In recent years, Construction 4.0 (C4) has emerged as a pivotal concept representing
the digital transformation of the construction industry by integrating advanced technologies
such as Building Information Modeling (BIM), the Internet of Things (IoT), Artificial
Intelligence (AI), robotics, and big data analytics. Despite the potential benefits,
construction organizations often encounter difficulties in implementing these technologies
systematically due to a lack of digital maturity. This paper investigates the digital
maturity of a construction organizations through the development of an ontology-based
fuzzy engine aimed at assessing digital maturity and providing strategic recommendations.
Utilizing Business Process Model and Notation (BPMN) 2.0, we model the digital transformation
steps derived from the Construction 4.0 Maturity Model (C4MM). A case study of a Hungarian
construction company illustrates the practical application of our methodology, highlighting
the key phases of digital transformation and the role of BPMN and ontology in measuring
digital maturity. The findings emphasize the importance of aligning business and IT
strategies, continuous improvement, and strategic innovation management in achieving
successful digital transformation.
