Evaluating the Impact of Building Information Modelling on Sri Lankan Highway Construction Projects

<p dir="ltr"><i>Sri Lanka, as a developing nation, has witnessed substantial growth in road infrastructure, with the highway construction sector playing a vital role in the country’s socio-economic development. However, these projects are often affected by significant time and cost overruns. This study explores the potential of Building Information Modelling (BIM) to enhance time and cost efficiency in Sri Lanka’s highway construction projects. It examines the current level of BIM adoption, prevailing project challenges, barriers to implementation, and the impact of 3D, 4D, and 5D BIM dimensions on project outcomes. A quantitative approach was adopted, using structured questionnaires targeting professionals in the highway sector. The findings reveal that BIM adoption remains limited, particularly beyond 3D applications, due to factors such as low awareness, high initial investment, and inadequate policy support. Nonetheless, the perceived impact of BIM particularly in improving design coordination, project scheduling, and cost management is significantly high. The study concludes by offering strategic recommendations, including capacity-building, financial incentives, and the development of national BIM standards, to accelerate adoption and promote more efficient, resilient, and sustainable highway construction practices in Sri Lanka. The study also offers strategic recommendations to address barriers to BIM adoption, fostering more efficient and sustainable highway construction practices in Sri Lanka.</i></p>
