Fire Safety in Buildings – Reliable Design, Supply & Construction

2019-07-31:  A very serious problem in modern buildings (post 1950’s), and in many countries around the world … which can lie dormant and hidden from any and all Surface Inspections … until there is an outbreak of #Fire !

Passive/Active Fire Protection Measures, and Building Management Systems (i.e. any combination of human and smart systems), are never 100% Reliable.  However, Poor Workmanship on Building Sites and Unauthorized Product / System Substitution are reducing this #Reliability to far below the threshold of legal (or any other) ‘acceptability’.

As a result, Fire Evacuation Routes can quickly become full of dense toxic smoke, impairing/incapacitating people trying to evacuate … the integrity of Fire Compartments can very rapidly be compromised, leading to uncontrolled internal fire spread … and Partial Structural Collapse will be a definite probability.

Most in danger and at high risk in ‘real’ building fires are Vulnerable Building Users and #Firefighters !

[ Vulnerable People: Those people – in a community, society or culture – who are most at risk of being physically, psychologically or sociologically wounded, hurt, damaged, injured, or killed … and include, for example, People with Disabilities, Young Children, People with Health Conditions, Frail Older People, Women in Late Pregnancy, Refugees, Migrants, and the Poor. ]

.

‘Building Materials and Workmanship’ Must Be Relentlessly Monitored PRIOR TO AND DURING Construction – Afterwards Is TOO LATE !

.

In these days of #Architects staring at computer screens all day, not being very ‘smart’ in and around actual construction sites … and with Fire Engineering Design Information still merely a #BIM add-on … there are 5 Fundamental Principles of Reliable Building Design, Product Supply and Construction for Fire Safety :

  1. Design of the works must be exercised by an independent, appropriately qualified and experienced architect/engineer/fire engineer, with design competence relating to the fire protection of buildings ;
  1. The Supply of ‘fit for purpose’ fire safety related construction products/systems to the works must be undertaken by reputable organizations with construction competence, particularly in relation to the fire protection of buildings … and all product/system substitution must be pre-authorized ;
  1. Installation/Fitting of fire safety related construction products/systems must be exercised by appropriately qualified and experienced personnel, with construction competence relating to the fire protection of buildings ;
  1. Supervision of the works must be 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, must be carried out to verify that the works are being executed in accordance with the design.

.

Self-Regulation / Self-Monitoring Is NO Regulation / NO Monitoring !!

.

Incomplete / inaccurate information about the number of People, particularly Vulnerable Building Users, still remaining in a Fire Building, and/or the number of Occupants waiting in Areas of Rescue Assistance and Lift/Elevator Lobbies … all resulting from poor Building Management … will greatly increase the Hazards and Risks involved in Firefighter Search and Rescue Operations, and will result in Building Occupant Injuries and Deaths !

.

Mainstream Fire Codes & Standards DO NOT Protect Vulnerable Building Users and Firefighters !!!

Defective Building Materials, Irish Pyrite & Chinese Plasterboard – FUBAR !

2014-07-08:  Why do individuals and institutions wake up to a problem only when extensive damage to property, or horrendous injury to people, has already occurred … and the shit hits the fan … big time ?!?   What way is that to organize a society … or protect its communities ???

The Answer is Simple:  Prevention !  Not Cure … when damage cannot be effectively repaired … some injuries can never be healed … and it becomes very costly to do anything !!

.

In Ireland … Part D of the Second Schedule to the Building Regulations, as amended, states the following …

Materials & Workmanship

Legal Requirement D1:  All works to which these Regulations apply shall be carried out with proper materials and in a workmanlike (i.e. competent) manner.

Definition of ‘Proper Materials’

Proper Materials:  Building/construction materials (or products, systems, assemblies, etc.) which are fit for the use for which they are intended and for the conditions/location in which they are to be used.

Reference European Union (EU) Legislation

EU Regulation No.305/2011 of the European Parliament and of the Council, of 9 March 2011, laying down harmonised conditions for the marketing of construction products and repealing Council Directive 89/106/EEC.

[ N.B. The 1989 European Directive on Construction Products (89/106/EEC) was repealed, in 2011, by Article 65 of EU Regulation No.305/2011. ]

.

THEREFORE …

It is the duty of a Supplier … any Supplier, e.g. manufacturer, distributor, agent, wholesaler, whatever … of building/construction materials to clearly show that they are ‘proper materials’, i.e. they are fit for the use for which they are intended and for the conditions/location in which they are to be used.

Refer to SDI’s Technical Guidance Noteswww.sustainable-design.ie/arch/tgn.htm

AND …

It is the duty of the Design Professional in Responsible Charge of a construction project (whoever he/she may be – architect, engineer, etc., etc.) to demand of a Supplier … additionally and most particularly, where there are any doubts about any relevant aspect of that material’s performance … that he/she/they clearly show that the building/construction materials they are supplying are ‘proper materials’, i.e. they are fit for the use for which they are intended and for the conditions/location in which they are to be used.

SO …

When Pyrite, for example, shows up in the hardcore under a finished concrete floor, or in the blockwork of a completed wall, in an Irish building … we know who has ignored his or her legal/professional duty concerning proper and satisfactory compliance with Legal Requirement D1 … and who is liable.

For bureaucrats and the legal profession, this is the end of the story.

BUT …

At this stage – when building occupants are hurt and extremely annoyed following, perhaps years, of inconvenience and discomfort – it’s too late !   The damage cannot be effectively repaired … and such limited repairs which can, in practical terms, be carried out will be very expensive.

PLAY IT AGAIN, SAM …

In Ireland, have we properly learned any lessons from Priory Hall, Pyrite, or Chinese Plasterboard ?   No !

Could these or similar problems occur AGAIN on an Irish building site ?   Yes !

Because … aided and abetted by the professional institutes … a ‘blind eye’ is being turned to the greatest lesson of all … that self-regulation/self-certification does NOT work !!

.

And Other E.U. Member States ???

The wording in national/local legislation may be slightly different … the language certainly will be different … but the legal intent is the same.

Legal/professional duties are similar.

Self-regulation/self-certification doesn’t work there either !
