| Abstract: | In the construction industry the main issue is delay or time limitation to fully accomplish the work without any defect in the project. Generally, delay is a condition that work does not complete in an estimated time. Construction delay is a common problem in construction projects in Ethiopia and occurring in every type and phase of a construction projects. Therefore, this study was carried out to identify the major causes of delay and the mechanism to minimize delay in Ethiopia construction Work Corporation. Thirty-nine (39) project delay attributes on Cause of building projects delay and Four (4) Mechanisms to minimize delays in building projects were identified through detailed literature review and expert’s support. The study adopts quantitative methods with the help of primary data. Primary data was collected using self-administered questionnaires on 109 selected respondents from clients, consultants and contractor. This research categorized the causes of delay under four main groups of clients related, consultant related, contractor related, and external related and then assessed their impacts on cause and minimization of delay using relative importance index (RII) as a basis for analysis. The RII for all delay factors and group of categories was computed to rank the factors. The topmost influential causes and minimization of delay on Ethiopia construction work corporation project the study concluded that causes of delays under owners related delay in building construction projects. “Delays in revising and approving design document” (RII=0.73) this result shows Important 0.6 < 0.73 =0.8, causes of delays under consultants related delay in building construction projects. “Delay in approval of submittals, design drawings, and sample materials” (RII=0.71) the result shows modernly Important 0.6 < 0.71 =0.8,), causes of delays under contractors related delay in building construction projects.), “Rework due to errors during construction” (RII=0.80) this result shows Highly Important 0.6<0.86 =0.8, Causes of delays under external related delay in building construction projects. “Unforeseen site conditions” (RII=0.86)” this result shows Highly Important 0.6 < 0.86 =0.8 and “Managing ineffective planning and scheduling” is appeared to have very high impact on minimizing delays in building construction projects with (RII=0.63). results show between 0.6 < RII = 0.8 and Scale Level of Importance RII result is important in which more priorities must be given to this points to avoid delays that are caused in building construction projects. |
