  The broader construction industry is struggling with data loss, inefficient
processes and low productivity in asset management. The remedy to these
problems seems to be the idea of Digital Twin (DT). However, the frameworks
proposed so far do not always support a solution to these problems. This paper
conducts an extensive literature review to develop a conceptual framework for
the Operation and Maintenance (O&M) phase for cubic facilities. The conceptual
framework takes into account the increasingly popular Internet of Things (IoT)
and Artificial Intelligence (AI) technologies. The presented framework, after
appropriate modifications, can also be applied to infrastructure facilities or
city fragments. The paper presents limitations and directions for further
research. The DT paradigm has been adopted and its adoption is ongoing. Its
implementation will progress in the coming years.
