The Post Earthquake Investigation Team (PEQIT) at the Office of Structure Design, Division of Structures, CALTRANS, has been organized since the 1971 San Fernando earthquake. It is an emergency response team which mobilizes quickly following a major earthquake event. The goal of this team is to collect design related bridge damage data as soon as possible right after a major earthquake event. The EQIF program demonstrates the usefulness of a GIS system during an emergency response by the Division of Structures, CALTRANS. It is effective for obtaining a lot of information in a very short period. To develop a full GIS system, a commercial software package is needed to reduce the programming effort. We are currently evaluating different GIS package to add needed functions for our future operation. The effort also includes the possibility to have a portable system which can be easily carried by the field investigation team.
