AECOM Technology Corporation (NYSE: ACM), a leading provider of professional technical and management support services for government and commercial clients around the world, announced today that it has acquired SSI Services Inc. from the Vanadium Group.

With nearly 20 years of experience, SSI provides a wide array of services, including facility operations, maintenance and management; logistics support; and facility optimization analysis and planning, primarily to the U.S. federal as well as state and local governments. The acquisition strengthens AECOM’s service offerings in critical-mission environments such as federal facilities that have limited access as well as strict safety and security requirements.

“We are pleased to welcome SSI to AECOM,” said John M. Dionisio, AECOM president and chief executive officer. “SSI is very well respected within the industry for its comprehensive critical-mission support operations. The addition of SSI security experts to the AECOM team greatly enhances our ability to meet our clients’ needs in this specialty area globally.”

“Joining AECOM gives our clients access to greater services through the broad reach of the AECOM platform and creates a host of career-development opportunities for our employees,” said Matt Schneider, SSI chief executive officer.
