2015-01-31: The beginning of this 21st Century is deeply unsettling … history is catching up on us, and old certainties are crumbling before our eyes …
The recent, extremely violent Paris Hive Attacks … which occurred between Wednesday and Friday (7-9 January 2015) … have again shown that co-ordinated attacks on a small number of carefully chosen, low-level targets can be just as effective in causing widespread social and economic disruption in a City as a single attack on a high-level target. Search for our previous detailed discussion, here, on the 2008 Mumbai ‘Hive’ Attacks.
On this tragic occasion, the attacks happened in Europe … not, as before, in far-off India.
Following the 2001 WTC 9-11 Attacks in New York City … the U.S. National Institute of Standards and Technology (NIST), in 2005 and 2008, recommended that these Building Types should be treated as ‘Risk Priorities’ …
• Tall / High-Rise Buildings ;
• Iconic Buildings ;
• Buildings Having a Critical Function ;
• Buildings Having an Innovative Design.
However, a typical medium-rise office building (in Paris) and off-street supermarket do not fall into the above categories … another indication that the NIST Recommendations must soon undergo a thorough international review and updating.
In the real world, the whole urban and sub-urban infrastructure of a City is at risk from Extreme Man-Made Events … one more risk among significant others, i.e. Hybrid Disasters (e.g. 2011 Fukushima Nuclear Incident), Severe Natural Events (e.g. earthquakes, typhoons, tsunamis) and Complex Humanitarian Emergencies (e.g. mass human migrations, regional famines). And with 50% of the world’s population already living in Cities, and substantial urban population growth projected over the coming decades … it is clear that, in the short to medium term, Cities must become much more resilient. Search for our continuing discussion, here, about Sustainable Urban Resilience.
In this context, compliance solely with the minimal and limited fire safety objectives in current national legislation – from whatever source around the world – is so far from being either adequate or acceptable … that it is no longer worth a moment’s consideration.
A Fire Engineering which is ‘fit for purpose’, i.e. is both ethical and professional, in today’s complex and dynamic Human Environment … has an essential and critical part to play in the realization of a Safe, Resilient and Sustainable Built Environment for All !
… this is how we would like to help you … whether you are an individual, or an organization … whether you are located in Ireland, Italy or Turkey … some other part of Europe, the Arab Gulf Region, India, Japan, China … or wherever !
And … we can, if requested or necessary, work in collaboration with local partners in those different geographical regions.

Fundamentally, the 9-11 World Trade Center Incident in New York (2001) was an Extreme ‘Real’ Fire Event. It presented the International Fire Engineering Community with a catastrophic failure in conventional practices and procedures related to:
Fire Engineering, Structural Engineering, and Architectural Design ;
Human Building Management Systems ;
Emergency Response by Firefighters, Rescue Teams, and Medical Personnel ;
National and Local Organizations Having Authority or Jurisdiction (AHJ’s) ;
… and with the serious problem of entirely inadequate Fire Safety Objectives in the building legislation, model codes and design standards of the most economically advanced countries in the world.
Those people who understand the building design process, and have experience as construction practitioners, have long realised that the lessons from 9-11 must be applied across the full spectrum of building types … not just to tall buildings. Right up to the present day, unfortunately, many people in the International Fire Engineering Community are either unwilling, or unable, to do this.
Furthermore … Fire Engineering, Architectural Design and Structural Engineering must, of urgent necessity, be seamlessly conjoined … with the aim of removing misunderstandings and the wide gaps in client service delivery between the different disciplines.
In 2002, a series of Long-Term 9-11 Survivor Health Studies commenced in the USA … and in 2005 and 2008, the U.S. National Institute of Standards and Technology (NIST) issued a series of Post 9-11 Critical Recommendations concerning the design, construction, management and operation of buildings.
At FireOx International … we have fully integrated this essential design guidance into our frontline fire engineering and architectural practice … we have developed unique and practical solutions for worldwide application, some of which appear in International Standard ISO 21542: ‘Building Construction – Accessibility & Usability of the Built Environment’, published in December 2011.
FireOx International’s Commitment to You
As a necessary response to the New 21st Century Paradigm of Real Extreme Event in a Built Environment which is becoming more and more complex … is subject to climate change and severe weather events … and is vulnerable to malign and malevolent disruption –
WE are committed to … the implementation of a Sustainable Human Environment which is Fire Safe and Secure for All, meaning that an ‘appropriate project-specific fire safety level’ is our fire engineering objective, with ‘human health protection’ targeted as a priority … through the use of innovative, reliability-based and person-centred sustainable design practices and procedures.
What is an ‘Appropriate Fire Safety Level’ in Your Building or Facility ?
It is rarely, if ever, explained to clients/client organizations that the Minimal Fire Safety Objectives in building legislation are focused solely on protecting the ‘interests’ of society, not those of the individual … are, quite often, inadequate and/or flawed … and are, always, revised only after the latest tragedy !
To properly protect Your Interests as a client/client organization … we strongly advise that the Appropriate Level of Fire Safety in Your Building or Facility should exceed the minimal level of safety required by building legislation. We would also caution that, in many jurisdictions (e.g. India), compliance with national building legislation is voluntary.
Which raises the issues of whether or not you will actually get what you pay for, and whether or not the Fire Protection Measures in Your Building or Facility are reliable (in other words, will they perform as intended at the time of a ‘real’ fire, which may occur at any time in a building’s long life cycle) !?! Competent Technical Control of Design and Construction, independent of the design and construction organization(s), is essential.
You should carefully consider the following spectrum of issues which may be directly relevant to Your Project. Following a process of consultation with you, we then develop Project-Specific Fire Engineering Design Objectives … bearing in mind that you must also comply with safety at work, anti-discrimination, and environmental legislation, etc … maintain business continuity, etc … be energy efficient, etc … and be socially responsible, etc …
– Protection of the Health of All Building Users … including People with Activity Limitations (2001 WHO ICF), Visitors to the building or facility who may be unfamiliar with its layout, and Contractors or Product/Service Suppliers temporarily engaged in work or business transactions on site ;
– Protection of Property from Loss or Damage … including the Building or Facility, its Contents, and Adjoining or Adjacent Properties ;
– Safety of Firefighters, Rescue Teams and Other Emergency Response Personnel ;
– Ease and Reasonable Cost of ‘Effective’ Reconstruction, Refurbishment or Repair Works after a Fire ;
– Sustainability of the Human Environment (social – built – virtual – economic) … including Fitness for Intended Use and Life Cycle Costing of fire engineering related products and systems, etc … fixed, installed or otherwise incorporated in the building or facility ;
– Protection of the Natural Environment from Harm, i.e. Adverse or Damaging Impacts.

… the Design Professional in Responsible Charge – usually the lead architect – ensures that the (Design) Team Members use consistent design data and assumptions, co-ordinates overlapping specifications, and serves as the liaison with enforcement and review officials, and with the client or client organization. ]
2012-04-16: Following the 9-11 World Trade Center Extreme Fire Event, in New York City …
The National Institute of Standards & Technology (NIST), in the USA, recommended that Fire-Induced Progressive Collapse be particularly considered in the case of …
High-Rise Buildings ;
Iconic Buildings ;
Buildings Having a Critical Function ;
Buildings of Innovative Design.
However, as recently discussed … in order to avoid the wide confusion which the term ‘Fire-Induced Progressive Collapse’ is continuing to cause at international level … the preferred term should now be Fire-Induced Progressive Damage.
AND … CIB Working Commission 14: ‘Fire Safety’ – Research Working Group IV: ‘Structural Reliability & Fire-Induced Progressive Damage’ … would strongly caution that Fire-Induced Progressive Damage and Disproportionate Damage are fundamental concepts to be applied in the design of all building types.
[ A height threshold of 5 Storeys for the consideration of Disproportionate Damage, in the Building Codes/Regulations of many jurisdictions, including Ireland, is entirely arbitrary.]
So … what is Fire-Induced Progressive Damage ? And what is the relationship between this structural concept … and Disproportionate Damage ?
Leaving aside all of the crazy conspiracy theories about the collapse of World Trade Center Building No. 7 … is it possible for Conventional Fire Engineering to directly confront what actually happened ? Unfortunately … the reaction still, even today, is to bury the head, ostrich-like, in the sand … and ignore WTC 7 and the 2008 NIST WTC Recommendations (Final Report NCSTAR 1A) !
Yesterday, on an adjoining page here … I uploaded a New CIB W14 International Reflection Document on ‘Structural Reliability & Fire-Induced Progressive Damage’, with 2 Appendices. Scroll down to the section headed ‘April 2012’.
This is a Reflection Document issued by CIB W14 Research Working Group IV: ‘Structural Reliability & Fire-Induced Progressive Damage’; its purpose is to examine the ‘hot form’ structural concept of Fire-Induced Progressive Damage, and to propose a critical update to fire engineering design practice. It is also intended to encourage a wider discussion about some of fire engineering’s fundamental tenets, and the future direction of our profession in a rapidly evolving trans-disciplinary approach to the design, construction and operation of a Safe and Sustainable Built Environment.
The Document is written in a simple, generic language which is accessible to design disciplines outside the International Fire Science and Engineering Community. The next phase of this CIB W14 Innovation & Research Project will certainly require the use of a more technical language, complex calculations, computer modelling, etc … and much closer liaison with CIB W14’s other Research Working Groups on Connections, Design Fires & Design Fire Scenarios, and Performance Criteria.
I wish to sincerely thank those individuals and organizations who have contributed to the work of our Research Working Group IV.
Finally, the myth surrounding NIST’s 9-11 WTC Recommendations, i.e. that they are only applicable in the case of Very Tall Buildings during rarely occurring extreme events … must be completely demolished, and obliterated from the face of the earth !
Climate Change Adaptation is already demanding a much higher level of building resilience.

Update 2012-04-20 …
In response to a discourteous and unprofessional comment about the above CIB W14 WG IV Reflection Document, posted by Mr. Morgan Hurley (Technical Director at the Society of Fire Protection Engineers in the USA) on the LinkedIn SFPE Group WebPage … I wrote, as follows, this morning …
Good Man Morgan !
Relax … there is no need to become defensive quite yet. WG IV’s Reflection Document is simply intended to raise issues … ask questions … and solicit comments from within and, more importantly, from outside the International Fire Science and Engineering Community.
Perhaps of more direct relevance to the SFPE Membership, in the USA, might be the following …
NIST Report: ‘Best Practices for Reducing the Potential for Progressive Collapse in Buildings’ (NISTIR 7396 – February 2007) … is a good document on ‘disproportionate damage’, but it has nothing to say about ‘fire-induced progressive damage’. These two structural concepts are related, but they are not the same.
When discussing Multi-Storey Steel Frame Buildings, on pages 18 and 19, of NIST Report: ‘Best Practice Guidelines for Structural Fire Resistance Design of Concrete and Steel Buildings’ (NISTIR 7563 – February 2009) … what happened to WTC Building 7 on 9-11, and the 2008 NIST WTC Recommendations (NIST NCSTAR 1A), are conveniently and completely ignored. Instead, there is a launch straight into the BRE Fire Tests at Cardington, and computer calculations, in order to justify a very flawed design approach. How crazy is that ?
Hope to see you there next week … we missed you at the last CIB W14 Meeting in Paris !
