Shared Office Facilities
Shared office facilities provided by Livermore Computing are available in Building 453 (authenticated users can visit Shared Office Policies on for specifics of location and policies). The shared offices have workstations that permit access to both the classified (SCF) and unclassified (OCF) networks. They are intended for users that do not have access to the SCF network from their own offices and need a temporary location from which to work. OCF network access is provided primarily as a convenience. For general information regarding access to and use of the shared office facilities, contact the LC Hotline at or 422-4531.
