Investigating the Impact of BIM Implementation on Mitigating Construction Delays in Building Projects in Bangladesh

Construction delays are a persistent challenge in Bangladesh's construction industry, impacting project timelines, costs, and overall efficiency. This study investigates the potential of Building Information Modeling (BIM) to address these delays by enhancing communication, streamlining processes, and improving project management practices. Through a comprehensive examination of BIM's effectiveness, adoption levels, and implementation challenges, this research aims to deepen the understanding of construction delay factors and promote the effective application of BIM in Bangladesh. Using a mixed-methods approach, including literature review, survey analysis, and qualitative interviews, data were collected and analyzed to assess the role of BIM in mitigating construction delays. The findings reveal insights into the main factors contributing to delays, the current state of BIM adoption, and the challenges faced in its implementation within the Bangladeshi context. Results indicate a significant correlation between BIM adoption and reduced construction delays, highlighting the potential of BIM as a transformative tool in the construction industry. Key findings include highly significant factors contributing to delays such as owner decisions, design modifications, and poor site management, as well as the emerging adoption of BIM in Bangladesh, despite challenges like lack of expertise and resistance to technology. Despite these challenges, BIM has shown promise in reducing delays, particularly in areas such as design changes, shifting owner decisions, and poor site management. In conclusion, this research underscores the importance of embracing technological advancements like BIM to address the complex challenges faced by the construction industry in Bangladesh. By leveraging BIM's capabilities, stakeholders can improve project management practices, streamline processes, and ultimately achieve timely and cost-effective project delivery.
