Parsons has secured a $91 million contract extension from the Department of State to continue providing security installation and support services for American diplomatic missions worldwide.
The award represents the seventh option year on the Overseas Security Installation Services II, or OSIS II, contract, a 10-year program with a total ceiling of nearly $1.12 billion, Parsons said Monday.
What Does the OSIS II Contract Extension Cover?
Under the extension, Parsons will continue delivering integrated protection services at U.S. embassies, consulates and other diplomatic facilities overseas. According to the company, its work under OSIS II has supported security operations at more than 265 diplomatic sites globally.
The services cover operations support and delivery of advanced access control systems, biometric technologies and counter-unmanned aircraft systems.
The company’s role also involves adapting security offerings to evolving operational conditions and threat environments faced by U.S. diplomatic personnel abroad.
Carey Smith, chair, president and CEO of Parsons, said the extension reflects the company’s focus on supporting State Department security missions in complex environments.
“Our team is dedicated to anticipating and countering tomorrow’s security challenges,” the eight-time Wash100 Award recipient said. “We’re proud to deliver innovative technology and operational expertise that advance the State Department’s efforts to protect personnel, facilities, and assets and accomplish mission objectives amid an increasingly complex global landscape.”
How Does the Extension Fit Into Parsons’ Broader Security Work?
Parsons said the OSIS II option-year award supports its continued growth in defense and global security programs. Recently, the company won contracts supporting national security infrastructure programs and border security projects in the Middle East.
