Abstract
Historic buildings have a lot of contributions to the development and prosperity of a city. The primary contribution of these historic buildings is to provide the city’s historical information such as past events, continuity of change through time, periods of ascendancy of remarkable events, or ruptures in the urban fabric as a result of conflict or transformation. In this thesis, the writer attempts to carry out an investigation on Harar Jugol aged traditional houses by studying the characteristics of the original materials used to construct the houses and by examining the maintenance work being carried out at present. These two major objectives show the importance of these historical buildings in its historical and current contributions.
One significant problem of the historic Harari traditional Houses is the lack of timely and appropriate maintenance for these invaluable and unique buildings for which Harar is registered as fortified historic city by UNESCO. The investigation is carried out by direct questioning of the stake holders such as Harari cultural and Youth office, Harari cultural and historical monument and the residents of the aged traditional houses. Since the residents as well as the characteristics of the original materials used to construct the traditional houses are directly responsible for the damage of the houses, the study focuses on the Investigation on Harari Traditional Aged Houses Maintenance Work examination of the problems of earthen materials or soils by making a test on physical, chemical and mechanical properties of the four types of soils (Gogoba, Kuyesa, Browinish soils and Sandy soil).
As already clearly stated, everybody agrees that these buildings need maintenance because of the damage coming from environmental factor and the old age the building passed through. Therefore, special maintenance care must be taken by studying the original materials and the technology used to construct the buildings. This helps to make proper maintenance which conforms to the original quality of the buildings. To examine the effectiveness of the maintenance work, investigation is carried out on one hundred houses by using proportion sampling method to address all the houses. Finally, the paper concludes with the result gain of determining the quantity of water used for making soil mud required as a paste to stick the stone one to the other and the problems encountered by using cement paste for maintenance by the inhabitants which is different from the original materials out of which the houses were constructed. This paper also shows the current status of the houses and suggests the maintenance work to make effective technical output and the responsibility of the local government as well as the residence of the houses.
