Leveraging BIM technology for improved accuracy in detailed cost estimation in Sri Lanka

Detailed cost estimation is the process of predicting the cost of the project at workface level. However, traditional methods of detailed cost estimation encounter various challenges in achieving precise cost estimation. To address these challenges, modern techniques have emerged in the field of cost estimation. Building Information Modelling (BIM) has emerged as an efficient solution for addressing challenges in construction projects. This study investigates the adaptability of BIM for detailed cost estimation. The research adopted qualitative approach. Data were collected using two rounds of Delphi interviews with 14 experts in detailed cost estimation and BIM. Code-based content analysis was used to analyse the data. The study provides empirical evidence showcasing the potential of BIM effectively addressing the challenges encountered in detailed cost estimation. By focusing on the perspective of consultant quantity surveyors in Sri Lanka, findings underscore the significant role of BIM in enhancing the accuracy and efficiency of detailed cost estimation processes for improved project outcomes. The findings highlight further research opportunities and contribute to the understanding of BIM's impact on cost estimation. The findings can use to enhance the practical implementation of BIM by intervening to form more partnerships among application developers and industry leaders.
