DESCRIPTION:Dr. William J. O’Brien\nAbstract\nAs part of a larger moveme
 nt to ubiquitous computing where sensors and \nmobile computers are everyw
 here\, the intelligent jobsite is becoming a \nreality. Applications such 
 as structural health monitoring and materials \nmanagement that use sensor
 s and mobile computing devices are being \ndeveloped and deployed commerci
 ally. There are also specific sensors and \napplications for construction 
 safety\, such as location monitoring. \nHowever\, these applications are p
 urpose driven and are not deployed for \nreuse.  Yet the intelligent job s
 ite will have a plethora of sensed \ninformation.  This creates an opportu
 nity for workers to access data in \nan ad hoc manner as they move through
  a site\, leveraging data for \nmultiple purposes. However\, re-tasking an
 d reuse of sensors in a dynamic \nsetting presents significant challenges 
 including ad hoc identification \nof sensors in a local environment\, gene
 ralization of data\, and the use \nof dynamic information for decision sup
 port. This talk describes these \nchallenges in the context of constructio
 n safety.  Particular focus is \ngiven to the decision support challenges.
  Research objectives include \ndefining safety in a monitored environment\
 , deploying decision rules in \na distributed environment first assuming p
 erfect information\, and\, \nfinally\, distributed decision support with i
 mperfect information. The \nchallenges of imperfect data parallel some of 
 those faced by researchers \nin structural health monitoring including mod
 el based interpretation of \nuncertain data and system identification. We 
 draw parallels where \nappropriate and look for open discussion.\n\nAbout 
 the Speaker:\nDr. William J. O’Brien focuses his professional efforts on
  improving \ncollaboration and coordination among firms in the design and 
 \nconstruction industry. Dr. O’Brien is an expert on construction supply
  \nchain management and electronic collaboration\, where he conducts \nres
 earch\, teaches and consults on both systems design and implementation \ni
 ssues. He was the lead editor on the recently published Construction \nSup
 ply Chain Management Handbook (CRC Press). Dr. O’Brien is currently \nan
  Associate Professor in the Department of Civil\, Architectural\, and \nEn
 vironmental Engineering in the Cockrell School of Engineering at the \nUni
 versity of Texas at Austin.
