COSTS OF DISASTERS

Kobe earthquake registered a record damage of

US$ 190 Billion.

Only one person died (that too of heart attack)

in the earthquake at Seattle in Feb. 2001 whereas in the Gujarat earthquake of January 2001 of the same intensity 13,500 died and

ver 0.8 million houses were damaged partly
r fully – due to strong pre-disaster mitigation

efforts in Seattle – a clear pointer for effective Building Code Enforcement.

The socio-economic cost of such disasters are

much higher and difficult to estimate and have long-term repercussions on societies, irrespective of the degree of development of the countries.

EMERGING NEED FOR PARADIGM SHIFT IN FOCUS

SLIDE 5

PROMOTING SAFER BUILDINGS/CONSTRUCTION

To ensure massive financial resource investments for housing and other public asset buildings and infrastructure are safe, strong, durable and perform well during their life cycle you need to protect against:

Floods Cyclones/ Typhoons Earthquakes Land slides Sea erosion/Tsunamis

SLIDE 6

PROMOTING SAFER BUILDING CONSTRUCTION

Three critical elements for action areas to promote safer building construction are in creating: Awareness

Appreciation Application

SLIDE 7

AWARENESS

Most communities are unaware of vulnerability of neighbourhood to disasters (wind-prone, flood basin, seismic zone, landslide zone)

r proneness of the area to one/multiple hazards.
Lack of organised hazard-based risk

assessment for indicating – Mapping for the same – Vulnerability Atlas (Japan, Sri Lanka, India)

Awareness to permeate at the level of:

– Community / Beneficiary families – Practicing professionals – Building construction / Delivery groups – Building regulatory systems

SLIDE 8

APPRECIATION

On efficacy in the use of ‘safe’

and ‘time tested’ traditional/ technological construction practices providing for desired response / resistance to disaster induced forces / action / effects

LACK OF APPRECIATION:

On safe locations (prohibited sites and restricted sites with

precautionary limitations)

On the need to ensure effective quality control measures during

construction / execution stages or the disastrous implications thereof

SLIDE 9

APPLICATION

Safer building construction practices with disaster resistant/

protected planning, design and construction features would need to create enabling environment for application of all norms for safety namely:

– Structural Safety – Public Safety – Life Safety – Construction Safety

These can be ensured by adopting many action areas for

application.

SLIDE 10

IMPERATIVES FOR DISASTER RESISTANT INFRASTRUCTURE / BUILDING

EDUCATION

– Creating awareness among general public

use of audio-visual media [Demand Side]

– Awareness among students of technical

institutions Upgradation of curricula [Supply side]

– Capacity building of the concerned

agencies/ administrators

– To reform the building and infrastructure

delivery system, it is essential to provide training for the contractors, supervisors and master masons and workers in disaster resistant construction

NBC OF INDIA 2016

Built around the philosophy of creating and maintaining a Safe Built Environment for people and property by ensuring: Structural Safety Health Safety Fire Safety Construc?on Safety Electric Safety Environment Safety Life Safety Public Safety

ENFORCEMENT

To mandatorily associate the right level of professionals (architects, engineers, structural engineers, supervisors) of degree/ diploma or certificate level depending on:

The nature of building / infrastructure

(type, size, area, height)

The location (mega /metro city, medium/

small town and villages)

SLIDE 13

MAINTENANCE AND ASSET MANAGEMENT

Creating safe assets for disaster mitigation is important (CAPEX)
Calls for inspection systems at periodic intervals and carrying out non-

structural / structural upkeep, maintenance and repairs and “unsafe” buildings and infrastructure to be retrofitted

Equally important is to evolve appropriate

maintenance and asset management strategies and actions (OPEX) for ensuring safe and long term life and continuous functional performance of the infrastructure / buildings – to combat

bsolescence, decay and disfunctioning
Including Periodic Renewal Clearances – against “Safety concerns”
