To carry out the foreign policy of the United States, the U.S. Department of State must communicate effectively, efficiently, quickly, and securely. The Department’s Bureau of Information Resource Management provides secure, reliable, and robust communications capabilities for the more than 300 U.S. embassies, consulates, and diplomatic missions around the world. For more than a dozen years, Tetra Tech has been providing worldwide assistance to ensure the functionality of the Department’s classified and unclassified digital, wireless and radio, telephone, and video communications equipment and computer systems and programs.

Since 2000 Tetra Tech has provided engineering, project management, and technical assistance covering the design, installation, maintenance, upgrade, remediation, and training needs of U.S. government communication equipment in missions worldwide, at the Regional Information Management Centers, and in Washington, D.C.

Our team provides program management assistance; project leadership; strategic planning; program analysis and reporting; accounting, budgeting, and financial planning and reporting; procurement, logistics, and warehousing support; software development and installation; and deployment scheduling and travel. We also research advances in communications technology, recommending enhancements to existing equipment, networks, policies, and tools. We analyze and monitor current usage and future bandwidth requirements.


Tetra Tech teams are responsible for the procurement, design, installation, and maintenance of Nortel/Avaya/Cisco PBX hardware and all associated peripheral equipment. We support more than 2,300 encrypted devices. By providing posts worldwide with VoIP technology, we are able to support more remote networks from a single location, while more efficiently maintaining the security, encryption, and separation requirements.


The overseas radio systems are used for emergency and evacuation support of U.S. citizens employed at U.S. posts. The domestic radios are used to support local law enforcement efforts, investigatory work, protection of foreign dignitaries, and protection of the Secretary of State and other U.S ranking officials. We provide operation and maintenance services, and we develop solutions for interoperability challenges.


The Department of State messaging application provides the ability to send and receive formal messages, including allowing authorized users to share classified information. We deployed the application worldwide six months ahead of schedule and $8 million under budget.
