Building Information Modeling Capability in Mitigating Change Orders and Cost Overrun

Abstract

The Jordanian construction industry faces notable challenges, particularly about variation orders (VOs), contributing to budget overruns and project delays. The Jordan Engineers Association poll in 2020 found that variation orders (VOs) accounted for 23% of cost overruns in construction projects in Jordan. Research undertaken by the Ministry of Public Works and Housing in 2019 found an average of 948 change orders per year, representing 25.5% of the total value of the projects. Our study introduces a highly tailored evaluation method to gauge the effectiveness of Building Information Modelling (BIM) in addressing these challenges. The study assesses the efficacy of Building Information Modeling (BIM) in diminishing variation orders (VOs) by examining sophisticated BIM functionalities. The study employs an intricate case study and diverse construction project data to construct a model that assesses the capacity of BIM to reduce project modifications and enhance cost efficiency. A novel approach has been devised to enhance the optimization of building information modeling (BIM) in the construction industry of Amman, Jordan. The objective of the concept is to minimize variation orders (VOs) and enhance project management. The study employs research approaches, such as semi-structured interviews and questionnaires, to pinpoint the essential abilities contributing to change orders. After comprehensively analyzing BIM's global and Middle Eastern applications, we created the model. The findings indicate that enhancing Building Information Modeling (BIM) capabilities can effectively mitigate the occurrence of variation orders within Jordan's building sector. The approach promotes the cooperation of stakeholders, sets quantifiable benchmarks, and strategically employs BIM for preliminary risk assessment. This research substantially enhances the productivity and cost-effectiveness of construction projects in Jordan, offering vital insights for professionals and policymakers.
