Abstract: Building Information Modeling (BIM) offers a variety of tools to help a wide range of stakeholders in the construction industry. There has been substantial research on the advantages and challenges of implementing BIM for large and medium-sized construction companies; however, there is a dearth of research on the benefits and challenges faced by smaller construction firms when adopting and implementing BIM. Thus, this study focuses on developing a BIM Adoption Roadmap that can be used as a starting point by small-sized construction companies. To achieve this objective, first, medium and large-sized construction firms who already have implemented BIM in several of their projects were interviewed. The purpose of these interviews was to understand what motivated these firms to start using BIM. Based on the findings from the interviews, a set of survey questions was prepared and distributed among all types of construction firms in order to identify which BIM functions they use. The semi-structured survey included questions regarding company demographics, innovativeness, and BIM-specific topics. A second survey was sent out to collect feedback on the proposed BIM Adoption Roadmap from large and small-sized construction companies. The roadmap for small-sized construction companies aims to help them adopt at least one of the BIM functions identified in this study. The idea is to have small-sized construction companies to start implementing simple and easy BIM functions in some of their projects and then explore other BIM applications in the future.
