description: This time the Ethiopia government gives its attention in the provision of infrastructure as<br> it is the basic for the development of one country. In reflection of this consent Design and<br> Construction of new Water supply Projects are widely seen. So many private (domestic<br> and foreign) and governmental organization are participating on the sector in the study,<br> design, construction and supervision field.There is an increase in the number of<br> construction projects experiencing extensive delays leading to exceeding the initial time<br> and cost budget.<br> The main objective of this research were to assess Causes and Effects of delay on<br> „Legedadi Deep Wells Water Supply Design and Construction Project (Phase-I). As<br> per the original signed contract agreement, the project is supposed to be completed in 12<br> months with the total allocated budget of ETB 1.35 Billion while due to time overrun the<br> project have been completed in 15 months and consumed at the end of the project ETB<br> 1.41 Billion which is higher by ETB 0.06 Billion or 4.44% than the contract amount<br> which creates challenges to allocate additional budget on the client side, inefficient<br> service delivery on the project owner, Addis Ababa Water and Sewerage Authority.<br> The study adopts quantitative and qualitative methods with the help of primaryand<br> secondary data. Primary data was collected using self-administered questionnaires on 54<br> respondents and key informant interviews with 15well experienced in such specific water<br> supply construction projects selected from the project owner, consultant, contractor and<br> subcontractors. Secondary data was collected through reviewing of project<br> documents.Such as; BOQ, Contract agreement, design documents, formal communication<br> letters, and change orders etc.<br> <br> Respondents were asked to rank the importance general and specific factors of delay<br> causes using five points scale (1=Very low, 2= Low, 3= Average, 4= High and 5= Very<br> High)and the analysis shows that, top causes of project delay were related to the Client,<br> Consultant, Contractor and sub-contractors.<br> Major findings of this research are:<br>  The construction work was started based on design prepared on inaccurate inputs and<br> assumptions, insufficient field investigation due to unrealistic three months deign<br> period.<br>  ETB 60,000,000 additional cost (Variation) incurred and the Employers plan to<br> collect ETB 20,007,000 from water selling in three month time has not been<br> achieved.<br>  Due to incorrect Engineering cost estimation excess Pipes and materials purchased<br> from abroad and ETB 81,846,397.81 Employers capital is unnecessarily tied up<br> because total design length has been 107.52km and after project completion the actual<br> total installed length becomes 89.48km which is less by 18.05km.<br>  Promise has been announced repeatedly to the public through mass media about the<br> delivery day of potable water to the residents of condominium houses in the<br> expansion area. However, the project has been completed and put into service after<br> Three month delay and this creates public grievance due to low performance of the<br> project owner.<br> The study suggested that current project planning, monitoring and evaluation system,<br> starting from study/design stage up to commissioning date have to be improved by<br> adopting the right tools and tested procedures, assigning the appropriate staffs from both<br> the project owner and the consultant, establish accountability and by applying timely<br> knowledge based decisions so that, causes and effects of delay can be managed.<br> At large, research needs to continue in order to refine and find more effective mechanism<br> to minimize if not avoid, causes and effects of project delays which are currently a<br> chronic challenge of our country, Ethiopia.
