Abstract | The Jordanian construction industry faces significant challenges with order variations. A study conducted by the Jordanian Association of Engineers in 2020 revealed that variation orders were responsible for 23% of the cost and budget overruns in Jordanian construction projects. Research has shown that approximately 60% of construction projects experience time overruns of up to 30% of the original project duration and cost increases of up to 25% of the planned budget due to these orders. Current mitigation efforts have limited effectiveness. This study aimed to assess the capacity of Building Information Modeling (BIM) to mitigate variation orders in the Jordanian construction industry. It achieved this by collecting data through a comprehensive review of scientific literature and comparing best practices for its adoption and application.The research, conducted in 2024, employed mixed methods, following a sequenced design. The study started with a qualitative exploratory phase involving interviews with construction experts to identify the reasons for variation orders in the Jordanian construction sector. This was followed by a quantitative analysis phase, where the data collected from these interviews was analyzed by 126 grade-A contractors, engineers, and government sector owners using "Minitab," a statistical software. This approach ensured that the research findings reflected the industry's needs and challenges. The study confirmed that BIM is effective in significantly reducing variation orders in Jordanian construction projects. Indicators from the research suggest that BIM can address many issues related to cost overruns and project delays. The research identified best practices for the adoption and application of BIM in countries like the United States, the United Kingdom, Sweden, and Australia. These practices can be adapted to the Jordanian context to enhance the effectiveness of BIM. Common causes of variation orders were identified and analyzed, showing that BIM helps mitigate these causes by providing better project visualization, coordination, and planning. This research confirms the ability of BIM to mitigate variation orders within the Jordanian construction industry. This study has opened the door for several future initiatives to enhance the adoption of BIM in Jordan. Recommendations include promoting the adoption of BIM through targeted training programs, encouraging the development of policies that support BIM integration in construction projects, and conducting further research to explore the long-term benefits of BIM in reducing project variations and improving overall efficiency. This research contributes to the growing literature on BIM and its potential to transform the Jordanian construction industry by addressing significant challenges related to variation orders.
