About Interagency Support





The U.S. Army Corps of Engineers, through its Interagency and International Services program, provides planning, engineering design and construction management, environmental services, and technical assistance related to water, natural resources, buildings, and infrastructure. Assistance can vary from providing highly specific technical advice to complete program management services.



           ~ Through deeds, not words, we are BUILDING STRONG® ~

  • Funding for these services is provided by the requesting entity. Reimbursable support is arranged through the execution of a written agreement.
  • The USACE support to other agencies helps them meet their program challenges while avoiding duplication of federal capabilities and agency start up and closeout activities. Under the USACE IIS program, state and local governments are able to access USACE-unique support capabilities.
  • The IIS program also enables other government agencies and the private sector to access cost-saving technologies and expertise from USACE laboratories and technical centers of expertise.
  • The USACE, through its IIS program, functions largely as a contract manager using the talents of the private sector to accomplish actual tasks. Highly competent government management support and private sector technical support is a combination that best serves the public interest and specific requirements of our IIS partners and partners.

What Our Partners Say

USACE is providing great services and ICE will continue to partner and perform construction throughout the nation and territories. ~Program Director, Owned Facilities, US Immigration and Customs Enforcement
"Working with your members was a great experience and I don't know if we will ever be able to express enough thanks for the time and extremely valuable training provided." ~Justin Proulx, USACE Detroit District
I have worked with the USACE Buffalo District staff throughout that entire time and have learned to use them as my "gold standard". Not only do they supply the needed support for projects, they exemplify what the highest rated products should look like. I wouldn't hesitate to refer them to anyone else looking to use the Buffalo District staff on a project. ~Demaree Collier, US EPA
"This idea of jointness has morphed from a best practice to a necessity. In a time of fiscal constraint and austerity, this is the way to go." ~Randy Gallegos, Chief of Border Patrol Detroit Sector
