| Abstract: | Building projects in Addis Ababa are suffering a wide range of performance challenges. The goal of this study was to evaluate the delay factors that impact the performance of building construction projects. Through a thorough analysis of the literature, eighty-one (81) project delay factor characteristics were found. A structured questionnaire survey was undertaken among stakeholders, including consultants and contractors on selected building projects, to obtain their perspectives on the factors of project delays. This study classified delay factors into four categories: consultant-related, contractor-related, client-related, and external-related, and then examined their influence on delay using the relative importance index (RII) as a foundation for analysis. Primary data was acquired from 87 respondents through questionnaire. Relative importance index (RII) was utilized for analysis to identify important delay factors impacting project performance of building construction projects. The RII was computed for each delay factor and set of categories in order to rank the factors. Slow decision making, unanticipated surface and subsurface circumstances (such as soil, high water table), inefficient project planning and scheduling, and periodic work stoppage owing to cash flow restrictions and escalation of local material prices were among the study's findings. According to the study, the client related category had the most influence, followed by external related, contractor related, and client related had the least impact. The study also recommended a series of actions that directly resolve the issues raised for each stakeholder as well as the external related delay factors such as clients should collaborate closely with other stakeholders to improve project site delivery timeliness, contractors provide enough work planning and scheduling, as well as skilled site management and monitoring and consultants should ensure that proper site investigations are carried out both during the feasibility study and the conceptual design to guarantee that necessary procedures are taken during the detailed design to avoid work suspension during the construction phase to resolve design difficulties. |
