Abstract
As part of a larger movement to ubiquitous computing where sensors and
mobile computers are everywhere, the intelligent jobsite is becoming a
reality. Applications such as structural health monitoring and materials
management that use sensors and mobile computing devices are being
developed and deployed commercially. There are also specific sensors and
applications for construction safety, such as location monitoring.
However, these applications are purpose driven and are not deployed for
reuse. Yet the intelligent job site will have a plethora of sensed
information. This creates an opportunity for workers to access data in
an ad hoc manner as they move through a site, leveraging data for
multiple purposes. However, re-tasking and reuse of sensors in a dynamic
setting presents significant challenges including ad hoc identification
of sensors in a local environment, generalization of data, and the use
of dynamic information for decision support. This talk describes these
challenges in the context of construction safety. Particular focus is
given to the decision support challenges. Research objectives include
defining safety in a monitored environment, deploying decision rules in
a distributed environment first assuming perfect information, and,
finally, distributed decision support with imperfect information. The
challenges of imperfect data parallel some of those faced by researchers
in structural health monitoring including model based interpretation of
uncertain data and system identification. We draw parallels where
appropriate and look for open discussion.
