Indian NBC, Proposed Part 11 on ‘Sustainability’ – December 2012 Consultation

.

Extract From Foreword (Page 7):

‘ Developed nations’ approach to sustainability generally concentrates on energy conservation through high technology innovations, and use of products, materials and designs with lower embodied energy.  Their green ratings are based on intent, which implies expert inputs and simulation.  The Indian construction industry will do better using our traditional wisdom and practices, building in harmony with nature through regional common knowledge, consuming as little as necessary, applying low cost technology innovations, using recycled materials, and recognizing performance (not intent) through easily measurable parameters wherever feasible.’

How Right They Are About Prioritizing ‘Real’ Performance !!

.

And Just Before That Extract Above:

‘ The authentic (my insert !) Indian way of life is aparigraha (minimum possessions), conservation (minimum consumption), and recycling (minimum waste).  These three attributes are the guiding principles for sustainable buildings as well.  With these attributes and its rich heritage, India can make a substantial contribution in this field and eventually lead the world on the path of sustainability.’

An Overly Ambitious Target ?   Perhaps Not.

.

SDI Supporting India’s National Sustainable Buildings Strategy …

We very much welcome this opportunity to make a Submission on India’s Draft Amendment No.1 to the 2005 National Building Code (SP 7:2005) concerning the Proposed Inclusion of a New Part 11 ‘Approach to Sustainability’.

This IS an important development for India … and it DOES mark a substantial contribution to this field, at international level.  We wish that other countries would follow your example … particularly China, the other mushrooming economies in South-East Asia, and the Arab Gulf States.

You may not be aware that Sustainable Design International (SDI) has been specializing in the theory and implementation of a Sustainable Human Environment (social, built, virtual, and economic) since the mid-1990’s.

And, for example … in September 2007, we were invited to make a series of Keynote Presentations to 20 Senior National Decision-Makers, from both the public and private sectors, at a 2-Day Workshop which was organized for us in Lisboa, Portugal.  If invited, we would be delighted to repeat this valuable exercise in Dilli, Bengaluru, and other suitable venues in India.

.

IF India is to lead the world on this particular track, i.e. Sustainable Buildings, a coherent philosophy must be outlined in the Proposed New Part 11 of the National Building Code, and a clear direction must also be given there to decision-makers, e.g. clients/client organizations, and designers.

Certain essential content must be included in Part 11.  With regard to an improved layout of Part 11, please review the attached  SDI Document: ‘SEED Building Life Cycle’ (PDF File, 55 Kb) .

.

Because you have prioritized ‘real’ building performance over pre-construction design ‘intent’, it is appropriate to begin our comments here …

1.   Sustainability Performance Indicators

In order to prioritize ‘real’ performance, the monitoring of actual sustainability performance in completed and occupied buildings must be comprehensive, accurate and reliable.  Indicators of sustainability performance must, therefore, be included in all sections of the Proposed New Part 11.

Sustainability Performance Indicators provide important signposts for decision-making and design in many ways.  They can translate physical and social science knowledge into manageable units of information which facilitate the decision-making and design processes.  They can help to measure and calibrate progress towards sustainable development goals, and sectoral sustainability targets.  They can provide an early warning to prevent economic, social and environmental damage and harm.  They are also important tools to communicate ideas, thoughts and values because, as statisticians say: “We measure what we value, and value what we measure”.

Performance Indicators may be both quantitative and qualitative … but must cover all stages of the building process, i.e. project feasibility and performance specification, spatial planning, design, construction, management, operation, maintenance and servicing, de-construction, disposal, final site clean-up and sustainable repair.

While many, though not all, types of building performance can be successfully monitored using lightweight portable equipment … a certain number of monitoring devices must also be permanently installed in the building during construction.  A facility to reliably feed the output from these devices back to data collection points, on site and remote, must also be incorporated in the Building’s Intelligent Management System.

Management and collation of sustainability performance data must be reliable.  Uncertainty is always present.  Therefore, Statements of Uncertainty should always be attached to ‘reliable’ data.

Safety Factors should always be included when targeting critical ‘health and safety’ related types of performance.

Sustainability Performance Indicators must be directly comparable across different Global Regions … within Asia, across different countries … and within India, across different States.  A Balanced, Harmonized Core Set of Indian Performance Indicators should be quickly developed.  A Balanced ‘Local’ Set of Performance Indicators will always be necessary.

People tasked with monitoring sustainable building performance must be competent … and independent, i.e. be unconnected to client, design and construction organizations.

Specifically in relation to Energy Performance, the targets to be achieved in new buildings must be far more ambitious.  Please review the attached  SDI Document: ‘SEED Positive Energy Buildings’ (PDF File, 29 Kb) .

.

2.   Properly Defining ‘Sustainable Development’

As currently drafted … Definition 2.26 Sustainable Development, on Page 13 of the Proposed New Part 11, is not only ambiguous, it is inadequate for India’s needs … and it is barely the first half of the full, correct definition …

Sustainable Development  is development that meets the needs of the present without compromising the ability of future generations to meet their own needs.  It contains within it two key concepts:

  • the concept of ‘needs’, in particular the essential needs of the world’s poor, to which overriding priority should be given ;  and
  • the idea of limitations imposed by the state of technology and social organization on the environment’s ability to meet present and future needs.

[ Please refer to the 1987 Report of the World Commission on Environment & Development (WCED): ‘Our Common Future’ – Chapter 2, Paragraph 1.]

This original definition in the 1987 WCED Report IS appropriate for India … and it must become the core definition at the heart of India’s National Sustainable Buildings Strategy !

A careful reading of the full definition makes it clear that there are Many Aspects to this intricate, open, dynamic and still evolving concept … the most important of which are:  Social, Economic, Environmental, Institutional, Political, and Legal.

It is a Fundamental Principle of Sustainability, and one of its Primary Values … that Implementation must be Synchronous, Balanced and Equitable across All Aspects of Sustainability.

The ‘Green Agenda’ merely considers Environmental Aspects of Sustainability … in isolation from all of the other Aspects !   This is a fatal flaw which must be avoided in the Proposed New Part 11 !!

[ I made many references to this issue during the FSAI Conferences in India ! ]

.

3.   Sustainability Impact Assessment (SIA) for India !

Rather than Environmental Impact Assessment … surely the Proposed New Part 11: ‘Approach to Sustainability’ must now use, explain and discuss Sustainability Impact Assessment instead !?!

Sustainability Impact Assessment (SIA)

A continual evaluation and optimization assessment – informing initial decision-making, or design, and shaping activity/product/service realization, useful life and termination, or final disposal – of the interrelated positive and negative social, economic, environmental, institutional, political and legal impacts on the synchronous, balanced and equitable implementation of Sustainable Human & Social Development.

. 

4.   A Robust Legal Foundation for ‘Sustainable Human & Social Development’

Paragraph 4 (Chapter 2, 1987 WCED Report) states …

‘ The satisfaction of human needs and aspirations is the major objective of development.  The essential needs of vast numbers of people in developing countries – for food, clothing, shelter, jobs – are not being met, and beyond their basic needs these people have legitimate aspirations for an improved quality of life.  A world in which poverty and inequity are endemic will always be prone to ecological and other crises.  Sustainable development requires meeting the basic needs of all and extending to all the opportunity to satisfy their aspirations for a better life.’

Trying to list the essential needs of people / the basic needs of all is a very difficult task … but it is work which has been on-going, at international level, since just after the Second World War.

The essential needs of people / the basic needs of all … are specified as being Human Rights and Fundamental Freedoms, and are already fully described within the extensive framework of International Legal Rights Instruments.

Which is why, many years ago, SDI developed this definition for Sustainable Human & Social Development … in order:

  • to give this concept a robust legal foundation ;   and
  • (because of widespread confusion in media, political and academic circles) … to clearly establish that we are talking about sustainable human and social development, and not sustainable economic development, or any other type of development !

Sustainable Human & Social Development

Development which meets the responsible needs, i.e. the Human & Social Rights*, of this generation – without stealing the life and living resources from future generations … especially our children, and their children … and the next five generations of children.

*As defined in the 1948 Universal Declaration of Human Rights.

.

5.   Climate Change Adaptation & Resilient Buildings in India ?

Atmospheric Ozone Depletion and Climate Change are mentioned, here and there, in the Proposed New Part 11.  The important implications of these phenomena for Sustainable Building Design in India are not explained … at all.  Why not ?

To properly respond to these phenomena, both must be integrated into India’s National Sustainability Strategies & Policies.

At the very least … we strongly recommend that Design Guidance on Climate Resilient Buildings be immediately drafted.  This guidance must be appropriate for implementation in each of the different climatic regions of India.

.

6.   A Sustainable Indian Built Environment which is Accessible for All !

Barrier Free is mentioned, here and there, in the Proposed New Part 11.  This is to be warmly welcomed and congratulated.  Under Social Aspects of Sustainable Human & Social Development … this is an essential attribute of a Sustainable Built Environment !   However, no guidance on this subject is given to decision-makers or designers.  Why not ?

However, you should be aware that India ratified the United Nations Convention on the Rights of Persons with Disabilities (UN CRPD) on 1 October 2007.  For your convenience, I have attached copies of the Convention in English, Hindi and Tamil.

You should also be aware that, in December 2011, the International Standards Organization (ISO) published ISO 21542: ‘Building Construction – Accessibility & Usability of the Built Environment’.  In its Introduction, ISO 21542 is directly linked to the U.N. Convention … almost like an umbilical cord.  The scope of this Standard currently covers public buildings.  As the Accessibility Agenda in the U.N. Convention is very broad … much standardization work remains to be finished at international level.

The correct term … Accessibility for All … has been defined in ISO 21542 as including … ‘access to buildings, circulation within buildings and their use, egress from buildings in the normal course of events, and evacuation in the event of an emergency’.

A note at the beginning of the standard also clarifies that Accessibility is an independent activity, i.e. assistance from another person should not be necessary … and that there should be an assurance of individual health, safety and welfare during the course of those (accessibility-related) activities.

In order to fulfil India’s legal obligations as a State Party to the U.N. Convention on the Rights of Persons with Disabilities … adequate Design Guidance on Accessibility must be included in the Proposed New Part 11, supported by ISO 21542.

In addition, the Bureau of Indian Standards (BIS) should immediately adopt ISO 21542 as the Indian National Standard on Accessibility for All … IS / ISO 21542.

[ I made many references to this issue during the FSAI Conferences in India ! ]

.

7.   Fire Safety & Protection for All in Sustainable Indian Buildings ?

Yes … there is 1 mention of ‘fire safety’ and 40 other references to ‘fire’ in the Proposed New Part 11 … but no design guidance.  Why not ?

You should be aware that there is a fundamental conflict between Sustainable Building Design Strategies and the current state-of-the-art in Fire Engineering Design.  As a good example … for cooling, heating and/or ventilation purposes in a sustainable building, it is necessary to take advantage of natural patterns of air movement in that building.  On the other hand, fire engineers in private practice, and fire prevention officers in Authorities Having Jurisdiction (AHJ’s), will demand that building spaces be strictly compartmented in order to limit the spread of fire and smoke … thereby dramatically interfering with those natural patterns of air movement.

In everyday practice, there is a vast chasm in understanding and communication between these two very different design disciplines.  As a result, serious compromises are being enforced on Sustainability Building Performance.  If, on the other hand, adequate independent technical control is absent on the site of a Sustainable Building … it is the fire safety and protection which is being seriously compromised.

A range of critical fire safety issues (fatal, in the case of firefighters) are also arising with the Innovative Building Products and Systems being installed in Sustainable Buildings.

Because the emphasis is on pre-construction design ‘intent’ rather than the ‘real’ performance of the completed and occupied building … all of these problems are being conveniently ignored, and they remain hidden from everybody’s view.

This must be addressed in the Proposed New Part 11.

Ireland’s Draft National Radon Control Strategy – A Fraud !!

2013-02-28:  Submissions on Ireland’s Draft National Radon Control Strategy must arrive at the Department of the Environment, Community & Local Government, our national authority having jurisdiction … by e-mail or hand delivery to either the Custom House in Dublin or the DECLG Offices in Wexford … no later than 17:30 hrs tomorrow, Friday 1 March 2013

DECLG - Draft National Radon Control Strategy Title Page (January 2013)

Ireland’s Draft National Radon Control Strategy – January 2013 Consultation

Click the Link above to read/download PDF File (425 Kb)

The Aim of this Draft Strategy, as stated on the DECLG WebSite, is to ensure that exposure to Radon Gas, which presents a significant public health problem, is addressed in an effective and co-ordinated way across all relevant public authorities through appropriate interventions.  The Draft Strategy was developed by an Inter-Agency Group comprising representatives from relevant public authorities.

.

After all of the progress made on radon protection in buildings at the end of the 1990’s and beginning of the 2000’s, it is extremely disappointing to read this miserable excuse for a strategy document.  If the general public in Ireland is under any impression that the ‘powers-that-be’ are deeply concerned about protecting our health … they are making a fatal mistake !

The complete absence of any reference to a Recommended Health-Related Radon Target Level – Safety-Related National Reference Levels which are not clearly explained will result in some injury and harm – Lack of Meaningful Consultation with, and Informed Consent of, the National Population – Horrendously Inadequate Technical Control Procedures on Irish Building Sites – RPII Recommended Indoor Radon Activity Measuring Devices having Very High Measurement Uncertainty (±30% under typical conditions of use) – A Purposeful Lack of Detailed Guidance on Exactly When and How to Measure Indoor Radon – Inadequate RPII Radon Measurement Test Reporting … are just some of the tell-tale signs for a seasoned observer.

In this regard, therefore … and let me be very clear and simple in my use of language … this Draft National Radon Control Strategy is a blatant fraud !!

Fraud:  Deliberate deception, trickery, or cheating intended to gain an advantage – An act or instance of such deception (from Latin Fraus (f): deceit, deception).

Furthermore … the Inter-Agency Group which produced this Draft National Radon Control Strategy for the DECLG Minister, Mr. Phil Hogan T.D., and Senior Civil Servants within the Department … whoever the Group’s participants are, wherever they are … should be thoroughly ashamed of themselves for being associated with this negligent act !

Negligent:  Lacking attention, care or concern.

Negligence:  A wrong whereby a person(s) is in breach of a legal duty of care, resulting in harm or injury to another person(s) … in this case, the Irish Public.

To see a complete overview on this Serious Building-Related Human Health Issue, and for information about a Far Better and More Coherent Approach to Radon Protection in Buildings which takes proper account of European Union (E.U.) legislation, e.g. the Precautionary Principle … please refer to SDI’s Corporate WebSite

(It is not my intention to reproduce, here, all of the content on this WebPage as part of the Submission.)

I am also the Technical Consultant who drafted these 2 Benchmark Irish Agrément Board (IAB) Certificates for Radon Protection Measures in Buildings …

SDI’s Comments on Ireland’s Draft National Radon Control Strategy (NRCS)

1.   Protecting Human Health versus Reducing Risk to Safety

The following two short extracts from 1. Introduction and Background in the Draft NRCS reveal the true intent of the Inter-Agency Group …

‘ Radon gas is the greatest source of exposure to ionising radiation for the general public and is the second greatest cause of lung cancer in Ireland.  Recognising the serious health risk presented by radon, the Minister for the Environment, Community and Local Government in November 2011 established an inter-agency group to develop a National Radon Control Strategy (NRCS).’

and …

‘ During 2012 the inter-agency group developed a draft NRCS based on wide stakeholder consultation and a health economics evaluation of different radon intervention strategies.  The stakeholder consultation involved a range of individuals and bodies involved in: health care, construction, radon services, Government and academia.  The health economics evaluation was undertaken by the Radiological Protection Institute of Ireland (RPII) and Health Service Executive (HSE) with the assistance of the Health Economics Unit at the University of Oxford.  This draft strategy sets out a range of measures to reduce the risk from radon to people living in Ireland.’

Radon is a serious human health issue, and it is explained in a later section of the document 1.2 The Radon Problem in Ireland that ‘indoor radon is linked to between 150 to 200 lung cancer deaths each year in Ireland, which equates to approximately 13% of all lung cancer deaths.’

However … after the references above to ‘health economics evaluation’ (!) … to the ‘prevailing  economic situation’ (!!) in section 1.1 Public Consultation … and to ‘health economics tools’ (!!!) in section 2. Draft National Radon Control Strategy … etc … you should then sensitize yourself to the subtle change in language very early in the document … from a consideration of health protection, to reducing the risk from radon (or similar variations on that theme).

The concept of Protecting Human Health is altogether different from the concept of Assessing and Mitigating / Reducing Risk to Safety !   Please refer to SDI’s Corporate WebSite.

As far back as the end of the 1990’s … the Irish Agrément Board, which at the time included a representative from the Department of the Environment, accepted the following …

Radon Activity in Buildings – Recommended Target Health Level

Radon Activity (incl. Rn-222, Rn-220, RnD) should, on average, fall within the range of 10-40 Bq/m3, but should at no time exceed 60 Bq/m3.

This Recommended Target Health Level for Radon now also appears in International Standard ISO 21542: ‘Building Construction – Accessibility & Usability of the Built Environment’, which was published in December 2011.  Please refer to Annex B.8 – Indoor Air Quality (IAQ) in the ISO Standard.

The Draft NRCS must refer to such a Recommended Target Health Level … and it must be stated that it is National Policy to progressively reach that target by 2025 (bearing in mind the ‘prevailing economic situation’ in the country !).

Note:  In contrast to the above … 200 Bq/m3 for Residential Buildings, and 400 Bq/m3 for Workplaces … are NOT Health-Related Target Levels … they are Safety-Related National Radon Reference Levels which result in some measure of harm and injury to people … particularly children under the age of 10 years, and people with activity limitations who constantly remain indoors for prolonged periods of time.

.

2.   National Policy Priority:  ‘Real’ Protection from Radon in ‘Real’ Irish Buildings

Yes … in Ireland, we have enormous problems with regard to a lack of awareness among the general population about the serious health hazard posed by indoor radon … and the absence of proper education and training for everyone directly involved in the design, construction, management, operation, servicing or maintenance of our building stock (both new and existing).

BUT … if we are committed to providing ‘real’ radon protection in ‘real’ Irish buildings, then a practical construction-oriented approach is demanded.

This is a Key Paragraph in 2.1 Radon Prevention in New Buildings

‘ The stakeholder engagement also points to some practical difficulties associated with the implementation of the current technical guidance on radon prevention.  These difficulties relate to the correct installation of radon barriers under site conditions, protection of the integrity of radon barriers once installed and identification of radon preventive measures on site.  The stakeholder engagement also indicated the system of building control in place prior to 2012 did not provide adequate assurance that radon preventive measures had been correctly installed ‘

… which we later discover is a masterstroke of understatement and evasion, because none of these important issues are tackled head on in the document.

On the critical issue of Building Control … there is no mention of mandatory inspections of construction projects by competent Local Authority personnel.  Because … it remains the unwritten policy of Ministers and Senior Civil Servants in Ireland’s Department of the Environment, Community & Local Government (DECLG) that Local Authority Building Control Sections will be entirely ineffective.

On the other hand … will Competent Private Independent Technical Controllers be facilitated in carrying out sufficient inspections of all radon protection related works before ‘signing off’ on proper completion ???

.

3.   Regulatory Status of RPII’s Radon Prediction Maps

This is NOT a problem unique to Ireland.

The presence of the RPII Radon Prediction Maps in Technical Guidance Document C (Building Regulations), and the status they are given there … are both entirely inappropriate.

While these Maps are a useful design aid, in the case of small construction projects, they offer NO assurance of certainty to either building designers or users.  They are NOT reliable !   And the average values shown in any particular ‘box’ may actually conceal a considerable degree of variability in the radon concentrations found in completed buildings.

.

4.   SDI’s Acceptance of RPII Services

Please refer to SDI’s Corporate WebSite.

Unfortunately, until the Radiological Protection Institute of Ireland (RPII) includes proper statements of Measurement Uncertainty in its Test Reports (this is a requirement of European Standard EN ISO/IEC 17025)  … our Organization:

  • cannot recommend any RPII Radon Testing Services to 3rd Parties ;

and

  • will not accept any RPII Test Reports as proper evidence of Radon Test results.

Sick Building Syndrome, ISO 21542:2021 & Indoor Air Quality (IAQ)

2012-05-31 (2021-08-02):  The Revised International Standard  ISO 21542: ‘Building Construction – Accessibility & Usability of the Built Environment’  was published on 1 June 2021.  Many years before, however, a decision was taken to link this Standard directly to the United Nations  Convention on the Rights of Persons with Disabilities  (#CRPD) … specifically now referencing Preamble Paragraph (g) and Articles 9, 10, 11, 12 and 19 in its Introduction.  Reading the document, this linkage looks and feels very naturally like an unbreakable umbilical cord !

.

Black and White image showing the Title Page of International Standard ISO 21542: ‘Building Construction – Accessibility & Usability of the Built Environment’, which was published on 1 June 2021.  Click to enlarge.

.

ISO 21542 has significantly widened the meaning of the concept #Accessibility4ALL … a normal evolutionary process … in particular, the #FireSafety4ALL Texts.  I wonder, though, how many people would ever have considered  Good Indoor Air Quality  to be on the ‘Accessibility’ Menu ??

.

Colour image showing a young child wearing a face mask (#Pandemic #CoronaVirus #CoVID19) … with an accompanying text: ‘Poor Indoor Air Quality Is A Serious Threat’.  Click to enlarge.

.

Much lower rates of direct fresh air ventilation … and a dramatic reduction in accidental or unintended air seepage from, or into, buildings (depending on local climate conditions) … all driven by an urgent need to conserve energy and to impose greater energy efficiencies on the energy which is actually consumed … are, once again, one of the main causes of serious health problems for ALL #BuildingUsers …

Building Related Ill-Health:  Any adverse impact on the health of building users – while living, working, generally occupying or visiting a specific building – caused by the planning, design, construction, management, operation or maintenance of that building.

I say “once again” because, in Europe, we have been here before … after the two big oil crises of the 1970’s.

.

Anyway … I thought that it would be useful to present a relevant extract from ISO 21542

B.8 – INDOOR AIR QUALITY (#IAQ)

Poor indoor air quality, an important factor in relation to Building Related Ill-Health (also known as ‘sick building syndrome’), can cause serious health impairments and severely restrict a person’s participation in everyday activities, e.g. work.

Symptoms and signs may include:

  • irritation of eyes, nose and throat ;
  • respiratory infections and cough ;
  • voice hoarseness and wheezing ;
  • asthma ;
  • dry mucous membrane and skin ;
  • erythema (reddening or inflammation of the skin) ;
  • lethargy ;
  • mental fatigue and poor concentration ;
  • headache ;
  • stress ;
  • hypersensitivity reactions, i.e. allergies ;
  • nausea and dizziness ;
  • cancers.

These symptoms and signs are present in the population at large, but are distinguished by being more prevalent in some building users, as a group, when compared with others.  The symptoms and signs may disappear, or may be reduced in intensity, when an affected person leaves the building.  It is not necessary that everyone in a building should be affected before building related ill-health is suspected.

ISO 16814: ‘Building Environment Design – Indoor Air Quality – Methods of Expressing the Quality of Indoor Air for Human Occupancy’ covers methods of expressing indoor air quality (IAQ) and incorporating the goal of achieving good IAQ into the building design process.  It also covers ventilation effectiveness, harmful emissions from building materials, air cleaning devices, and heating, ventilation and air conditioning equipment.

The indoor pollutants considered in ISO 16814 include human bio-effluents, which have often been the principal consideration in air quality and ventilation design, but also the groups and sources of pollutants which can reasonably be anticipated to occur in the building during its long Life Cycle.

These pollutants, depending on the sources present, may include:

  • volatile organic compounds (#VOC’s) and other organics, such as formaldehyde ;
  • environmental tobacco smoke (#ETS) ;
  • natural radon, consisting of a number of different isotopes, is an invisible radioactive gas, and is found in the soils under buildings, water supplies to buildings and in the air ;
  • other inorganic gases, such as carbon monoxide (#CO), the oxides of nitrogen (NOx), and low-level ozone (smog) which is formed when NOx and VOC’s react in the presence of sunlight ;
  • viable particles, including viruses, bacteria and fungal spores ;
  • non-viable biological pollutants, such as particles of mites or fungi and their metabolic products ;
  • non-viable particles, such as dusts and fibres.

The following Two Performance Indicators of Good Indoor Air Quality, developed with the aim of protecting human health, are recommended:

  1. Radon Activity (including Rn-222, Rn-220, RnD)  in a building should, on average, fall within the range of 10-40 Bq/m3, but should at no time exceed 60 Bq/m3.
  2. Carbon Dioxide (CO2)  concentrations in a building should not significantly exceed average external levels – typically within the range of 300-500 parts per million (#PPM) – and should at no time exceed 800 ppm.

[ While the current CoVID-19 Pandemic lasts … these are Essential ‘Health’ Performance Indicators, as opposed to ‘Safety’ Indicators … and they should be stringently operated and constantly monitored in all building types. ]

Conventional Structural Fire Engineering Design – How Flawed ?

2012-05-18:  Déjà-vu …

” In the early hours of the morning of Saturday, 14th February 1981, a disastrous fire swept through a building called the Stardust in the North Dublin suburb of Artane during the course of a St. Valentine’s Night ‘disco’ dance.  Forty eight people were killed and one hundred and twenty eight seriously injured.  The overwhelming majority of the victims were young people. “

‘Introduction’, Report of the Tribunal of Inquiry on the Fire at the Stardust, Artane, Dublin, on the 14th February 1981.  Report dated 30 June 1982.

As a young architect in private practice … I witnessed, at first hand, the Dublin Fire ‘Establishment’ disappear from public view, without trace, after the Stardust Fire Tragedy.  It was almost impossible, for at least a year afterwards, to have a meeting with any Fire Prevention Officer in the Dublin Fire Authority.  This was a very valuable lesson.

Later, following the publication of the Stardust Tribunal Report … were its Recommendations implemented … with urgency … and conscientiously ?   No way.  For example, it was more than ten years after the Stardust Fire before an inadequate system of legal National Building Regulations was introduced in Ireland.  And to this day, the system of AHJ monitoring of construction quality, throughout the country, is weak and ineffective … lacking both competent personnel and resources !

The proof of the pudding is in the eating … and one of the results, also in Dublin, has been last year’s debacle at the Priory Hall Apartment Complex … where all of the residents had to leave their expensive apartments for fire safety (and many other) reasons.  The tip of a very large iceberg.  See my post, dated 18 October 2011 .

And this is where the problems usually begin …

” There has been a tendency among students of architecture and engineering to regard fire safety as simply a question of knowing what is required in terms of compliance with the regulations.  The recommendation of the Tribunal of Enquiry into the Summerland Disaster that those responsible for the design of buildings should treat fire safety as an integral part of the design concept itself, has not yet been reflected in the approach to the subject at university level.  There is still clearly a need for a new approach to the structuring of such courses which will in time bring to an end the attitude of mind, too prevalent at the moment, that compliance with fire safety requirements is something that can be dealt with outside the context of the overall design of the building. “

‘Chapter 9 – Conclusions & Recommendations’, Report of the Tribunal of Inquiry on the Fire at the Stardust, Artane, Dublin, on the 14th February 1981.  Report dated 30 June 1982.

This Recommendation has still not been implemented … and note the reference to the earlier fire at the Summerland Leisure Centre in 1973, on the Isle of Man, when 50 people were killed and 80 seriously injured.

Today … the same attitude of mind, described so well above, stubbornly persists in all sectors, and in all disciplines, of the International Construction Industry … even within ISO Technical Committee 92: ‘Fire Safety’ !

.

Which brings me, neatly, to the recent question posed by Mr. Glenn Horton on the Society of Fire Protection Engineers (SFPE-USA) Page of LinkedIn ( http://www.linkedin.com/groups?gid=96627 ).   As usual, the shortest questions can prove to be the most difficult to answer …

” Can you expand on, or point to where anyone has discussed, the ‘very flawed design approach’ please ? “

.

ESSENTIAL PRELIMINARIES …

     1.  Foundation Documents

I am assuming that ‘people-who-need-to know’, at international level, are familiar with the Recommendations contained in these 2 Reports …

  • NIST (National Institute of Standards and Technology).  September 2005.  Federal Building and Fire Safety Investigation of the World Trade Center Disaster: Final Report on the Collapse of the World Trade Center Towers.  NIST NCSTAR 1   Gaithersburg, MD, USA ;

and

  • NIST (National Institute of Standards and Technology).  August 2008.  Federal Building and Fire Safety Investigation of the World Trade Center Disaster: Final Report on the Collapse of World Trade Center Building 7.  NIST NCSTAR 1A   Gaithersburg, MD, USA ;

… and the contents of the CIB W14 Research WG IV Reflection Document … which, together with its 2 Appendices, can be downloaded from this webpage … https://www.cjwalsh.ie/progressive-collapse-fire/ … under the section headed: ‘April 2012’.

However … I am utterly dismayed by the number of ‘people-who-need-to know’ … who do not know … and have never even bothered to dip into the 2 NIST Reports … or the many long-term Post 9-11 Health Studies on Survivors which have already revealed much priceless ‘real’ information about the short and medium term adverse impacts on human health caused by fire !

CIB W14 Research Working Group IV would again strongly caution that Fire-Induced Progressive Damage and Disproportionate Damage are fundamental concepts to be applied in the structural design of all building types.

     2.  Technical Terminology

While attending the ISO TC92 Meetings in Thessaloniki, during the last week of April 2012, I noticed not just one reference to ‘fire doors’ in a Draft ISO Fire Standard … but many.  It surprised me, since I thought this issue had been successfully resolved, at ISO level, many years ago.  There is no such thing as a ‘fire door’ … and the careless referencing of such an object, which has no meaning, in building codes and standards has caused countless problems on real construction sites during the last 20-30 years.

Please follow this line of thought …

Fire Resistance:  The inherent capability of a building assembly, or an element of construction, to resist the passage of heat, smoke and flame for a specified time during a fire.

Doorset:  A building component consisting of a fixed part (the door frame), one or more movable parts (the door leaves), and their hardware, the function of which is to allow, or to prevent, access and egress.

[Commentary: A doorset may also include a door saddle / sill / threshold.]

Fire Resisting Doorset / Shutter Assembly:  A doorset / shutter assembly, properly installed or mounted on site, the function of which is to resist the passage of heat, smoke and flame for a specified time during a fire.

… and so we arrive at the correct term … Fire Resisting Doorset … which, as an added bonus, also alerts building designers, construction organizations, and even AHJ inspectors, to the fact that there is more involved here than merely a door leaf.

Now then, I wonder … how, in any sane and rational world, can the term Fire Resistance be used in relation to structural performance during a fire, and the cooling-phase afterwards ?   Yet, this is exactly what I read in the building codes of many different jurisdictions.  Do people understand what is actually going on ?   Or, is the language of Conventional Fire Engineering so illogical and opaque that it is nearly impossible to understand ?

And … if this problem exists within the International Fire Science & Engineering Community … how is it possible to communicate effectively with other design disciplines at any stage during real construction projects.  The artificial environments found in academia are not my immediate concern.

.

     3.  Fire Research & Development outside CIB W14 & ISO TC92

In 2012 … there is something very wrong when you have to struggle to persuade a group of people who are developing an ISO Standard on Design Fire Scenarios … that they must consider Environmental Impact as one of the major consequences of a fire to be minimized … along with ‘property losses’ and ‘occupant impact’.  This is no longer an option.

Environmental Impact:  Any effect caused by a given activity on the environment, including human health, safety and welfare, flora, fauna, soil, air, water, and especially representative samples of natural ecosystems, climate, landscape and historical monuments or other physical structures, or the interactions among these factors; it also includes effects on accessibility, cultural heritage or socio-economic conditions resulting from alterations to those factors.

So … how timely, and relevant to practitioners, are ISO Fire Standards ?   Perhaps … obsolete at publication … and not very ??

And … there is lot more to the Built Environment than buildings …

Built Environment:  Anywhere there is, or has been, a man-made or wrought (worked) intervention in the natural environment, e.g. cities, towns, villages, rural settlements, service utilities, transport systems, roads, bridges, tunnels, and cultivated lands, lakes, rivers, coasts, and seas, etc … including the virtual environment.

.

We should be very conscious that valuable fire-related research takes place outside, and unrelated to, the established fire engineering groupings of CIB W14 & ISO TC92.  But I am curious as to why this research is not properly acknowledged by, or encouraged and fostered within, the ‘system’ ?

Example A:  Responding to Recommendation 18 in the 2005 NIST WTC Report … a Multi-Disciplinary Design Team published an article in the magazine Bâtiment et Sécurité (October 2005) on The PolyCentric Tower.  I very much enjoy giving practitioners a small flavour of this work, whenever I make presentations at conferences and workshops …

.

Example B:  In spite of a less than helpful submission (to put it mildly) from ISO TC92 Sub-Committee 4 … ISO 21542: ‘Building Construction – Accessibility & Usability of the Built Environment’ was finally published in December 2011 … but it was developed by a Sub-Committee of ISO TC59: ‘Buildings & Civil Engineering Works’

Colour image, from one of my Overhead Presentations ... showing the design of a notional Fire Evacuation Staircase, with an adjoining Area of Rescue Assistance, which responds directly to the 2005 NIST WTC Recommendations. See Figure 62 in ISO 21542:2011. Click to enlarge.

.

With the involvement and support of ISO Technical Committee 178: ‘Lifts, Elevators & Moving Walks’ during its long gestation … ISO 21542 is now able to indicate that all lifts/elevators in a building should be capable of being used for evacuation in the event of a fire.  This is already a design feature in a small number of completed Tall Building Projects.  Once more, this is no longer an option.

In addition … if a Fire Evacuation Staircase has a minimum unobstructed width of 1.5 m (from edge of handrail on one side of the staircase to edge of handrail on the opposite side) … this will be sufficient to facilitate the following tasks …

  • Assisted Evacuation by others, or Rescue by Firefighters, for those building users who cannot independently evacuate the building, e.g. people with activity limitations … shown above, on the right, is assistance being given by three people (one at each side, with one behind) to a person occupying a manual wheelchair ;
  • Contraflow Circulation … emergency access by firefighters entering a building and moving towards a fire, while people are still evacuating from the building to a ‘place of safety’ remote from the building … shown above, bottom left, is how not to design an evacuation staircase (!) ;
  • Stretcher Lifting … lifting a mobility-impaired person, who may be conscious or unconscious, on a stretcher ;
  • Firefighter Removal & Contraflow … shown above, top left, is removal of a firefighter from a building by colleagues in the event of injury, impairment, or a fire event induced health condition … while other firefighters may still be moving towards the fire.

Note that in a Fire Evacuation Staircase … all Handrails are continuous … each Stair Riser is a consistent 150 mm high … each Stair Tread/Going is a consistent 300 mm deep … and there are No Projecting Stair Nosings.

Most importantly … in order to assign sufficient building user space in the design of an Area of Rescue Assistance … ISO 21542 also provides the following Key Performance Indicator … just one aspect of a ‘maximum credible user scenario’ …

10% of people using a building (including visitors) have an impairment, which may be visual or hearing, mental, cognitive or psychological, or may be related to physical function, with some impairments not being identifiable.

Is There Any Connection Between Examples A & B ?   There is, and it is a connection which is critical for public safety.  The following Performance Indicator illustrates the point …

Innovative Structural Design – Perimeter Core Location – Design for Fire Evacuation – Evacuation for All

” A Building must not only remain Structurally Stable during a fire event, it must remain Serviceable for a period of time which facilitates:

  • Rescue by Firefighters of people with activity limitations waiting in areas of rescue assistance ;
  • Movement of the firefighters and those people with activity limitations, via safe and accessible routes, to Places of Safety remote from the building ;
  • With an assurance of Health, Safety & Welfare during the course of this process of Assisted Evacuation. “

[Refer also to the Basic Requirements for Construction Works in Annex I of the European Union’s Construction Product Regulation 305/2011 – included as Appendix II of the CIB W14 WG IV Reflection Document.  Are the Basic Requirements being interpreted properly … or even adequately ??]

.

ANSWERS TO THE QUESTION …

The Greek Paper is included as Appendix I of CIB W14 WG IV Reflection Document … in order to show that Fire-Induced Progressive Damage is also an issue in buildings with a reinforced concrete frame structure.  It is more straightforward, here, to concentrate on buildings with a steel frame structure.

a)  Use of ‘Fire Resistance'(?) Tables for Structural Elements

We should all be familiar with these sorts of Tables.  The information they contain is generated from this type of standard test configuration in a fire test laboratory …

… and this sort of criterion for ‘loadbearing horizontal elements’ in a fire test standard …

A single isolated loaded steel beam, simply supported, is being tested.  As deflection is the only type of deformation being observed and measured … the critical temperature of the steel, i.e. the point when material strength begins to fail rapidly and the rate of beam deflection increases dramatically … is the sole focus for all stakeholders.

Using these Tables, it is very difficult to escape the conclusion that we are merely interior decorators … applying flimsy thermal insulation products to some steel structural elements (not all !) … according to an old, too narrowly focused, almost static (‘cold form’) recipe, which has little to do with how today’s real buildings react to real fires !

This ‘non-design’ approach is entirely inadequate.

.

With regard to the use of these Tables in Ireland’s Building Regulations (Technical Guidance Document B), I recently submitted the comments below to the relevant Irish AHJ.  These same comments could just as easily apply to the use of similar Tables in the Building Regulations for England & Wales (Approved Document B) …

” You should be aware that Table A1 and Table A2 are only appropriate for use by designers in the case of single, isolated steel structural elements.

In steel structural frame systems, no consideration is given in the Tables to adequate fire protection of connections … or limiting the thermal expansion (and other types of deformation) in fire of steel structural elements … in order to reduce the adverse effects of one element’s behaviour on the rest of the frame and/or adjoining non-loadbearing fire resisting elements of construction.

In the case of steel structural frame systems, therefore, the minimum fire protection to be afforded to ALL steel structural elements, including connections, should be 2 Hours.  Connections should also be designed and constructed to be sufficiently robust during the course of a fire incident.  This one small revision will contribute greatly towards preventing Fire-Induced Progressive Damage in buildings … a related, but different, structural concept to Disproportionate Damage

Disproportionate Damage

The failure of a building’s structural system  (i) remote from the scene of an isolated overloading action;  and (ii) to an extent which is not in reasonable proportion to that action.

Fire-Induced Progressive Damage

The sequential growth and intensification of structural deformation and displacement, beyond fire engineering design parameters, and the eventual failure of elements of construction in a building – during a fire and the ‘cooling phase’ afterwards – which, if unchecked, will result in disproportionate damage, and may lead to total building collapse.

Coming from this background and heritage … it is very difficult to communicate with mainstream, ambient structural engineers who are speaking the language of structural reliability, limit state design and serviceability limit states.

.

b)  NIST Report: ‘Best Practice Guidelines for Structural Fire Resistance Design of Concrete and Steel Buildings’ (NISTIR 7563 – February 2009)

At the end of Page 18 in NISTIR 7563 …

2.7.2 Multi-Storey Frame Buildings

In recent years, the fire performance of large-frame structures has been shown in some instances to be better than the fire resistance of the individual structural elements (Moore and Lennon 1997).  These observations have been supported by extensive computer analyses, including Franssen, Schleich, and Cajot (1995) who showed that, when axial restraint from thermal expansion of the members is included in the analysis of a frame building, the behaviour is different from that of the column and beam analyzed separately.

A large series of full-scale fire tests was carried out between 1994 and 1996 in the Cardington Laboratory of the Building Research Establishment in England.  A full-size eight-storey steel building was constructed with composite reinforced concrete slabs on exposed metal decking, supported on steel beams with no applied fire protection other than a suspended ceiling in some tests.  The steel columns were fire-protected.  A number of fire tests were carried out on parts of one floor of the building, resulting in steel beam temperatures up to 1000 °C, leading to deflections up to 600 mm but no collapse and generally no integrity failures (Martin and Moore 1997). “

Those were Experimental Fire Tests at Cardington, not Real Fires … on ‘Engineered’ Test Constructions, not Real Buildings !!   And … incredibly, for a 2009 document … there is no mention at all of World Trade Center Buildings 1, 2 or 7 !?!   Where did they disappear to, I wonder ?   Too hot to handle ???

Computer Model Verification and Validation (V&V) are very problematic issues within the International Fire Science and Engineering Community.  The expected outcome of a Model V&V Process, however, is a quantified level of agreement between experimental data (and, if available, real data) and model prediction … as well as the predictive accuracy of the model.

Now … please meditate carefully on the following …

” NCSTAR 1A (2008)  Recommendation D   [See also NCSTAR 1 (2005)  Recommendation 5)

NIST recommends that the technical basis for the century-old standard for fire resistance testing of components, assemblies and systems be improved through a national effort.  Necessary guidance also should be developed for extrapolating the results of tested assemblies to prototypical building systems.  A key step in fulfilling this Recommendation is to establish a capability for studying and testing components, assemblies, and systems under realistic fire and load conditions.

Of particular concern is that the Standard Fire Resistance Test does not adequately capture important thermally-induced interactions between structural sub-systems, elements, and connections that are critical to structural integrity.  System-level interactions, especially due to thermal expansion, are not considered in the standard test method since columns, girders, and floor sub-assemblies are tested separately.  Also, the performance of connections under both gravity and thermal effects is not considered.  The United States currently does not have the capability for studying and testing these important fire-induced phenomena critical to structural safety.

Relevance to WTC 7:  The floor systems failed in WTC 7 at shorter fire exposure times than the specified fire rating (two hours) and at lower temperatures because thermal effects within the structural system, especially thermal expansion, were not considered in setting the endpoint criteria when using the ASTM E 110 or equivalent testing standard.  The structural breakdowns that led to the initiating event, and the eventual collapse of WTC 7, occurred at temperatures that were hundreds of degrees below the criteria that determine structural fire resistance ratings. “

The design approach outlined in NISTIR 7563 is not only very flawed … it lacks any validity … because very relevant and important real fire data has been totally ignored.  The Cardington Experimental Fires were not all that they seemed.

.

c)  Current ISO TC92 International Case Study Comparison

Structural Fire Engineering Design of an Airport Terminal Building serving the Capital City of a large country (which shall remain nameless) … constructed using Portal Steel Frames …

My first concern is that the Structural Fire Engineering Design has been undertaken in isolation from other aspects of the Building’s Fire Engineering Design.

On Page 3 of the Case Study Report …

4.2 Objectives & Functional Requirements for Fire Safety of Structures

The fire safety objectives of the airport terminal emphasize the safety of life, conservation of property, continuity of operations and protection of the environment. “

Should these not be the Project-Specific Fire Engineering Design Objectives ?   Since when, for example, is ‘continuity of operations’ a concern in building codes ??

On Page 7 of the Case Study Report …

5.3  Identify Objectives, Functional Requirements & Performance Criteria for Fire Safety of Structure

The Fire Safety Objective of the Steel Structure:  There should be no serious damage to the structure or successive collapse in case of fire.

The Functional Requirements are defined as the followings:

(1)  Prevent or limit the structural failure in case of fire so as to prevent the fire from spreading within the compartment or to the adjacent fire compartment or the adjacent buildings (to prevent fire spread) ;

(2)  Prevent or limit the partial structural failure in case of fire so as to protect the life safety of the occupants and firefighters (to protect life safety) ;

(3)  Prevent or limit the structural deformation or collapse so as not to increase the cost or difficulties of the after-fire restoration (to reduce reconstruction cost).

One of the following Performance Requirements shall be met:

(1)  The load-bearing capacity of the structure (Rd) shall not be less than the combined effect (Sm) within the required time, that is Rd ≥ Sm.  (The maximum permitted deflection for the steel beam shall not be larger than L/400, and the maximum stress of the structure under fire conditions shall not be larger than fyT) ;   or

(2)  The fire resistance rating of the steel structure (td) shall not be less than the required fire resistance rating (tm), that is, td ≥ tm ;   or

(3)  Td – the critical internal temperature of the steel structure at its ultimate state shall not be less than Tm (the maximum temperature of the structure within required fire resistance time duration), that is Td ≥ Tm.  (300 ℃) “

Once again … we see an emphasis on critical temperature, beam deflection (only), and material strength.  L/400 is an impressive Fire Serviceability Limit State … a different world from L/20 or L/30 … but what about other important types of steel structural member deformation, e.g. thermal expansion and distortion ??

Furthermore … if there is a major fire in the area under the lower roof (see Section above) … because of structural continuity, any serious impact on the small frame will also have an impact on the large frame.  For Structural Fire Engineering reasons … would it not be wiser to break the structural continuity … and have the small and large portal frames act independently ?

It is proposed that the Portal Frames will NOT be fully fire protected … just the columns, up to a height of 8 metres only.  If ‘conservation of property’ and ‘continuity of operations’ are important fire engineering design objectives in this project … why isn’t all of the steel being fully protected ???   What would be the additional cost, as a percentage of the total project cost ?

What exactly is infallible about current Design Fires and Design Fire Scenarios ???   Not much.  And in the case of this particular building, should a ‘maximum credible fire scenario’ be at least considered ?

And … what is the fire protection material, product or system being used to protect the Portal Frames ?   Will it be applied, fixed or installed correctly ?   What is its durability ?   Will it be able to resist mechanical damage during the construction process … and afterwards, during the fire event ?   What is the reliability of this form of fire protection measure ??

So many questions …

Accessibility-for-All … New Context … Same Old Problems !

2012-04-21:  The context for considering and properly implementing Accessibility-for-All has changed … changed utterly … but some old problems persist, and stubbornly remain …

NEW INTERNATIONAL CONTEXT

     A.  At the time of writing, the United Nations Convention on the Rights of Persons with Disabilities (UN CRPD) has been ratified by 111 Countries and the European Union.

Concerning Accessibility of the Built Environment … UN CRPD Preamble Paragraph (g), and Articles 9 – 11 – 12 are the most immediately relevant.  These texts can be easily found elsewhere on this BLOG … please use the ‘search’ facility at the top, right-hand corner of the WebPage.

With the innovative, and internationally accepted, understanding of ‘Accessibility’ – as distinct from ‘Access’ – contained in ISO 21542 : 2011 … the concept meaning: approach and entry to a building, circulation within and use of all the building’s facilities, egress from and removal from the building’s vicinity during normal circumstances, or evacuation in the event of an emergency and movement – via a safe and accessible route – to a place of safety which is remote from the building … it is now possible to deal with Fire Evacuation of Buildings through Article 9 (Accessibility) of the UN CRPD, where it is more in scale … more at home, so to speak … rather than through Article 11 (Situations of Risk & Humanitarian Emergencies), which had to be the case before.

     B.  ISO 21542: ‘Building Construction – Accessibility & Usability of the Built Environment’ … is the important new International Standard mentioned above.  It was published in December 2011.

Ireland has no National Standard (or Code of Practice) on Accessibility.  So, in the absence of an appropriate Harmonized European Standard, ISO 21542 must take precedence over the National Standards of any other European Union Member State.

Here, however, there is a very large fly in the ointment … the guidance text in the 2010 Technical Guidance Document M has been ‘lifted’, almost en masse, from a British National Standard on ‘Access’ … not ‘Accessibility’.  And this flawed process has imported some serious errors into Irish Accessibility Design and Construction Practice … despite my warnings to the relevant authorities.  Please refer back to this post , dated 2009-06-14.

Scope of ISO 21542 : 2011

ISO 21542:2011 specifies a range of requirements and recommendations for many of the elements of construction, assemblies, components and fittings which comprise the built environment.  These requirements relate to the constructional aspects of access to buildings, to circulation within buildings, to egress from buildings in the normal course of events and evacuation in the event of an emergency.  It also deals with aspects of accessibility management in buildings.

ISO 21542:2011  contains provisions with respect to features in the external environment directly concerned with access to a building or group of buildings from the edge of the relevant site boundary or between such groups of buildings within a common site.  It does not deal with those elements of the external environment, such as public open spaces, whose function is self-contained and unrelated to the use of one specific building, nor does it deal with single family dwellings, other than those circulation spaces and fittings that are common to two or more such dwellings.

     C.  Of direct commercial interest within the European Union (and in any countries outside the EU who wish to trade with the EU and the European Economic Area) … Accessibility-Related Construction Products are now included in the framework of the (relatively) new European Union Regulation No.305/2011 of the European Parliament and of the Council, of 9 March 2011, laying down Harmonized Conditions for the Marketing of Construction Products and Repealing Council Directive 89/106/EEC.  [The old EU Directive 89/106/EEC has been repealed … it is finished, it is gone, it is no more !   There will, however, be a suitable transition period from old to new.]

Construction Product (EU Reg.305/2011)  means any product or kit which is produced and placed on the market for incorporation in a permanent manner in construction works or parts thereof and the performance of which has an effect on the performance of the construction works with respect to the basic requirements for construction works.

Construction Works (EU Reg.305/2011)  means buildings and civil engineering works.

Basic Requirement for Construction Works No. 4  in Annex I of the new EU Regulation 305/2011, states the following …

Safety and Accessibility in Use

The construction works must be designed and built in such a way that they do not present unacceptable risks of accidents or damage in service or in operation such as slipping, falling, collision, burns, electrocution, injury from explosion and burglaries.  In particular, construction works must be designed and built taking into consideration accessibility and use for disabled persons.

This is a suitable location for ‘Accessibility’ in Annex I … intimately connected to ‘Safety in Use’.  However, there is one potential drawback.  Specifying the level of safety in an EU Member State is the sole responsibility of the Authorities Having Jurisdiction (AHJ’s) in that Member State.

An Accessible Building is a Safer Building … but a Safe Building is not necessarily ‘Accessible’.  ‘Accessibility’ is a completely different concept to ‘Safety’.  EU Member States have no basis in EU Law … no justification whatever … for arbitrarily deciding on which level of ‘Accessibility’ is appropriate within their territories !

.

SAME OLD PROBLEMS

With all of this New International Context on Accessibility finally in place … I continue to encounter the same old problems …

     1.  Bad Product Design

An enormous quantity of cheap, atrociously designed … you could almost use the word ‘ugly’ … Accessibility-Related Construction Products are imported every year into Ireland, from Britain.  This is one good reason, although not a very satisfactory reason, why architects hate ‘accessibility’ in buildings.  Building users notice fittings and fixtures … and if the fittings and fixtures are ugly … the building is ugly !   But occupational therapists, for example, are also specifying these types of products every day of the week here.

This has got to stop.  Proper attention must be paid to Good Design of Accessibility-Related Construction Products.  An Accessible Building does not have to look like a Hospital Ward !   And Good Design does not have to mean ‘expensive’ !!

I have seen many well designed Accessibility-Related Construction Products, available in the EU marketplace, which have been manufactured in countries such as France, Germany, Italy, and China.

Why can we not access these products in Ireland ??

     2.  No Product Approval

The National Building Regulations/Codes of EU Member States … and all EU Safety at Work legislation … demand that building products and systems must be properly shown to be ‘fit for their intended use in the location of use’.  End of story … very simple !   Regrettably, few people take any notice of this legal requirement.

Late last year, however, I encountered a Chinese Company which manufactured some nicely designed Accessibility-Related Construction Products.  I suggested to one of their sales personnel that, in order to place their products on the market anywhere in the European Union (or the European Economic Area) … there was an urgent need to update their existing ‘CE Mark’ Product Approval Documentation.  When I checked more closely, this Documentation was dubious.  I then suggested that they should place a correct, up-to-date and relevant CE Mark on their construction products … as a matter of priority.  And I received the following reply …

” i’d like to suggest that maybe you can pay for the cost to do this CE, and after you place orders in our factory, we promise return that back to you, and if you like, maybe you can act as our agency in Ireland, will you ? “

[ The sum of money being discussed here was €1,000.]

This proposal was off-the-wall, as we say here in Ireland.  But, I found it impossible to get annoyed … because this strange and weird understanding of the CE Mark, particularly in relation to Accessibility-Related Construction Products, is rife among European Manufacturers also … and European Notified Bodies.  How crazy is that ?

Perhaps my most unusual experience, back in the mid-1990’s, was having to explain to a Manager in a TÜV Laboratory, in Germany, that a Full Test Report must be issued to a Test Sponsor … after the test(s) has/have been completed.  This task required two to three hours of heated discussion !

And … in the absence of any reference to ‘Accessibility’ in the now repealed EU Directive 89/106/EEC … I have encountered some European Manufacturers of Accessibility-Related Construction Products … who, being fully aware of the value of a CE Mark, have used the backdoor method of the EU Medical Devices Directive in order to obtain a CE Mark.  And these were definitely not medical devices !

There is no effective control over the CE Marking of Construction Products within the European Union.  This is no reason to ignore the system … or to abuse the system.

However … if many more people paid attention to the legal requirement, and necessity, of Proper Product Approval and the CE Marking of Accessibility-Related Construction Products … and the professional duty and responsibility to check that compliance/conformity is properly shown … we would have a more Accessible and much Safer Built Environment !!!
