Integrating BIM and multiple construction monitoring technologies for acquisition of project status information

Although novel construction tech systems have been developed to monitor construction sites, each collects data in isolation. We present an event processing model (EPM) that applies multiple monitoring technologies in parallel and a set of algorithms to interpret data from the multiple streams for operations control. In a full-scale lab experiment, multiple monitoring systems were applied to monitor workers as they built drywall partitions with a variety of systems and finishes. Data from the different streams were merged to establish what work was done, by whom, where, and for how long. The results suggest that collecting, merging, and interpreting diverse data streams using a multiple monitoring technologies system on-site can provide more complete and more accurate project status information than can be obtained from the use of any individual technology. This is essential for the automation of project progress monitoring, which is important in automating production planning and control tasks.
