1.0 INTRODUCTION

1.1 Objective

The objective of this document is to look at the vulnerability of school buildings to natural hazards in Antigua and Barbuda. Special consideration should be given to school buildings because they often serve as shelters in times of disasters. This plan outlines the existing conditions in Antigua and Barbuda and makes recommendations on how to better protect them from natural hazards.

1.2 Use of this Document

This document is intended for use by the Ministries of Education and Public Works, the National Office of Disaster Services (NODS), the Board of Education, the Development Control Authority (DCA), as well as the Central Government as a whole. This plan paints a clear picture of the existing stock of school buildings and the roles and responsibilities of the organizations involved.


2.0 SCHOOL CONSTRUCTION SECTOR

2.1 Profile of School Buildings

There are 71 schools in Antigua and Barbuda, 39 government schools and 32 private institutions. Schools vary from two-story to single-story structures. Many use designer concrete blocks for ventilation while others have louvered windows or shutters. The basic materials used in construction are concrete, brick, mortar, timber, and corrugated zinc sheeting for roofs. Some schools built before 1970 have asbestos material in their roofs, however, this is gradually being replaced.

2.2 Responsible Agencies and Collaborators for:

a. Design

Board of Education, Ministry of Education, Ministry of Public Works and Community Groups

The Ministry of Education and the Board of Education set out the criteria for the use of the school and the Ministry of Public Works provides the architectural and engineering specifications.

b. Construction

Ministry of Public Works, Board of Education, Health Department and Development Control Authority (DCA)

The Ministry of Education and the Board of Education provide funding, while the Health Department makes sure that all waste water and sewage is in its proper place. The DCA makes sure all building guidelines set out in the state are followed by the Ministry of Public Works who implements the construction and follow all guidelines.

c. Reconstruction after Destruction

Ministry of Public Works, Board of Education and the Ministry of Finance

The Board of Education provides funding for reconstruction and, if necessary, the Ministry of Finance. The Ministry of Public Works is responsible for reconstruction.

d. Retrofitting

The Ministry of Education, Board of Education and Community groups all have a role to play in the retrofitting of our schools/shelters.

Retrofitting requires collaboration between the Ministry of Education and the Board of Education and specified community groups.

e. Repair After Damage

Ministry of Public Works and Board of Education

The Board of Education and the Ministry of Public Works carry out repairs.

2.3 Building a Profile and Data Base Process

The Ministry of Public Works, the Ministry of Education and the Board of Education all have a vested interest in proper data base information which will provide them with the information necessary to analyze these structures for future development.

The task should be carried out jointly by the Ministry of Public Works, the Board of Education and the Ministry of Education. This will allow for the proper keeping of information and the update of the same. This will allow more efficient problem solving in our school maintenance programme.


3.0 PREVALENT NATURAL HAZARDS

3.1 Hurricanes

The impact of hurricanes is recorded in the archives of Antigua and Barbuda and dates back to 1642. However, in living memory, one often hears of the hurricanes of 1950/51. These hurricanes accounted for the total elimination of several villages. Injuries and deaths were reported to be as high as fifteen per cent of the population. The damage to the agricultural sector was extensive, which later resulted in extreme hardship for the inhabitants of the island, as agriculture was the main industry.

In recent times, Antigua and Barbuda has been struck by Hurricanes Hugo in 1989 and again by Luis and Marilyn in 1995. Although Hurricane Hugo did not impact on Antigua and Barbuda directly, the damage was fairly significant. This served as a wake up call for those Antiguans born after 1950/1. The damage to the school plants was fairly extensive as was the damage to other sectors of the economy.

Hurricane Luis, however, was the most destructive force of nature to grace this twin island state of ours in the memory of any Antiguan alive. In a small developing country with its population a mere 63,000 people, the estimated damaged caused by Luis was put at $500 million. This figure by itself gives an idea of the type of destruction the impact caused. Thirty-seven government schools and nine private schools out of a total of 71 were damaged. (As states earlier, there are 39 government schools and 32 private schools in the country.)

As a result, some schools were closed, as others had to share the facilities by way of a shift system. This was due in part to the nature of the damage to some of these facilities which ranged from roofs totally blown-off, windows and doors destroyed or badly damaged, flooding, etc.

Annex 10.5 contains additional information pertaining to hurricanes.

3.2 Earthquakes

Antigua lies in the Caribbean belt, where activities along the northern and eastern boundaries of the Caribbean plate cause the majority of earthquakes that we feel. Antigua and Barbuda is part of the tectonically active Circum-Caribbean belt

Records of the destructive earthquakes date back to 1819. However, the most recent was the earthquake of 1974, which caused wide spread damage and destruction to several buildings and the infrastructure costing millions of dollars.

For more information on seismic vulnerability, please consult William McCann’s article, "On the Earthquake Hazards of Puerto Rico and the Virgin Islands" published in the Bulletin of the Seismological Society of America, Vol. 75, No.1. (February 1985): pp. 251-262.

3.3 Volcanic Eruptions

Many local residents are of the view that a volcanic vein is located beneath the historical landmark of the St John’s Cathedral. However, the Seismic Research Centre in Trinidad and Tobago in a report submitted to NODS indicates that there is no scientific evidence to substantiate this claim.

Although Antigua has no known volcano, we are in very close proximity to Guadeloupe in the southeast, Dominica in the south-southeast and Montserrat in the southwest. All of these islands have volcanoes that can negatively impact on the way of life, for the people of Antigua and Barbuda if or when they erupt.

The Soufriere Hill volcano in Montserrat became active on the 18th July, 1995 and is located some 30 miles southwest of Antigua. Recently, Antigua has felt the effects of this volcanic eruption particularly when there is a change in the wind direction. On at least one such occasion, schools had to be closed and most businesses operated at a level well below their usual scale.

3.4 Floods

There is no recorded data to indicate that in the past Antigua had any significant impact caused by flooding. In recent times however, certain development activities have brought cause for concern. The interference with some natural watercourse has caused severe flash flooding in some areas to a magnitude unfamiliar to these areas.

3.5 Droughts

History reveals that at least two attempts were made and abandoned before the European settlers eventually inhabited Antigua and Barbuda. This was primarily due to the lack of water on the island. In recent times, the droughts of 1984 and 1995 would be fresh in the memories of Antiguans and Barbudans.

In 1984, Antiguans witness the almost total collapse of the agricultural sector. The livestock industry suffered loss in the region of about 40 percent, and water had to be barged in from nearby Dominica. The contraction and expansion of soil due to dry and wet weather have some implications for the site selections of our schools/shelters and the building techniques used if we are to avoid or minimize negative impacts in the future.

Unlike other disasters, the effects of droughts are often very slow to detect and in some cases are not detected at all. Members of the agricultural sector tend to accept losses as a natural occurrence and are reluctant to attribute damage to drought.

Annex 10.3 contains additional information pertaining to rainfall.

3.6 Landslides

There is no evidence to indicate that Antigua had any significant landslide problems in the past. However, there are signs that this will change in the future as burning and other forms of clearing hillsides for agriculture and housing purposes indicates that the removal of hillside vegetation may result in slippage.

A small incident of slippage in the Fig Tree Hill Drive area occurred after Hurricane Luis. Soil erosion during flashfloods normally leaves its mark on the agricultural sector as important topsoil is often washed away.


4.0 VULNERABILITY OF SCHOOL BUILDINGS

4.1 Methodology

A pilot study was initiated to analyze the vulnerability of twenty selected properties in Antigua and Barbuda. The properties analyzed are listed in Table 2, a comprehensive profile of the properties is contained in section 4.2. Information pertaining to seismic vulnerability and the wind hazard was gathered using the survey found in Annex 10.8 and through interviews with key personnel including principals, teachers and other community members. The results of this survey will be available in September 1998.

5.0 POLICIES

Objectives: To develop and enforce building codes, to specifically address the design and construction of school buildings or shelters. The end product of this task should be the birth of a model building that can be duplicated and manipulated in any location.

5.1 Existing Policies that Pertain to School Buildings and Shelters

The Development Control Authority (DCA) is a government organization charged with the task of monitoring and regulating the construction industry. The DCA is guided by the Building Regulation Act, which contains building codes and guidelines for construction. These codes, however, do not contain any clauses that define an acceptable level of vulnerability to natural disasters of shelters or schools. Consequently, communities are put in a position where they are forced to use buildings for emergency shelters which were not originally designed for that purpose; a point which was reinforced after the last two hurricanes (Hugo 1989 and Luis 1995) where we experienced major destruction to many shelters and unnecessary discomfort and distress to the shelter occupants.

It is, therefore, imperative that, in an effort to safeguard life and property, the DCA immediately revisit its Building Code and address the shortcomings by specifying acceptable levels of vulnerability to natural disasters of all schools and shelters.

Such a task will require an investigation into the following:

a. Traditional Building Practice

The traditional details employed in the construction industry must be analyzed for performance standards and where they are found to be inadequate, new details must be developed to reduce the risk of destruction by earthquakes and hurricanes. For example: the practice of toenailing rafters and studs must be abandoned in favour of more efficient methods of fixing such as bolting and strapping rafters to each other and to the foundation.

b. Site Selection and Specifications

Where new schools or shelters are to be constructed, the site must be carefully selected according to specified guidelines to reduce vulnerability to natural disasters. Flood plains and exposed ridges and cliffs should be avoided in favour of more sheltered locations. A minimum high of 12" should be established above grade at the datum of all ground floor level.

c. Design Criteria

Provision must be made for the inclusion of the following facilities to all new shelters:

d. Maintenance

The maintenance of schools is the responsibility of the Ministry of Education supported by the Board of Education, and the Ministry of Public Works. The Ministry/Board of Education must clearly define its role as it relates to private schools.

Maintenance should be preventative rather than the practice of repairing after damage is done. A recurring budget must be provided for this purpose. The establishment of a maintenance team and the identification of a supplier to provide materials in an adequate and sustained manner must be put in place.

The policy of assistance to private schools must be clearly defined and communicated to them so that access to assistance from the Board of Education can be realized.

e. Community Involvement

Community action groups must become an integral part of the Central Government’s policymaking to ensure that they have input in decisions taken that will ultimately affect them during emergency situations.

There is much concern over the ability of the DCA to adequately enforce the building codes and any guidelines that may be adopted. It is imperative to the integrity of our schools/shelters, that DCA is provided with the necessary tools to be able to enforce the building codes. This may require new legislation, additional staff and training, and a strong commitment from government. Unless the DCA is empowered to implement the building codes, no new policies can or will have the desired effect.


6.0 PROCESSES

6.1 Diagrams of Planning Processes in School Infrastructure

a. Design

The government, through the Ministry of Education, commissions a plan for the design and construction of a school plant. This is done after much careful assessment of the educational and social needs of a particular community.

With prior and present knowledge of the physical aspects of the designated area for the school plant, the Board of Education then puts out a tenders notice for suitable designers and contractors to develop the project. In some instances, the Ministry of Public Works may be contracted to carry out the developments or a part thereof. Such a plan would involve a number of units, their location and sizes along with the classrooms and other facilities deemed necessary.

However, it should be noted that most of our schools are gifts from foreign governments with little or no local input into their design and construction, and in most cases, are inadequately designed to be used as emergency shelters.

As a part of the government’s programme to reduce the vulnerability of school plants, the CDB has recently approved a loan package designed to carry out improvement exercise for nine government schools.

Design of schools is also based on the amount of financing that is available which, in most cases, determines to a large extent the vulnerability of these structures to natural and or man made hazards, especially during a disaster.

Some schools are built in low-lying areas to avoid the direct impact of hurricanes. For example, the Cedar Grove School, while others are constructed outside the heart of the community.

Most of our schools plants have been constructed using inadequate design of the roofs, which gave rise to over three-quarters of them loosing their roofs in hurricanes Marilyn and Luis. The gable roof design has proven to be vulnerable to hurricane force winds.

b. Construction

The Architectural Design and Construction Division in the Ministry of Public Works is responsible for ensuring that all relevant elements of the building code and any other considerations are taken under advisement to ensure that school buildings are built to the acceptable levels of vulnerability.

c. Reconstruction

Reconstruction should be carried out only after all the necessary assessment has been done. During all stages of reconstruction, every effort must be made to apply mitigation measures.

This should only be undertaken after the type and cause of damage is ascertained to the roof, and other parts of the super-structure. Existing construction should be improved by using adequate retrofitting measures. For example, larger and stronger materials, and safer fastening methods should be used. The reconstruction of a unit should not to be done in the same fashion as previously construction if the building was initially inadequate. However, the uniformity of the structure should be maintained.

d. Retrofitting

Retrofitting is the implementation of major repairs to a structure for the purpose of changing or modifying the construction to withstand the effects of potential hazards. An inventory of retrofitting exercises should be kept on all building. Retrofitting must be carried out as a result of much planning and always for maximum benefit.

Data should be kept on natural hazards that have affected the school infrastructure, so that retrofitting can be carried out with an aim to prevent any such problem from reoccurring. A division should also be created within the Ministry of Public Works to deal specifically with the maintenance and construction of all government schools, based on certain guidelines dealing with the reduction of the vulnerability of school infrastructure to natural hazards.

Drawings showing all connections of services, shutoff valves, main switch, plan of the buildings, and utility and plumbing plans should be kept at the school. Ideally, a trained individual should be posted at the school/shelter to cope with any sort of accident, etc.

e. Repairs

Repairs should be carried out frequently, especially where the building suffered structural damages cause by settlement, earthquakes, heavy rains, and/or droughts. A period of 12 to 18 months should be use as a yardstick for engineers to check school/shelter buildings for maintenance of the superstructures, while a more frequent check can be done for other repairs.

An inventory of all government schools is presently being conducted to establish the need for retrofitting. This information will be used to put in place some form of prioritized listing, so as to improve the present condition of all schools. The basic necessities for emergency situations, such as a kitchen, bathrooms, water tanks, cistern, electrical generators and other vital resources must be put in place.

6.2 Building Capacity

School buildings are used for quite a number of different activities. With this in mind, they should be designed and constructed owing to this situation. Building capacity is determined by its design and construction, rather than by its size. Most of our schools are designed to accommodate children and not adults. During emergency situations, these facilities are stretched beyond their capacity to accommodate the accompanying adults. This places the infrastructure under severe pressure and actions must be taken to correct this problem.


7.0 PROJECTS

7.1 Mitigation and Retrofitting

Mitigation, retrofitting and repairs are the responsibility of the Ministry of Education, supported by the Ministry of Public Works, and the Board of Education. In the areas of preventative maintenance, we should upgrade these facilities to allow for better functioning of the school plants. By doing this on a regular basis, the cost of retrofitting can be tremendously reduced. Failure to mitigate and retrofit could lead to excessive spending in the future which will far outweigh the regular mitigation and retrofitting costs if done on a timely basis.

7.2 Design

The design of schools is the responsibility of the Ministry of Public Works with the specifications given by the Ministry of Education. The construction criteria is set out by the Ministry of Public Works, Design and Construction Division, which deals with the engineering of the structure to meet the specified building code and all architectural needs.

7.3 Site Selection

Site selection is normally done by the Ministry of Education based on the availability of land in the selected area. This practice should be discontinued and sites for schools should have specific guidelines to relieve vulnerability to natural hazards such as floods, hurricanes, earthquakes, etc. See Section 5.

7.4 Financing

Schools are financed through several sources, government, CDB and donor agencies. Funding by CDB and donor agencies is given with specific guidelines set out as to what the responsibilities of the government are relative to the project. In most cases, the funding agencies normally provide government with a turnkey project, which does not allow local input at the design stage. This practice must be discontinued to allow for local vulnerability and mitigation concerns to be interjected.

7.5 Community Involvement

Community involvement allows objective organizations and individuals the opportunity to represent their community. These individuals bring with them a wealth of knowledge in a variety of subject areas, which can enhance the overall development of the community.


8.0 PREPAREDNESS

8.1 Existing Country Plans and Strategies

There is no disaster plan in the Ministry of Education. There is, however, a broad National Disaster Plan. In addition, the National Emergency Operation Center (NEOC) guidelines for Antigua/Barbuda are in place.

There is a need for a disaster plan within the Ministry of Education, the following guidelines are suggested:

8.2 The Role of Teachers and Students

8.3 Links to Curriculum Development

The prevalence of natural disasters and the impact they have on our lives should be integrated into the existing school curriculum. A more permanent place in the overall educational system for this subject should be found with emphasis placed on those natural hazards that are known to affect Antigua and Barbuda.

An option would be to include this subject in the Social Studies Programme. Beneficiaries would be at all levels (kindergarten, primary schools, secondary schools and Antigua State College).

8.4 Links to Community Involvement


9.0 RECOMMENDATIONS

  1. Buildings should be constructed at least 12 inches above grade.
  2. Bearing capacity of the soil should be taken to determine type of foundation and building technique.
  3. Adequate reinforcement should be used such as bolts, clamps, straps, etc.
  4. Grade-A materials should be used when constructing wooden buildings and a minimum gage of 24 galvanized sheeting should be used for roofing construction.
  5. Design for proper ventilation and lighting must be taken into consideration and, if necessary, special venting for stormy weather to relieve pressure.
  6. Each building should have independent toilet facilities.
  7. Decorated blocks should not be used in the construction of school buildings without due thought to the use of the building, especially in times of disasters.
  8. Construction of school roofs should be much steeper than present and be of hip roof design. Where gable is used, a parapet wall may be considered.
  9. Sizes of roofing materials should be of larger cross sections and avoid using two by four rafter and wall plates.
  10. Where possible, metal doors should be used.
  11. Keen attention should be paid to the layout of infrastructure such as roads, drainage, recreation, parking, agriculture and science areas, etc.
  12. Due consideration must be given to the environment and its protection.
  13. The maintenance team must be multi-skilled, with responsibility for the maintenance of all government schools.
  14. The policy of site selection, design, soil testing and collaboration between all principle parties must be adhered to.
  15. The present policy of a sinking fund instead of insurance coverage for schools is one that, if properly administered, could have a positive impact on the education system. This responsibility should be given to the Board of Education.
  16. The necessary support must be given to NODS to complete a Disaster Preparedness Plan for the Ministry of Education. Once a draft is complete, all schools must develop their own, school specific plan.
  17. Future school construction must be carried out based on this plan whether it is financed with local funds, grants from foreign agencies or governments, be it private or government.
  18. The collection of school vulnerability data must be completed by 1st July, 1998, for all schools in Antigua and Barbuda and entered into the computer system at the Ministry of Public Works, the Board of Education and the Ministry of Education. It should be updated every nine months.
  19. Over the next eighteen months to three years, a vulnerability study must be carried out on all government buildings, and the data computerized for further use in a retrofitting programme.
  20. Profiles of school buildings should include the date of construction, vulnerability analysis to specific hazards, a maintenance update, history of damages caused by hazards, construction specifications and any other relevant information.

10.2 Mandates Related to Vulnerability Reduction in the Education Sector

Permanent Council of the OAS, CP/ RES 546 (834/90). October 10, 1990

Resolution 3: To encourage member states to make natural hazard management and disaster relief integral components of their socio-economic development activities.

International Decade for Natural Disaster Reduction 1990-2000 (IDNDR) which was proclaimed by the General Assembly of the United Nations by Resolution 44-236.

Permanent Council of the OAS, CP/RES 593 (922/92). October 28, 1992

Resolution 4: To encourage member states to undertake natural hazards vulnerability reduction programs as an integral part of their efforts to alleviate conditions of poverty and underdevelopment and achieve sustainable economic growth.

Declaration of Cartagena, Interamerican Conference on Natural Disaster Reduction. March 21-24, 1994

Recommendation 2: In the understanding that such vulnerability is one of the shortcomings of underdevelopment and environmentally- harmful actions, it is essential to co-opt the political willingness to recognize that such vulnerability should be among the explicit objectives of sustainable development planning and an indicator of environmental impact accountability. The development of monitoring techniques and the tallying of disaster vulnerability factors must be seen as essential tools for disaster prevention and mitigation.

Recommendation 3: There is a need for eliciting greater community participation to gain greater in-depth understanding of individual and collective perceptions on such developments and their attendant risks and to assess the cultural and organisational features of the societies, aside form their behaviour and relationship with their physical and natural environment, which may hamper or enhance prevention and mitigation as well as those that encourage or hinder the protection of the environment for the development of future generations; these being fundamental aspects in the definition of effective and efficient resources to mitigate the impact of the disasters on the region.

Recommendation 5: Given the importance and validity of cultural aspects during disasters, there should be the strengthening and encouragement for educational programs for the population and training programs for researchers, planners, experts and officials so as to provide them with adequate, diversified knowledge of the realities in the region in order to incorporate preventive aspects not in the culture.

CIECC (Inter-American Council for Education, Science and Culture), OAS/RES 1995
