About Us

At SEH, we have decades of experience supporting the federal projects that are most important to you.

Serving numerous federal clients, we have partnered with a wide range of government organizations on many indefinite delivery/indefinite quantity (IDIQ) contract projects. This includes agencies across the federal spectrum, from the Department of Defense and the U.S. Army Corps of Engineers (USACE) to the U.S. Fish and Wildlife Service and Bureau of Land Management.

Across the nation, our engineers, architects, planners, and scientists are committed to helping you keep our country safe; our air, land, and water clean; our transportation systems efficient; and our national parks accessible and informative.
