The construction industry plays a significant role in a nation’s social and economic development. There cannot be much progress in the national development without construction, particularly in developing countries where there is lack of infrastructure and other basic facilities. Construction projects form a bulk of construction projects in Southern Ethiopia and are paramount in the areas of housing, business and public undertakings. For the findings of this study the data were acquired using open interviews; questionnaire examination and a case study on purposively selected construction projects in Southern Ethiopia. And the study has been conducted on 102 purposively selected players in the construction industry which included private and public sector clients, contractors, consultants, suppliers and end-users of construction projects in order to stimulate data from 36 majorly identified variables of delay that were well-known through an attentive literature review. The study begins with review of the important aspects of construction process, delays and claims observed. It then took a casual analysis to establish the extent of delays in the project, the causes for the delays and the effect of the delays on the construction project. Relative Importance Index (RII) analysis was used for the ranking of causes and effects of delay. RII results of the study showed that the major causes of delay summarized from the clients, consultants and contractors point were (1) Untimely payment & financial difficulties (RII = 0.864), (2) Variations and Change orders (RII = 0.841), (3) incomplete designs and late site handover (RII = 0.780), (4) Mistakes in contract documents (RII = 0.72), (5) Lack of appropriate supervision(RII = 0.690), (6) Construction mistakes or poor workmanship (RII = 0.662), (7) Late issuance of instructions & poor communications among parties(RII = 0.590), (8) Material procurement problem (RII = 0.530), (9) Equipment management problems (RII = 0.380), and (10) Inclement weather & Unforeseen site conditions (RII = 0.320). The study also determined the major effects of delays in the construction projects, which were (1) Increase project cost, (2) Time overrun, (3) claims and dispute, (4) Arbitration, (5) Litigation, (6) Complete termination of contracts, (7) Liquidated damages, (9) Worse the quality of work and (10)Reduce productivity. Other researchers might take comparable studies in other parts of the domain and recognize major reasons or causes for delay and effects of delays in construction projects.
