Technology Framework for Real-Time Assessment of Spatial Conflicts in Building Retrofitting

In the field of construction works planning, workspaces must be considered as limited resources, in the same way as labour crews and equipment. Being the work-related spatial information both contextual and affected by construction site's dynamics, a real-time management approach based on lean principles must be adopted. In this paper, a BIM-based serious game engine, framed within a high-level system architecture, is presented to enhance work progress management. The generation of a geometric model to perform look-ahead simulations for predicting spatial conflicts is showcased relatively to a retrofitted residential building.
