| dc.description.abstract | Construction industry is a major player in economy of any countries by generating employment and wealth to the nations. However many projects in developing countries experienced extremely low performance in terms of time cost. One of the contributing factors to this low performance among others is variation. This is because variation can affect project cost, schedules. With this background, this study tries to identify whether variation exists or not, what causes these variations, what is their consequences, which contracting party is the more responsible in initiating these variation and which is most affected as a consequences of these causes. Based on this a questionnaire which consists of 35 potential causes, 12 possible effects and other questions which enables to achieve the objectives of the research were developed. Accordingly the study concludes that variation as one major problem in Ethiopian Federal road construction projects. Right of way or accesses to site problems, change in defined scope, lack of proper planning, lack of proper evaluations of tender documents by contractors at tendering phase and contractor’s financial problems were identified as major causes which results these variations and client/employer were identified more responsible in initiating most of the variation issues. The study also investigated; delay in project completion time, increase in project cost, suspension or hold on works, decrease in productivity and dispute among parties as a major effects and contractors as the most affected contracting party as a result of effects of variations | en_US |
