is among a number of firms accused of attempting to derail the Grenfell Tower Inquiry with a wall of ‘corporate silence’ after it failed to provide an opening statement to the hearing, reports the Architects’ Journal.
Many of the 19 ‘core participant’ firms involved in the £10m refit of the tower on the Lancaster West estate have refused to comment on their work until they have full disclosure of documents, the inquiry heard yesterday.
They face a barrage of criticism from lawyers representing survivors and the bereaved, for failing to set out their position, especially on the key question of compliance.
In a blistering attack on the companies, Stephanie Barwise QC said: ‘these corporates have no desire to assist this inquiry, even though their participation could save lives in the immediate future.’
e-architect approached Studio E Architects for comment shortly after the fire but never received a reply.

Grenfell Tower Fire Interim Report
Dame Judith Hackitt’s Review of the Building Regulations and Fire Safety
Association for Project Safety (APS) fully supports the interim report of Dame Judith Hackitt’s Review of the Building Regulations and welcomes the next phase.
In response to the interim findings of Dame Judith Hackitt’s review of fire and building regulations, Bobby Chakravarthy, President of the Association for Project Safety said:
“The Association for Project Safety agrees with Dame Judith Hackitt that safer buildings start with good design and ensuring corners are not cut and clear regulations are established and consistently applied. But, for this we have to untangle the mare’s nest of complex and sometimes competing regulations, critically ensuring everyone involved in the design and risk management process is equipped with the relevant and up to date skills and education to build safe.”
Interim findings of Grenfell Review
A review of building regulations ordered after the Grenfell Tower fire has found the system is “not fit for purpose” and open to abuse by those trying to save money, reports The Guardian today.
Dame Judith Hackitt’s interim report into building safety called for an overhaul of the construction industry to put safety above cutting costs.
In a foreword, Hackitt said she was shocked by some of the practices she had uncovered. “The mindset of doing things as cheaply as possible and passing on responsibility for problems and shortcomings of others must stop,” she wrote.
Her report highlights concerns about increased privatisation of the building inspection regime leading to safety being compromised and a reduction in expertise within local authorities.

RIBA responds to Hackitt Interim Report
RIBA responds to Interim Report of the Independent Review of Building Regulations and Fire Safety
The Royal Institute of British Architects (RIBA) has welcomed the publication of Dame Judith Hackitt’s Interim Report but has highlighted the need to go much further, specifically in terms of making real and meaningful change to the core building regulations guidance covering fire safety, which is needed as a matter of great urgency.
Immediate Past President of RIBA and Chair of the RIBA’s Expert Advisory Group on Fire Safety, Jane Duncan says:
“I’m pleased that Dame Judith Hackitt recognises the current regulatory system is not fit for purpose and that there is a lack clarity of roles and responsibilities in the construction industry. The RIBA’s Expert Advisory Group on Fire Safety strongly recommends that the final review should require a named person or organisation to hold prime responsibility for the oversight of fire safety in the design and construction of any building project. It is disappointing that the interim review has not called for an immediate prohibition on the use any combustible materials in the external wall construction of high-rise buildings. This means we continue with this grey-area in regards to fire-safety”
The RIBA welcome that the report seeks:
• Better definiteion and allocation of roles and responsibilities within the building and fire regulatory system, with defined duty holders. The RIBA hopes that the final report will require a named person or organisation with prime responsibility for oversight of fire-safe design and construction on any building project
• Increased independent oversight of the quality of construction work
• Stronger compliance and enforcement of building control
• Raised levels of competence and accreditation of those involved in design, construction and maintenance of higher risk buildings
It is also good to see a recognition by Dame Judith of the importance of the ‘golden thread’ of original design intent, the integrity of which must be maintained in any building project or subsequent refurbishment – in order to avoid fragmentation of design responsibility with risks poorer quality outcomes.
However, it is disappointing that whilst the report recognises the complexity and lack of clarity in the current building regulations guidance, it shies away from introducing immediate and effective changes to the current fire safety guidance, Approved Document B.
The RIBA would like to see:
• An immediate prohibition on the use any combustible materials in the external wall construction of high-rise buildings
• A greater role for sprinklers as an active life safety measure in residential buildings
• Requirements for at least two staircases, offering alternative means of escape in high-rise residential buildings

Kensington Stories Documentary Film
Ladbroke Grove Youth Charity Focus on four local buildings
Kensal House, Trellick Tower, Stanley Gardens and Lancaster West
Young people look at West London’s skyline through the lens of a documentary
SPID Theatre Company, an award winning youth charity based in Ladbroke Grove, is looking at West London’s skyline afresh following the Grenfell Tower fire.
The result is Kensington Stories, a new documentary film made as part of SPID’s Living History project. SPID Theatre Company has achieved National Press on multiple occasions for their work, specialising in engaging hard-to-reach audiences with heritage, the arts and with each other. The project will build on their previous Living History Projects: Kensal Voices, Kensal Voices Reloaded, In Transit, Trellick Tales and Reimagining Goldfinger.
The film focuses on community, the management of buildings and the event of the Grenfell Tower fire that happened earlier this year. From recording oral history interviews, led by Rib Davis, SPID has worked with filmmaker Susanna Fasciolo and producer Ioana Constantinescu to create a fifteen minute film about four local buildings: Kensal House, Trellick Tower, Stanley Gardens and Lancaster West, where Grenfell Tower is situated. Each of these buildings is listed and protected, except Lancaster West.
Despite not being listed, Grenfell is extremely significant to the work that SPID is creating, work that champions local voices and shared histories. SPID itself is based in one of West London’s very own listed buildings, adding relevance to this year’s project. The oral history testimonies given by residents who live within each of these estates compose the soundtrack for the film; their own stories and opinions colouring the background to this documentary.
The entire project has been influenced by local young people aged 13-25, who participate in weekly workshops researching the history and architecture of the borough. This project is a combination of historical and architectural knowledge, enriched by personal stories about an area of London with extremely diverse buildings.
The Kensington Stories film will premiere on 9th December at 3pm at Kensal House, followed by a Q and A with the young people and makers of the film, and accompanied by food from the Goldfinger Factory, a café near Trellick Tower.
“I just love living in this Borough…when the rain clouds come in and you can see the shadows over the various parts of London, it all makes sense” – Lou D’Arcy, Trellick Tower Resident
“Based in West London’s Kensal House estate, SPID shares a landlord with Grenfell. This project champions local estate voices and makes the case for listening to and empowering them” – Helena Thompson, Artistic Director

Grenfell fire Criminal Charges
Criminal charges carrying lengthy prison sentences not ruled out by DPP
The UK Director of Public Prosecutions (DPP) has not ruled out possible criminal charges carrying lengthy prison sentences against individuals over the Grenfell Tower fire, report The Guardian.
In her first public comments since the disaster, Alison Saunders said investigations were at a very early stage. All options remained open, but it could take months before charging decisions can be made, she said.
Gross negligence manslaughter is among offences prosecutors could consider if police find sufficient evidence. The offence carries a maximum sentence of life in prison for those found to have high levels of culpability.
Alison Saunders, in an interview with the London Evening Standard, said: “All of us want to see justice done … It is one of those tragedies where everybody will want to do as much as they possibly can in order to help both those who continue to be residents and those who died in the fire.
The DPP’s comments follow the publication of a Scotland Yard letter which said there were reasonable grounds to suspect that corporate manslaughter offences had been committed by Kensington and Chelsea council, and the Kensington and Chelsea Tenant Management Organisation, the latter of which ran Grenfell tower.

Grenfell Tower Fire Update
Police Investigation Update
Police investigating the Grenfell Tower fire say they have “reasonable grounds” to suspect that corporate manslaughter offences may have been committed, report the BBC.
It means senior executives from the council and the tenant management organisation that ran the block are likely to be interviewed under caution.
A letter from the Met Police to residents said officers had “seized a huge amount of material”.
Organisations guilty of the offence of corporate manslaughter are liable to an “unlimited fine”.
Individuals cannot be charged with corporate manslaughter, an offence which is intended to work “in conjunction” with other forms of accountability.
The Royal Borough of Kensington and Chelsea and the Kensington and Chelsea Tenancy Management Organisation have been notified that there are reasonable grounds to suspect that each organisation may have committed the offence of corporate manslaughter.
However Labour MP for Tottenham, David Lammy, said the punishment for corporate manslaughter, a fine, would not represent justice: “Gross negligence manslaughter carries a punishment of prison time, and I hope that the police and the CPS are considering charges of manslaughter caused by gross negligence”.
More positively the Justice 4 Grenfell campaign group, said the development would help increase levels of trust between the police and the community.

Police confirm 255 residents escaped blaze
Investigators say 350 people lived in the west London block but 14 were not there when the building went up in flames, report The Independent.
Police said they do not expect the death toll to rise much further.
Detectives also revealed the tower was made up of predominantly one and two bedroom flats, which would account for the lower than expected occupancy.
Previous estimates put between 400 and 600 people living inside the tower.

Grenfell Tower Publc Inquiry
Grenfell Tower inquiry public hearings in September
The Grenfell Tower fire inquiry hopes to hold its first public hearings into the cause of the disaster in September as it prepares to seize council planning archives, report The Guardian.
Sir Martin Moore-Bick, the chairman, is expected to hold further meetings with bereaved relatives, local residents, survivors and interested organisations next week in order to agree terms of reference.
Until those terms are approved by the prime minister, Theresa May, and lodged with parliament, investigators cannot begin taking evidence.

Grenfell Tower Planning Conditions
Samples of Grenfell Tower Cladding
An interesting article by Ian Abley, focusing on two of the planning conditions, 3 & 4, and how they were processed by the architects, but also on a critical change to the window position half a year after planning:
Grenfell Tower planning application PP/12/04097 was determined by delegated powers.
Samples of the ACM panels were requested and should be in the council’s stores. Apparently the responses to the Conditions note the panel outer surface but crucially do not identify the core material.
The most recent of two references to the ACM panel specification is apparently the Studio E “Material Palette” dated 25 September 2014 and uploaded as Drawing-Approved-1332326 prescribed the ACM face as “Smoke Silver Metallic Duragloss 5000”
Our brief research shows this is an Arconic product: Duragloss 5000
The link to ‘DURAGLOSS® 5000 Technical Data’ goes to a ‘Content Not Found’ page.
Design Change Made in January 2015
Then there was a Non-Material Amendment made to approval PP/12/04097 after CON/14/04024. On 2 January 2015 proposed changes to the design by Studio E and planning consultants IBI Group were accepted by RBKC planners as NMA/14/08597. The design changes appear very material in that they re-position the windows, out from the existing concrete into the (rainscreen) cladding zone.
Ian notes that the planned separation of the window from the concrete meant that interfaces – “window, head and cill extrusions, foams, perimeter filler insulation, water, air and vapour barrier, and lining boards” – became technically critical for fire safety.
The several materials and products within the interface gap became the only construction stopping a fire inside a flat from reaching the cavity and cladding.
In other words, the late change to the window position, moving it out from the solid concrete structure, meant it was weak due to the ‘filled gaps’ around the sides where fire could break through.
Ian goes on to warn, “Planners should know something about the existence of such fire risks. But if the planners were not technically aware of this potential problem at the interface gap at every window opening, and had not asked for Building Control advice at the planning application stage, IBI Group and Studio E should have been aware.”
Approved Document Volume 2 of Part B Fire Safety in the Building Regulations for England and Wales
Finally, Ian questions the wording of Paragraph 12.7, subtitled “Insulation Materials/Products”:
‘In a building with a storey 18m or more above ground level any insulation product, filler material (not including gaskets, sealants and similar) etc. used in the external wall construction should be of limited combustibility.’
He cautions that it is badly worded.
The “not including” list is open to abuse as products and materials “similar” to gaskets and sealants may be combustible – such as membranes, tapes, sealants and adhesives – combining to form a dangerous level of fire load.

Grenfell Tower Inquiry
Grenfell Tower Inquiry Chairman
The new chairman of the Grenfell Tower inquiry said he is doubtful the process would be as wide-ranging as some residents hope after meeting survivors, many of whom were sceptical about his appointment.
Sir Martin Moore-Bick said his inquiry would look at “basic factual questions” about what caused the fire rather than broader problems.
“I’ve been asked to undertake this inquiry on the basis that it would be pretty well limited to the problems surrounding the start of the fire and its rapid development, in order to make recommendations as to how this sort of thing can be prevented in the future,” he said.

Grenfell Tower Building Cladding
Grenfell Tower manslaughter charges
23 Jun 2017 – Grenfell Tower fire: police considering manslaughter charges.
Detectives say building’s insulation and cladding tiles failed fire safety tests and they are establishing if use was illegal, report The Guardian.
Officers had established the initial cause of the fire was a Hotpoint FF175BP fridge-freezer and that it was not started deliberately.
“Preliminary tests show the insulation samples collected from Grenfell Tower combusted soon after the tests started. The initial test on the cladding tiles also failed the safety tests.”
“What we are being told at the moment by the Building Research Establishment (BRE) is that the cladding and insulation failed all safety tests.”
The Police are reviewing every company involved in the building and refurbishment of Grenfell Tower, and have seized documents and materials from a number of organisations.
UK Prime Minister Theresa May said the government would fund tests on up to 100 towers a day. the DCLG estimates that about 600 high-rises across the UK have been clad.

Please join Architects for Social Housing and share what we collectively know so far about the technical and political decisions that led to the Grenfell Tower fire; reassure residents about the safety of post-war tower blocks against the fear being spread by the media; and discuss how to can counteract this disaster being used by politicians to promote the demolition of London’s council estates for profit.
Everybody welcome, residents, architects, engineers, fire-safety specialists, planners, housing campaigners. Please share widely and invite your friends.
The Truth about Grenfell Tower Event

Architects for Social Housing (ASH) was set up in March 2015 in order to respond architecturally to London’s housing ‘crisis’. ASH are a working collective of architects, urban designers, engineers, surveyors, planners, film-makers, photographers, web designers, artists, writers and housing campaigners operating with developing ideas under set principles.
Grenfell Tower Campaigners for Safety
20 Jun – In an open letter to the UK Prime Minister, London Mayor Sadiq Khan praised May’s decision to open a public inquiry, but urged her “to ensure, in the terms of reference of the Inquiry, that an interim report is published this summer, at the latest, and that the terms of reference include all aspects of fire safety standards and inspection in high-rise towers.” He continued, “I would seek an assurance that if the Inquiry or police investigation finds any individual or organization to have been negligent in their duties, then they will be prosecuted.”
“This issue is not limited to the type of cladding fitted; the material it is attached to and how this has been achieved are also critical factors. It is crucial that other risks from renovation works are urgently and properly investigated, for example protection between floors. And we need to strengthen standards and recall processes around white goods, given the fire risk they can present.”
19 Jun – death toll rises to 79.
Of the 18 people in hospital 9 are in critical care, report the BBC.
Selection of photos released by the Police:
18 Jun – Two women feared dead in the Grenfell Tower tragedy were allegedly threatened with legal action after they campaigned for improved fire safety.
Mariem Elgwahry, 27, and Nadia Choucair, 33, may have received letters ordering them to stop their campaign for improved safety.
Both women were fighting the Kensington and Chelsea Tenant Management Organisation for building improvements, with help from the Radical Housing Network (RHN), The Mirror reports.
RHN told the newspaper: “The TMO’s response was to threaten tenants with legal action and send out letters. Nadia and Mariem would have received them too.”
Last night British Prime Minister Theresa May said she had ordered councils to complete urgent safety checks on all high-rise buildings.

Grenfell Tower Building Faliure
Grenfell Tower Fire Building Failings
At least 58 people are presumed dead in the Grenfell Tower disaster Police confirmed. It is an increase of 28 on the number of confirmed victims.
The building refurbishment is now part of a criminal investigation.
We are trying to focus on building-related issues here, to try to learn from this awful incident and prevent it ever happening again. There are various strands to discuss:
1. analysing what went wrong with the building, from cladding type, cladding fixing, to smoke-filled single stair, fire lobbies, fire doors and the fire alarm.
2. drawing some tentative conclusions, if we wait months until a massive hard-to-digest inquiry report the media focus will have gone and some opportunities for change with it.
3. some suggestions about what needs to happen with other high-rise buildings around the world, but focused on UK council housing in towers.
We certainly don’t have all the answers, therefore welcome expert input from other professionals.
Grenfell Tower Facade Section Build Up on Typical Floor
In more detail:
cladding type – typical floors have 3 main components: windows, rainscreen and ACM panels.
It is the latter that seem to exhibit the most combustion. from outside face inwards: Aluminium sandwich panels appear to have a flammable core, with small air gap allowing chimney effect, and flammable foam insulation behind applied to concrete facade from 1974.
cladding fixing – metal brackets shown on planning portal section, unverified reports of flammable timber battens
single stair – obviously inherently dangerous, but why did it fill with smoke?
fire lobbies – lift and stair share a lobby with flats, see plans
fire doors – if working then should have been negligible smoke in stair (just from when self-closing door is opened for egress)
fire alarm – reports suggest it didn’t go off, why?
Grenfell Tower Building materials from outside in – not fully confirmed as a whole but identified in various cross-referenced reports:
a. Aluminium composite material (ACM) cladding (‘3’ in key – Reynobond PE
note ‘5’ in the elevation key, aluminium rainscreen (white panels) make up about half of the cladding).
In the cropped photo below note how the white rainscreen panels appear more intact than the grey ACM panels, logical as the latter have a greater fire load:
cropped photo by Natalie Oxford, courtesy of wikimedia commons
Further info on cladding regulations in other Western countries:
– German construction companies have been banned from using plastic-filled cladding, such as Reynobond PE, on towers more than 22 metres high since the 1980s.
– US building codes restrict the use of metal-composite panels without flame-retardant cores on buildings above 15 metres.
b. air gap, probably criss-crossed by brackets holding outer ACM panels.
c. Celotex insulation applied to existing concrete walls, assumed to be 150mm of Celotex FR5000 and / or RS5000, no backing substrate shown on planning portal section.
Product datasheet: https://www.celotex.co.uk/products/download/5c73880a-6017-4854-88fe-923fff569a4f notes it is tested with both 12mm fibre cement panes and 2×12.5mm plasterboard. But the section (planning portal) and reports suggest it was installed on the tower without a substrate. If no substrate then the fire test approval appears meaningless.
The reasons it passes the test are therefore different to the product used in the 72-storey The Address, Dubai – where the testing flaws were exposed:
meaningless ACM fire test
It seems the Celotex material may be non-FR PIR. Nevertheless the product is certified with reference to BS8414-2 via the performance criteria of BR135 (product datasheet).
There is some suggestion of a leak from the gas riser, there is not enough information on it to discuss at this stage in our view.
Link ref. tests (BS 8414-2, BR 135 see commentary by Sarah Colwell on pp 13-16 of this IFP magazine issue: Fire Performance of external cladding systems.
The article linked above suggests there are around 5000 blocks of flats in England representing around 300,000 homes, a lot of people especially if extrapolated to the rest fo the world.

Grenfell Tower News – updates at The Guardian
We welcome architectural information regarding the aluminium composite material (ACM) cladding panels – info(at)e-architect.co.uk
An informative well-researched article about the Grenfell Tower aluminium composite cladding in The Guardian:
“Cladding for Grenfell Tower was cheaper, more flammable option. Omnis Exteriors asked to supply cladding £2 cheaper a square metre than fire-resistant type, investigation finds.”
Omnis had been asked to supply Reynobond PE cladding, which is £2 cheaper per square metre than the alternative “fire resistant” Reynobond FR, to the companies that worked on refurbishing Grenfell Tower.
Evidence seems to be mounting of problems in so many aspects related to this fire, from building mismanagement, cost-cutting, equipment failure to bad design. These multiple failures are unacceptable and viewed overall suggest a disrespect to the council tenants.
German construction companies have been banned from using plastic-filled cladding, such as Reynobond PE, on towers more than 22 metres high since the 1980s when regulations were brought in to improve fire safety at residential blocks.
US building codes also restrict the use of metal-composite panels without flame-retardant cores on buildings above 15 metres.
The Fire Protection Association (FPA), an industry body, has been pushing for years for the government to make it a statutory requirement for local authorities and companies to use only fire-retardant material.”
Clearly the UK needs to revise the Building Regulations and commence remedial work on all affected tower blocks.
It is imperative lessons are learnt as soon as possible.
The construction industry knows about problem cladding and should have done so much more to clean up its act.
Combustible core cladding usage should be heavily controlled after all of the lessons, notably from UAE.
Grenfell Tower used aluminium composite cladding with thermal insulation.
There is controversy and lobbying surrounding the use of combustible insulation systems.
Also, towers with a single stair should be demolished, there is always a chance the stair will get blocked or smoke-filled.
The refurbishment was overseen by Studio E Architects, and undertaken by Rydon Ltd. As part of the project, in 2015–2016, the concrete structure received new windows and new cladding.
What remains unclear is the system section and detailing: was there a gap behind the cladding, and if so why not fire stopped at every floor? Cavities are closed at each floor per building regulations but is there some weakness or loophole that allowed the ‘chimneys’ to form?
The work was carried out by Harley Facades of Crowborough, East Sussex, at a cost of £2.6 million.
This fire feels like it will become a sad, major milestone like Ronan Point was for an earlier generation. Ronan Point was a 22-storey Modern tower block in Newham, East London, which partly collapsed in May 1968, killing 4 people. It led to a “complete loss of public confidence in high-rise residential buildings, and major changes in UK building regulations resulted.”
The shadow chancellor, John McDonnell, has released a statement which is worth noting:
“The tragic fire that occurred on Grenfell Tower must never be allowed to happen again. The lessons of Camberwell, Shepherd’s Bush and Southampton have not been learned, and it is the responsibility of government to provide solutions.
The government must now as a matter of urgency lift the housing revenue account borrowing cap to free councils to undertake the urgent retrofitting work required on all existing housing stock found not to meet required safety standards.
Councils must also be given the power, as Labour’s housing manifesto pledges to do, to borrow to invest in council housing on the scale necessary to allow all those living in homes deemed to be unsafe to be properly rehoused.”
The Grenfell Tower refurbishment architects posted a statement on their news page:
“We are deeply shocked and distressed over news of the devastating fire at Grenfell Tower.
Our thoughts are with those that have been affected by this tragic incident, together with all of their relatives and friends.
It would be inappropriate for us to comment or speculate on events on Wednesday morning. We will be available to assist the relevant authorities as and when we are required.

BD magazine notes two Italian architects from the Veneto region are believed to have died in the Grenfell fire: Gloria Trevisan and Marco Gottardi were both working for London architecture practices, they lived together on the 23rd floor.
Radical Housing Network, a London-wide alliance of groups fighting for housing justice, said the Grenfell fire was a tragic consequence of systematic disinvestment in council housing alongside disregard for council tenants safety and their concerns – and called for #JusticeforGrenfell.

Grenfell Tower Fire London Building News
Grenfell Tower Cladding
15 Jun – It emerged the cladding used in Grenfell Tower was behind a rapidly spreading blaze at a tower block in Melbourne in 2014, reports The Guardian. An eighth-floor fire raced up 13 floors to the roof of the 21-storey building in 11 minutes. The spread was “directly associated” with the external cladding, said the fire brigade.
The rapid spread of the Lacrosse building fire, which was sparked by a cigarette on an eighth-floor balcony and raced up 13 floors to the roof of the 21-storey building in 11 minutes, was blamed on flammable aluminium composite cladding that lined the exterior concrete walls. Surely it is time for the construction industry to clean up its act and ban combustible aluminium composite cladding panels.

Major London Building Fire
Grenfell Tower Fire
Massive blaze engulfs 24-storey block of flats in North Kensington, west London.
More than 200 firefighters tackled a massive blaze at a block of flats in west London, with people trapped in their homes. Reports very sadly confirm 12 people have died, with many more injured.
Forty fire engines rushed to Grenfell Tower on the Lancaster West Estate, north Kensington, shortly after 1.15am.
Location: Lancaster West Estate, Latimer Road, North Kensington:
Blazing since around 12.45am GMT, reported the BBC. e-architect posted at 5am GMT and our thoughts are with all affected; the page will be updated once any architectural issues come to light.
The construction industry will need to learn from this fire, and why it happened. The 2009 Lakanal House tower block fire occurred in 2009 in Camberwell, South London. Six people were killed in this twelve storey tower block.
A residents action group report warnings went unheeded by relevant authorities:
“we have posted numerous warnings in recent years about the very poor fire safety standards at Grenfell Tower and elsewhere in RBKC.
ALL OUR WARNINGS FELL ON DEAF EARS and we predicted that a catastrophe like this was inevitable and just a matter of time.”
Grenfell Action Group
A building fire expert advised that floor-to-floor fire spread occurring over full height suggests malpractice has occurred.
The London Mayor has declared it a major incident.

The UK has stringent Building Regulations so the extent of the blaze is surprising. Lessons will have to be learnt – a resident suggested the new external cladding might be partly to blame for extent of fire spread – but for now our thoughts are with the people involved.
