Abstract: CHASTE—'Construction Hazard Assessment with Spatial and Temporal Exposure'—is a conceptual model that enables forecasting of safety risks in construction projects for different trades, at appropriate levels of detail and reliability for different planning windows and managerial purposes, in a highly automated fashion. Unlike earlier models, CHASTE explicitly accounts for the fact that construction workers are frequently endangered by activities performed by teams other than their own. The risks to which workers are exposed change through time, as the activities performed and the physical environment of construction sites change. CHASTE uses a knowledge base of construction activities and probabilities of loss-of-control events, coupled with a project's construction plan and a digital building model, to forecast risk levels for work teams. It has been implemented in prototype software and tested on two projects.
