The purpose of this paper is to investigate increase in the cost of reinforced concrete buildings in Kathmandu valley constructed using earthquake safer features in comparison with that of buildings constructed using conventional approach without earthquake safety features.
Five buildings constructed using earthquake safer features and five buildings constructed without using these features are selected. A cost comparison of both types of buildings is done, and the total cost is also compared for structural, nonstructural and service components in the buildings.
The cost analysis of buildings constructed in Kathmandu valley shows that there is 10 per cent increase in cost for earthquake safer construction in comparison to construction using conventional approach. This increase in cost can be a deterrent factor for house owners to switch to safer construction practices which ultimately leads to lack of compliance from house owners. A successful implementation of building code in a country like Nepal, where most of the buildings are constructed from informal sector, requires compliance of the code from all stakeholders. Awareness raising can be a deciding factor for success in building code enforcement.
The study is done for only two types of constructions prevalent in Kathmandu: one using simplified codal method and another using conventional method. Only five samples of each types are taken into consideration. The building sample, however, is typical and representative of the two types of the construction practice.
The information from this study will be useful for making policy decisions for enforcement of building codes and also for assessment of economic loss in future earthquakes.
This research output will help to redesign building code enforcement projects in Nepal and other countries in the region with similar issues.
The building samples, analysis and output are original contribution of authors, and it contributes to fulfill the gap for such study.

Nepal's urban population is estimated to be around 15 percent. This is a tremendous increment considering that the urban population some 50 years back was just around 3 percent. The rapid increase in urban population in the last five decades has resulted in unplanned and haphazard urban growth. Urbanization causes a shift in employment, from the agricultural sector to the nonagricultural sector. However, in Nepal, despite the increase in the urban population, the economy is still largely dictated by the agricultural sector. Urbanization is creating and adding new risks to the existing risks from natural hazards such as earthquakes, landslides, and flooding. Building a culture of safety is the key to building resilience of communities to disasters and the involvement of the community in managing risks is instrumental in reducing the adverse impacts of these disasters. Public awareness in dealing with disasters and in responding to emergency situations can save a great number of lives.

As the widely held perception is that retrofitting is a complicated process and is expensive, the purpose of this paper is to analyze cost effectiveness of retrofitting existing buildings in order to make them safer against earthquake and also to add child friendly features. This case study focuses on the simple method of retrofitting on rectangular single storey existing school buildings. The school buildings are of different types, based on material, shape and size, number of storeys and their vulnerability to earthquake is different case by case. The paper also outlines the process of vulnerability assessment and approach to retrofitting.
The paper is based on the data collected from a case study carried out in Aceh (Indonesia) as a part of an assessment of vulnerability of newly constructed school facilities and retrofitting them in order to increase their seismic performance.
One of the key findings of this study is that retrofitting can be achieved through the use of simple methods, tools and equipment and local human resource. This approach not only reduced the vulnerability of school children to earthquake disaster but also contributed to disseminate the message of culture of safety among the neighboring communities. Another major finding is that cost of retrofitting is less compared to the cost of demolition and rebuilding. The retrofitting option further saves the cost as it is time saving and the downtime is less. The retrofitting process and onsite training can also be an effective medium for dissemination of best construction practices in the community. The process also helps the local people to understand the context of risk and raise awareness on disaster risk reduction.
The findings of this paper are not limited to vulnerability assessment and retrofitting of school building in Aceh. They can be replicated in other parts of Indonesia and countries having similar type of buildings.
The findings of this paper will be useful for decision makers to replicate similar processes in other types of schools in other areas. The findings will also be useful advocate disaster safer and child friendly schools.
The paper is unique in its findings that retrofitting of school buildings does not only make the schools safer and reduces the risk to children but is also cost effective compared to new construction.

Three years ago, Naina Shahi's husband left their small village in rural Nepal to seek work in neighboring India, leaving her to bring up their three children alone. The dry winters and unpredictable monsoons Nepal has experienced in recent years had hit crop production on the couple's land plot in the foothills of the Himalayas, forcing them to look for other ways to feed their family (A report in September 4, 2009 issue of Republica; Cozens (2009)).
