Press Release

HOUSTON – (August 17, 2022) – KBR (NYSE: KBR) announced today it was awarded a $20 million contract by the United States Geological Survey (USGS) Albuquerque Seismological Laboratory (ASL) for sustained support of more than 330 operational or proposed stations in 69 countries, including approximately 230 stations in the continental U.S.

Under the scope of this cost-plus-fixed-fee recompete contract, KBR will provide support for the deployment, operation, maintenance, and repair of USGS domestic and global seismographic systems. The KBR team will support the installation and operation of the USGS component of the Global Seismographic Network, a permanent digital network of more than 150 seismological and geophysical sensors.

This work will take place out of the USGS ASL in Albuquerque, New Mexico, adjacent to Kirtland Air Force Base. KBR will also provide support to the US N4 Network, the Advanced National Seismic System backbone network, additional regional networks, and earthquake aftershock deployments. Along with operational support to these networks, KBR support will ensure the quality and integrity of the data. This data is used for real-time seismic monitoring by the USGS National Earthquake Information Center, for tsunami warnings by the National Oceanic and Atmospheric Administration (NOAA) Tsunami Warning Centers, for nuclear test monitoring by both the Comprehensive Test Ban Treaty Organization and the U.S. Air Force, as well as for scientific research by a broad community of international users.

This tech-heavy contract also includes support for instrument testing and development, depot operations, data collection and quality control, inventory management, shipping coordination, software engineering, and warehouse logistics. The strategic win for KBR includes one base year, four option years, and one six-month extension option.

“KBR scientists and engineers are changing how we learn about and protect our planet every day,” said KBR Government Solutions U.S. President Byron Bright. “This crucial research never ends, and we are excited to continue supporting important studies of the landscape of the Earth, its natural resources, as well as the natural hazards that threaten it.”

KBR has supported USGS seismic networks for 39 years. Throughout its experience in environmental monitoring, KBR has also worked with government agencies including NOAA, the National Weather Service, and the National Aeronautics and Space Administration to support their Earth and planetary science and data processing, analysis, and visualization operations.
