As the coordination of resources' flow during location-based construction is complex due to limited space and simultaneous movements, management systems have been extended by adding a control stage to handle deviations from the initial schedule. However, a suitable information system has yet to be established. Therefore, a combined digital twin and locationbased management system was developed. The digital twin concept relies on continuous, realtime data collection to provide information about the project's status. The combination of both methods facilitates effective, data-based production planning of the resources' flow over time and space. The proposed system offers the ability to proactively manage real-time information for ongoing location-based work through discrete event simulation. For improved understanding among stakeholders, the simulated processes are visualised in a 4D game engine. In an exploratory study, the system's effectiveness was demonstrated by using literature-based changes in productivity rates during the construction of finishing work in a high-rise building. The discrete event simulation results indicate that by ordering reasonable actions in response to construction deviations, a high level of resource efficiency can be maintained. This highlights the importance of using real-time data in location-based construction projects.
