Our Infrastructure Legacy

The Leidos infrastructure, environment, and security business builds on a proud legacy created by SAIC and key acquisitions. With roots in science and technology, systems integration, power systems, and business consulting, our rich history gives us a unique perspective to design, connect, and protect intelligent infrastructure.  



SAIC combined a foundation of applied science and advanced technology with the commercially focused subsidiaries of SAIC Energy, Environment & Infrastructure, LLC and SAIC Constructors. Grounded in SAIC’s long-standing ability to transform science to solutions, the multifunctional team of more than 3,000 professionals, including engineers, scientists, and technologists, helped government and commercial customers solve their complex engineering challenges. SAIC was ranked in more than 50 industry lists of leading companies and in 2012 was recognized as a top system integrator, program management, environmental, and design firm.
