Assessment of Problems in Prefabricated Concrete elements used in Addis Ababa building projects
Precast concrete is a construction product produced by casting concrete in a reusable mold which is then cured in a controlled environment, transported to the construction site and lifted into place. The basic means of such technique is the use and application of the readymade and standardized building components such as prefabricated concrete elements, modular steel components and prefabricated wood. But, the most important prefabricated building components are that the prefabricated concrete component which is widely used in the development of buildings, roads, railways ,bridges, underground tunnels, pipes and lighting poles. Because of its greater importance compared to that of cast-in-situ construction methods, prefabricated concrete elements must be understood in detail with its insignificant problems in the use of the construction industries in order to achieve the goals of a country. Hence, the basic objective of the study is the assessment and identification of problems of precast concrete components, especially in building projects. By identifying such problems, the study should provide a clear picture of the problems of PC components in the construction industry and it can fill the gap of using such components compared to that of conventional methods of construction. The study focuses on the assessment of problems, transportation & storage related factors of these elements in the construction of building projects. Generally, desk study, questionnaire survey and measurements were conducted and analyzed in eighteen sample projects for a total of 42 respondents. According to the findings of this study initial investment cost, transportation and storage cost, the requirement of heavy machines and skilled manpower are some of the major problems in the construction of prefabricated building projects. Finally, the study indicates that the transportation and storage cost are also the major challenges of the company and it recommends that governmental support for the development of factory is a viable solution to ensure initial investment cost, initiating foreign investors’ and the requirement of optimization models for cost planning in transportation and storage costs are some viable solutions.
