Building Information Modeling (BIM) technology adoption and implementation in the Sri Lankan Construction Industry; First part – The diagnosis An Honors Thesis submitted in partial fulfillment of the requirements for Honors in Civil Engineering & Construction Management. By David Dylan John Under the mentorship of Dr.Marcel Maghiar ABSTRACT The first of a two-part study to assess the adoption and implementation levels of Building Information Modeling (BIM) in the Sri Lankan Construction industry was designed using both quantitative and qualitative inquiries. The research conducted was an assessment of the existing conditions which is referred to as the diagnosis phase of the project to be used as a foundation for further study and exploration in the second phase; the prescription phase. The focus on the diagnosis phase was to better understand the industry environment for implementing technologies that takes into account the opinions and expertise of the different construction professional disciplines, including Design, Engineering and Project Management disciplines and also examines the perceived challenges to the adoption of BIM as shared by these professionals through an online survey and multiple personal interviews. Existing conditions of the construction industry in Sri Lanka were also studied in attempting to understand the background of perceived challenges and they were considered in the proposed preliminary strategies recommended in this paper for further exploration in the second phase of this study.
