Aga Khan Safe School Conference Islamabad 2008Garry de la Pomerai Theme 2 Key Note presentation

Theme 2 Technical Aspects of Seismically Safer SchoolsThis theme will focus on sharing, understanding and using of engineering designs/structural solutions for safer seismicresistant constructions schools, including school sites, especially in the mountain terrains. Issues related to design and

construction codes and guidelines, options for designs, and appropriate construction materials for school construction invarying terrain, as well as physical planning elements of hazard mitigation for critical infrastructure, will be brought

forward. Issue of insufficient and inefficient use of materials and building technologies will also be included. Modelsand good practices for safe school construction, prioritization of school retrofitting, cost-effective retrofit techniques,

etc. will be part of this theme

[boxed text to be displayed on power-point slides] [Remainder is the text of the key note speech]

The very first priority for school building safety is for every new school to be a safe school. This is

inexpensive when implemented consciously and diligently during design and construction of each new school.

Uniform building codes provide a higher standard for the performance of school buildings than for normal

buildings. An international rule of thumb is that school buildings be normally designed to be 1.5 x the strength

of regular buildings. Engineered buildings can be designed for higher standards of performance such as

being able to be immediately occupied after a severe earthquake to be used for shelter or emergency

operations. Whether new schools are built by local communities, through projects or programs of government

agencies, and/or with support from external donors, there is a need for clear and comprehensible building

guidelines provided with support from relevant government authorities. This usually requires cooperation

between ministries of education and a public works or construction standards authority.

The broader policy context for disaster-resistant construction involves:

standard building codes relative to hazard conditions

a transparent process for planning, design, regulation and enforcement decisions

qualification requirements for professionals engaged in engineering and design and construction of school

facilities

independent assessment of design, construction and maintenance of school facilities

technical support for all phases, and skill training for builders where needed.

active public stand against corruption, and liability for all contractors. This may include a zero tolerancepolicy, well-publicized campaign, and severe penalties for infraction.

independent ombudsman program for investigation of citizen concerns.

public awareness and consumer/community involvement in monitoring

Physical Statistics:

o In 2005 over 8,000 out of 9,000 schools were either destroyed or damaged beyond repair

by the earthquake.o Over 80% of schools in Pakistan remain unprotected from similar risks.

What causes structural vulnerability?

o Multiple hazards and reoccurring individual hazard events upon a community

o Poor building design and development planning with substandard construction methods and use of

substandard materialso Deterioration of buildings due to poor maintenance or accumulative minor structural traumas

o Lack of training for the builders and inspectors along with poor technical communication and liaison

When it comes to school safety, there are several basic assessment questions to be asked:

o Is the site itself safe, or can bit be made safe?o Are the school buildings themselves safe, or can they be made safe? What is the construction type? Is the

building designed to withstand the expected hazards (eg. elevated for flood, resistant to shaking by

earthquake or wind, roof to hold or deflect snow, insulated from cold and heat)? Do the construction

materials and the construction quality ensure the integrity of the building? Are temperature, air circulation

and noise-control accounted for?

o How safe are the buildings contents and non-structural building elements: Do the doors open outwards

for safe evacuation? Does each room have two ways in and out? Is the roof fastened securely to the

building? Is large and heavy furniture fastened to the structure to prevent falling or sliding in wind or

earthquake? Are utility pipes and wires flexible and secure with accessible cut off points?

o School physical safety is not continuously assured, by design and construction alone. Once a school

building is in use, it falls to staff, students and communities to accept responsibility for ongoing and

preventative maintenance and to regularly monitor safety conditions. A chain of command, adequatebudget, and training are all important in facilitating this. (For example, users may be unaware that thesingle most damaging element causing degradation of buildings is moisture and therefore that keeping the

ASSESSING SCHOOL SEISMIC SAFETY

Global examples

o Kathmandu, Nepal: The 1988 6.6 M earthquake in Udayapur destroyed 6000 schools.

Throughout Nepal.Today more than 6 million children and 140,00 teachers are at risk. (Alam, K.,

2007) Possible scenario of earthquake impact on school in Kathmandu Valley: In a no-

intervention scenario the expected loss is more than 29,000 school children dead or injured, and

more than 77% school buildings lost (est USD $7 million.) With intervention 24,000 lives can be

saved and the buildings protected. (Bothara, J. et. al. 2007)

o Bogot, Colombia: In 2000 the Directorate of Prevention and Attention of Emergencies in

Bogot, Colombia commissioned a study that identified that 434 of 710 schools were vulnerable

to earthquake damage, 3 were in flood areas and 20 prone to being affected by landslides In 2004

the 201 most critical were prioritized and structural reinforcement incorporated into 2004-2008

the Development Plan of the city (Coco, 2007).

o Republic of Uzbekistan: An assessment of 1,000 school buildings revealed that 51% were

require demolition and replacement with earthquake resistant buildings. 26% of the buildingsrequire capital repair and reinforcement 27% are life-safe and required no intervention.

building in good repair and preventing moisture accumulation is a significant priority). Users may also beunaware that the most common hazard in schools is fire.

Structural Technical considerations

o Transferable design between regions and communities must take into account material availability and the

logistics of acquiring the materials to site and they must be appropriate to the environment and to theexpected multiple hazards, not just to the predominant hazard.

o Good structural designs alone are insufficient without adequate quality control. This poses one of the

biggest challenges for all communities. We would all like a solution to this Global problem.o Periodic visual inspections by busy and possibly inadequately trained inspectors are not sufficient. There

has to be a working team of quality control to include the builder, site foreman, project manager, projectengineer, project architect and all in conjunction with building control officer. All of them must want tocomply with the set codes and necessary construction standards to ensure survivability for the children andteachers.

o Ignorance, time constraints, inadequate training, substandard materials and corruption are the common

enemies of building codes throughout the world. As an accumulative effect they spell disaster and death.o We must all want to alter our culture and approach to these problems. Without the will there is no

solution.o Some suggestions might include external inspecting project managers, independent of all others provided

by international agencies, but this has to be in cooperation with the local governance.o Certification of training / proof of competence for the responsible site workers to ensure their awareness

that there are key points requiring expertise understanding during installation to comply with acceptablecodes:

Codes to include:

o for reinforced buildings the Rheology of fresh concrete within foundations and of pillars and roof slabsIncluding Admixtures, Cement replacement, Accelerators/ Retarders, Plasticizers Durability anddegradation, Corrosion of embedded steel, Column buckling and Fracture mechanics, plus the correctinstallation of reinforcing within concrete including confinement by stirrups and ties; beam column

joints; structural diaphragms, foundation and grade beams;o Isolation pads and platforms, Bracing, and Joint mechanics within steel framed designs;

o Then bracing and joint ties and embedded timber floor lacing within Vernacular buildings.

See http://www.traditional-is-modern.net/KASHMIR.html

o Seismic bands at plinth lintel and roof level plus vertical reinforcement plus confining meshed plaster

on walls within adobe constructionso Non destructive testing, including simple slump tests of concrete, ensuring acceptable material

properties;o such as for concrete minimum compressive cylinder strength at 28days for high seismic zones

equals 3000psi and maximum compressive strength for light weight concrete equaling 5000psi;o for steel ASTM A615, grades 40 and 60 reinforcement, permitted if the actual yield strength

based on mill tests doe not exceed more than 124 Mpa (18000psi) and the ration of the actualtensile strength to the actual yield strength is not less than 1.25 and the value within transversereinforcement including spiral reinforcement shall not exceed 420 MPa (60,000 psi)

o Cover to steel reinforcement guidelines include:o in normal conditions

o 1 for exposed weather conditions

o 2 for exposed to soil conditions

Minimum compressive strengths of; Brick to be 1250psi; blocks at 1700psi; and mortar at 350psi

The most common hazard in schools is fire

o Fire prevention measures include: elimination and prevention of fire hazards; maintenance of

electrical equipment; standard fire prevention through awareness; smoke detectors, sprinkler

systems,

o Important measures to mitigating fire risk are: doors of classrooms and buildings open outwards for

safe evacuation; exit doors are clearly marked (above and below); exit route maps are posted on

each corridor and in each classroom ; fire suppression equipment is available on each corridor ; fire

suppression equipment is maintained regularly (eg. annual testing) ; staff and older students receivefire suppression training (use of fire extinguishers, blanket, bucket, sand, hose); schools conductregular fire drills

Lateral thinking

o Schools are a community asset and as such require that their development, maintenance and expansion be

carried out to an acceptable standard to reduce their vulnerabilities and increase their resilience toearthquakes and other hazards.

o Engineers and Architects including those who own, operate, maintain and repair schools should beconstantly thinking outside of their comfort zone to address the DRR challenges within Schoolsincluding:

o addressing multiple hazard vulnerability;

o to design the School as an post disaster community assembly safe building;

o to design to include future school expansion or alteration without threat to integral existing

strength;o to design as a transparent example of construction codes and safe practices for future hazard

resilient buildings within the community;o Community Engineers, Architects and Project/ Construction Managers should prioritise the need for

greater site liaison between each other and with local building control along with improved globalnetworking in order to develop researched safe practices of resilient design and implementation, notnecessarily embraced by codes, being discussed in Theme 1, especially for retrofitting;

o External Engineers, Architects and Project/ Construction Managers need to ensure a good understanding

of a communitys physical challenges to vulnerability reduction in addition to areas discussed in Theme 3:o Care must be given to review foundations proposals, especially within mountainous regions.

Determining if the land is liable to slippage or vulnerable to landslides during seismic activity,winters snows or heavy rains and if possibly affected by flash flood subsidence or snowavalanches.

o Reviewing location of a school within the surrounding geology and geographic features;

considering relocation maybe the only safe alternative

6

RELOCATION Moving the footprint

Global Examples

Philippines, Sta. Paz Sur; In the barangays (villages) of San Francisco

municipality, when school-children learned in 2006 that their high school was located in a landslide

risk area they debated whether and how to relocate the school. The headmaster opened the decision

to a community-wide referendum. The students were in favor of relocation, though parents wereconcerned about the extra travel time and loss of lunch business for local shops. Student

organizations in the high school developed an education campaign and their proposal won the vote

by 101 to 49. Students and parents constructed a temporary tent school with support from

International. The new permanent school will incorporate earthquake mitigation measures and

preparation for use as an emergency shelter (Action Aid, 2007).


7/11

On site challenges

o Reviewing a the schools location in respect of surrounding buildings, industry and future development

o Understanding construction challenges including the quality of available materials and a limited skilled

workforce; investigating the opportunity of personnel training prior to construction or retrofittingo The need to review the qualifications and training of building Inspectors and ensuring their supervision

o The need to implement and enforce design construction codes and safe practices;o To promote maintenance schedules, scheduled building inspections identifying building deterioration

including consideration of the accumulative affects of periodic minor quake and environment damages;o To raise awareness of the affects of architectural facia/venacular development, potentially threatening the

integral engineering design strength;

Successful structural DRR developments

Global examples

o Uttar Pradesh, India: There are23.5 million children attending school in this moderate to severeseismic risk zone.21,00 new school buildings (30 per day) have been completed in the past two

years. In 2006-7 the Elementary Education Department proposed to integrate earthquake resistant

design into all new school buildings. To prepare for this, one design of primary school buildings,

two upper primary and three additional classroom designs were prepared with detailed construction

manuals. The disaster resistant measures added 8% to the construction costs. To cope with massive

scale of the project a cascading approach prepared 4 master trainers for each of 70 districts. These

individuals in turn conducted trainings for 1,100 fellow Junior Engineers and Education Officers.

10,000 masons were also trained. This program means that every new school will be a safe school.

Within a relatively short period, most children will be attending safe schools. However, the pre-

existing stock of 125,000 school buildings remains unsafe and in need of retrofit (Bhattia, 2007).

o Nepal, Kathmandu: A vulnerability assessment of 1,100 buildings in 643 public schools revealed

that an alarming 60% of buildings are highly vulnerable even under normal conditions. A rollingdemonstration project is underway that undertakes retrofit of a school while simultaneouslytraining local builders in techniques of disaster-resistant construction and training teachers, studentsand parents the basics of risk mitigation and preparedness. Protection of Educational Buildingsagainst Earthquakes: A Manual for Designers and Builders documents the rich experiences gainedduring implementation. Extensive public participation through a district level advisory committee,school management committee and school earthquake safety committee and student club, created a

replicable model. Thiso now requires resourcing to implement comprehensively (UNISDR, UNESCO, 2007).

o Peru: One particular structural weakness, short columns are a common design fault that

compromise the safety of many school buildings. A retrofit solution was developed to partiallymitigate this potentially devastating structural defect. (UNISDR, UNESCO, 2007).


8/11

School Retrofit and Replacement

o Tackling the strengthening or replacement of existing buildings to resist recurring hazards requires

a careful and scientific strategy for prioritization, both to target efforts for maximum effectiveness, andto manage costs.o For most authorities, detailed assessment of a large number of buildings is not practical. A

prioritization scheme, using a filtering method needed to identify the highest risk buildings for retrofitor replacement.

o A general model for prioritization is based on the vulnerability of the buildings, the existinghazards, and building occupancy; using a transparent and technically based schema, beginning with a

paper review of existing school building stock, selecting those for sidewalk survey, using sidewalkassessment of existing buildings (using, for example the ATC 21 survey or modification of this) toselect high priority buildings for detailed assessment, using detailed assessment of these buildings toidentify those for priority retrofit (Grant et. al, 2007)

Recent proactive commitments to School retrofit

Global examples

Turkey, Istanbul: Following the 1999 Kocaeli earthquake, schools 60km away in Istanbul were

assessed; 820 of 1,651 schools had sustained damage. Thirteen were immediately, identified for

replacement. When retrofit proved too costly 22 more were added to this list. 59 schools were

strengthened, and 59 repaired. (Wisner, et. al. 2004).

Uzbekistan: Eleven Design Institutes participated in building codes revision for school building

construction. Typical designs were created for new schools with different capacities. A database of

typical construction and technical decisions for anti-seismic reinforcement were developed. UNCRD

provided financial and technical support for demonstration projects on reinforced concrete frame,

masonry and frame panel buildings. The incremental cost of seismic reinforcement was shown to be

between 3-14% depending on intensity zone, type of construction, number of floors, capacity and

ground conditions. (Khakimov et. al. 2007).

Colombia, Bogot: 47% of school infrastructure benefitting 300,000 students is being improved or

replaced in Bogot with $162.7m USD for structural reinforcement of 172 schools and non-

structural risk reduction in 326 schools (Coca, 2007).

Central America: The Organization of American States began its commitment to school safety in

1992. A coordinated regional action plan has been developed to benefit Costa Rica, El Salvador,Guatemala, Honduras, Nicaragua and Panama has created a mechanism to combine the contributions

of development assistance donors with contributions from local organizations to develop strategies,

and capacity to carry out retrofitting of educational facilities. School infrastructure experts from each

country are being trained

Canada, British Colombia: Responding to advocacy efforts of the local Families for SchoolSeismic Safet , in 2004 the rovincial overnment committed $1.5 billion Canadian to ensure that

School retrofit demonstration models

Global examples

o India, Shimla: Structural assessment of school buildings was carried out using a

filtering method: The first step was low-cost mass scale Rapid Visual Assessment Survey of schoolbuildings for potential seismic hazards. Based on these surveys a smaller number were selected forSimplified Vulnerability Assessment based on limited engineering analysis, and the highest riskidentified for Detailed Vulnerability Analysis. Following this retrofitting designs were drawn up for20 schools and implementation of retrofit carried out in 8 schools. Program includes development ofguidelines for retrofit and training of local masons and engineers, and delivery of skill-training.Non-structural mitigation plans have also been carried out in 20 schools. An awareness campaignis designed to reach all 750 schools in the region including nearly 100,000 students, 7,500 teachersand local builders, engineers and officials. (SEEDS, 2006).


9/11

Community ownership is the Communities first step to structural Disaster Risk Reduction

o Commencing by raising fundamental awareness questions within hazard vulnerable

Communitiesaimed at ensuring continuity of service of the school infrastructure through the development andinclusion of DRR within education as discussed in Theme 4

o Is there a hazard vulnerability history within your community or region?

o Do you know which schools are vulnerable, and to what, why and how did they get thatway?o Who is responsible and accountable and who will pay?

o Have you investigated the costs of retrofitting the school?

o Are your local builders trained correctly?

o Do you have building codes, permits and /or licences to work to?

o Do you have readily available trained inspectors and supervisors?

o Are all necessary recommended materials available to your community?

o Do you have a successful example of retrofitting within your region?

o Do you understand Non-structural mitigation within your school buildings?

o

Do you have the support of the community and local government Administration?

And have you considered your community resource mobilization?

By taking ownership through the parents and teachers and community themselves as stakeholdersas discussed in Theme 6, requiring no administrative input nor financial commitment, by startingwith the basic non-structural internal and external mitigation considering specifically designedDRR fixtures and fittings and reviewing safe positioning and fixings and their effect uponstructural design functionality

PHYSICAL PROTECTION Community check listOur building has been located appropriately, designed and built according to current buildingcodes/safety standards for disaster safety, and inspected by a qualified structural engineer.

If our school required repair or retrofit, this has been completed without minimal disruption ofstudents's education.

We practice preventative maintenance on our buildings, protecting them from damp and otherdamage, and repairing damage when it occurs.

Earthquake, windstorm: We have fastened tall and heavy furniture, secured computers, televisionsand other electronic equipment, hazardous materials, supplies, propane gas tanks, water tanks,lighting fixtures, roof elements, railings and parapets, heating and cooling devices, storage tanksand other items that could kill, injure, or impair educational continuity.

Earthquake, windstorm: We have put latches on cabinets, and hung pictures securely on closed

hooks to protect ourselves from things that could injure us, or would be expensive to replace.Flood, storm, tornado: We know about early warning systems and have plans to respond to theseto move people and assets to safety.

We have smoke detectors, fire alarms, automatic sprinkler systems, fire hoses, fire extinguishers,and automatic emergency lighting, and maintain these. Our building exit routes are marked.

9


10/11

We have limited, isolated, and secured any hazardous materials to prevent spill or release.

We have off-site back up of critical information. (including student emergency contacts andrelease permissions.)

School transportation is inspected for safety, drivers and students are trained in respective safetyskills. Seat belts, helmets and other transportation safety measures are advocated and promoted.

Finally in addition to coded design principles, a Community must not forget to address DRRthrough the enhancement of escape routes , reviewing existing, creating new, including

establishing safer assembly areas and potential internal safe havens, all in conjunction with Theme5 addressing drills and preparedness training.

To assist your communities COGSS Coalition for Global School Safety internationally fostersdialogue and collaboration between advisory groups of local scientific and field practitioner experts fordevelopment and localization of Disaster Risk Reduction strategies through the use of educationalmaterials and structural resilient design.

NON-STRUCTURAL RISK REDUCTIONGlobal Examples

USA, California: The 1994 Northridge earthquake happened at night when no

children were in school, but the damage caused by fallen cabinets, bookcases, equipment,

lighting fixtures and broken glass made it clear that during a school day, children, teachers and

staff would have been injured and killed by falling, sliding and colliding objects. The Los

Angeles Unified School District amongst others, embarked on a project of non-structural

mitigation of school classrooms, fastening furnishings to prevent both injuries and to preserve

school assets. This effort continues today and is the responsibility of each school and school

maintenance personnel.

India, Delhi: NGO partners SEEDS and GeoHazards International, workingwith the Government of Delhi, have demonstrated non-structural risk reduction in a public

school. The school welfare committee comprised of faculty, staff and local community

members learned to identify the non-structural building elements and building contents that

could fall, slide or collide during a likely Delhi earthquake, as well as fire and evacuation

hazards. They were exposed to simple low-costs techniques for reducing these risks (moving

some items, fastening others) and came up with innovative solutions of their own. The logic of

regular fire and earthquake drills became readily apparent to these new stakeholders. A

handbook for schools on Non-Structural Risk Reduction provides a new resource for

NON-STRUCTURAL RISK REDUCTION

Practical Examples

(Fastening building contents and building non-structural elements to avoid deaths, injuries

and material losses in earthquakes and other hazards.) tall and heavy furnishings, bookshelves, cabinets and similar items that may

topple and fall, must not block exits, and should be moved to a place where it will not hit

anyone, or be fastened to the building so that it moves with it.

water tanks, heating, ventilating and air cooling units should be secured to the

building to prevent toppling

hazardous materials in labs should be limited, isolated, eliminated or separated

and stabilized.

Finally, considering the continuing challenges in the creation and more importantly the enforcement ofCoded designs and construction standards within vulnerable multiple hazard communities, and in supportof the Aga Khan Planning and Building Service and this Conference I am pleased to announce an intendednew initiative, that global technical networking is to be assisted by the proposed creation of SSSAFESchool Structural Safety Advisory Forum Executive made up of invited globally recognised Engineers,Architects and field Project Managers. The role of the executive is to act as a discrete global forum andfocal point to review and discuss codes and good practices, raise issues, and introduce and encouragespecific research, individual ideas and methodologies, administered through COGSS. The objectives areto assist creating a coherent globally coordinated strategy in developing safer resilient designs and retrofit

procedures for all new and existing schools within vulnerable and hazardous environments.
