The architecture, Engineering, and Construction industry faces an ongoing digitalization. This study investigates how infrastructure projects practice cost estimation, what is hindering automated cost estimation, and how automated cost estimation can be further developed. A case study with integrated project delivery was studied. The collected data were categorized and analyzed after three cornerstones for digital transformation: people, process, and technology. This study finds current practices time-consuming, error-prone, and inefficient. However, modelbased cost estimation can result in higher efficiency and fewer errors. Concerning people, relevant training and mindset identified crucial elements. Concerning process, increased workload due to integrated project delivery, time pressure, and problems with attaching correct classification codes to objects in BIM resulted in incomplete models hindering automated cost estimation. The identified hinders concerning technology were not worth mentioning. Suggested improvements include relevant training and alignment between today's object-oriented BIM and the process-oriented standard specification of work for infrastructure projects
