The European Parliament released the 2030 Digital Compass, identifying the construction
sector as one of the five key ecosystems in the digital transformation process. A
Construction 4.0 maturity model (C4M) was created to lead companies through their
digital transformation journey. This research aimed to justify the model categories
of the developed C4M using a qualitative case study methodology. The case study highlighted
the practical relevance of the model by identifying three areas within the C4M that
were the main drivers of digital transformation: cloud-based systems, knowledge management
and system integration to drive digitalisation further. It was revealed that the digital
processes in the design, production, and construction phases are connected to each
other through system integration
