Factors Affecting Time Overrun On Building Construction Projects Under Addis Ababa City Administration: The Case Of Koye Feche Housing Project Akaki Site

Abstract

The construction industry has an important role in improving the socio-economic growth of a country. Specially for the developing countries, the construction industry is the major input for growth, employment, and infrastructure expansion. However, it has not contributed to the growth of the countries as anticipated due to limitations, drawbacks, and the various problems it has faced. Among those problems, the impact of delay in a construction project is the most significant and common. The same trend follows for Ethiopia as well. Most construction projects in Ethiopia are exposed to time overrun. It has become difficult to complete construction projects in the allocated time, cost, and quality. Therefore, this research aimed at investigating information on the factors that causes time overrun on building construction projects in Addis Ababa City administration (with a specific emphasis on the Koye Feche Akaki site) in the views of building construction stakeholders. To achieve the objective of the study a close-ended questionnaire which was designed based on the 15 factors identified from the literature review was prepared and distributed to stakeholders that have direct relation to the project considered in order to collect primary data. And secondary data was collected through office document review. After the data collection step is completed the collected data was analyzed and ranked using relative importance index. The findings from the study identified that, material shortage at the local market, contractors’ financial difficulties, inadequate/ deficiency in planning, scheduling & coordination, and payment delay for contractors were the top most delay contributory factors for the projects. While unexpected engineering problems and incomplete design at the time of tender were identified as the least contributory delay factors. And based on the results few recommendation were drawn. Some of the recommendations are as follows: the client is mostly the responsible party for financing of the project. And should be able to fulfill contractual obligations. Moreover, more attention should be given during the design phase from the consultant side to minimize the probability of change orders and avoid errors and confusions. In addition to that, contractors should plan their schedule and resource properly and avoid taking jobs in which they do not have sufficient expertise
