AB  - High rise buildings signify an element of the country’s economic power and a sign of advantage to the country and also consumes a large number of people with a piece of land. Addis Ababa city is witnessing huge demographic expansion due to migration from surrounding rural areas, leading to urban stretch, housing demand, rise in the cost of land. Given this demand, though high rise structures have become a solution. When accomplishing these complex and huge high rise building structures, many problems affect the construction process. The objectives included an assessment of challenges, identifying the main factors which affect the construction process of high rise building construction. This research involves both qualitative and quantitative approaches for data collection and analysis.
