Aecom Technology (NYSE: ACM) is an engineering firm that specializes in transportation infrastructure. The company provides design services for projects including the new PATH terminal at the World Trade Center site, New York's Second Avenue Subway renovation, and the 1088-meter-span Sutong Bridge in China.

While technical engineering services account for a large percentage of Aecom's total business, the company has been actively growing its Management Support Services (MSS) division as well. MSS projects can range from developing global supply chains for humanitarian groups to establishing natural disaster contingency plans for corporations. The business unit has posted double-digit revenue gains in each year since 2005. ^[1] Much of this growth has come from contracts with the U.S. Department of Defense, which relies on commercial contractors for most of its logistics support and maintenance services in Iraq and Afghanistan. The intersection of the Iraq troop surge of 2007-08 and the growing need to maintain and overhaul aging equipment in the field has been a boon for Aecom which has grown into one the military's top trainers/managers of maintenance service personnel.
