Abstract
It has been widely accepted that developing and maintaining a cyber system (e.g. Building Information Modeling) representing the corresponding physical system is a promising approach to improve decision-making in construction. However, to bridge the bi-directional coordination between the virtual and the physical system is the prerequisite for the improvement, yet this is the most challenging part for researchers and practitioners. Using tower crane as a case study, the primary aim of this study is to propose a cyber-physical system by articulating its system structure, bridging technologies, and its computational applications. Particularly, a smart core is developed to integrate real-time information on physical machinery on site with their ‘cyber twins’ in virtual, which is developed as a web-based platform. A LEGO® tower crane is built and simulated in lab, showing the cyber and physical systems can be well bridged to facilitate safety management and resource utilization in construction projects.
