Conservation and rehabilitation of cultural Heritage is gaining international concern due to many reasons the most important of which is retaining the cultural identity of countries. The Cultural heritage buildings in Egypt are considered a national treasure as they are a living proof of Egyptian ancient civilization, with unlimited potential for national income through tourism by exhibiting iconic cultural landmarks equipped with modern services. This paper aims at developing a framework for identification of maintainability measures for cultural heritage buildings in Egypt. Using the latest technologies in archiving and documenting of buildings features, three-dimensional laser scanning, the influencing deterioration factors on buildings will be identified and recorded. The resulting pool of factors is analyzed to identify the best representing group which will finally be benchmarked against maintenance fundamentals to produce a grading scale. Later, through the integration of the 3D model into a 3D GIS, a map will be produced for buildings in Cairo showing their grading according to the performed study.
