Projects Including NGL

The goal of the PEER Lifelines program is to improve seismic safety and reliability of lifeline systems. The projects in this program are mostly user-driven research projects, with strong collaboration among sponsoring lifelines organizations and PEER researchers. The PEER Lifelines program has successfully brought together multidisciplinary teams of practicing engineers (geotechnical, structural); scientists (geologists, seismologists, social scientists); funding agencies (Federal, State of California, private industry); academicians, and end-users. PEER Lifelines research projects are mainly funded by the California Department of Transportation and the Pacific Gas & Electric Company.
