The United States Army Corps of Engineers (USACE) is made up of some 34,600 civilian and 650 military men and women. The Corps' mission is to provide quality, responsive engineering services to the United States, including:
- Planning, designing, building and operating water resources and other civil works projects
- Designing and managing the construction of military facilities for the Army and Air Force
- Providing design and construction management support for other Defense and federal agencies
The Chief of Engineers has separate and distinct command and staff responsibilities. As a staff officer at the Pentagon, the Chief advises the Army on engineering matters and serves as the Army's topographer and the proponent for real estate and other related engineering programs. As commander of the US Army Corps of Engineers, the Chief of Engineers leads a major Army command that is the world's largest public engineering, design and construction management agency. His office defines policy and guidance and plans direction for the organizations within the Corps.
The US Army Corps of Engineers Headquarters is made up of an Executive Office and 17 Staff Principals. The Headquarters, located in Washington, DC, creates policy and plans future direction of all the other Corps organizations.
The Corps is organized geographically into eight divisions in the US and 41 subordinate districts throughout the US, Asia and Europe. The districts oversee project offices throughout the world. Divisions and districts are defined by watershed boundaries, not by states.
The Engineer Research and Development Center (ERDC) is the US Army Corps of Engineers research and development command. ERDC consists of eight unique laboratories.
Research support includes:
- Mapping and terrain analysis
- Infrastructure design, construction, operations and maintenance
- Structural engineering
- Cold regions and ice engineering
- Coastal and hydraulic engineering
- Environmental quality
- Geotechnical engineering
- High performance computing and information technology
- Huntsville, US Army Engineering and Support Center (CEHNC) - provides engineering and technical services, program and project management, construction management, and innovative contracting initiatives, for programs that are national or broad in scope or not normally provided by other Corpsí elements
- Transatlantic Programs Center (CETAC) - supports US government programs and policies overseas
- Finance Center, USACE (CEFC) - supports the operating finance and accounting functions throughout the US Army Corps of Engineers
- Humphreys Engineer Center Support Activity (CEHEC) - provides administrative and operational support for HQUSACE and Corps Field Offices
- Marine Design Center (CEMDC) - provides total project management including planning, engineering, and shipbuilding contract management in support of Corps, Army, and national water resource projects in peacetime, and augments the military construction capacity in time of national emergency or mobilization
- Institute for Water Resources (IWR) - supports the Civil Works Directorate and other USACE offices by developing and applying new planning evaluation methods, polices and data in anticipation of changing water resources management conditions.
- 249th Engineer Battalion - generates and distributes prime electrical power in support of warfighting, disaster relief, stability and support operations as well as provides advice and technical assistance in all aspects of electrical power and distribution systems. It also maintains Army power generation and distribution war reserves.
