An object-based conceptual model for ICT-based situational awareness of the construction process

Due to the dynamic nature of the construction process, situational awareness (SA)is essential for the stakeholders to perceive, understand and project the real situation of the construction process to support their decision making. SA requires a collection, integration, and interpretation of information to reveal the occurrence of the real-world elements and environment. Nowadays, with the emerging ICT implementations in the construction domain, the volume, content, and quality of data and information that enables situational awareness for the construction process have increased. This provides the potential of establishing an ICT-based SA system for the construction process. However, SA information of construction process has been collected with point solutions so far, which does not allow true SA considering multiple information streams together. In order to integrate the information via multiple ICT systems to support the establishment of ICT-based SA system for the construction process, this paper presents an object-based conceptual model. This model offers an initiative of conceptualizing the objects in the construction process and intend to be a reference for integrating the information from various ICT systems.Peer reviewe
