Resilience

After Grenfell: Reliable Design, Supply & Construction Essential !

2017-10-10:  After the Grenfell Tower Fire Tragedy in London, on 14 June 2017, the integrity of the English Regulatory and Technical/Building Control Systems is now so compromised that a complete Systems Transformation is immediately required !   Closer to home, here in Ireland … what nobody is daring to say, even our tame media, is that Our Regulatory System is based very closely on the English System.  And Our Technical/Building Control System is purposefully under-resourced … so it is weak and ineffective.

Let there be no confusion … Priory Hall and Longboat Quay, both in Dublin, are just the tip of an enormous iceberg …

So where do we start again ?

Reality – Reliability – Redundancy – Resilience !

With regard to Reliable Fire Engineering Related Design, Supply and Construction … this is how we must proceed …

  1. Design of the works is exercised by an independent, appropriately qualified and experienced architect/engineer/fire engineer, with design competence relating to the fire protection of buildings ;
  1. Supply of fire safety related construction products/systems to the works is undertaken by reputable organizations with construction competence, particularly in relation to the fire protection of buildings ;
  1. Installation/fitting of fire safety related construction products/systems is exercised by appropriately qualified and experienced personnel, with construction competence relating to the fire protection of buildings ;
  1. Supervision of the works is exercised by appropriately qualified and experienced personnel from the principal construction organization ;
  1. Regular inspections, by appropriately qualified and experienced personnel familiar with the design, and independent of both the design and construction organizations, are carried out to verify that the works are being executed in accordance with the design.

Residential Fire Suppression System – Low Pressure Water Mist

2016-06-13:  Further to the Urgent Fire Safety Recommendations in Modern High-Performance Housing (posted on 2016-04-11) … this is what a Residential Fire Suppression System would look like in a Notional Detached House, and what it would cost …

Low Pressure Water Mist Fire Suppression System

Water flow rate = 13.94 litres per nozzle per minute.  Pressurized 300 Litre Water Cylinder, with BurnStop environment-friendly additive, supplies water to the low flow rate, CPVC (Chlorinated Polyvinyl Chloride) pipe network serving 25 Mist Ceiling Heads/Nozzles fixed at pre-determined locations.  See Plans.  Water runtime is 10 minutes, between 2 heads operating simultaneously without any mains water backup.  Installation takes 3 days in total (2 days first fix, plus 1 day second fix and commissioning).

The mains water supply system in Ireland is not reliable.

A water mist system or a sprinkler system ?

Cost for the above Notional Water Mist Installation is €7,340.00 (Euros) / £5,676.00 (British Pounds) – plus VAT.  This price is on the basis as a one-off installation in Ireland.  If a number of properties require installation at the same time, then travel costs are dispersed and the individual price per property is significantly reduced.

In a Terrace of Houses, where there is a Timber-Framed Party Wall between each house ... a Residential Fire Suppression System MUST be installed in ALL houses to be effective in each single property.

Sustainable Human & Social Development – Reloaded !

2014-04-13:  Further to the Post, dated 2013-01-13

There are many essential qualities and features belonging to and representative of a Sustainable Human Environment (including the Social, Built, Virtual and Economic Environments).  As discussed here many times before … Accessibility-for-All is one fundamental attribute, under Social and Legal Aspects of Sustainable Human and Social Development.

Another fundamental attribute … Urban Resilience … is now moving centre stage in the world of International Construction Research & Practice.  WHEN, not if … this concept is fully elaborated and understood, it will have a profound impact on All Tasks, Activities and Types of Performance in the Human Environment … under All Aspects of Sustainable Human and Social Development.

After working for many years on Climate Change, particularly Adaptation … it was quite natural for me to encounter the concept of Resilience.  But the aim of a newly established Core Task Group within CIB (International Council for Research & Innovation in Building & Construction) is to widen out this concept to also include Severe Natural Events (e.g. earthquakes, typhoons, tsunamis), Complex Humanitarian Emergencies, (e.g. regional famines, mass human migrations), Extreme Man-Made Events (e.g. 2001 WTC 9-11 Attack, 2008 Mumbai ‘Hive’ Attacks), and Hybrid Disasters (e.g. 2011 Fukushima Nuclear Incident) … to set down Resilience Benchmarks … and to produce Resilience Performance Indicators.  An imposing challenge !

AND … as Urbanization is proceeding at such a rapid pace in the BRICS Countries (Brazil, Russia, India, China & South Africa) and throughout the rest of the Southern Hemisphere … ‘practical’ and ‘easily assimilated’ trans-disciplinary output from this CIB Task Group is urgently required.  In other words, the work of the Task Group must not be permitted to become an exercise in long drawn out pure academic research … the clear focus must be on ‘real’ implementation … As Soon As Is Practicable !!

.

A New and Updated Groundwork …

.

SUSTAINABLE DESIGN

The ethical design response, in resilient built and/or wrought form, to the concept of Sustainable Human & Social Development.

SUSTAINABLE HUMAN & SOCIAL DEVELOPMENT

Development which meets the responsible needs, i.e. the human and social rights*, of this generation – without stealing the life and living resources from the next seven future generations.

*As defined in the 1948 Universal Declaration of Human Rights … and augmented by UN OHCHR Letter, dated 6 June 2013, on the Post-2015 Development Agenda.

.

The CITY (as Region)

A geographical region, with open and flexible boundaries, consisting of:

(a)              An interwoven, densely constructed core (built environment) ;

(b)              A large resident population of more than 500,000 people (social environment) ;

(c)              A supporting hinterland of lands, waters and other natural resources (cultivated landscape) ;

together functioning as …

(i)                 a complex living system (analogous to, yet different from, other living systems such as ecosystems and organisms) ;     and

(ii)               a synergetic community capable of providing a high level of individual welfare, and social wellbeing for all of its inhabitants.

.

SOCIAL WELLBEING

A general condition – in a community, society or culture – of health, happiness, creativity, responsible fulfilment, and sustainable development.

INDIVIDUAL WELFARE

A person’s general feeling of health, happiness and fulfilment.

HUMAN HEALTH

A state of complete physical, mental and social wellbeing, and not merely the absence of disease or infirmity.     [World Health Organization]

.

SOCIAL ENVIRONMENT

The complex network of real and virtual human interaction – at a communal or larger group level – which operates for reasons of tradition, culture, business, pleasure, information exchange, institutional organization, legal procedure, governance, human betterment, social progress and spiritual enlightenment, etc.

The social environment shapes, binds together, and directs the future development of the built and virtual environments.

BUILT ENVIRONMENT

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

VIRTUAL ENVIRONMENT

A designed environment, electronically generated from within the built environment, which may have the appearance, form, functionality and impact – to the person perceiving and actually experiencing it – of a real, imagined and/or utopian world.

The virtual and built environments continue to merge into a new augmented reality.

ECONOMIC ENVIRONMENT

The intricate web of real and virtual human commercial activity – operating at micro and macro-economic levels – which facilitates, supports, but sometimes hampers or disrupts, human interaction in the social environment.

.

And So To Work !!
