SECURITY & RESILIENCE IN PUBLIC BUILDINGS : HOW MUCH IS ENOUGH? SAFETY OF LIFE =LIFE SAFETY SAFETY OF QUALITY OF LIFE = QUALITY OF LIFE SAFETY LIFE SAFETY QUALITY OF LIFE
“Right now our public spaces are under surveillance from individuals who are trained to look for vulnerability…….. some structures and spaces can actually assist in their appalling ambitions…….. see the responsibility you have got. Until you do we are back to where we started, back to anxiety, back to fear”(Booth 2008) SECURITY CONFLICT WITH ANY ASPECT THAT MAY POSE A CHALLENGE TO SAFETY OF LIFE OR PROPERTY SECURITY PHYSICAL SECURITY MENTAL SECURITY INTERNATIONAL SECURITY INTERNAL SECURITY BUILT ENVIRONMENT QUESTIONS How does one ‘design’ the security in a building? What are the shortcomings of conventional practices of securing buildings as they have been doing for decades? What is the precipitating need for integrating security in architectural design?
DEFINITION: it is the quality of a building to sustain a disaster (natural or manmade) and return to its functionality without loss of lives and property. SECURITY PREVENTION – FEAR FOR CRIMINALS SECURITY FOR MOST TO BE SECURE RESILIENCE QUESTIONS: What are Resilient structures and how is their performance different from conventional structures? What are the elements or measures as per available technology that can be used in architectural design to target resilience? Are they incremental , meaning the more the measures used, the higher the resilience achieved or are there other factors to consider? RESILIENCE INSURANCE - SAFETY FOR ALL PHYSICAL RESILIENCE MENTAL RESILIENCE NATURAL DISASTERS MAN-MADE DISASTERS
SECURITY: • Counter-terrorism literature based overseas • -indicators on the security programming • -need testing with real life applications • No contemporary material from our country and • -nothing relating to architecture • -structural reports and papers • No documentation of approaches of security agencies within India • -no associated codes or guides within • -knowledge exists undocumented • Global debate on the ‘abstract’ aspects of security and its interpretations. LITERATURE SURVEY: FOCUS 1 UNDERSTANDING SECURITY AND RESILIENCE • RESILIENCE • Disaster resilience guidance • -generic and mostly for disaster relief • - no architectural interpretations. • Structural behaviour • - for previously explored threats like seismic, cyclones, floods, fire etc. is abundant • -aspects like blasts, armed attacks and other contemporary threats raw. • No data on costs, budgeting and sustainability aspects of security found yet.
TO BE SECURE • POSSIBLE INDICATORS OF VARYING INDIVIDUAL RESPONSE: • THRESHOLD OF PANIC • FEAR PSYHCHOSIS, INFIRNGMENT OF PRIVACY, PHYSICAL INTRUSION. • CONTEXTUAL ISSUES OF GENDER, AGE, CASTE, SOCIO-ECONOMIC STATUS & RELIGION • SOCIETY, CULTURE, COUNTRY
“…. with it [is] the need to deliver good design that creates a sense of security without a siege mentality. It is important our built environment continues to reflect that we are an open & inclusive society and that in integrating these new requirements our buildings do not convey that we are driven by security measures.” (RIBA 2010, 2) HOW MUCH ? : FOCUS 2 QUALITATIVE QUANTIFICATION QUESTIONS: How do we as Architects quantify the security & resilience quotient of a design at the requirement and completion stages? How much security in a building is just enough – to counter the threats while anything more would border on the ‘BUNKER MENTALITY’ ? How do we achieve the right balance? • PSYCHO-SOCIAL ACTION & REACTION OF SECURITY • IN SPECIFIC CONTEXT OF BUILT ENVIRONMENT • -MAY NOT ALWAYS BE MEASURABLE • -EVER CHANGING TECHNOLOGIES • -COMPLEX MATRIX WITH BUILTSCAPE
“Technically we can design bunkers with fool proof security and best known resilience but can we be ‘secure’ at the cost of space aesthetics and freedom? Austin William of National Building specifications believes: “…it is contributing to the death of architecture because aesthetics are being sacrificed for sake of precautions…. Public buildings are becoming ‘fear of public’ buildings”(Willaims 2007) HOW MUCH PHYSICAL SECURITY ? QUALITATIVE QUANTIFICATION ‘Mental security’- what is the relationship with physical security? Can the same frisking and scanning that may convince me of a well secured premises push another to panic and fear? Is this factor a function of the individual, society or culture? Does CCTv surveillance make me feel ‘looked after’ or ‘looked at’? Why is the security in our part of the world so visible and overt
“Economy supports security and security supports economy.” Meenakshi Lekhi , MP, BJP, (India 2015) HOW MUCH COST IS JUSTIFIED? • MACRO LEVEL: • 3RD WORLD COUNTRY – WORRIES OF HUNGER & POVERTY • FASTEST GROWING ECONOMY • FOREIGN INVESTMENTS TO • FUEL GROWTH • PUMP ECONOMY • GENERATE JOBS • SOLUTION TO HUNGER AND POVERTY • RESILIENT INFRASTRUCTURE REQUIRED FOR SUSTAINABLE GROWTH & ECONOMIC RESILIENCE • MICRO LEVEL: • TO ATTRACT FDI & INVESTOR CONFIDENCE • DEVELOPMENTAL FUNDAMENTAL • SMART CITY PRE-REQUISITE • SMART INVESTMENT & RETURNS • INNATE VULNERABILTIES ADDRESSAL- NATURAL & MANMADE • ENHANCED LIFE SPAN & USER PSYCHE ECONOMIC Are security and resilience really a luxury meant only for rich countries? What are the budgetary implications of security and resilience in buildings? What are the financial or economic gains? What is the net impact of security and resilience in the net lifespan of a built environment being designed? What is the net impact on the overall economy? What is the net impact taking into consideration investor sentiments & economic resilience?
IMPACT OF SECURITY ASPECTS ON GREENNESS: BUILDING MATERIALS CONSTRUCTION TECHNIQUES EQUIPMENT CONSUMPTION PERSONNEL REQUIREMENT CLIMATE CONTROL SECURITY = IMMEDIATE SURVIVAL RESILIENCE = LONGTERM INSURANCE HOW MUCH IS SUSTAINABLE? SUSTAINABILITY What are the energy requirements for security equipment and resilience measures including the embodied energies? Can architecture contribute towards the reduction of the energy consumption or even the equipment or personnel requirement? Is there a chance that heavily secured or resilient structures could actually be climatically more ‘green’? Is it possible that life span enhancement of resilient structures actually enhances their sustainability while reducing the carbon footprint
MAXIMUM HUMAN IMPETUS= MAX LIFE SAFETY & PSYCHE SECURITY. • LARGE NUMBERS, VOLUMES = EXAGGERATION OF CHALLENGE • HIGHEST HTREAT PROFILE & SECUITY NEED • CRITICALITY OF FUNCTION & CONTINUITY • ECONOMIC & INFRASTRUCTURAL REQUIREMENT FOR DEVELOPING NATIONS “Public buildings are designated so mostly on the basis of their occupancy levels which can range from few hundreds in religious places to several thousands in stadia.”(RIBA 2010) PUBLIC BUILDINGS QUESTIONS What all building types are included in Public buildings? Can we categorize buildings based on their requirements for security and resilience inputs? What are the special challenges of making public buildings secure and resilient?
DUE TO PAUCITY OF LITERATURE AVAILABLE FOR INDIAN CONTEXT, OTHER AVENUES OF KNOWLEDGE COLLECTION: • PRIVATE SECURITY CONSULTANTS • SECURITY CONFERENCES AND WORKSHOPS • SECURITY EXPERTS & ADVISORS- DISCUSSIONS & INTERVIEWS. RESEARCH PROGRESS: RESEARCH LAYOUT The green cells above indicate the parts of research which are well advanced while the pink ones indicate the ones still in infancy. The balance chart the way forward . The scope will be followed as per the limitations listed by the research.
How does an architect approach the task of designing-in the security and resilience of a building when taking up a new design problem? What is the methodical approach to coordination with Client, security team and the local context? What are various ways and means to secure buildings? How can we design and construct resilient buildings? RESEARCH QUESTIONS Do the security and resilience measures enhance fear or security? To what extent can buildings and people be secured through architectural design? What other factors influence the efficacy ? What are the financial, environmental and psycho-social costs involved? How do we justify them and decide what is optimum? Can we categorize the measures in terms of their multi-dimensional costs and develop an optimization mechanism for ease of application?
Architecture can integrate all aspects of security and resilience at the conception of a design to create a sustainable ‘built environment’ that makes its occupants truly secure and resilient , physically and mentally at a negligible cost justifiable by the economic gains.

“Frame buildings designed to resist gravity, wind loads and earthquake loads in the normal way have frequently been found to be deficient in 2 respects: • Failure of beam to column connections • Inability to tolerate load reversal.” • (ZeynepKoccaz 2008) STRUCTURAL REACTION : 1.4.4 COLLAPSE LIMIT DESIGN: AVOID OVERALL COLLAPSE THOUGH BUILDING CANNOT FUNCTION ANYMORE FUNCTIONALITY LIMIT DESIGN : CONTINUE FUNCTIONALITY
“Addressing blast & seismic design goals may be achieved….An understanding of the differences between these 2 loading phenomenon, effects on the structure and performance requirements are essential to select and implement the appropriate choices..” (WBDG 2014) SEISMIC VS BLAST “ Progressive collapse is defined as the spread of an initial local failure from element to element, eventually resulting in the collapse of an entire structure or disproportionately large part of it. The initial failure or damage could be from a number of different causes, which might include natural or man-made hazards…” (ASCE 7, WBDG 2014)
“Blast loads are dynamic loads that need to be carefully calculated, just like earthquake and wind loads” (ZeynepKoccaz 2008) • More attention to design and detailing of structural components • Must for exterior bays and lower floors of buildings • Shorten slab lengths and improve the punching shear resistance.” • Appropriate detailing of slab-column interface. • Bottom reinforcement in slabs continuous through column • Continuously tied reinforcements in both directions • Anchorage of reinforcement at edge of slab • Beam to beam connections • Beam to column connections. • Potential for direct lateral loading on face of columns • Adequate ductility and strength. • Encasing lower floor columns in steel jackets or steel belts or CFRP • Embed steel column within perimeter concrete columns or walls • For smaller loads columns and walls with spiral reinforcements. • Possibility of uplift • Columns designed for transient tensile forces. • Progressive collapse analysis • Hardening- • Several shear walls -beneficial for seismic design also. • Central shear wall with a peripheral movement resisting frame.” • (Jomyn.d.)
