## 2 Motivation and Methodology  
In recent years, there has been a boom in the development of digitalisation technologies such as Big Data, IoT or Cloud Computing. However, these technologies are still remote from the methodology traditionally used in the lifecycle of a project. The combined use of these technologies together with BIM offers great possibilities in the field of construction and civil engineering. This review has been carried out with the aim of gathering the most relevant procedures and advances in the use of BIM together with some of these new technologies in the framework of SC. This combined use of technologies can bring significant potential benefits throughout the project lifecycle. However, fewer articles on the FM phase are found among the published literature, so the research has been oriented towards this phase. This study shows a thorough state-of-art based on scientific published literature related to the concept of SC. In the last two decades, a wide amount of research has been developed, focused on what BIM may bring to the Construction Industry as well as studies about the life span of civil engineering projects. In a first line of research, this study started with the search for the concept of BIM to see how and what it has been related to in the most recent research. ICTs have appeared in recent years. The integration of ICTs with BIM is being developed to ensure that the three-dimensional model becomes a dynamic, accessible, secure, and an updated repository of information. There is a wide variety of ICTs applied to the Construction Industry, so the research was focused on searching articles by keywords. The main drivers of SC have been determined by five ICTs concepts. These topics are generic and overlapping, so the focus of the research was centred on FM for transport infrastructure. Table 1 shows the keywords searched for. The combination of these 10 concepts, together with their associated terms such as immersive technologies, Industry 4.0, Digital Twin, Application Programming Interface (API), unmanned vehicles, database (DB), CC or management platform) were the research basis. Furthermore, research was performed on successful cases where BIM was implemented \begin{table}
\begin{tabular}{c c} \hline \hline
**ICTs** & **Construction** \\ \hline Geographic Information System (GIS) & Building Information Modelling (BIM) \\ Internet of Things (IoT) & Construction 4.0 \\ Motion Capture & Operation and Maintenance (Q&M) \\ Big Data & Facility Management (FM) \\ Blockchain & Transport infrastructures \\ \hline \hline \end{tabular}
\end{table} 
Table 1: Main keywords searched. together with some ICTs in the transport infrastructures lifecycle (tunnels, bridges, roads, hydraulic works), in the operation and maintenance (O&M) of large buildings or heritage preservation (HBIM). Figure 1 shows the flowchart used. A literature search on BIM in transport infrastructures was carried out first, identifying new trends, focusing this research on the FM phase and the use of relevant ICTs. From these articles, the main topics and keywords were identified in order to return to search for new literature. If the research dealt with any of these topics, or at least BIM in transport infrastructure, it was categorised according to the type of infrastructure and by ICT. At first, the building category was discarded; however, it is in this sector where there is a greater number and more relevant advances in the joint use of BIM-ICT applied to FM, so this category was added. Figure 1: Flowchart used in this state of the art. By using the tool for visualising indexed academic publications VOSviewer [71], the relationships of the main referenced articles keywords are shown in Figure 2. VOSviewer is a software tool for constructing and visualising bibliometric networks. These networks are generated using points, lines and colours. The size points represent co-occurrence aggregates such as the author or keywords, while the lines represent the relationships established between them [72].
