The George E. Brown, Jr. Network for Earthquake Engineering Simulation (NEES) is an ambitious national program to advance the study of earthquake engineering and find new ways to reduce the hazard earthquakes represent to life and property. NEES represents an unprecedented effort, in which research institutions across the country will use simulation— both physical and numerical —to develop increasingly complex, comprehensive, and accurate models of how the infrastructure responds to earthquake loadings. NEES is funded by a Major Research Equipment grant from the National Science Foundation. NEESgrid will link the NEES equipment sites into a national collaboratory. The NEES major equipment sites provide a comprehensive, shared infrastructure for performing experiments on earthquake-related phenomena.
The Tele-observation and Tele-operations (&quot;Telepresence&quot;) Team is defining resource requirements and will prototype and deploy passive and active telepresence management systems, including the creation of Labview protocols, generalized active protocols, and generalized client interfaces.
Along with the NEES equipment sites, the NEESgrid project also involves the efforts of several academic partners, each one an acknowledged leader in the effective application of cutting-edge technology.
The experiment site's NEESpop hosts a CHEF collaborative framework that unifies many NEESgrid functions in one consistent web-based user interface. Through this interface, users can correspond, schedule meetings and resourses, broadcast announcements, and chat. Users can also access and edit electronic lab notebooks. These ENotebooks can contain text, diagrams, photos, and other kinds of unstructured data needed to document an experiment.
The remote user can check the status of the equipment site's NEESgrid components and their essential services.
An equipment specialist at the equipment site designs metadata describing, among other things, what each channel of data to be captured by the DAQ system represents. This is how NEESgrid learns about the experiment's configuration. This config information is used to configure the streaming server so that it knows which DAQ channels are to be made available.
The remote user discovers, via browser-based tool, information about the experiment's configuration, and decides which data streams to subscribe to.
Near-real-time data and video streaming connections have been made, and the experiment trial begins.
An equipment specialist ends the trial.
The trial data is now available for browsing and download by remote users. The captured data and metadata are stored in a standardized open format, allowing the remote user to analyze it further.

The task of designing and creating this infrastructure has been awarded to the NCSA at UIUC.
The components of the NEESgrid system will be completed by September, 2004, when management and operation of the NEES system will be turned over to a consortium of earthquake engineer researchers and practitioners.
