2012-01-22:  SOME PRELIMINARY COMMENTS …

  1.     Keeping my ear closely to the ground … I hear you wondering: “So … how did the fires actually start in World Trade Center Building 7 ?”

Extracts from the Executive Summary (pages xxxi – xxxv) – 2008 NIST NCSTAR 1A …

[ Refer back to the WTC 1 & 2 Collapse Damage Plan in the previous post.]

The fires in WTC Building 7 were ignited as a result of the impact of debris from the collapse of WTC Tower 1, which was approximately 110 metres to the south.  The debris also caused some structural damage to the south-west perimeter of WTC 7.  The fires were ignited on at least 10 floors;  however, only the fires on Floors 7 to 9 and 11 to 13 grew and lasted until the time of building collapse.  These uncontrolled fires had characteristics similar to those that have occurred previously in tall buildings.  Their growth and spread were consistent with ordinary building content fires.  Had a water supply for the automatic sprinkler system been available and had the sprinkler system operated as designed, it is likely that the fires in WTC 7 would have been controlled, and the collapse prevented.  However, the collapse of WTC 7 highlights the importance of designing fire resisting structures for situations where sprinklers are not present, do not function (e.g. due to disconnected or impaired water supply), or are overwhelmed.

and …

There were no serious injuries or fatalities, because the estimated 4,000 occupants of WTC 7 reacted to the airplane impacts on the two WTC Towers and began evacuating before there was significant damage to WTC 7.  The occupants were able to use both the elevators and the stairs, which were as yet not damaged, obstructed, or smoke-filled.  Evacuation of the building took just over an hour.  The potential for injuries to people leaving the building was mitigated by building management personnel holding the occupants in the lobby until they identified an exit path that was safe from the debris falling from WTC Tower 1.  The decisions not to continue evaluating the building and not to fight the fires were made hours before the building collapsed, so no emergency responders were in or near the building when the collapse occurred.

and …

The design of WTC 7 was generally consistent with the New York City Building Code of 1968 (NYCBC), with which, by policy, it was to comply.  The installed thickness of the thermal insulation on the floor beams was below that required for unsprinklered or sprinklered buildings, but it is unlikely that the collapse of WTC 7 could have been prevented even if the thickness had been consistent with building code requirements.  The stairwells were narrower than those required by the NYCBC, but, combined with the elevators, were adequate for a timely evacuation on 11 September 2001, since the number of building occupants was only about half that expected during normal business hours.

The collapse of WTC 7 could not have been prevented without controlling the fires before most of the combustible building contents were consumed.  There were two sources of water (gravity-fed overhead tanks and the city water main) for the standpipe and automatic sprinkler systems serving Floor 21 and above, and some of the early fires on those upper floors might have actually been controlled in this manner.  However, consistent with the NYCBC, both the primary and back-up source of water for the sprinkler system in the lower 20 floors of WTC 7 was the city water main.  Since the collapses of the WTC Towers had damaged the water main, there was no water available (such as the gravity-fed overhead tanks that supplied water to Floor 21 and above) to control those fires that eventually led to the building collapse.

  2.     On a separate subject and quite by chance … a few days ago, I was invited to review a technical paper for a reputable international fire engineering journal (which shall remain nameless).  The paper was discussing a certain aspect of steel column critical temperatures.  After three days, I replied to the journal’s editor as follows …

2012-01-18.

Most regrettably, I must decline your invitation to review Paper XYZ.

The ‘critical temperature’ approach to the fire engineering design of steel-framed structures is deeply flawed … and obsolete.

C. J. Walsh, FireOx International – Ireland, Italy & Turkey.

The ‘critical temperature’ approach is antiquated … and this nonsense has got to stop !   NOW … would be the best time !!

.

  3.     In the last post, I wrote …

Structural Fire Engineering is concerned with those aspects of fire engineering which relate to structural design for fire, and the complex architectural interaction between a building’s structure and fabric, i.e. non-structure, under conditions of fire and its immediate aftermath.

Indeed !   But, more needs to be added …

I hope it is becoming clearer now that Structural Fire Engineering is not just ambient structural engineering with a few extra ‘bells and whistles’ grafted on … in token consideration of what could happen in fire conditions, i.e. at high temperatures.

[ If, in some jurisdictions, there are no legal requirements to add even those ‘bells and whistles’ … then, typically, even they will be omitted ! ]

This brings me right back to the typical education of Civil/Structural Engineers;  because:  (i) they exit the educational system with little understanding of anything beyond ‘structure’ … in other words, a ‘real’ building, which also comprises ‘fabric’, i.e. non-structure, is a mystery to them;  and (ii) they have difficulty reading architectural drawings … which is why a walk-through inspection of a building, as it is nearing completion, is much preferred over a detailed discussion about drawings at the most appropriate stage, which is well before construction commences … when faults can be readily identified and easily rectified !

In ambient conditions … the architectural interaction between a building’s structure and fabric is difficult, not being entirely static.  Before the surface finishes have been applied, it is immediately obvious when this interaction has been properly ‘designed’, and looks neat and tidy … or, on the vast majority of construction sites, when this interaction is a ‘traffic accident’, and the results are desperately ugly … and you know that they can’t apply the surface finishes quickly enough in order to hide everything from view !

In fire conditions … this architectural interaction between building fabric and structure is complex, certainly very dynamic … and fluid !

It would be more appropriate to think of Structural Fire Engineering as ‘Design in the Hot Form’ … which is a completely different mindset.

It is essential, therefore, that Fire Engineers understand ‘real’ buildings … most importantly, the ‘design’ of real buildings … and, that they know which end is ‘up’ on a real construction site !!   See NIST WTC 7 Recommendation L below.

.

  4.     Since the collapse of WTC Building 7 on 11 September 2001, it has been generally assumed that Fire-Induced Progressive Collapse is a large-scale, macro-phenomenon only.  But, believe it or not, this phenomenon has also been observed at micro-level in small building types.

In fact … Progressive Collapse was already receiving sporadic attention, in Ireland, as far back as the 1980’s …

  • As organizer of the 1987 Dublin International Fire Conference: ‘Fire, Access & Safety in Residential Buildings’, I requested that the following Paper be presented … ‘Design against Progressive Collapse in Fire’ … by Dr. Willie Crowe, who was Head of Construction Technology, in the old Institute for Industrial Research & Standards (IIRS) in Ireland.  He later became Manager of the Irish Agrément Board (IAB).  Those were the days … and Willie really knew his stuff !

Mr. Noel C. Manning, of FireBar in Ireland (www.firebar.ie),  and I both contributed to the development of his Paper.

And now is as good a time as any to give full credit to Noel Manning for his innovative approach to Structural Fire Engineering back in the early 1980’s.  He’s a ‘hard man’ … a term that we use for some special people in Ireland !

Link to the Dublin International Fire Conferences, and a copy of this Paper … www.fireox-international.eu/fire/dublinfire.htm 

  • For approximately 12 years from the mid-1980’s, I was a Member of the National Masonry Panel – the National Standards Authority of Ireland (NSAI) Masonry Standards Advisory Committee.  A small, but substantial, text on Fire-Induced Progressive Collapse in Buildings was included, by me, in the following standard … Irish Standard 325: Code of Practice for Use in Masonry – Part 2: Masonry Construction (1995).  Appendix A – Determination of Movement in Masonry.  A.3 – Thermal Movement.  Once again … those were the days … when I was the only architect in a sea of engineers !!   Not a pretty experience.

.

  5.     What next ?   A final draft of the International CIB W14 Research WG IV Reflection Document on Fire-Induced Progressive Collapse will be completed in time for circulation to all CIB W14 members before the end of March 2012 … well in time for the next CIB W14 Meetings in Greece, near the end of April 2012.

2008 NIST WTC 7 RECOMMENDATIONS  (Final Report NCSTAR 1A)

5.1.3     GROUP 3.  New Methods for Fire Resisting Design of Structures

The procedures and practices used in the fire resisting design of structures should be enhanced by requiring an objective that uncontrolled fires result in burnout without partial or global (total) collapse.  Performance-based methods are an alternative to prescriptive design methods.  This effort should include the development and evaluation of new fire resisting coating materials and technologies, and evaluation of the fire performance of conventional and high-performance structural materials.

NIST WTC 7 Recommendation F  (NCSTAR 1  Recommendation 8).

NIST recommends that the fire resistance of structures be enhanced by requiring a performance objective that uncontrolled building fires result in burnout without partial or global (total) collapse.  Such a provision should recognize that sprinklers could be compromised, non-operational, or non-existent.  Current methods for determining the fire resistance of structural assemblies do not explicitly specify a performance objective.  The rating resulting from current test methods indicates that the assembly (component or sub-system) continued to support its superimposed load (simulating a maximum load condition) during the test exposure without collapse.  Model Building Codes:  This Recommendation should be included in the national model building codes as an objective, and adopted as an integral pert of the fire resistance design for structures.  The issue of non-operational sprinklers could be addressed using the existing concept of Design Scenario 8 of NFPA 5000, where such compromise is assumed and the result is required to be acceptable to the Authority Having Jurisdiction (AHJ).  Affected Standards:  ASCE-7, AISC Specifications, ACI 318, and ASCE/SFPE 29.

Relevance to WTC 7:  Large, uncontrolled fires led to failure of a critical column and consequently the complete collapse of WTC 7.  In the region of the collapse initiation (i.e. on the east side of Floor 13), the fire had consumed virtually all of the combustible building contents, yet collapse was not prevented.

.

NIST WTC 7 Recommendation G  (NCSTAR 1  Recommendation 9).

NIST recommends the development of:  (1) performance-based standards and code provisions, as an alternative to current prescriptive design methods, to enable the design and retrofit of structures to resist real building fire conditions, including their ability to achieve the performance objective of burnout without structural or local fire collapse;  and (2) the tools, guidelines, and test methods necessary to evaluate the fire performance of the structure as a whole system.  Standards development organizations, including the American Institute of Steel Construction, have already begun developing performance-based provisions to consider the effects of fire in structural design.

a.     Standard methodology, supported by performance criteria, analytical design tools, and practical design guidance;  related building standards and codes for fire resistance design and retrofit of structures, working through the consensus process for nationwide adoption;  comprehensive design rules and guidelines;  methodology for evaluating thermo-structural performance of structures;  and computational models and analysis procedures for use in routine design practice.

b.     Standard methodology for specifying multi-compartment, multi-floor fire scenarios for use in the design and analysis of structures to resist fires, accounting for building-specific conditions such as geometry, compartmentation, fuel load (e.g. building contents and any flammable fuels such as oil and gas), fire spread, and ventilation;  and methodology for rating the fire resistance of structural systems and barriers under realistic design-basis fire scenarios.

c.     Publicly available computational software to predict the effects of fires in buildings – developed, validated, and maintained through a national effort – for use in the design of fire protection systems and the analysis of building response to fires.  Improvements should include the fire behaviour and contribution of real combustibles;  the performance of openings, including door openings and window breakage, that controls the amount of oxygen available to support the growth and spread of fires and whether the fire is fuel-controlled or ventilation-controlled;  the floor-to-floor flame spread;  the temperature rise in both insulated and un-insulated structural members and fire barriers;  and the structural response of components, sub-systems, and the total building system due to the fire.

d.     Temperature-dependent thermal and mechanical property data for conventional and innovative construction materials.

e.     New test methods, together with associated conformance assessment criteria, to support the performance-based methods for fire resistance design and retrofit of structures.  The performance objective of burnout without collapse will require the development of standard fire exposures that differ from those currently used.

There is a critical gap in knowledge about how structures perform in real fires, particularly concerning: the effects of fire on the entire structural system (including thermal expansion effects at lower temperatures);  interaction between the sub-systems, elements, and connections;  and scaling of fire test results to full-scale structures (especially for structures with long-span floor systems).

Relevance to WTC 7:  A performance-based assessment of the effects of fire on WTC 7, had it considered all of the relevant thermal effects (e.g. thermal expansion effects that occur at lower temperatures), would have identified the vulnerability of the building to fire-induced progressive collapse and allowed alternative designs for the structural system.

.

5.1.4     GROUP 4.  Improved Active Fire Protection

Active fire protection systems (i.e. sprinklers, standpipes/hoses, fire alarms, and smoke management systems) should be enhanced through improvements to the design, performance, reliability, and redundancy of such systems.

NIST WTC 7 Recommendation H  (NCSTAR 1  Recommendation 12).

NIST recommends that the performance, and possibly the redundancy and reliability of active fire protection systems (sprinklers, standpipes/hoses, fire alarms, and smoke management systems), in buildings be enhanced to accommodate the greater risks associated with increasing building height and population, increased use of open spaces, high-risk building activities, fire department response limits, transient fuel loads, and higher threat profile.

Reliability is affected by (a) redundancy, such that when one water supply is out of service (usually for maintenance), the other interconnected water supply can continue to protect the building and its occupants;  (b) automatic operation of water supply systems (not only for starting fire pumps but also for testing and tank replenishment, with appropriate remote alarms to the fire department and local alarms for notifying emergency personnel);  and (c) the use of suitable equipment and techniques to regulate unusual pressure considerations.

Relevance to WTC 7:  No water was available for the automatic suppression systems on the lower 20 storeys of WTC 7, once water from street-level mains was disrupted.  This lack of reliability in the source of the primary and secondary water supplies allowed the growth and spread of fires that ultimately resulted in collapse of the building.

.

5.1.5     GROUP 6.  Improved Emergency Response

Technologies and procedures for emergency response should be improved to enable better access to buildings, response operations, emergency communications, and command and control in large-scale emergencies.

NIST WTC 7 Recommendation I  (NCSTAR 1  Recommendation 24).

NIST recommends the establishment and implementation of codes and protocols for ensuring effective and uninterrupted operation of the command and control system for large-scale building emergencies.

a.     State, local, and federal jurisdictions should implement the National Incident Management System (NIMS).  The jurisdictions should work with the Department of Homeland Security to review, test, evaluate, and implement an effective unified command and control system.  NIMS addresses interagency co-ordination and establishes a response matrix – assigning lead agency responsibilities for different types of emergencies, and functions.  At a minimum, each supporting agency should assign an individual to provide co-ordination with the lead agency at each incident command post.

b.     State, local, and federal emergency operations centres (EOC’s) should be located, designed, built, and operated with security and operational integrity as a key consideration.

c.     Command posts should be established outside the potential collapse footprint of any building which shows evidence of large multi-floor fires or has serious structural damage.  A continuous assessment of building stability and safety should be made in such emergencies to guide ongoing operations and enhance emergency responder safety.  The information necessary to make these assessments should be made available to those assigned responsibility (see related Recommendations 15 and 23 in NIST NCSTAR 1).

d.     An effective command system should be established and operating before a large number of emergency responders and apparatus are dispatched and deployed.  Through training and drills, emergency responders and ambulances should be required to await dispatch requests from the incident command system and not to self-dispatch in large-scale emergencies.

e.     Actions should be taken via training and drills to ensure a co-ordinated and effective emergency response at all levels of the incident command chain by requiring all emergency responders that are given an assignment to immediately adopt and execute the assignment objectives.

f.     Command post information and incident operations data should be managed and broadcast to command and control centres at remote locations so that information is secure and accessible by all personnel needing the information.  Methods should be developed and implemented so that any information that is available at an interior information centre is transmitted to an emergency responder vehicle or command post outside the building.

Relevance to WTC 7:  (1) The New York City Office of Emergency Management (OEM) was located in WTC 7 and was evacuated before key fire ground decisions had to be made.  The location of OEM in WTC 7, which collapsed due to ordinary building fires, contributed to the loss of robust interagency command and control on 11 September 2001.  (2) Due to the collapse of the WTC Towers and the loss of responders and fire control resources, there was an evolving site leadership during the morning and afternoon.  Key decisions (e.g. not to fight the fires in WTC 7 and to turn off power to the Con Edison substation) were reasonable and would not have changed the outcome on 11 September 2001, but were not made promptly.  Under different circumstances (e.g. if WTC 7 had collapsed sooner and firefighters were still evaluating the building condition), the outcome could have been very different.

.

5.1.6     GROUP 7.  Improved Procedures and Practices

The procedures and practices used in the design, construction, maintenance, and operation of buildings should be improved to include encouraging code compliance by non-governmental and quasi-governmental entities, adoption and application of evacuation and sprinkler requirements in codes for existing buildings, and retention and availability of building documents over the life of a building.

NIST WTC 7 Recommendation J  (NCSTAR 1  Recommendation 27).

NIST recommends that building codes incorporate a provision that requires building owners to retain documents, including supporting calculations and test data, related to building design, construction, maintenance, and modifications over the entire life of the building.*  Means should be developed for off-site storage and maintenance of the documents.  In addition, NIST recommends that relevant information be made available in suitably designed hard copy or electronic formats for use by emergency responders.  Such information should be easily accessible by responders during emergencies.

[ * F-12  The availability of inexpensive electronic storage media and tools for creating large searchable databases makes this feasible.]

Relevance to WTC 7:  The efforts required in locating and acquiring drawings, specifications, tenant layouts, and material certifications, and especially shop fabrication drawings, significantly lengthened the investigation into the collapse of WTC 7.

.

NIST WTC 7 Recommendation K  (NCSTAR 1  Recommendation 28).

NIST recommends that the role of the ‘Design Professional in Responsible Charge’* be clarified to ensure that:  (1) all appropriate design professionals (including, e.g. the fire protection engineer) are part of the design team providing the highest standard of care when designing buildings employing innovative or unusual fire safety systems;  and (2) all appropriate design professionals (including, e.g. the structural engineer and the fire protection engineer) are part of the design team providing the highest standard of care when designing the structure to resist fires, in buildings that employ innovative or unusual structural and fire safety systems.

[ * F-13  In projects involving a design team, the ‘Design Professional in Responsible Charge’ – usually the lead architect – ensures that the team members use consistent design data and assumptions, co-ordinates overlapping specifications, and serves as the liaison between the enforcement and reviewing officials and the owner.  This term is defined in the International Building Code (IBC) and in the International Code Council’s Performance Code for Buildings and Facilities (where it is the Principal Design Professional).]

Relevance to WTC 7:  Following typical practice, none of the design professionals in charge of the WTC 7 Project (i.e. architect – structural engineer – fire protection engineer) was assigned the responsibility to explicitly evaluate the fire performance of the structural system.  Holistic consideration of thermal and structural factors during the design or review stage could have identified the potential for the failure and might have prevented the collapse of the building.

.

5.1.7     GROUP 8.  Education and Training

The professional skills of building and fire safety professionals should be upgraded through a national education and training effort for fire protection engineers, structural engineers, and architects.  The skills of building regulatory and fire service personnel should also be upgraded to provide sufficient understanding and the necessary skills to conduct the review, inspection, and approval tasks for which they are responsible.

NIST WTC 7 Recommendation L  (NCSTAR 1  Recommendation 29).

NIST recommends that continuing education curricula be developed, and programmes be implemented for:  (1) training fire protection engineers and architects in structural engineering principles and design;  and (2) training structural engineers, architects, fire protection engineers, and code enforcement officials in modern fire protection principles and technologies, including the fire resisting design of structures;  and (3) training building regulatory and fire service personnel to upgrade their understanding and skills to conduct the review, inspection, and approval tasks for which they are responsible.  The outcome would further the integration of the disciplines in effective fire-safe design of buildings.

Relevance to WTC 7:  Discerning the fire-structure interactions that led to the collapse of WTC 7 required research professionals with expertise in both disciplines.  Assuring the safety of future buildings will require that participants in the design and review processes possess a combined knowledge of fire science, materials science, heat transfer, and structural engineering, and design.

.

NIST WTC 7 Recommendation M  (NCSTAR 1  Recommendation 30).

NIST recommends that academic, professional short-course, and web-based training materials in the use of computational fire dynamics and thermo-structural analysis tools be developed and delivered to strengthen the base of available technical capabilities and human resources.

Relevance to WTC 7:  NIST stretched the state-of-the-art in the computational tools needed to reconstruct a fire-induced progressive collapse.  This enabled identification of the critical processes that led to that collapse.  Making these expanded tools and derivative, validated, and simplified modelling approaches usable by practitioners could prevent future disasters.

  1.     There were 2 Important Reasons for undertaking this Series of Posts …

(a)       The General Public, and particularly Client Organizations, should be facilitated in directly accessing the core content of the 2005 NIST WTC Recommendations.  Up to now, many people have found this to be a daunting task.  More importantly, I also wanted to clearly show that implementation of the Recommendations is still proceeding far too slowly … and that today, many significant aspects of these Recommendations remain unimplemented.  Furthermore, in the case of some recent key national standards, e.g. British Standard BS 9999, which was published in 2008 … the NIST Recommendations were entirely ignored.

As a golden rule … National Building Codes/Regulations and National Standards … cannot, should not, and must not … be applied without informed thought and many questions, on the part of a building designer !

(b)       With the benefit of hindsight, and our practical experience in FireOx International … I also wanted to add a necessary 2011 Technical Commentary to the NIST Recommendations … highlighting some of the radical implications, and some of the limitations, of these Recommendations … in the hope of initiating a much-needed and long overdue international discussion on the subject.

” Architecture is the language of a culture.”

” A living building is the information space where life can be found.  Life exists within the space.  The information of space is then the information of life.  Space is the body of the building.  The building is therefore the space, the information, and the life.”

C.Y. Lee & Partners Architects/Planners, Taiwan

[ This is a local dialect of familiar Architectural Language.  However, the new multi-aspect language of Sustainable Design is fast evolving.  In order to perform as an effective and creative member of a Trans-Disciplinary Design & Construction Team … can Fire Engineers quickly learn to communicate on these wavelengths ??   Evidence to date suggests not ! ]

.

  2.     ‘Climate Change’ & ‘Energy Stability’ – Relentless Driving Forces for Sustainable Design !

Not only is Sustainable Fire Engineering inevitable … it must be !   And not at some distant point in the future … but now … yesterday !!   There is such a build-up of pressure on Spatial Planners and Building Designers to respond quickly, creatively, intuitively and appropriately to the relentless driving forces of Climate Change (including climate change mitigation, adaptation, and severe weather resilience) and Energy Stability (including energy efficiency and conservation) … that there is no other option for the International Fire Science and Engineering Community but to adapt.  Adapt and evolve … or become irrelevant !!

And one more interesting thought to digest … ‘Green’ is not the answer.  ‘Green’ looks at only one aspect of Sustainable Human & Social Development … the Environment.  This is a blinkered, short-sighted, simplistic and ill-conceived approach to realizing the complex goal of a Safe and Sustainable Built Environment.  ‘Green’ is ‘Sustainability’ for innocent children !!

  (a)      Organization for Economic Co-Operation & Development (OECD) – 2012’s Environmental Outlook to 2050

Extract from Pre-Release Climate Change Chapter, November 2011 …

‘ Climate change presents a global systemic risk to society.  It threatens the basic elements of life for all people: access to water, food production, health, use of land, and physical and natural capital.  Inadequate attention to climate change could have significant social consequences for human wellbeing, hamper economic growth and heighten the risk of abrupt and large-scale changes to our climatic and ecological systems.  The significant economic damage could equate to a permanent loss in average per capita world consumption of more than 14% (Stern, 2006).  Some poor countries would be likely to suffer particularly severely.  This chapter demonstrates how avoiding these economic, social and environmental costs will require effective policies to shift economies onto low-carbon and climate-resilient growth paths.’

  (b)      U.N. World Meteorological Organization (WMO) Greenhouse Gas Bulletin No.7, November 2011

Executive Summary …

The latest analysis of observations from the WMO Global Atmosphere Watch (GAW) Programme shows that the globally averaged mixing ratios of Carbon Dioxide (CO2), Methane (CH4) and Nitrous Oxide (N2O) reached new highs in 2010, with CO2 at 389.0 parts per million (ppm), CH4 at 1808 parts per billion (ppb) and N2O at 323.2 ppb.  These values are greater than those in pre-industrial times (before 1750) by 39%, 158% and 20%, respectively.  Atmospheric increases of CO2 and N2O from 2009 to 2010 are consistent with recent years, but they are higher than both those observed from 2008 to 2009 and those averaged over the past 10 years.  Atmospheric CH4 continues to increase, consistent with the past three years.  The U.S. National Oceanic & Atmospheric Administration (NOAA) Annual Greenhouse Gas Index shows that from 1990 to 2010 radiative forcing by long-lived Greenhouse Gases (GHG’s) increased by 29%, with CO2 accounting for nearly 80% of this increase.  Radiative forcing of N2O exceeded that of CFC-12, making N2O the third most important long-lived Greenhouse Gas.

  (c)      International Energy Agency (IEA) – World Energy Outlook, November 2011

Extract from Executive Summary …

‘ There are few signs that the urgently needed change in direction in global energy trends is underway.  Although the recovery in the world economy since 2009 has been uneven, and future economic prospects remain uncertain, global primary energy demand rebounded by a remarkable 5% in 2010, pushing CO2 emissions to a new high.  Subsidies that encourage wasteful consumption of fossil fuels jumped to over $400 billion.  The number of people without access to electricity remained unacceptably high at 1.3 Billion, around 20% of the world’s population.  Despite the priority in many countries to increase energy efficiency, global energy intensity worsened for the second straight year.  Against this unpromising background, events such as those at the Fukushima Daiichi Nuclear Power Plant and the turmoil in parts of the Middle East and North Africa (MENA) have cast doubts on the reliability of energy supply, while concerns about sovereign financial integrity have shifted the focus of government attention away from energy policy and limited their means of policy intervention, boding ill for agreed global climate change objectives.’

[ Not just in the case of Tall, Super-Tall and Mega-Tall Buildings … but the many, many Other Building Types in the Built Environment … are Building Designers implementing the 2005 & 2008 NIST WTC Recommendations … without waiting for Building and Fire Codes/Regulations and Standards to be properly revised and updated ??   Evidence to date suggests not ! ]

.

  3.     Separate Dilemmas for Client Organizations and Building Designers …

As discussed earlier in this Series … the Fire Safety Objectives of Building and Fire Codes/Regulations are limited to:

  • The protection of building users/occupants ;   and
  • The protection of property … BUT only insofar as that is relevant to the protection of the users/occupants ;

… because the function of Building and Fire Codes is to protect Society.  Well, that is supposed to be true !   Unfortunately, not all Codes/Regulations are adequate or up-to-date … as we have been observing here in these posts.

Toshiba Elevator & Building Systems Corporation (TELC), Japan.

To Whom It May Concern …

Knowing that your organization was involved in the Taipei 101 Project … we have been examining your WebSite very carefully.  However, some important information was missing from there.

For our International Work … we would like to receive technical information on the Use of Elevators for Fire Evacuation in Buildings … which we understand is actually happening in the Taipei Tower, since it was completed in 2004.

The Universal Design approach must also be integrated into any New Elevators.

Can you help us ?

Mr. Thomas Z. Scarangello P.E. – Chairman & CEO, Thornton Tomasetti Structural Engineers, New York.

Dear Thomas,

Knowing that your organization was involved in the structural design of the Taipei 101 Tower, which was completed in 2004 … and in the on-going design of many other iconic tall, super-tall and mega-tall buildings around the world … we have been examining your Company Brochures and WebSite very carefully.  However, some essential information is missing.

As you are certainly aware … implementation of the 2005 & 2008 National Institute of Standards & Technology (NIST) Recommendations on the Collapse of WTC Buildings 1, 2 & 7, in New York, on 11 September 2001 … is still proceeding at a snail’s pace, i.e. very slowly.  Today, many significant aspects of NIST’s Recommendations remain unimplemented.

For our International Work … we would like to understand how you have responded directly to the NIST Recommendations … and incorporated the necessary additional modifications into your current structural fire engineering designs.

Many thanks for your kind attention.  In anticipation of your prompt and detailed response …

Dear Sirs,

Knowing that your architectural practice designed the Taipei 101 Tower, which was completed in 2004 … and, later, was also involved in the design of other tall and super-tall buildings in Taiwan and China … we have been examining your Company WebSite very carefully.  However, some essential information is missing.

As you are probably aware … implementation of the 2005 & 2008 U.S. National Institute of Standards & Technology (NIST) Recommendations on the Collapse of WTC Buildings 1, 2 & 7, in New York City, on 11 September 2001 … is still proceeding at a snail’s pace, i.e. very slowly.  Today, many significant aspects of NIST’s Recommendations remain unimplemented.

For our International Work … we would like to understand how you have responded directly to the NIST Recommendations … and incorporated the necessary additional modifications into your current architectural designs.

Many thanks for your kind attention.  In anticipation of your prompt and detailed response …

So … how many Clients, or Client Organizations, are aware that to properly protect their interests … even, a significant part of their interests … it is vitally necessary that Project-Specific Fire Engineering Design Objectives be developed which will have a much wider scope ?   The answer is … not many !

How many Architects, Structural Engineers, and Fire Engineers fully explain this to their Clients or Client Organizations ?

And how many Clients/Client Organizations either know that they should ask, or have the balls to ask … their Architect, Structural Engineer and Fire Engineer for this explanation … and furthermore, in the case of any High-Rise Building, Iconic Building, or Building having an Important Function or an Innovative Design … ask the same individuals for some solid reassurance that they have responded directly to the 2005 & 2008 NIST WTC Recommendations … and incorporated the necessary additional modifications into your current designs … whatever current Building and Fire Codes/Regulations do or do not say ??   A big dilemma !

.

A common and very risky dilemma for Building Designers, however, arises in the situation where the Project Developer, i.e. the Client/Client Organization … is the same as the Construction Organization.  The Project Design & Construction Team – as a whole – now has very little power or authority if a conflict arises over technical aspects of the design … or over construction costs.  An even bigger dilemma !!

  5.     Please … Your Comments, Views & Opinions ?!?

The future of  Conventional Fire Engineering ended on the morning of Tuesday, 11 September 2001, in New York City … an engineering discipline constrained by a long heritage deeply embedded in, and manacled to, an outdated and inflexible prescriptive approach to Codes/Regulations and Standards … an approach which is irrational, ignores the ‘real’ needs of the ‘real’ people who use and/or occupy ‘real’ buildings … and, quite frankly, no longer makes any scientific sense !!

On the other hand … having confronted the harsh realities of 9/11 and the Mumbai ‘Hive’ Attacks, and digested the 2005 & 2008 NIST WTC Recommendations … Sustainable Fire Engineering … having a robust empirical basis, being ‘person-centred’, and positively promoting creativity … offers the International Fire Science and Engineering Community a confident journey forward into the future … on many diverse routes !

This IS the only appropriate response to the exciting architectural innovations and fire safety challenges of today’s Built Environment.

BUT … what do you think ?

.

2011-12-04:  SOME PRELIMINARY COMMENTS …

  1.     Such is the pervasively high level of both direct and indirect fire losses, not all of which have yet been identified … that a force of committed firefighters, having sufficient numbers and properly trained and equipped, is a valuable social asset in any community … and one not to be weakened or diluted easily.

  2.     Lack of discipline among firefighters was an issue during the day of 9-11 (11th September 2011) in New York …

In real life or death situations, however, discipline is essential … but competent and efficient command, control and co-ordination … facilitated by reliable systems of communication (human and electronic) … are critical.

And accurate, real time information about what is happening at a building fire incident of whatever scale … i.e. situation awareness … is a tool which propels forward and encourages the effective functioning of both the firefighter and the user/occupant evacuating the building.

  3.     A serious gap, internationally … a deep cavern … in the awareness, training and education of firefighters at all levels … is the issue of ‘disability’ and the varying range of abilities in a typical building user/occupant profile.

It is not fully appreciated by firefighters that certain people may die if placed in a standard fireman’s lift position … or, if shouted and screamed at, many people may have no understanding whatever of the firefighter’s intended meaning … or that, in order for everyone to reach a place of safety, it is necessary for firefighters to ensure that safe, accessible routes from the building (i.e. clear of all obstacles, e.g. fire hose lines) are prepared for, thoroughly, in advance of any fire incident … and actually provided should one occur.

Panic attacks during an emergency do exist !   Standard movement times for people evacuating do not exist !!   And … firefighters may themselves become impaired during a building fire incident !!!

  4.     As for building designers … where do I even start ??   Much could, and should, be done in the design and initial construction of a building to assure firefighter safety.  But … where does any requirement to consider this issue appear in national building codes/regulations ??

I have already discussed this matter in relation to European Union (EU) Regulation 305/2011 on Construction Products, where such a requirement is contained in Basic Requirement for Construction Works 2: ‘Safety in Case of Fire’ (Annex I).

2005 NIST WTC RECOMMENDATIONS

GROUP 6.  Improved Emergency Response

Technologies and procedures for emergency response should be improved to enable better access to buildings, response operations, emergency communications, and command and control in large-scale emergencies.

NIST WTC Recommendation 21.

NIST recommends the installation of fire-protected and structurally hardened elevators to improve emergency response activities in tall buildings by providing timely emergency access to responders and allowing evacuation of mobility-impaired building occupants.  Such elevators should be installed for exclusive use by emergency responders during emergencies.*  In tall buildings, consideration also should be given to installing such elevators for use by all occupants.  NIST has found that the physiological impacts on emergency responders of climbing numerous (e.g. 20 or more) storeys makes it difficult to conduct effective and timely firefighting and rescue operations in building emergencies without functioning elevators.  The use of elevators for these purposes will require additional operating procedures and protocols, as well as a requirement for release of elevator door restrictors by emergency response personnel.

[ * F-44  The access time for emergency responders, in tall building emergencies where elevators are not functioning and only stairways can be used, averages between 1 minute and 2 minutes per floor, which, for example, corresponds to between 1½ and 2 hours (depending on the amount of gear and equipment carried) to reach the 60th floor of a tall building.  Further, the physiological impact on the emergency responders of climbing more than 10 to 12 floors in a tall building makes it difficult for them to immediately begin aggressive firefighting and rescue operations.]

Affected Standards:  ASME A 17, ANSI 117.1, NFPA 70, NFPA 101, NFPA 1221, NFPA 1500, NFPA 1561, NFPA 1620, and NFPA 1710.  Model Building and Fire Codes:  The standards should be adopted in model building and fire codes by mandatory reference to, or incorporation of, the latest edition of the standard.

NIST WTC Recommendation 22.

NIST recommends the installation, inspection, and testing of emergency communications systems, radio communications, and associated operating protocols to ensure that the systems and protocols:  (1) are effective for large-scale emergencies in buildings with challenging radio frequency propagation environments;  and (2) can be used to identify, locate, and track emergency responders within indoor building environments and in the field.  The federal government should co-ordinate its efforts that address this need within the framework provided by the SAFECOM programme of the Department of Homeland Security.

a.     Rigorous procedures, including pre-emergency inspection and testing, should be developed and implemented for ensuring the operation of emergency communications systems and radio communications in tall buildings and other large structures (including tunnels and subways), or at locations where communications are difficult.

b.     Performance requirements should be developed for emergency communications systems and radio communications that are used within buildings or in built-up urban environments, including standards for design, testing, certification, maintenance, and inspection of such systems.

c.     An interoperable architecture for emergency communication networks – and associated operating protocols – should be developed for unit operations within and across agencies in large-scale emergencies.  The overall network architecture should cover local networking at incident sites, dispatching, and area-wide networks, considering: (a) the scale of needed communications in terms of the number of emergency responders using the system in a large-scale emergency and the organizational hierarchy; and (b) challenges associated with radio frequency propagation, especially in buildings; (c) interoperability with existing legacy emergency communications systems (i.e. between conventional two-way systems and newer wireless network systems); and (d) the need to identify, locate, and track emergency responders at an incident site.

Affected Standards:  FCC, SAFECOM, NFPA Standards on Electronic Safety Equipment, NFPA 70, NFPA 297, and NFPA 1221.  Model Building Codes:  The standards should be adopted in model building codes by mandatory reference to, or incorporation of, the latest edition of the standard.

NIST WTC Recommendation 23.

NIST recommends the establishment and implementation of detailed procedures and methods for gathering, processing, and delivering critical information through integration of relevant voice, video, graphical, and written data to enhance the situational awareness of all emergency responders.  An information intelligence sector* should be established to co-ordinate the effort for each incident.

[ * F-45  A group of individuals that is knowledgeable, experienced, and specifically trained in gathering, processing, and delivering information critical for emergency response operations, and is ready for activation in large and/or dangerous events.]

Affected Standards:  National Incident Management System (NIMS), NRP, SAFECOM, FCC, NFPA Standards on Electronic Safety Equipment, NFPA 1221, NFPA 1500, NFPA 1561, NFPA 1620, and NFPA 1710.  Model Building Codes:  The standards should be adopted in model building codes by mandatory reference to, or incorporation of, the latest edition of the standard.

NIST WTC Recommendation 24.

NIST recommends the establishment and implementation of codes and protocols for ensuring effective and uninterrupted operation of the command and control system for large-scale building emergencies.

a.     State, local, and federal jurisdictions should implement the National Incident Management System (NIMS).  The jurisdictions should work with the Department of Homeland Security to review, test, evaluate, and implement an effective unified command and control system.  NIMS addresses interagency co-ordination and establishes a response matrix – assigning lead agency responsibilities for different types of emergencies, and functions.  At a minimum, each supporting agency should assign an individual to provide co-ordination with the lead agency at each incident command post.

b.     State, local, and federal emergency operations centres (EOC’s) should be located, designed, built, and operated with security and operational integrity as a key consideration.

c.     Command posts should be established outside the potential collapse footprint of any building which shows evidence of large multi-floor fires or has serious structural damage.  A continuous assessment of building stability and safety should be made in such emergencies to guide ongoing operations and enhance emergency responder safety.  The information necessary to make these assessments should be made available to those assigned responsibility (see related Recommendations 15 and 23).

d.     An effective command system should be established and operating before a large number of emergency responders and apparatus are dispatched and deployed.  Through training and drills, emergency responders and ambulances should be required to await dispatch requests from the incident command system and not to self-dispatch in large-scale emergencies.

e.     Actions should be taken via training and drills to ensure a co-ordinated and effective emergency response at all levels of the incident command chain by requiring all emergency responders that are given an assignment to immediately adopt and execute the assignment objectives.

f.     Command post information and incident operations data should be managed and broadcast to command and control centres at remote locations so that information is secure and accessible by all personnel needing the information.  Methods should be developed and implemented so that any information that is available at an interior information centre is transmitted to an emergency responder vehicle or command post outside the building.

Affected Standards:  National Incident Management System (NIMS), NRP, SAFECOM, FCC, NFPA Standards on Electronic Safety Equipment, NFPA 1221, NFPA 1500, NFPA 1561, NFPA 1620, and NFPA 1710.  Model Building Codes:  The standards should be adopted in model building codes by mandatory reference to, or incorporation of, the latest edition of the standard.

Corporate Social Responsibility – Updated EU Strategy 2011-14

Posted by CJ Walsh

2011-11-15:  The European Commission, in Brussels, recently published a New European Union Policy Document on Corporate Social Responsibility (CSR) … COM(2011) 681 final – Brussels, 2011-10-25.

To access this document … just go down to the EUR-Lex Link on the right hand side of this Page.

The Updated EU CSR Strategy for 2011-2014  signals an important change of direction … more a re-balancing of emphasis … which enterprises, of all sizes, should immediately be aware of … and whether or not these enterprises are located within Europe … or outside, as far away as China, India, Japan, South Africa, the USA or Brazil, etc.

The Updated CSR Strategy  also confirms how the merging of the different and interrelated aspects of Sustainable Human & Social Development, i.e. social, economic, environmental, institutional, political and legal … is progressing nicely, and gathering some momentum.  We have discussed this issue here many times … and promoted it elsewhere in our work, particularly during the last decade.  How time flies !

[ In this last regard, reference should also be made to the United Nations Development Programme (UNDP) 2011 Human Development Report: ‘Sustainability and Equity – A Better Future for All’, which was launched in Copenhagen on 2 November 2011.]

.

A New Definition for Corporate Social Responsibility (CSR) …

The European Commission puts forward a new definition of CSR as ‘the responsibility of enterprises for their impacts on society’.

Respect for applicable legislation and for collective agreements between social partners are prerequisites for meeting that responsibility.  To fully meet their corporate social responsibility, enterprises should have in place a process to integrate social – environmental – ethical – human rights and consumer concerns into their business operations and core strategy in close collaboration with their stakeholders, with the aim of:

  • maximising the creation of shared value for their owners/shareholders, and for their other stakeholders and society at large ;
  • identifying, preventing and mitigating their possible adverse impacts.

The complexity of that process will depend on factors such as the size of the enterprise and the nature of its operations.  For most small and medium-sized enterprises, especially micro-enterprises, the CSR Process is likely to remain informal and intuitive.

To maximise the creation of shared value, enterprises are encouraged to adopt a long-term, strategic approach to CSR, and to explore the opportunities for developing innovative products, services and business models that contribute to Social Wellbeing and lead to higher quality and more productive jobs.

To identify, prevent and mitigate their possible adverse impacts, large enterprises, and enterprises at particular risk of having such impacts, are encouraged to carry out risk-based due diligence, including through their supply chains.

Certain types of enterprise, such as co-operatives, mutuals, and family-owned businesses, have ownership and governance structures that can be especially conducive to responsible business conduct.

.

The Updated EU CSR Strategy elaborates an Action Agenda for 2011-2014 …

     1.  Improving Company Disclosure of Social and Environmental Information:  the new strategy confirms the European Commission’s intention to bring forward a new legislative proposal on this issue.

     2.  Enhancing Market Reward for CSR:  this means leveraging EU Policies in the fields of consumption, investment and public procurement in order to promote market reward for responsible business conduct.

     3.  Enhancing the Visibility of CSR and Disseminating Good Practices:  this includes the creation of a European award, and the establishment of sector-based platforms for enterprises and stakeholders to make commitments and jointly monitor progress.

     4.  Improving and Tracking Levels of Trust in Business:  the European Commission will launch a public debate on the role and potential of enterprises, and organise surveys on citizen trust in business.

     5.  Better Aligning European and International Approaches to CSR:  the European Commission highlights the following …

  • OECD Guidelines for Multinational Enterprises ;
  • 10 Principles of the UN Global Compact ;
  • UN Guiding Principles on Business and Human Rights ;
  • ILO Tri-Partite Declaration of Principles on Multinational Enterprises and Social Policy ;
  • ISO 26000 Guidance Standard on Social Responsibility.

     6.  Further Integrating CSR into Education, Training and Research:  the European Commission will provide further support for education and training in the field of CSR, and explore opportunities for funding more research.

     7.  Improving Self- and Co-Regulation Processes:  the European Commission proposes to develop a short protocol to guide the development of future self- and co-regulation initiatives.

     8.  Emphasising the Importance of National and Sub-National CSR Policies:  the European Commission invites EU Member States to present or update their own plans for the promotion of CSR by mid 2012.

Personal Ethics – The Heart of Sustainability Implementation !

Posted by CJ Walsh

2011-02-15 …

Regular visitors, here, will have very little doubt about my understanding of Sustainable Human & Social Development … which is an intricate, open, dynamic and continuously evolving concept.  And about my firm conviction that Sustainable Design involves far more than merely substituting the word ‘sustainable’ … for ‘green’, ‘ecological’ or ‘environment-friendly’ … or any number of insipid alternatives which still regularly appear in the popular and/or academic media !   Who, in their right minds, wouldn’t be confused ?!?

‘Sustainability’ is Not … and Cannot … be just another graft onto Conventional Design Practice … whether that be Spatial Planning, Architectural / Engineering / Industrial Design or e-Design !

Sustainable Design & Construction … is the creative and ethical response, in resilient built or wrought (worked) form, to the concept of ‘Sustainable Human & Social Development’.

.

SUSTAINABILITY IMPLEMENTATION

Opinion:  At the Heart of Implementation which is Authentically ‘Sustainable’ … (a colleague of mine is very fond of using that word ‘authentic’) … must lie a Personal Code of Ethics.  By that, I do Not mean … and I am Not referring to … a Professional Code of Conduct … which is mainly about the self-protection and self-preservation of a professional class !

Everyday Reality:  If we examine, for a moment, two interesting examples … Climate Change Mitigation & Adaptation or the 9-11(2001) Collapses of World Trade Center Buildings 1, 2 & 7 in New York … such is the great time-lag between general societal recognition of a critical design challenge … and then, the passing of relevant national legislation which can really only demarcate a minimal threshold of performance … and next, the associated production of standardized design guidelines … and finally, the imposition of effective monitoring and verification procedures … that the only practical approach is to base Sustainability Implementation on a robust Personal Code of Ethics … with an overt emphasis on Continuing Professional Development (CPD).

I hasten to add that this is not how we (society) are currently educating the design disciplines … and this is not how the professional institutes are operating.

.

PERSONAL CODE OF ETHICS

For many years, in my presentations around Europe, the Arab Gulf Region, India and South America … I have been actively promoting the WFEO/FMOI (UNESCO) Model Code of Ethics as a suitable template for use by all of the design-related disciplines.  Recently, however, our Organization … Sustainable Design International … has undertaken a major review of this 2001 Code, and produced a 2011 Update which tackles the following matters of major concern in our world of shameful waste and social inequality:

  • Sustainable Human & Social Development ;
  • Climate Change Mitigation & Adaptation ;
  • Strengthening the Voice of Vulnerable Social Groups, particularly People with Activity Limitations.

.

WFEO/FMOI (UNESCO)

World Federation of Engineering Organizations – Fédération Mondiale des Organisations d’Ingénieurs

MODEL CODE OF ETHICS

Since 1990, WFEO/FMOI has worked to prepare a Code of Ethics under the supervision of Donald Laplante (Canada), David Thom (New Zealand), Bud Carroll (USA), and others.  It is expected that the Model Code, adopted in 2001, will be used to define and support the creation of codes in member and related professional institutions.  This version of the Model Code was updated by C.J. Walsh (Ireland) in 2011.

IV.           CONCLUSION

INTERPRETATION OF THE CODE

  • Fairness and Integrity in the Workplace
  • Professional Accountability & Leadership

.

WFEO/FMOI MODEL CODE OF ETHICS

I.  BROAD PRINCIPLES

Ethics is generally understood as the discipline or field of study dealing with moral duty or obligation.  This typically gives rise to a set of governing principles or values, which in turn are used to judge the appropriateness of a particular conduct or behaviour.  These principles are usually presented either as broad guiding principles of an idealistic or inspirational nature or, alternatively, as a detailed and specific set of rules couched in legalistic or imperative terms to make them more enforceable.  Professions which have been given the privilege and responsibility of self regulation, including the engineering professions, have tended to opt for the first alternative, espousing sets of underlying principles as codes of professional ethics which form the basis and framework for responsible professional practice.  Arising from this context, professional codes of ethics have sometimes been incorrectly interpreted as a set of ‘rules’ of conduct intended for passive observance.  A more appropriate use by practicing professionals is to interpret the essence of the underlying principles within their daily decision-making situations in a dynamic manner, responsive to the needs of the situation.  As a consequence, a code of professional ethics is more than a minimum standard of conduct ;  rather, it is a set of principles which should guide professionals in their daily work.

In summary, the Model Code presented herein elaborates the expectations of engineers and society in discriminating engineers’ professional responsibilities.  The Code is based on broad principles of truth, honesty and trustworthiness, respect for human life and social wellbeing, fairness, openness, competence and accountability.  Some of these broader ethical principles or issues deemed more universally applicable are not specifically defined in the Code, although they are understood to be applicable as well.  Only those tenets deemed to be particularly applicable to the practice of professional engineering are specified.  Nevertheless, certain ethical principles or issues not commonly considered to be part of professional ethics should be implicitly accepted to judge the engineer’s professional performance.

Issues regarding protection of the natural environment, climate change mitigation and adaptation, and sustainable development know no geographical boundaries.  The engineers and citizens of all nations should know and respect the ethics of sustainability.  It is desirable, therefore, that engineers in each nation continue to observe the philosophy of the Principles of Sustainable Ethics, as delineated in Section III of this code.

II.  PRACTICE PROVISION ETHICS

Professional engineers shall:

  • hold paramount the safety, health and wellbeing of the public, particularly people with activity limitations, indigenous peoples and other vulnerable groups in society … and the protection of both the natural and the built environments in accordance with the Principles of Sustainable Human & Social Development ;
  • promote health and safety within the workplace ;
  • offer services, advise on or undertake engineering assignments only in areas of their competence, and practice in a careful and diligent manner ;
  • act as faithful agents of their clients or employers, maintain confidentially and disclose conflicts of interest ;
  • keep themselves informed in order to maintain their competence, strive to advance the body of knowledge within which they practice and provide opportunities for the professional development of their subordinates and fellow practitioners ;
  • conduct themselves with fairness, and good faith towards clients, colleagues and others, give credit where it is due and accept, as well as give, honest and fair professional criticism ;
  • be aware of and ensure that clients and employers are made aware of the environmental and socio-economic consequences of actions or projects, and endeavour to interpret engineering issues to the public in an objective and truthful manner ;
  • present clearly to employers and clients the possible consequences of overruling or disregarding engineering decisions or judgment ;
  • report to their association and/or appropriate agencies any illegal or unethical engineering decisions or practices of engineers or others.

III.  ETHICS OF SUSTAINABLE ENGINEERING

Engineers, as they develop any professional activity, shall:

  • try with the best of their ability, courage, enthusiasm and dedication, to obtain a superior technical achievement, which will contribute to and promote a healthy and agreeable surrounding for all people, including indigenous peoples and other vulnerable social groups, in open spaces as well as indoors ;
  • strive to accomplish the beneficial objectives of their work with the lowest possible consumption of raw materials and energy and the lowest production of wastes and any kind of pollution ;
  • discuss in particular the consequences of their proposals and actions, direct or indirect, immediate or long term, upon human health, social equity and the local culture and system of values ;
  • study thoroughly the environment that will be affected, assess all the impacts that might arise in the structure, dynamics and aesthetics of the eco-systems involved, urbanized or natural, as well as in the pertinent socio-economic systems … and select the best alternative for development which is environmentally sound, resilient to climate change and sustainable ;
  • promote a clear understanding of the actions required to restore and, if possible, to improve the environment that may be disturbed, and include them in their proposals ;
  • reject any kind of commitment that involves unfair damages for human surroundings and nature, and aim for the best possible technical, socio-economic, and political solution ;
  • be aware that the principles of eco-system interdependence, biodiversity maintenance, resource recovery and inter-relational harmony form the basis of humankind’s continued existence and that each of these bases poses a threshold of sustainability that should not be exceeded.

IV. CONCLUSION

Always remember that war, greed, misery and ignorance, plus natural disasters and human-induced pollution, climate change and destruction of resources, are the main causes for the progressive impairment of the environment and that engineers, as active members of society, deeply involved in the promotion of development, must use our talent, knowledge and imagination to assist society in removing those evils and improving the quality of life for all people, including indigenous peoples and other vulnerable groups.

.

INTERPRETATION OF THE WFEO/FMOI MODEL CODE

The interpretive articles which follow expand on and discuss some of the more difficult and inter-related components of the Code, especially with regard to the Practice Provisions.  No attempt is made to expand on all clauses of the Code, nor is the elaboration presented on a clause-by-clause basis.  The objective of this approach is to broaden the interpretation, rather than narrow its focus.  The ethics of professional engineering is an integrated whole and cannot be reduced to fixed ‘rules’.  Therefore, the issues and questions arising from the Code are discussed in a general framework, drawing on any and all portions of the Code to demonstrate their inter-relationship and to expand on the basic intent of the Code.

Sustainable Development & Climate Change

Engineers shall strive to enhance the quality, durability and climate change resilience of the Human Environment (including the built, social, economic and virtual environments), and to promote the Principles of Sustainable Human & Social Development.

Engineers shall seek opportunities to work for the enhancement of safety, health, and the social wellbeing of both their local community and the global community through the practice of sustainable development.

Engineers whose recommendations are overruled or ignored on issues of safety, health, social wellbeing, or sustainable development, shall inform their contractor or employer of the possible consequences.

Protection of the Public, and the Natural Environment

Professional Engineers shall hold paramount the safety, health and wellbeing of the public, including people with activity limitations, indigenous peoples and other vulnerable groups in society … and protection of the natural environment.  This obligation to the safety, health and wellbeing of the general public, which includes his/her own work environment, is often dependent upon engineering judgments, risk assessments, decisions and practices incorporated into structures, machines, products, processes and devices.  Therefore, engineers must control and ensure that what they are involved with is in conformity with accepted engineering practices, standards and applicable codes, and would be considered safe based on peer adjudication.  This responsibility extends to include all and any situations which an engineer encounters, and includes an obligation to advise the appropriate authority if there is reason to believe that any engineering activity, or its products, processes, etc., do not conform with the above stated conditions.

The meaning of paramount in this basic tenet is that all other requirements of the Code are subordinate, if protection of public safety, the natural environment or other substantive public interests are involved.

Faithful Agent of Clients and Employers

Engineers shall act as faithful agents or trustees of their clients and employers with objectivity, fairness and justice to all parties.  With respect to the handling of confidential or proprietary information, the concept of ownership of the information and protecting that party’s rights is appropriate.  Engineers shall not reveal facts, data or information obtained in a professional capacity without the prior consent of its owner.  The only exception to respecting confidentially and maintaining a trustee’s position is in instances where the public interest or the natural environment is at risk, as discussed in the preceding section ;  but even in these circumstances, the engineer should endeavour to have the client and/or employer appropriately redress the situation, or at least, in the absence of a compelling reason to the contrary, should make every reasonable effort to contact them and explain clearly the potential risks, prior to informing the appropriate authority.

Professional Engineers shall avoid conflict of interest situations with employers and clients but, should such conflict arise, it is the engineer’s responsibility to fully disclose, without delay, the nature of the conflict to the party/parties with whom the conflict exists.  In those circumstances where full disclosure is insufficient, or seen to be insufficient, to protect all parties’ interests, as well as the public, the engineer shall withdraw totally from the issue or use extraordinary means, involving independent parties if possible, to monitor the situation.  For example, it is inappropriate to act simultaneously as agent for both the provider and the recipient of professional services.  If a client’s and an employer’s interests are at odds, the engineer shall attempt to deal fairly with both.  If the conflict of interest is between the intent of a corporate employer and a regulatory standard, the engineer must attempt to reconcile the difference, and if that is unsuccessful, it may become necessary to inform his/her association and the appropriate regulatory agency.

Being a faithful agent or trustee includes the obligation of engaging, or advising to engage, experts or specialists when such services are deemed to be in the client’s or employer’s best interests.  It also means being accurate, objective and truthful in making public statements on behalf of the client or employer when required to do so, while respecting the client’s and employer’s rights of confidentiality and proprietary information.

Being a faithful agent includes not using a previous employer’s or client’s specific privileged or proprietary information and trade practices or process information, without the owner’s knowledge and consent.  However, general technical knowledge, experience and expertise gained by the engineer through involvement with the previous work may be freely used without consent or subsequent undertakings.

Competence & Knowledge

Professional Engineers shall offer services, advise on or undertake engineering assignments only in areas of their competence by virtue of their training and experience.  This includes exercising care and communicating clearly in accepting or interpreting assignments, and in setting expected outcomes.  It also includes the responsibility to obtain the services of an expert if required or, if the knowledge is unknown, to proceed only with full disclosure of the circumstances and, if necessary, of the experimental nature of the activity to all parties involved.  Hence, this requirement is more than simply duty to a standard of care, it also involves acting with honesty and integrity with one’s client or employer, and one’s self.  Professional Engineers have the responsibility to remain abreast of developments and knowledge in their area of expertise, that is, to maintain their own competence.  Should there be a technologically driven or individually motivated shift in the area of technical activity, it is the engineer’s duty to attain and maintain competence in all areas of involvement including being knowledgeable with the technical and legal framework and regulations governing their work.  In effect, it requires a personal commitment to ongoing professional development, continuing education and self-testing.

In addition to maintaining their own competence, Professional Engineers have an obligation to strive to contribute to the advancement of the body of knowledge within which they practice, and to the profession in general.  Moreover, within the framework of the practice of their profession, they are expected to participate in providing opportunities to further the professional development of their colleagues.

This competence requirement of the Code extends to include an obligation to the public, the profession and one’s peers, that opinions on engineering issues are expressed honestly and only in areas of one’s competence.  It applies equally to reporting or advising on professional matters and to issuing public statements.  This requires honesty with one’s self to present issues fairly, accurately and with appropriate qualifiers and disclaimers, and to avoid personal, political and other non-technical biases.  The latter is particularly important for public statements or when involved in a technical forum.

Fairness and Integrity in the Workplace

Honesty, integrity, continuously updated competence, devotion to service and dedication to enhancing the life quality of society are cornerstones of professional responsibility.  Within this framework, engineers shall be objective and truthful and include all known and pertinent information in professional reports, statements and testimony.  They shall accurately and objectively represent their clients, employers, associates and themselves, consistent with their academic experience and professional qualifications.  This tenet is more than ‘not misrepresenting’ ;  it also implies disclosure of all relevant information and issues, especially when serving in an advisory capacity or as an expert witness.  Similarly, fairness, honesty and accuracy in advertising are expected.

If called upon to verify another engineer’s work, there is an obligation to inform (or make every effort to inform) the other engineer, whether the other engineer is still actively involved or not.  In this situation, and in any circumstance, engineers shall give proper recognition and credit where credit is due and accept, as well as give, honest and fair criticism on professional matters, all the while maintaining dignity and respect for everyone involved.

Engineers shall not accept, nor offer covert payment or other considerations for the purpose of securing, or as remuneration for, engineering assignments.  Engineers should prevent their personal or political involvement from influencing or compromising their professional role or responsibility.

Consistent with the Code, and having attempted to remedy any situation within their organization, engineers are obligated to report to their association or other appropriate agency any illegal or unethical engineering decisions by engineers or others.  Care must be taken not to enter into legal arrangements which compromise this obligation.

Professional Accountability & Leadership

Engineers have a duty to practice in a careful and diligent manner, and accept responsibility and be accountable for their actions.  This duty is not limited to design, or its supervision and management, but applies to all areas of practice.  For example, it includes construction supervision and management, preparation of drawings, engineering reports, feasibility studies, sustainability impact assessments, engineering developmental work, etc.

The signing and sealing of engineering documents indicates the taking of responsibility for the work.  This practice is required for all types of engineering endeavour, regardless of where or for whom the work is done, including but not limited to, privately and publicly owned firms, large corporations, and government agencies or departments.  There are no exceptions ;  signing and sealing documents is appropriate whenever engineering principles have been used and public wellbeing may be at risk.

Taking responsibility for engineering activity includes being accountable for one’s own work and, in the case of a senior engineer, accepting responsibility for the work of a team.  The latter implies responsible supervision where the engineer is actually in a position to review, modify and direct the entirety of the engineering work.  This concept requires setting reasonable limits on the extent of activities, and the number of engineers and others, whose work can be supervised by the responsible engineer.  The practice of a ‘symbolic’ responsibility or supervision is the situation where an engineer, say with the title of Chief Engineer, takes full responsibility for all engineering on behalf of a large corporation, utility or governmental agency, even though the engineer may not be aware of many of the engineering activities or decisions being made daily throughout the firm or agency.  The essence of this approach is that the firm is taking the responsibility by default, whether engineering supervision or direction is applied or not.

Engineers have a duty to advise their employer and, if necessary, their clients and even their professional association, in that order, in situations when the overturning of an engineering decision may result in breaching their duty to safeguard the public, including people with activity limitations, indigenous peoples and other vulnerable social groups.  The initial action is to discuss the problem with the supervisor/employer.  If the employer does not adequately respond to the engineer’s concern, then the client must be advised in the case of a consultancy situation, or the most senior officer should be informed in the case of a manufacturing process plant or government agency.  Failing this attempt to rectify the situation, the engineer must advise in confidence his/her professional association of his/her concerns.

In the same order as mentioned above, the engineer must report unethical engineering activity undertaken by other engineers, or by non-engineers.  This extends to include, for example, situations in which senior officials of a firm make ‘executive’ decisions which clearly and substantially alter the engineering aspects of the work, or protection of public wellbeing or the natural environment arising from that work.

Because of developments in technology and the increasing ability of engineering activities to impact on the environment, engineers have an obligation to be mindful of the effect that their decisions will have on the environment and the wellbeing of society, and to report any concerns of this nature in the same manner as previously mentioned.  Further to the above, with the rapid advancement of technology in today’s world and the possible social impacts on large populations of people, engineers must endeavour to foster the public’s understanding of technical issues and the role of Engineering more than ever before.

Sustainable development is the challenge of meeting current human needs for natural resources, industrial products, energy, food, transportation, shelter, and effective waste management while conserving and, if possible enhancing, the Earth’s environmental quality, natural resources, ethical, intellectual, working and affectionate capabilities of people and the socio-economic bases essential for the human needs of future generations.  The proper observance of these principles will considerably help to eradicate world poverty.
