الملخص

Construction projects are vulnerable due to their unique qualities, and they are influenced by a variety of external and internal causes. Because of their actions, a large number of project participants produce variances in the scope and design of the projects. Natural causes can also play a role in variation requests for construction projects. Variations have a number of negative consequences in construction projects. The building sector is also influenced by a number of elements that are unique to the country. In this context, the goal of this study is to learn more about the causes and consequences of building project variances. A quantitative poll of engineers and construction management experts working in public works was used in the study, in addition to a thorough literature review public and private development projects The study concludes that differences are caused by a lack of coordination among the parties and changes in specifications by the owners, based on a review of the literature and a survey. The report also shows that the most significant impacts of building project variances are schedule overruns and cost increases. According to the findings of the survey, contracting organizations examine price terms and timing agreements when signing contracts. The study has identified a few topics for future research and knowledge expansion in the subject.
